14.1 ELECTRICAL WIRING AND CONNECTIONS
Before proceeding with the electrical connections, ensure that the available electrical supply is compatible with
the voltage, frequency and phase listed on the appliance rating plate.
All furnaces are rated 120 VAC, 60 Hz, 1 Ø. The amperage rating is 12 amps or less.
Each furnace requires a dedicated 15 amp over-current device, either a 15 amp circuit breaker or a 15 amp
Type D time delay fuse. It is permissible to connect furnace accessories such as humidifi er transformers,
condensate pumps and electronic air cleaners. If adding accessory equipment to the furnace circuit, ensure
that the combined amperages listed on the appliance rating plates does not exceed the rating of the over-
current device.

H19.1A
In Canada, all electrical work must be in accordance with the latest
edition of CSA-C22.1, Canadian Electrical Code Part 1, and any
applicable local code.
In the United States, all electrical work must be in accordance with
the latest edition of the National Electrical Code, ANSI / NFPA 70.
Although a suitably located circuit may serve as a service switch, a
separate service switch is recommended. A separate service switch
is necessary if the circuit breaker is in a location where accessing it
would require getting close to the furnace, or if the furnace is located
between the main electrical panel and the entry to the furnace room.
The furnace switch (service switch) should be clearly labeled,
and installed in a location where it is not likely to be mistaken as
being a light switch or similar control.
H3.22

ELECTRICAL SHOCK RESULTING IN PERSONAL INJURY OR LOSS OF LIFE.
• THE FURNACE CABINET MUST HAVE AN UNINTERRUPTED GROUND.
• A GROUND WIRE IS PROVIDED IN THE ELECTRICAL JUNCTION BOX.
• DO NOT USE GAS PIPING AS A GROUND.
FAILING TO GROUND THE FURNACE PROPERLY CAN RESULT IN ELECTRIC SHOCK
RESULTING IN PERSONAL INJURY OR DEATH.
