Typical ProMelt Snow Melting Applications

ProMelt snow melting systems are commonly installed in:

• Driveways
• Garage entrances
• Walkways and entryways
• Outdoor stairs and ramps
• Patios and paver surfaces

ProMelt Mats and ProMelt Cables can also be combined to fit custom layouts and irregular outdoor areas.

Phase 1 - Designing the System

Heating performance is never guaranteed.

The amount of heat required to melt snow and ice depends on several environmental factors including:

• Air temperature
• Ground temperature
• Wind speed
• Sun exposure
• Humidity
• Snowfall intensity

When designing a snow melting system, consider the expected level of performance for the installation area.

Systems may be designed for either average winter conditions or extreme weather conditions depending on the project requirements.

Location-specific heat loss calculations are recommended when determining the required Watts per Sq. Ft.

STEP 1.1

Determine the areas where snow melting is required.

Typical ProMelt applications include:

• Driveways
• Walkways
• Patios
• Permanent ramps
• Masonry steps and benches
• Shipping docks
• Garage door thresholds and seals

ProMelt Mats and Cables may be used in residential or commercial outdoor applications where snow or ice accumulation occurs.

The heating system must always be completely embedded in:

• Concrete
• Asphalt
• Sand
• Thick mortar beds

Outdoor patio applications may require special installation methods and control systems.

For best performance, install ProMelt systems in concrete or mortar slabs with appropriate finish coverings.

Do not install directly in loose sand or similar materials, as poor heat conductivity may reduce system performance and shorten cable life.

STEP 1.2

Measure the installation area and create a layout drawing.

Remove any areas where ProMelt cannot be installed and plan around all obstructions.

Follow these installation guidelines:

• The base beneath the mat/cable should generally be a minimum of 2 inches thick using concrete, asphalt, or similar masonry materials.
• The heating mat/cable must be covered by a minimum of 1-1/2 inches of material.
• For elevated slab or deck-style applications, maintain at least 1 inch of masonry below and above the heating cable.
• Do not install heating cable within 6 inches of slab edges.
• For asphalt applications without curbs, maintain at least 12 inches from exposed edges.
• Avoid crossing expansion joints unless proper protection methods are used.
• Maintain at least 2 inches clearance from underground pipes, electrical wiring, or similar materials.
• Maintain cable spacing between 2 inches and 4 inches apart.
• Do not install beneath support columns, walls, mounting brackets, hand rails, light posts, or similar obstructions that may trap heat or damage the system.

STEP 1.3

Determine junction box locations.

Plan junction box locations carefully to ensure proper power lead routing and efficient layout of mats and cables.

IMPORTANT: The heating cable cannot be cut or shortened.

Select the correct mat or cable size for the installation area.

Modifying the heating cable may result in overheating, fire hazards, or permanent damage.

The heating cable and all factory splices must be completely embedded in concrete, asphalt, or sand.

Never install excess heating cable in surrounding soil, walls, or unprotected areas.

Do not overlap heating cable or place heating cable closer than 2 inches from adjacent heating cable.

Only the cold lead power wiring may exit the heated area through conduit.

Never pull heating cable or factory splices into conduit.

Indoor wall-mounted junction boxes are recommended whenever possible.

Standard ProMelt systems include approximately 20-foot power leads.

If outdoor junction boxes are required, they must be properly rated for wet-location outdoor use.

ProMelt systems cannot be installed:

• Indoors
• In industrial hazardous locations
• For gutter or pipe freeze protection
• For roof snow melting applications
• On or under wood or composite stairs and decks
• Around swimming pools or in-ground hot tubs unless approved by local code

STEP 1.4 - ProMelt Mat Selection

Wattage Selection

Select the heat output based on climate conditions and expected snow melting performance.

• 50 Watts per Sq. Ft. is recommended for moderate to heavy snowfall conditions.
• 38 Watts per Sq. Ft. is recommended for light to moderate snowfall conditions.

Mat Size Selection

ProMelt Mats are available in multiple sizes and configurations.

If the exact mat size is unavailable, select the next smaller size rather than attempting to modify the heating cable.

Electrical Load Requirements

Carefully verify voltage, amperage, breaker sizing, and control capacity before installation.

All electrical components should be designed to handle at least 125% of the heating system load.

Recommended Circuit Sizing

• 20 amp circuit for load up to 16 amps
• 30 amp circuit for load up to 24 amps
• 40 amp circuit for load up to 32 amps

  Recommended for light to moderate snowfall conditions and milder climates.

Cable Size Selection

Select the ProMelt Cable size that best fits the heated area measured earlier in the design process.

If the exact cable size is not available, select the next smaller size.

The heating cable cannot be cut or shortened.

Electrical Load Requirements

Carefully verify breaker sizing, amperage requirements, voltage compatibility, and electrical capacity before installation.

All circuit protection and wiring should be designed to handle at least 125% of the heating cable load.

Recommended Circuit Sizing

• 20 amp circuit for load up to 16 amps
• 30 amp circuit for load up to 24 amps
• 40 amp circuit for load up to 32 amps

240V and 277V ProMelt Cable Specifications

The following ProMelt snow melting cable specifications include coverage area, cable length, amperage, resistance range, and wattage information for 240V and 277V systems.

Recommended ProMelt Controls & Sensors

ProMelt Smart Panel Specifications

STEP 1.7

Consult with a qualified electrician to verify that the selected ProMelt Mats, ProMelt Cables, controls, and overall system design are compatible with the available electrical service and local code requirements.

The ProMelt snow melting system must be connected to a dedicated power supply from the circuit breaker panel.

ProMelt Mats and Cables are resistance heating systems and should be treated as continuous electrical loads for branch circuit sizing purposes.

The circuit breaker must disconnect all ungrounded conductors simultaneously.

A GFEP (Ground Fault Equipment Protection) device is required to directly protect the ProMelt heating system.

Recommended Circuit Sizing

• 20 amp circuit for load up to 16 amps
• 30 amp circuit for load up to 24 amps
• 40 amp circuit for load up to 32 amps
• 50 amp circuit for load up to 40 amps
• 70 amp circuit for load up to 50 amps

All circuit breakers and wiring should be designed to handle at least 125% of the heating system load.

Important Installation Note:

Do not install insulation beneath snow melting systems in areas exposed to vehicular traffic.

Compression of insulation over time may cause slab cracking and possible damage to the heating system.

All branch circuit wiring, conduit, and junction box installations must comply with NEC, CEC, and all applicable local electrical codes.

Outdoor and underground conduit systems and junction boxes must meet all required rain-tight or watertight installation standards.

Phase 2 - Preparations

Before installing the ProMelt snow melting system, carefully inspect all materials and review the installation layout.

The installation sequence may vary depending on site conditions, contractor scheduling, and electrical requirements.

Careful planning between the contractor, electrician, and installer will help reduce installation errors and avoid damage to the heating system.

Inspect the ProMelt Mat/Cable, Controls, and Sensors

STEP 2.1

Do not attempt to install damaged products.

Remove the ProMelt Mats, ProMelt Cables, controls, and sensors from their packaging.

Inspect all components carefully for visible damage and verify that the product sizes, voltages, and quantities match the installation plan and order specifications.

STEP 2.2

Do not remove the factory nameplate label.

The electrical inspector may need to verify this information during inspection.

Record the product model number, serial number, voltage, and resistance range for future reference and warranty purposes.

This information is located on the nameplate label attached to the power leads.

Provide a copy of this information to the property owner and keep it in a safe location.

STEP 2.3

Use a digital multimeter to measure the resistance between the conductors of the heating mat or cable power leads.

Record all resistance readings before installation.

The resistance measured between the white lead wires should fall within the resistance range listed on the product nameplate label.

Slightly lower readings may occur because of low ambient temperatures or meter calibration differences.

If readings appear incorrect or inconsistent, consult a qualified electrician or contact the manufacturer before proceeding.

Important Operating Notice:

Do not operate the ProMelt system in ambient temperatures above 68°F (20°C), except for a brief system test.

Snow melting performance depends on many environmental conditions including:

• Air temperature
• Ground temperature
• Wind conditions
• Solar heat exposure
• Moisture and snowfall levels

Heating performance may vary depending on the installation environment.

Measure resistance between the white lead wires and the ground lead.

The meter should indicate an open circuit, typically displayed as “OL” on most digital multimeters.

If any resistance is detected between the conductors and ground, stop installation and contact the manufacturer before proceeding.

Fluctuating readings may be caused by poor meter lead contact or damaged test leads.

STEP 2.4

An insulation resistance test should be performed by a qualified electrician using a megohmmeter (Megger® or equivalent).

The megohmmeter should be set to a minimum of 1000 VDC.

The measured insulation resistance value should be at least 20 megohms (MΩ).

Do not apply more than 1500 VDC during testing.

Megohmmeter Safety Notice

Megohmmeters apply high voltage during insulation resistance testing and may cause electric shock or serious injury if improperly used.

Always follow the megohmmeter manufacturer’s instructions and safety guidelines.

Base Material Preparation

STEP 2.5

Prepare the installation area before installing the ProMelt Mat or Cable.

Verify that all underground utilities, obstructions, drains, and structural elements have been identified before installation begins.

STEP 2.6 - General Site Preparation

The installation base must be smooth, solid, well-compacted, and structurally stable.

If installing over an existing slab, inspect the surface for sharp edges, loose debris, or any condition that may damage the heating cable.

Ensure proper drainage and slope to prevent standing water or ice buildup in heated and surrounding areas.

This is especially important for brick paver and sand-set installations where moisture may refreeze and cause movement or surface damage.

Follow all local building codes and construction guidelines regarding slab thickness, grade preparation, and drainage requirements.

Verify that the slab depth allows the heating cable to remain fully embedded at the correct distance below the finished surface.

The heating cable must always be completely embedded.

STEP 2.7 - Concrete Applications

For new concrete pours, install reinforcement such as wire mesh or rebar at the proper depth below the finished surface.

Use reinforcement chairs or approved supports to maintain the correct reinforcement height.

The ProMelt heating cable or mat will later be secured to this reinforcement.

It is critical that the heating cable remains fully embedded within the concrete slab.

Protect or remove all sharp protrusions.

Sharp edges or exposed reinforcement may damage the heating cable.

Bend, cap, trim, or otherwise protect any sharp materials before installing the heating system.

STEP 2.8 - Asphalt Applications

Install and compact the initial asphalt base layer over the prepared gravel foundation.

The ProMelt heating cable or mat will later be secured on top of this first asphalt layer.

Allow the asphalt surface to cool sufficiently before installing the heating system.

STEP 2.9 - Paver or Stone Applications

Follow all installation guidelines provided by the paver or stone manufacturer.

If sand-set pavers are being installed, first apply approximately 3/8 inch to 1/2 inch of sand over the base material to help protect the heating cable or mat from damage.

Important: For outdoor snow melting applications, ProMelt Mats and Cables should not be installed directly in loose sand or similar materials.

The heating system must first be embedded within a concrete slab prepared according to the concrete application guidelines.

Pavers or stone may then be installed over the slab using sand or mortar.

STEP 2.10 - Ceramic or Stone Tile Applications

ProMelt Mats and Cables may be installed directly within a structural concrete slab or inside a thick mortar bed above the structural slab.

In either application, the base preparation should follow the concrete installation guidelines described previously.

Electrical Preparation

STEP 2.11

Install all junction boxes in the locations determined during the system design phase.

STEP 2.12

Install conduit and branch circuit wiring from the electrical panel to the control location and from the control location to the junction boxes.

Follow all local electrical codes regarding wire sizing, conduit requirements, and installation procedures.

STEP 2.13

Install conduit from the junction box to the edge of the heated slab area.

Extend the conduit approximately 2 to 6 inches into the slab edge and install a protective bushing to help prevent damage to the heating cable power leads.

Follow local code requirements for conduit burial depth.

Plan conduit routing carefully when installing edge pavers, drainage systems, landscaping, or similar features

STEP 2.14

If an in-slab or surface-mount sensor will be installed within the heated area, install conduit from the control location to the planned sensor location.

For asphalt installations using a surface-mount sensor, the sensor housing must be embedded within a 12" x 12" concrete pad.

Follow all sensor manufacturer instructions for proper placement, wiring, and installation procedures.

STEP 2.15

Install the circuit breaker size and type determined previously during system design.

Do not connect the branch circuit wiring to the breaker at this time.

STEP 2.16

Label the electrical circuit breaker supplying the ProMelt snow melting system.

Use identification such as:

• Snow Melt
• Snow Melting System
• ProMelt Heating System

Phase 3 - Installation of Mat and/or Cable

The following Steps 3.1 through 3.12 cover standard ProMelt installation procedures.

Steps 3.13 through 3.14 cover special installation applications and additional requirements.

Basic Installation

STEP 3.1

Schedule installation at a time when heavy equipment, construction traffic, and job site activity will be minimal.

This helps reduce the risk of damaging the ProMelt heating system during installation.

Whenever possible, install the final surface layer over the heating system the same day to help protect the cables from damage.

Important Installation Guidelines:

• ProMelt heating cable cannot be cut or shortened.
• Do not overlap or cross heating cable over itself.
• Maintain at least 2 inches spacing between heating cables.
• The heating cable and factory splice connections must remain fully embedded within concrete, asphalt, sand, or approved mortar materials.
• Do not install excess heating cable in surrounding soil, walls, or unprotected areas.
• The factory splice and heating cable must never be installed inside conduit.

STEP 3.2

Test-fit the ProMelt Mat or Cable within the heated area before securing it permanently.

For ProMelt Mats:

Unroll the mat completely and shape it as necessary by carefully cutting only the mesh tape.

For ProMelt Cables:

Lay out the cable according to the planned spacing and verify that the cable length properly fits the installation area.

Installation Spacing Requirements:

• Do not install mats or cables closer than 6 inches from slab edges.
• For asphalt applications without curbs, maintain at least 12 inches from exposed edges.
• Avoid crossing expansion joints whenever possible.
• Maintain at least 2 inches clearance from underground utilities, piping, or other heating cables.

If installing the heating system within the upper layer of a two-stage concrete or asphalt installation, the heating system should be fully prepared before placement of the final layer.

There is limited working time between layers because the first layer should not fully cure or completely cool before the second layer is applied.

For ProMelt Cable installations, pre-tying the cable to reinforcement mesh may help speed installation during the second-stage pour.

Pre-cut and pre-shaped ProMelt Mats may also simplify installation during staged pours.

If a slab sensor will be installed within the upper layer, plan installation carefully to avoid excessive curing or cooling delays between layers.

Inspect the installation area carefully and remove any sharp objects or debris before securing the heating system.

STEP 3.2

Begin by test-fitting the ProMelt Mat or Cable within the heated area before securing it permanently.

For ProMelt Mats:

Completely unroll the mat and position it within the installation area.

The mat may be turned or flipped by carefully cutting the mesh tape where necessary.

For ProMelt Cables:

Lay out the heating cable according to the planned spacing and verify that the cable fits the area correctly without excess cable remaining.

Installation Requirements:

• Do not install mats or cables closer than 6 inches from slab edges.
• For asphalt applications without curbs, maintain at least 12 inches from exposed edges.
• Avoid crossing expansion joints unless proper protection methods are used.
• The heating cable cannot be cut or shortened.
• Do not overlap or cross heating cable over itself.
• Maintain a minimum spacing of 2 inches between heating cables.
• The heating cable and factory splices must remain completely embedded in concrete, sand, asphalt, or approved mortar materials.
• Do not install excess heating cable in soil, walls, or unprotected areas.
• Factory splices and heating cable must never be installed inside conduit.
• Maintain at least 2 inches clearance from underground pipes, utilities, and similar materials.
• Maintain spacing between adjacent mats or cable runs between 2 inches and 4 inches.
• Do not repeatedly bend the heating cable or sharply bend factory splices.

STEP 3.3

Position the power leads near the conduit entry location.

The electrician will later pull the power leads through the conduit during final electrical connection.

Verify that the factory splice connection and heating cable remain outside of the conduit at all times.

STEP 3.4 - Concrete Applications

ProMelt Mat Installation

Secure the heating mat to reinforcement mesh or rebar approximately every 2 feet using plastic cable ties.

Trim or position cable tie ends downward so they will not protrude through the finished surface.

Do not use metal ties, as they may damage the heating cable.

If installing over an existing slab, secure the mat by fastening through the tape approximately every 2 feet.

Never strike the heating cable with a hammer.

ProMelt Cable Installation

Secure the heating cable to reinforcement mesh or rebar using plastic cable ties at the end of each run and approximately every 3 to 4 feet.

If installing over an existing slab, secure CableStrap to the slab surface using nails or similar fasteners every 6 to 10 inches.

Additional CableStrap sections should be installed every 3 to 4 feet to help maintain cable spacing during concrete placement.

STEP 3.5 - Asphalt Applications

ProMelt Mat Installation

Lay the heating mat flat over the first asphalt layer and secure it using nails, staples, or similar fasteners through the mat tape approximately every 2 feet.

Do not place metallic nails or staples directly over the heating cable.

Use caution to avoid damaging the heating cable during installation.

STEP 3.6 - Stone or Paver Applications

ProMelt Mat Installation

Lay out the heating mat and secure it using landscape fabric stakes or similar non-metallic fasteners approximately every 2 feet.

Do not place metallic stakes or staples directly over the heating cable.

ProMelt Cable Installation

Secure plastic mounting cable ties to the gravel base using long nails or similar fasteners through the cable tie head.

Install cable ties at the end of each run and approximately every 3 to 4 feet.

Do not use metallic cable ties.

Lay out the heating cable and secure it using the installed cable ties.

STEP 3.7 - Ceramic or Stone Tile Applications

Thin-Set Mortar Applications

For thin-set applications, the heating mat or cable should be installed within the structural concrete slab approximately 1.5 inches to 2 inches below the finished surface.

Follow the concrete installation guidelines described previously.

Thick-Set Mortar Applications

For thick-set mortar applications, the heating cable should be installed within a mortar bed at least 1.25 inches thick above the structural slab.

Never strike the heating cable with a hammer.

ProMelt Mat Installation

Secure the mat to the slab surface using nails, staples, or similar fasteners through the mat tape approximately every 2 feet.

A minimum 1.25 inch mortar bed should cover the heating cable.

ProMelt Cable Installation

Secure CableStrap to the slab surface using nails spaced every 6 to 10 inches.

Additional CableStrap sections should be installed every 3 to 4 feet to hold the cable in place during mortar installation.

A minimum 1.25 inch mortar bed should cover the heating cable.

STEP 3.8 - ProMelt Mat Only

Do not kink or sharply bend the heating cable.

Maintain a minimum bend radius of 1 inch.

When turning or shaping the mat, carefully cut only the mesh tape using scissors.

Never cut the heating cable.

Maintain approximately 3 inches spacing between heating cables and never reduce spacing below 2 inches.

ProMelt Mat Turning Techniques

The following installation methods may be used when shaping ProMelt Mats to fit the installation area:

• Roll-Over Turn
• 90° Flip Turn
• 180° Back-to-Back Turn
• Fill-In Technique for irregular areas

When turning or reshaping the mat, carefully cut only the mesh tape.

Never cut, shorten, or damage the heating cable.

Maintain proper cable spacing during all turns and adjustments.

STEP 3.9

Use a digital multimeter to measure the resistance between the conductors and ground wire of the heating mat or cable power leads again.

Record these readings after the heating system has been secured in place.

STEP 3.10

Feed the power leads through the conduit into the junction box, leaving at least 6 inches of free lead length for electrical connections.

Secure the heating cable and factory splice to ensure they cannot be accidentally pulled into the conduit.

Apply electrical conduit sealant around the power leads at the conduit opening to help prevent water intrusion.

STEP 3.11

If installing a surface-mount sensor, position the sensor socket according to the manufacturer’s instructions.

The sensor should be located midway between heating cable runs and positioned in a representative heated area.

Secure and seal the sensor conduit connection properly.

Ensure the top of the sensor remains flush with the finished surface layer.

Protect the sensor opening using an approved cap or seal during installation.

STEP 3.12

Take photographs of the completed heating mat or cable layout before covering the system.

Installation photos can be extremely helpful for future repairs, renovations, utility work, or site modifications.

Keep all installation photos with this installation manual for future reference.

Special Applications

STEP 3.13 - Stair Applications

When installing ProMelt Mats on stairs, carefully cut only the mesh tape to allow the mat to conform to stair treads and risers.

For ProMelt Cable installations, secure a single cable run along the riser and install 3 to 4 cable runs across the stair tread as needed.

Follow these stair installation guidelines:

• Install heating cable no more than 3 inches from the front edge of the finished tread to help ensure proper snow melting coverage.
• Maintain at least 6 inches clearance from the side edges of the finished stair tread.
• Plan for future handrail installations and avoid placing heating cable in areas where mounting anchors may later be installed.
• Mark safe drilling locations on installation drawings whenever possible.
• Do not pinch, sharply bend, or kink the heating cable.
• Maintain a minimum 1 inch bend radius at stair tread and riser corners.
• Secure the cable flat enough to avoid pinching during concrete, mortar, or paver installation.

Do not install ProMelt Mats or Cables on or beneath non-masonry stairs such as wood or composite construction.

STEP 3.14 - Expansion Joints

ProMelt heating cable should never be installed directly through expansion joints.

Slab movement at expansion joints may damage the heating cable.

Whenever possible, position the heating mats or cables to completely avoid expansion joints.

If crossing an expansion joint is unavoidable, a loop of heating cable may be routed beneath the expansion joint within the base material below the slab.

The cable loop should be surrounded by at least 1 inch of sand to help protect the cable and allow movement flexibility.

The heating cable loop must remain free to flex with slab movement and should not be embedded directly within concrete at the expansion joint area.

Phase 4 - Finish Surfaces

STEP 4.1

Before applying the finish surface, inspect the ProMelt Mat or Cable for any visible damage and re-secure any loose sections.

Before covering the heating system, perform the following electrical tests again to verify system integrity:

• Measure resistance between heating conductors using a digital multimeter.
• Verify there is no continuity between conductors and ground.
• If possible, have a qualified electrician perform an insulation resistance test using a megohmmeter.

A megohmmeter adjusted to a minimum of 1000 VDC should measure at least 20 megohms (MΩ).

Do not apply more than 1500 VDC during testing.

Install Identification Marker Plates

Install a marker plate or other permanent identification showing that a ProMelt snow melting system is embedded within the slab.

This helps prevent accidental damage during future repairs, drilling, excavation, or remodeling work.

Marker plates should remain clearly visible and flush with the finished surface.

Use caution to avoid damaging the heating cable during marker installation.

STEP 4.2 - Concrete Applications

Pour concrete over the ProMelt heating system so that the heating cable is covered by no less than 1-1/2 inches and no more than 3 inches of concrete.

The total concrete slab thickness should be at least 4 inches.

Driveway installations may require greater slab thickness depending on local code requirements and expected vehicle loads.

Use caution during concrete placement.

Do not use sharp tools that may damage the heating cable.

Blunted shovels and careful concrete placement techniques are recommended.

Ensure the heating cable is fully embedded within the concrete.

Also fully embed the conduit extensions surrounding the power leads and slab sensor wiring.

Allow the concrete to cure completely according to the concrete manufacturer’s recommendations.

Do not energize the ProMelt system during the curing process, except for brief electrical testing.

Premature heating may accelerate curing improperly and potentially damage the concrete slab.

STEP 4.3 - Asphalt Applications

If required, apply a prime coat over the base layer before placing the final asphalt layer.

Use asphalt aggregate no larger than 1/2 inch to reduce the risk of cable damage.

Before installation, verify asphalt temperature does not exceed 285°F (140°C).

Apply asphalt so that the heating cable is covered by no less than 1-1/2 inches and no more than 3 inches of asphalt.

Do not use asphalt paving machines directly over the heating cable.

Manually place asphalt in the cable installation area.

Compact the asphalt using a small roller or compactor.

Avoid using large rollers that may force aggregate into the heating cable.

If possible, move the roller perpendicular to the cable direction to reduce stress on the heating system.

Avoid stopping or starting the roller directly above heating cables, as shifting asphalt may damage the system.

Ensure the heating cable and conduit extensions are completely embedded within the asphalt surface.

Do not energize the ProMelt system until the asphalt has fully cooled and cured according to manufacturer recommendations.

---

STEP 4.4 - Stone or Paver Applications

For applications that are not intended for outdoor snow melting, ProMelt heating cables may be embedded directly in sand.

Spread sand manually over the heating cable and base material so that at least 1-1/2 inches of sand covers the top of the heating cable.

Do not install ProMelt Mats or Cables directly in sand for outdoor snow melting applications.

Outdoor snow melting systems must first be embedded within a concrete slab.

Use caution during installation and avoid sharp tools that could damage the heating cable.

Compact the sand according to the paver manufacturer’s recommendations while ensuring the heating cable remains fully covered.

Use hand compaction tools carefully around conduit areas to avoid damaging power lead or sensor conduits.

Add additional sand if necessary to maintain the minimum required coverage depth.

Ensure the heating cable and all conduit extensions remain fully embedded.

After preparation is complete, install the pavers or stone finish surface according to manufacturer guidelines.

Important Performance Note:

The greater the thermal mass above the heating cable, the longer the system may take to respond during cold-start snow melting conditions.

Slab or mortar thicknesses exceeding 4 inches may significantly increase response times and may require specialized control strategies.

---

STEP 4.5 - Ceramic or Stone Tile Applications

Use only exterior-rated installation materials and follow all tile manufacturer installation guidelines.

Only vitreous (non-porous) tile should be used for exterior heated applications.

Porous tile materials may absorb moisture and lead to freeze-related damage.

The finished material thickness above the heating cable should be:

• No less than 1.5 inches
• No greater than 2.5 inches

A movement joint should always be installed between heated and non-heated areas.

Thin-Set Mortar Applications

In thin-set applications, the heating system is already embedded within the structural concrete slab.

The mortar bond coat and tile should be installed according to Tile Council of North America (TCNA) exterior application guidelines and ANSI standards.

All mortar and grout materials should be rated for exterior installations.

Thick-Set Mortar Applications

For thick-set mortar installations, the ProMelt Mat or Cable is installed above the structural slab within a thick mortar bed.

A minimum 1.25 inch mortar bed should cover the heating system according to ANSI A108.1A guidelines.

The mortar bond coat and tile finish surface are then installed above this layer.

STEP 4.6

After all finish surfaces have been installed, use a digital multimeter to measure the resistance between the heating conductors again.

Record the final resistance readings after the finished surface installation is complete.

Phase 5 - Controls and Sensors

Refer to the appropriate ProMelt wiring diagrams and control installation instructions before completing electrical connections.

STEP 5.1

De-energize all electrical circuits supplying the ProMelt system before performing any electrical work.

STEP 5.2

If installing a surface-mount sensor, remove the protective cap or seal from the embedded sensor socket.

Feed the sensor wires through the conduit to the control location.

Secure the sensor in place and complete installation according to the sensor manufacturer’s instructions.

STEP 5.3

Complete all electrical connections between the ProMelt heating system power leads and the power wiring from the control panel within the junction boxes.

If junction boxes are installed outdoors, use wet-location rated wire connectors or crimp connectors to help prevent corrosion and moisture-related failures.

STEP 5.4

Install the snow melting control according to the manufacturer’s installation instructions.

Complete all required electrical connections to:

• Power supply wiring
• Sensor wiring
• Heating mat or cable power leads

Verify all wiring connections and electrical protection devices before energizing the system.

The ground wire supplied with the ProMelt Mat or Cable must be connected to an approved grounding or earthing terminal according to local electrical code requirements.

STEP 5.5

After carefully inspecting all wiring connections, connect the system power supply wiring to the GFEP circuit breaker and energize the system.

STEP 5.6

Follow the control manufacturer’s instructions to complete system setup and programming.

The snow melting control and sensor system should only energize the ProMelt heating system when the proper snow melting conditions are detected.

Most controls allow a temporary system test mode for initial verification.

If available, use a clamp-on electrical meter to verify that the ProMelt system is drawing the expected amperage during testing.

Do not fully energize the ProMelt system until all concrete, mortar, or asphalt materials are fully cured and cooled.

Operating the heating system too early may damage surface materials or cause improper curing.

Do not operate the ProMelt system when ambient air temperatures exceed 68°F (20°C), except for short testing periods.

Extended operation in high temperatures may reduce heating cable life and potentially damage surrounding materials.
