Layout Planning
At a 3 peg spacing the specific heat load of the DCM-PRO system
is ~ 13 W/. By adjusting the cable spacing, the installation
can be customized to suit both the floor coverage and heat load
requirements.
When installing the cable using the DCM-PRO membrane, maintain a
2 peg (2
3
/
8
”) perimeter spacing, between itself and the perimeter or
any unheated areas.
Primarily used in areas requiring a rapid heat-up time. The higher
heater power will not necessarily lead to more heat output, just a
faster heat-up.
This is the standard (UL-Approved minimum) spacing and works best
for most projects. It has enough excess power to heat-up quickly, but
uses less wire and is more economical.
3-4 or 4 peg spacings are primarily used in areas with lower heat-loss,
such as well-insulated homes (Passive Houses). With these lower
outputs, it is important to consider the flooring choice so as to reduce
the chance of striping (oen if the flooring is too thin).
Warmup NADCM-C cables are UL certified or listed to the
following standards and usage: (File: E303230)
• UL 1683 "Electric Heating Products For Installation Under Floor
Coverings".
• CAN/CSA-C22.2 No. 130-16 "Requirements for Electrical
Resistance Trace Heating and Heating Device Sets".
Where peg spacings of 3, 3-4 and 4 are used, the UL certification
applies to the entire system, including the membrane.
