Embedded Snow & Ice Melting System Installation Manual CM1010 - 04-08-13
Before Installing • Installation of this system must be made in accordance with National Electrical Code Article 426 - Fixed Outdoor Electric Deicing and Snow-Melting Equipment. • Install all wiring in accordance with all national and local codes pertaining to outside wiring. • For installation under concrete only. • Do not install this system under tarmac or other hot-pour surfacing materials. • Do not incorporate any other outdoor electrical equipment in any branch circuit which feeds this heating system.
Components • Calorique heating mats. Supplied by Calorique or authorized distributor. See the following section for specifications of heating mats. • Electrical control device. Supplied by Calorique, automatically turns the system on and off based on the temperature, humidity, and presence of precipitation. This unit is a doublepole line voltage unit that meets National Electrical code requirements. • Overcurrent Protection. User / installer supplied.

System Layout Figure 1. Heating elements wired in parallel. Layout the system based on the following: Residential Sidewalks and walkways • In most cases, one heating mat is all that is needed to melt snow and ice from the width of a standard residential sidewalk or walkway. Surface Material (optional) Figure 2. Cross section of system (sand base not shown). Concrete • More than one length of heating mat may be required to heat the entire length of the sidewalk or walkway.
Installation 1. Using an accurate ohm meter, test each element to ensure that it is within the limits shown on the specification sheet. 2. Grade area to be heated as normal. Remember to grade down an extra amount equal to the thickness of the insulating material used. 3. Lay insulation in those areas which will be heated. 4. Place heating mats on the insulation per the layout you prepared. • Push the supplied stakes through the grommets on the heating elements, into the sand or insulation base below.
. Confirm the resistance of the system by performing another ohm check with an accurate ohm meter and comparing it against the figures provided on the specification sheet. This check ensures that no damage has occurred to the elements during the installation process. 8. Make electrical connections between the heating mats and the branch circuit wiring per the layout you prepared, making sure to take into account all applicable electrical regulations.
