Floor Coverings - Hardwood Flooring
STEP 1:
Fix the wood sleepers (strips of wood 1” x 1” to 2” x 3/8” to ½”) perpendicular to the planned
direction of hardwood board with 21” center.
On the plywood subfloor, leave a sufficient space at the end of each wooden sleeper to allow
the cable to go through from one section to the other.
The sleepers are fixed in such a manner that they create a required gap between two sleepers
in which the Warmup mat can be installed. Cut approx ½ out of the sleeper, whenever the
cable is to be carried over to the next sleeper bay.
STEP 2: NADWM System Installation:
Now Install the mat into the gap which was created by the sleepers.
NOTE: Sections of the cable will need to be removed from the mesh so that the cable maybe
carried over to the next sleeper bay. Be careful not to damage or cut the cable when taking it
across the sleepers.
Carefully return the cold tail lead to the power supply alongside the heating cable and wooden
sleepers, if required.
STEP 3: Install the floor sensor
Place the probe wire containing the capped sensor evenly between two heating cables at least
12” (30.48cm) from the wall into the heated area. At no time should the probe wire cross the
heating cable.
STEP 4: Covering of the NADWM system
Once the heating mats have been laid, the system should be covered by self-leveling compound,
or dry-pack up to sleeper’s height. Do Not cover the sleepers.
STEP 4: Hardwood Flooring Installation:
Once the leveling compound or dry-pack has cured, the hardwood flooring may be installed by
nailing it into the wooden sleepers. Be careful not to place nails or staples near to the heating
cable or power lead.
