Install Instructions

STEP 2.9
Paver or Stone Applications
Follow guidelines recommended by the paver manufacturer. If a coarse of sand is to be applied over the gravel base,
the mat/cable must first be secured in place and then covered with a minimum 1-1/2 inch layer of sand to completely
embed the mat.
STEP 2.10
Ceramic or Stone Tile Applications
ProMelt mats or cables can be installed in the structural slab or in a thick mortar bed above a structural slab. In either
case, the base material should be prepared according to section 2.7 Concrete Application.
ELECTRICAL
STEP 2.11
Install junction boxes in the location(s) planned during the design process Phase 1 (see Step 1.3).
STEP 2.12
Install conduit and branch circuit wiring from the circuit breaker panel to the control location, and from the control to
the junction boxes. Follow local code for wire size, conduit requirements, and proper installation procedure.
STEP 2.13
Install conduit from the junction box to the edge of the slab to be heated. Extend this conduit into the slab edge about
2 to 6 inches and attach a bushing to the end to prevent damaging the mat/cable power leads.
Follow electrical code for burial depth of the conduit.
•
Plan carefully if you are installing edge pavers, edge drainage systems, landscaping, or other items that affect •
where the conduit comes in.
STEP 2.14
If a slab sensor is to be embedded in the heated area, install conduit from the control location to the desired slab loca-
tion. Follow the sensor instructions for proper placement and connections.
STEP 2.15
Install the circuit breaker size and type as determined earlier in Step 1.7 (Designing the System). DO NOT connect the
branch wiring to the breaker yet.
STEP 2.16
Label the circuit breaker in the panel which feeds this Snow Melt mat system with “Snow Melt” or similar.
Phase 3: Installation of Mat and/or Cable
The following Steps 3.1 through 3.12 cover installation basics. Steps 3.13 through 3.14 cover some specific applications
and their special requirements.
BASIC INSTALLATION
STEP 3.1
Determine a time to install the mat/cable when equipment,
heavy tools, and site traffic will be minimal to keep from possibly
damaging the product. Be prepared to apply the surfacing courses
over the mat/cable the same day so it will be protected from
damage.
If installing mat/cable in the upper layer of a two-stage concrete
slab or the upper layer of an asphalt application, the mat or cable
should be completely ready for the second stage. There is limited
time between stages, as the slab should not be allowed to fully cure
