WARNING
!
The cabinet must have an uninterrupted or unbroken ground
according to National Electrical Code, ANSI/NFPA 70 - “latest
edition” and Canadian Electrical Code, CSA C22.1 or local
codes to minimize personal injury if an electrical fault should
occur. A failure to follow this warning could result in an
electrical shock, fire, injury, or death.

WARNING
!
To prevent injury or death due to electrical shock or contact
with moving parts, lock unit disconnect switch in the open
position before servicing the unit. Failure to follow this
warning could result in electrical shock, personal injury, or
death.
▲
CAUTION
!
The integrated furnace control is polarity sensitive. The hot
leg of the 115 VAC power must be connected to the BLACK
factory lead.
Make wiring connections to the unit as indicated on enclosed
wiring diagram. As with all gas appliances using electrical power,
this furnace shall be connected into a permanently live electric
circuit. It is recommended that it be provided with a separate
“circuit protection device” electric circuit. The furnace must be
electrically grounded in accordance with local codes or in the
absence of local codes with the National Electrical Code,
ANSI/NFPA 70 “latest edition” or Canadian Electrical Code,
CSA C22.1, if an external electrical source is utilized.
All field supplied wiring must conform with the temperature
limitation for Type T wire [63° F (35° C)], when installed in
accordance with these instructions and wiring diagrams supplied
with the furnace. A disconnecting means must be located within
sight from, and readily accessible to, the furnace.
Refer to the Maintenance and Service section of the literature for
unit wiring diagrams in addition to the diagram inside the
blower door.

CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each
appliance connected to the venting system being
placed into operation could result in carbon monoxide
poisoning or death.
The following steps shall be followed for each appliance
connected to the venting system being placed into
operation, while all other appliances connected to the
venting system are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 or the CAN/CGA B149
Installation Codes and these instructions. Determine
that there is no blockage or restriction, leakage,
corrosion and other deficiencies which could cause an
unsafe condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which the
appliance(s) connected to the venting system are
located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not
connected to the venting system. Turn on any exhaust
fans, such as range hoods and bathroom exhausts, so
they are operating at maximum speed. Do not operate
a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat
so appliance is operating continuously.
7. If improper venting is observed during any of the above
tests, the venting system must be corrected in
accordance with the National Fuel Gas Code,
ANSI Z221.1/NFPA 54 and/or CAN/CGA B149
Installation Codes.
8. After it has been determined that each appliance
connected to the venting system properly vents where
tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other gas-fired
burning appliance to their previous conditions of use.
