Fire or explosion hazard.
Gas connector must be properly installed, cannot
go through the side of the furnace, and can not be
used inside the furnace.
Failure to properly install gas connector can
result in property damage, bodily injury and/or
death.
Additional LP Piping Requirements
• Have a licensed LP gas dealer make all connections at
storage tank and check all connections from tank to fur-
nace.
• If copper tubing is used, it MUST comply with limitation set
in Local Codes, or in the absence of local codes, the gas
codes of the country having jurisdiction.
• Two-stage regulation of LP gas is recommended.
FinalCheck
• Test all pipe for leaks.
• If orifices where changed, make sure they are checked for
leaks.
• During pressure testing of gas piping system, observe the
following:
a. If test pressure does not exceed 1/2 PSIG, isolate the
furnace by closing its individual manual shutoff valve.
b. If test pressure exceeds 1/2 PSIG, the furnace and its in-
dividual shutoff valve must be disconnected from the gas
supply system.
• To check for leaks apply soap suds or a liquid detergent to
each joint. Bubbles forming indicate a leak.
• Do not use an open flame to test for gas leaks. Fire or ex-
plosion could occur.
• Correct even the smallest leak at once.
Fire or explosion hazard.
Liquid petroleum (LP) gas is heavier than air and
will settle and remain in low areas and open
depressions.
Thoroughly ventilate area and dissipate gas. Do
NOT use a match or open flame to test for leaks,
or attempt to start up furnace before thoroughly
ventilating area.
An open flame or spark can result in property
damage, personal injury and/or death.
6. ElectricalWiring
Power SupplyWiring
The furnace MUST be electrically wired and grounded in accor-
dance with local codes, or in the absence of local codes, the appli-
cable national codes.
Field wiring connections must be made inside the furnace con-
nection box. A suitable strain relief should be used at the point the
wires exit the furnace casing.
Copper conductors must be used. Line voltage wires should be
sized for the input amps stated on the rating plate. Furnace should
be connected to its own separate circuit.
Thermostat
Thermostat location has an important effect on the operation of
the unit. Follow instructions included with thermostat for correct
mounting and wiring.
Low voltage connections to furnace must be made on terminal
board to fan control.
Set thermostat heat anticipator in accordance with the Technical
Support Manual.
Optional Equipment
All wiring from furnace to optional equipment MUST conform to
local codes or, in the absence of local codes, the applicable na-
tional codes. Install wiring in accordance with manufacturer's
instructions.
Humidifier/Electronic Air Cleaner
The furnace is wired for humidifier and/or electronic air cleaner
connection.
CAUTION
Do NOT exceed 115V/0.8 amp maximum current load for both
the EAC terminal and the HUM terminal combined.
NOTE: The humidifier will be powered when the furnace is fired
and the circulating air blower comes on. The electronic air cleaner
will be powered anytime the thermostat calls for air movement.
However, the electronic air cleaner is NOT energized during con-
tinuous fan operation controlled by the electronic fan control.
