Standard units are shipped for use on 115 volt, 60 hertz 
single phase electric power. The motor nameplate and 
electrical rating of the transformer should be checked 
before energizing the duct furnace electrical system. All 
external wiring must conform to the latest edition of ANSI/
NFPA No. 70 National Electrical Code and applicable local 
codes; in Canada, to the Canadian Electrical Code, Part 1 
CSA Standard C22.1.

It is recommended that the electrical power supply to each 
duct furnace be provided by a separate, fused, and 
permanently live electrical circuit. A disconnect switch of 
suitable electrical rating for each duct furnace should be 
located as close to the gas valve and controls as possible. 
Each duct furnace must be electrically grounded in 
accordance with the latest edition of the National Electric 
Code, ANSI/NFPA No. 70 or CSA Standard C22.1.

Mount the thermostat approximately 5 feet (1.5 m) above 
the floor in an area where it will be exposed to a free 
circulation of average temperature air. Always refer to the 
thermostat instructions as well as our unit wiring diagram, 
and wire accordingly. Avoid mounting the thermostat in 
the following locations:

1.

Cold areas—Outside walls or areas where drafts may 
affect the operation of the control.

2. Hot areas—Areas where the sun’s rays, radiation, or 

warm air currents may affect control operation.

3. Dead areas—Areas where air cannot circulate freely, 

such as behind doors or in corners.

The 

initial heat anticipator setpoint should equal the heater 
control circuit’s current amperage draw when the unit is 
firing. This current should be measured for the best
