WARM SURFACES™ INSTALLATION MANUAL VER 1.4

READ CAREFULLY BEFORE STARTING INSTALLATION

1. Verify your cable selection by measuring and determining the square footage of
the “heated area”. Do not include areas were cabinets, sinks, shower stalls or
closets may be installed.

Note: Since the heating cable cannot be cut and that it’s whole length has to be
covered by the base mortar. The selected cable should always cover an area equal
to or less than that of the heated area excluding the “BUFFER ZONE”. (The buffer
zone is an area of the room where heating can be modified without compromising
the total comfort of the room)
See FIGURE 1.

2. Tampering with the length of the cable (cutting the cable) will result in injury
and/or fire hazard thus voiding the warranty.

3. It is very important that once the layout of the floor heating cable is complete,
we suggest that a drawing or photo be made and kept in your records for future
reference.

4. WARM SURFACES™ floor heating system may be used as a primary source of
heat. Heat generated from the floor is in direct relation with the area of the heated
floor (12 watts /sq ft @ 3” spacing). You should carefully evaluate your heating
needs for your region. A separate source of heat may be needed.

Note: DO NOT pull the floor heating wire tight against the floor gauge, create a 3”
loop.

5. WARM SURFACES™ floor heating system is an “electrical appliance” and it
should be installed in accordance with local and national electrical codes. Qualified
personnel should supervise its installation.

LAYOUT PLAN

Before installing the cable, insure that all surfaces on which the heating cable will
lie are free from any sharp objects, i.e. nails, screws, staples, splinters, debris or
other restrictions that may cut or otherwise damage the heating cable.

Refer to HEATED AREA FIGURE 1 for layout details.

Carefully consider the location of the “buffer zone”, (buffer zone is an area of
the room where heating can be modified without compromising the total comfort
of the room) FIGURE 1. Allow sufficient space along walls and cabinets and
around floor drains, toilets and showers.

The heating cable must not overlap under any circumstance. Overlapping will
create a hot spot and will damage the cable.

BEFORE INSTALLATION

With a digital multimeter measure the resistance of the cable between the two
leads, (Black wire and Red wire or Black wire and White wire) see (FIGURE

2). The resistance of each cable should be within 2 percent of the value in Table

1).The measurement should agree with the value marked on the cold lead of the

cable. Record this value on the warranty page.( page 22 )
If the resistance does not match the resistance
Of the specific cable you have purchased, please
Contact your WARM SURFACES Representative

With a Megohmmeter measure the insulation resistance between the Black wire
and the Green wire. The insulation resistance must not be less than 1000
megohms. Record this value on the warranty page. (page 22 )

equipment is required.

Electrical shock may occur.

If you have measured less than 1000 megohms of resistance between the Black
and Green wires, Do not connect the cable, contact your WARM
SURFACES™ Representative.
