STEP 1: Wooden Sleepers / Strips Installation:

Fix the wood sleepers (recommended 1" / 25 mm wide x 3/8" / 9.5 mm thick or similar) perpendicular to the planned direction of 

hardwood board. 
On the plywood subfloor leave a sufficient space at the end of each wooden sleeper to allow the cable to go from one section to the other. 
The sleepers are fixed in such a manner that they create a gap between 12-16" (30.5-40.6 cm) between two sleepers in which the 

STRATA_HEAT™ Wire can be installed. Cut a 1/2" (12.7 mm) groove into the sleeper to carry the cable from one gap to the next.

STEP 2: STRATA_HEAT™ Floor Heating System Installation:

Install the STRATA_HEAT Spacing Strips at both ends of the sleeper runs. For runs longer than 4ft (122 cm), install one or more fixing 

strips in between to secure the cable at least every 45-50” (114-127 cm). Run the STRATA_HEAT Wire parallel to the STRATA_HEAT 

Spacing Strips.
Now Install the STRATA_HEAT Wire into the gap which was created by the sleepers.
Carefully return the cold tail lead to the junction box or the STRATA_HEAT Thermostat alongside the STRATA_HEAT Wire and wooden 

sleepers, if required. 

STEP 3: Install the floor sensor 

Place the probe wire containing the capped sensor evenly between two STRATA_HEAT Wire loops at least 12" (305 mm) from the wall 

into the heated area. At no time should the probe wire cross the STRATA_HEAT Wire.

STEP 4: Covering of the STRATA_HEAT Floor Heating System 

Once the STRATA_HEAT Wire(s) have been laid, the system should be covered by self-leveling or dry-pack compound up to the 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 wood sleepers. Be careful not 

to place nails or staples near to the STRATA_HEAT Wire or power lead.
