Design and Installation
STEP 2 PLAN THE LAYOUT
Draw a sketch of the floor plan of the room where Cozy Heat® is to be installed. Include furnishings and fixtures, such as
toilets, bathtubs, appliances, cabinetry etc. The sketch should show all measurements and dimensions in order to deter-
mine the floor area available for floor warming. Determine the location for the Cozy Heat® thermostat and floor sensor.
Note: 120 and 208/240/277 thermostats must be located at least
4 feet away from shower or bathtub openings so that it cannot be
exposed to water, and so that persons in the shower or bathtub
area cannot make contact with the thermostat.
Using a chalk line or carpenter’s pencil, draw an outline of the floor area to be heated directly on the sub floor, including
permanently installed and uninstalled furnishings/fixtures.
Using your floor plan sketch, determine the desired appropriate spacing of Cozy Heat® Heating Element. Heatizon
Systems recommends 3” to 9” spacing as required to satisfy the heat loss calculation for spacing and 8 to 15 watts per
square foot for floor warming, see an authorized Heatizon Systems distributor for more details. Note that the minimum
distance between the cables cannot be less than 1 inch. Using a chalk line, mark the desired location where each run of
Cozy Heat® Heating Element will be installed using the predetermined appropriate spacing for the Cozy Heat® Heating
Element. Once the Cozy Heat® Heating Element locations are satisfactorily marked, the chalk lines can be covered with a
clear spray lacquer.
Establish the location of the connection point between the Cold Lead and the Cozy Heat® Heating Element. Remember,
The transition joint between Cozy Heat® SR Heating Element and the cold lead must be embedded in asphalt, concrete,
sand, stone, other cementitious material, or be in a junction box.
STEP 3 TRANSFER TO THE FLOOR
Ensure that the subfloor is flat and securely anchored to prevent it from moving and damaging the Cozy Heat® Heating
Element and floor covering. Carefully fill in all gaps in the securely anchored subfloor.
Clean the subfloor thoroughly, removing dust, miscellaneous debris and all other materials from the subfloor that may dam-
age the Cozy Heat® Heating Element. Eliminate protruding nails, staples, or any other objects that may damage the Cozy
Heat® Heating Element prior to installation.
