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 15 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 humidi
fi
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.
H3.22
SHUT OFF ELECTRICAL POWER AT THE FUSE BOX OR SERVICE PANEL BEFORE
MAKING ANY ELECTRICAL CONNECTIONS. FAILURE TO DO SO CAN CAUSE
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.

H19.1
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.
