Electrical Wiring & 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. Th
e amperage rating is 15
amps or less.
Each furnace requires a dedicated 20 amp over-current device, either
a 20 amp circuit breaker or a 20 amp Type D time delay fuse. It is
permissible to connect furnace accessories such as humidifi er trans-
formers, condensate pumps and electronic air cleaners. If adding ac-
cessory 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.
In Canada, all electrical work must be in accordance with the latest
edition of CSA-C22.1, Canadian Electrical Code Part 1, and any ap-
plicable local code.

WARNING
• THE FURNACE CABINET MUST HAVE AN UNIN-
TERRUPTED GROUND.
• A GROUND WIRE IS PROVIDED IN THE ELECTRI-
CAL 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.
!
WARNING
SHUT OFF ELECTRICAL POWER AT THE FUSE BOX
OR SERVICE PANEL BEFORE MAKING ANY ELEC-
TRICAL CONNECTIONS. FAILURE TO DO SO CAN
CAUSE ELECTRICAL SHOCK RESULTING IN PER-
SONAL INJURY OR LOSS OF LIFE.
In some circumstances, high inlet pressure can be remedied with the
use of an in-line appliance regulator. If an in-line appliance regulator
is used, ensure that it has the capacity to adequately handle the gas
volume required by the furnace and any other appliances receiving
gas from the header serving the furnace.
