Installation and Operation SECTION 5
5.5.6 Instructions for Installation Under Hardwood Flooring
Note : Although TempZone™ Floor Heating Cable (Twin) is approved for direct contact with combustible material,
WarmlyYours strongly recommends that the cable be embedded in thinset, self-leveling underlayment, cement-
based adhesive glue, or tile adhesive under wood flooring surfaces.
STEP 1: Install wood sleepers
Using nails, adhesive, or other acceptable means of attachment, install wood sleepers
(strips of wood 1 to 2 inches wide and 3/8 to 1/2 inch high) at intervals 19 inches
apart, or distance specified by the flooring manufacturer, perpendicular to the planned
direction of hardwood boards.
The plywood subfloor must leave appropriate spacing and gaps for any planned runs
of cable to other heated areas. The sleepers are fixed in such a manner that they create
a required gap between two sleepers in which the warming system can be installed.
STEP 2: Install the floor warming system
Install Cable Fixing Strips as described in section 5.5.1. Using the Cable Fixing Strips to
secure the cable, install the floor warming system into the gap created by the sleepers.
Carefully return the power leads to the power supply alongside the warming system
and wood sleepers. Attach PowerMan™ and Circuit Check™ to the cold leads at this
time. Refer to section 5.3 for PowerMan™ instructions and section 5.4 for Circuit
Check™ instructions.
STEP 3: Cover the floor warming system with self-leveling compound
After the warming system has been put in place, it should be covered with self-leveling
compound up to the height of the sleepers. Do not cover the sleepers. The tops of the
sleepers should remain uncovered and visible.
STEP 4: Install hardwood flooring
Allow the appropriate time for the self-leveling compound to completely dry and cure.
After the compound has dried and cured, install the hardwood flooring. The hardwood
floor can be installed by nailing it to the wood sleepers. Be careful not to place nails or
staples near the system’s heating cable or power lead.
