6. Frequently asked questions (FAQ)
Q.1: Can we cut the OWC-M heating cable to reduce its length?
A.1: NEVER. When the OWC-M concrete cable mat is too long, spread the excess over the entire floor. To
achieve this, arrange the heating cable mat in regular loops while adhering to minimum distances, along wall
partitions and between parallel sections of the heating cable mat.
Q.2: What should be done before choosing the adequate OWC-M product?
A.2: Draw out a plan of the area to be covered. Follow steps 1 to 7 in paragraph 4.1 of the present manual or
send a copy of your construction plan by fax to 1 800 662-7801 or via e-mail to [email protected]. Make sure
you send a copy of the plan to scale as well as a list of all fixed elements which have to be bypassed. At the
very least, we will need a horizontal measure and a vertical measure to validate the scale. Our technical support
technicians will be pleased to provide you with a list of material and a layout sketch to guide you through your
installation.
Q.3: How do we repair the OWC-M cable in case of breakage?
A.3: First, (as a preventive method) from the very start, you should test the cable each time it is indicated in the
instruction book. As well, you should fill out the measurement chart (label supplied in the kit). However, in case
of breakage, if the concrete pouring process has not begun, contact Ouellet Canada Inc.’s technical support
services and ask for a repair kit (OWC-KIT). If the pouring process has begun, delineate an area at least 2 ft
2
(0.18 m 2 ) around the damaged cable and DO NOT cover that area with concrete. Once the concreting process
is complete, contact Ouellet Canada Inc.’s technical support services and ask for a repair kit (OWC-KIT).

Q.4: Are there different power levels available by square foot?
A.4: Ouellet Canada Inc. estimates that 11W/ft
2 (120W/m 2 ) with a spacing of 6’’ (15 cm) is an adequate value
which should not be exceeded in order to optimize your comfort level without creating any overheating hazard.
Furthermore, the power level per ft
2 (m 2 ) is identical for 240/208V and 347V cables.
Q.5: Can two heating cables cross, overlap or touch one another?
A.5: NEVER. This could create an overheating hazard. A minimum of 6” (15 cm) space must be maintained
between cable mats.
