1. Concrete heating cable OWC-M Series
WARNING!
1.1 General information
The concrete heating cables, series OWC-M include plastic mats of heating cables combined with an electrical connection which can be connected to an electrical power source. This system is typically referred to as a series heating cables set in accordance with the Canadian Electrical Code.
Installation must meet requirements specified by the following codes, when applicable:
- Canadian Electrical Code (CSA C22.1)
- American National Electricity Code (ANSI/NFPA 70)
- Any additional national or local installation code
In order to avoid any risk of electrical shocks,
always make sure the power from the electrical supply
circuit is turned off before handling the cables.
1.2 Critical information
- The OWC-M product is a system intended to heat a building either as a back-up heating system for a specific room (floor control) or as the main heating system for a specific room (ambient control with floor limit).
Note: Installations using the OWC-M system for ambient control with floor limit only, see section 3.
- The OWC-M concrete heating cable system is designed and approved for interior heat (dry and humid environments) as per specifications from the Canadian Electrical Code.
- The OWC-M concrete heating cable system is not designed for snow clearance applications or any other exterior applications.
- The OWC-M concrete heating cable system can be installed under interior partitions, staircases, showers and other sanitary fixtures, if clearances from drains and other fixed obstacles (fixed in concrete) are adhered to and provided the system is used with a temperature sensor which regulates the temperature of the concrete slab (see the following section for clearance guidelines).
- Floor temperatures will vary depending on floor insulation and characteristics. Maximum temperatures for the floor and the room depend on various factors such as the type of insulation present in the room, the slab, the number of windows, type of floor covering selected, etc...
- The OWC-M concrete heating cable system must be completely encased in concrete.
- The OWC-M concrete heating cable system must be installed by a certified electrician who is familiar with the proper assessment of power strength requirements and risks associated with installation requirements, as well as the construction techniques required for the installation and usability characteristics of the OWC-M concrete heating cable systems.
- The OWC-M concrete heating cable system is but one step in the construction of a floor. Each building trade involved is responsible for its own contract stipulations and must ensure that the work performed immediately before their work segment begins has been completely and adequately finished, all according to good engi­neering practices. Everyone is a stakeholder in the installation process and the onus of responsibility rests equally on every individual.

1.2.1 Required clearances
The OWC-M concrete heating cable system is designed to generate 11 W/ft² (120 W/m²) of heat as per factory installed specifications, with spacings of 6” (15 cm). Any spacing other than those specified in the manual must first be approved by a specialist from Ouellet Canada Inc. OWC-M concrete heating cable systems must be installed according to the following minimum distances:
- 3’’ (7.5 cm) between mat strips.
- 6’’ (15 cm) from the exterior perimeter of walls in the room to be heated.
- 3’’ (7.5 cm) from interior walls (if installed in ambient control by room).
- 6’’ (15 cm) from any drain or other fixed obstacle to be bypassed.
- 8’’ (20 cm) from any heating appliance anchored into the floor or coming into contact with the floor (not applicable for convector-type appliances).
- 2’’ (5 cm) within the concrete surface.
- 0.5’’ (1.3 cm) from any open combustible surface.
1.2.2 Always
- Read the present instruction book in its entirety before installing the product.
- Install the OWC-M system together with an adequate and approved temperature control device.
- Use copper wires only.
- Perform tests required in accordance with the present instruction book and record findings on the measurement chart.
- Make sure heating cables are completely encased in concrete.
- Make sure supply voltage is equivalent to the system’s rated voltage.
- Perform any repair work using the OWC repair kit available at your authorized Ouellet Canada Inc. dealer.
- Consult Ouellet Canada’s specialists for any additional information.
- We recommend installing OWC-M systems in temperatures above 5 °C (40 °F).
- Metallic structures or materials used for supporting cables or on which cables are installed must be grounded in compliance with the Canadian Electrical Code (CSA C22.1, section 10 and the National Electrical Code).
- Installers must inspect and remove any damaged or defective heating cables before they are covered up.
- Installers must provide markings on circuit-breakers (labels) that supply the electric circuit for the heating cables.
1.2.3 Never
- Install OWC-M mat cable sections that are less than 3” (7.5 cm) from one another. This could create overheating of the floor and cause damage.
- Reduce the length of heating cables or alter OWC-M cables in any way throughout their entire surface;
- Cross, overlap or layer heating cables (cables should never touch).
- Connect a product designed for 208/240V to 347V.
- Subject concrete cables to a bend radius inferior to 1.5” (38 mm).
- Install the temperature control device (thermostat or other) in a location which is accessible from a shower or bathtub (the control device must be installed more than 1 meter away (3 feet, 4 inches)).
- Use metal fasteners for installing heating cables or the temperature sensor.
- Install the OWC-M heating cable system if the security seal has been broken.

2.2 Insulation tests
Using a megohmmeter, measure the insulation resistance of OWC-M products at each stage of the installation and note the values in the measurement chart on the electrical panel label available in the envelope provided with the product.
Dangerous test. For the warranty to be applicable,
you must fill the measurement chart and ensure that all
8 measurements have been correctly recorded.
The system’s insulation resistance must be determined by a certified electrician using the following method:
- With a calibrated megohmmeter only.
- Measure the insulation resistance at the loose end of the cold lead between the phase conductor and the grounding.
- Record the value measured in the measurement chart.
- The value must be superior to 1,000,000 ohms.
- If the value is inferior to 1,000,000 ohms, postpone the work and contact Ouellet Canada’s specialists at 1 800 463-7043.
