10. ELECTRICAL REQUIREMENTS
The heater, when installed, must be electrically grounded in accordance with local codes or, in the
absence of local codes with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electri-
cal Code, CSA C22.1. All wiring and electrical connection must conform to the requirements of
the above codes.
Single heater requires 24 Vac, 60 Hz electrical transformer sized at 40 VA. If multiple heaters are
connected to a single transformer, the proper transformer is 24 Vac, 60 Hz, sized at 40 VA for the
first heater, plus 20 VA for each subsequent heaters. For example, four heaters wired together
(parallel), require a transformer of 100 VA. It is not recommended to install more than 12 heaters
per zone. PROPER WIRING POLARITY MUST BE MAINTAINED, particularly when grouping the
heaters in a zone.
Total wiring distances of up to 200' must use minimum 16 gauge electrical wire, and wiring dis-
tances of over 200' must use minimum 14 gauge electrical wire. The heater when installed must
be electrically grounded in accordance with the local codes or, in the absence of local codes, with
the National Electrical Code, ANSI/NFPA 70. Malfunction of the heating system will result if the
voltage varies by more than +10% or -10%.
The heater can be controlled by:
 The “on / off” switch located in the control cover on the heater
 An optional radio frequency hand-held remote control
 Power to the heater or zone of heaters can be controlled / isolated by a switch or switching
panel located in a secure central location
 Total load of all heaters must be considered in determining the required contact rating of
the controlling switch.
Keep any electrical supply cord or wiring away from any heated surfaces.
