FURNACE RELIABILITY HAZARD
Failure to follow this caution may result in unit component
damage.
Application of this furnace should be indoors with special
attention given to vent sizing and material, gas input rate, air
temperature rise, unit leveling, and unit sizing.
Improper
installation,
adjustment,
maintenance, or use can cause explosion, fire, electrical shock,
or other conditions which may cause death, personal injury or
property damage. Consult a qualified installer, service agency,
local gas supplier, or your distributor or branch for information

Installing and servicing heating equipment can be hazardous
due to gas and electrical components. Only trained and
qualified personnel should install, repair, or service
heating equipment. Untrained personnel can perform basic
maintenance functions such as cleaning and replacing air
filters. All other operations must be performed by trained
service personnel. When working on heating equipment,
observe precautions in literature, on tags, and on labels
attached to or shipped with furnace and other safety
precautions that may apply.
These instructions cover minimum requirements and conform
to existing national standards and safety codes. In some
instances, these instructions exceed certain local codes and
ordinances, especially those that may not have kept up with
changing residential construction practices. We require these
instructions as a minimum for a safe installation.
Follow all safety codes. Wear safety glasses, protective
clothing, and work gloves. Have a fire extinguisher available.

1.
Use only with type of gas approved for this furnace.
Refer to the furnace rating plate.
2.
Install this furnace only in a location and position as
specified in the "Location" section of these instructions.
3.
Provide adequate combustion and ventilation air to the
furnace space as specified in "Air for Combustion and
Ventilation" section.
4.
Combustion products must be discharged outdoors.
Connect this furnace to an approved vent system only,
as specified in the "Venting" section of these
instructions.
5.
Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifically
for the detection of leaks to check all connections, as
specified in the "Gas Piping" section.
6.
Always install furnace to operate within the furnace's
intended temperature−rise range with a duct system
which has an external static pressure within the
allowable range, as specified in the "Start−Up,
Adjustments, and Safety Check" section. See furnace
rating plate.
7.
When a furnace is installed so that supply ducts carry air
circulated by the furnace to areas outside the space
containing the furnace, the return air shall also be
handled by duct(s) sealed to the furnace casing and
terminating outside the space containing the furnace.
See "Air Ducts" section.
8.
A gas−fired furnace for installation in a residential
garage must be installed as specified in the warning box
in the "Location" section. (See Figure 4)
9.
The furnace may be used for construction heat provided
that the furnace installation and operation complies with
the first CAUTION in the LOCATION section on page 7
of these instructions.
10.
These Multipoise Gas−Fired Furnaces are CSA
design−certified for use with natural and propane gases
(see furnace rating plate) and for installation in alcoves,
attics, basements, closets, utility rooms, crawlspaces,
and garages. The furnace is factory−shipped for use
with natural gas. A CSA (A.G.A. and C.G.A.) listed
accessory gas conversion kit is required to convert
furnace for use with propane gas.
