Electrical Requirements

Electrical Shock Hazard
Electrically ground furnace.
Connect ground wire to green pigtail lead.
Failure to do so can result in death or electrical shock.
The furnace must be grounded and wired in accordance with
local codes or, in the absence of local codes, with the
National Electrical Code ANSI/NFPA No. 70 (latest edition) if
an external electrical source is utilized.
In all instances, other than wiring for the thermostat, the
wiring to be done and any replacement of wire shall conform
with the temperature limitation for Type T wire – 63°F (35°C)
The line voltage supply should be routed through a readily
accessible disconnect located within sight of the furnace. A
junction box on the furnace side panel is provided for line
voltage connections. See the furnace wiring diagram for
specific connection information.
Proper polarity of the supply connections ("HOT" and
"NEUTRAL") must be observed to ensure that safety controls
provide the protection intended.

Gas Supply Requirements

This furnace is equipped for use with natural gas. A conversion
kit is required for use with propane. To order the correct
conversion kit, see "Accessories."
Gas supply piping should be installed in accordance with
local codes and the regulations of the utility. Piping must be
of adequate size to prevent undue pressure drop. Consult the
local utility or gas supplier for complete details on special
requirements for sizing gas piping.
If local codes allow the use of a flexible gas appliance
connector, always use a new listed connector. Do not use a
connector which has previously serviced another gas

Venting Requirements

Adequate provisions for combustion air and ventilation of furnace
must be made. Refer to the National Fuel Gas Code, ANSI
Z223.1/NFPA54 (latest edition), Natural Gas and Propane
Installation Codes (latest editions), or applicable provisions of the
local building codes.
This furnace must be installed only as a direct vent installation. A
direct vent (two pipe) installation supplies all of the necessary air
for combustion from outside the building through an air intake
Contaminated Combustion Air
These furnaces have been approved for use with outdoor
combustion air only. Excessive exposure to the following
substances in the combustion air supply will result in
performance-related problems:
Permanent wave solutions
Chlorinated waxes and cleaners
Chlorine-based swimming pool chemicals
Water softening chemicals
Deicing salts or chemicals
Carbon tetrachloride
Halogen-type refrigerants
Cleaning solvents (such as perchloroethylene)
Printing inks, paint removers, varnishes, etc.
Cements and glues
