Installation Instructions
Unit Specifications
This appliance is intended for new construction or retrofit
replacement of most 42” x 16” Package Terminal Air Con-
ditioners. Confirm the electrical rating of this appliance
matches the electrical supply available before beginning
installation (refer to table on page 11).
The efficiency rating of this appliance is a product of
thermal efficiency rating determined under continuous
operating conditions and is determined independently of
any installed system.
Due to high temperatures, the appliance should be located
out of traffic and away from furniture and drapes. Chil-
dren and adults should be alerted to the hazards of high
surface temperatures and should stay away to avoid burns
or clothing ignition. Young children should be carefully
supervised when they are in the same room as the appli-
ance. Clothing or other flammable material should not
be placed on or near the appliance. Any safety screen or
guard removed for service must be replaced before operat-
ing the appliance. More frequent cleaning may be required
due to excessive lint from carpeting, bedding material, etc.
It is imperative that control compartments, burners, and
circulating air passageways of the appliance be kept clean.
Installation and repair should be done by a qualified
service person. The appliance should be inspected
before use and at least annually by a qualified service
person.
Safety Information
A. This appliance does not have a pilot. It is equipped
with an ignition device, which automatically lights
the burner. Do not try to light the burner by hand.
B. BEFORE OPERATING smell all around the appli-
ance area for gas. If your unit uses LP (propane),
be sure to smell next to the floor because LP
(propane) gas is heavier than air and will settle on
the floor.
C. Use only your hand to turn the gas valve knob.
Never use tools. If the knob will not turn by
hand, don’t try to repair it. Call a qualified service
technician. Force or attempted repair may result
in fire or explosion.
D. Do not use this appliance if any part has been
under water. Immediately call a qualified service
technician to inspect the appliance and replace any
part of the control system and any gas valve, which
has been under water.

Any safety screen or guard removed for servicing an appliance must be replaced prior to operating the
appliance.
When installed in the appropriate wall sleeve, this appliance has zero clearance to combustible con-
struction.
The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during
pressure testing of that system at test pressures in excess of
½
psi. The appliance must be isolated from the gas piping
system by closing equipment shutoff valves during any pressure testing of the gas supply piping system at test pressures
equal to or less than
½
psi.
The gas-fired heating design of this appliance requires that the installation of this appliance must conform with local
codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or National Gas
and Propane Installation Code, CSA B149.1. This appliance is only for use with the type of fuel indicated on the rating
plate. This appliance is not convertible for use with other gases.
Inlet gas pressure:

minimum 5” W.C., maximum 14” W.C.
Liquefied:
minimum 11” W.C., maximum 14” W.C.
(Minimum inlet pressures must be maintained for purposes of adjustment.)
