plastic clips. Place clips over the cold lead and the heating cable at
the splice and SECURE them to the oor. ENSURE THAT STAPLES
DO NOT PENETRATE THE CABLE! (Figure 2a)

2.4 Install cable in the membrane
• Embed Heating Cable (White section) in membrane channels
according to Figure 2c. Use a roller to secure cable in place. Install
cable runs as follows:
Figure 2c. Secure cable
• Standard Spacing: Cables are spaced 3 channels apart according to
Figure 2d - this results in spacing of 3-3/4” (90mm) between cables
and provides 12 Watts/sq.ft.
Figure 2d. Standard cable spacing
• Alternate Spacing: Cables are spaced alternately 3 channels
apart and 2 channels apart according to Figure 2e - this results in
spacing of 3-3/4” (90mm) and 2-1/2” (60mm) between cables and
provides 14.5 Watts/sq.ft.
Figure 2e. Alternate cable spacing
• Dense Spacing: Cables are spaced 2 channels apart according to
Figure 2f - this results in spacing of 2-1/2” (60mm) between cables
and provides 18 Watts/sq.ft.

NOTE: HEATING CABLE MUST BE INSTALLED IN THE
MEMBERANE IN THE MANNER DESCRIBED. FAILURE TO DO
SO MAY RESULT IN IMPROPER SYSTEM OPERATION. If any
adjustment in the cable spacing is required, carefully pull out heating
cable and reposition. THE DISTANCE BETWEEN ADJACENT
CABLE RUNS MUST NOT BE LESS THAN 1 ½” (38 mm).
2.5 If “half of cable” marker does not meet at “half heated area”
• When you reach the “Half of Cable” marker, pause to evaluate the
remaining area. If the “Half of Cable” Marker appears BEFORE the
Half-of-Area-Line previously marked on the oor, there will likely be
a cable shortage at the planned end of run, the amount of which
depends on how far before the line the marker appears. For a cable
shortage, consider the low trafc areas and Border Dimension.
Cable can be conserved by avoiding placement in low trafc areas
or by increasing the border dimension. The border may be increased
to a maximum of 6”. To do this, carefully remove the cable from the
mat and increase the border dimensions, but no further than 6” (15
cm) from the wall; this will reduce cable usage. Re-install the cable
according to the method outlined in Step 2.4. Do NOT increase
cable spacing by more than 3-3/4” (90mm) as this will result in
a cold oor! Once the cable layout is complete, ensure all cable
runs are sufciently secured to prevent interference during mortar
trowelling.
• If the “Half of Cable” Marker appears AFTER the Half-of-
Heated-Area- Line previously marked on the oor, there will likely
be a cable surplus at the planned End of Run, the amount of which
depends on how far past the line the marker appears. Surplus
cable may be used up by routing it into Low Trafc Areas. You may
also reduce the cable spacing to 2-1/2” (60mm) between adjacent
runs. Both methods will help to consume the surplus cable. THE
DISTANCE BETWEEN ADJACENT CABLE RUNS MUST NOT BE
LESS THAN 1 ½” (38 mm).
2.6 Secure sensor wire, tail splice and any loose cable
• If a oor temperature sensor will be used, position the Sensor Wire
midway between two adjacent Heating Cable runs. The end of
the sensor wire should extend at least 6” (15 cm) from the Return
Loop and lay in the centre of spacing between two heating cables.
Embed the sensor wire in the membrane. After installing the cable
completely, follow step 2.3 to create housing for the tail splice and
secure the splice in place. (Figure 2b)
2.7 Verify resistance of heating cable & sensor wire
• Before proceeding with nal oor nishing, measure the resistance
of the Heating Cable and optional Sensor Wire to ensure that
no damage has occurred to either cable during installation. To
measure heating cable resistance, connect the ohm-meter leads to
the Cold Lead conductors. The resistance will be between 10 and
250 ohms. To measure sensor resistance, again connect the ohm
meter leads to the sensor wire conductors. The resistance will be
between 7 and 14 k-ohms. If the resistance of either cable does not
fall within the specied range, please contact Easy Heat toll free at
(800/537-4732) and DO NOT energize the heating cables. If each
resistance reading is within the specied range, you may be ready
to proceed with oor nishing. NOTE: Your system Installation may
require an electrical inspection at this time (prior to proceeding with
