Installing multiple undertile heating cables
When installing two or more cables, begin by reading the sizing guide on page 18 of
this booklet to ensure ou have the proper number and size of cables for the area
you wish to heat. The sizing guide will also tell you the perimeter and heating cable
spacing required for your particular room size.
After you prime the subfloor, mark the subfloor as per the instructions on page 17 and
lay the first cable. Do not cover the first cable with tape at this point as you may wish to
slightly alter the spacings later on. Lay the second cable in the remaining area using the
same perimeter and heating cable spacings as the first cable and test the second cable.
When laying more than one cable, it is important to keep these points in mind:
1. The heating cables
may not touch
or cross at any point.
2. The heating cables are joined in parallel only at the Thermostat.
Do not attach one
cable to another in series.
3. The heating cable spacings for all cables in an area should be approximately
equal
.
