WARNING
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.
CAUTION
!
Improper installation, adjustment, alteration, service, 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, or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory-authorized kits or accessories
when modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
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. Read these
instructions thoroughly and follow all warnings or cautions
included in literature and attached to the unit.

NOTE
and
NOTICE
are used to
highlight suggestions which will result in enhanced installation,
reliability, or operation.
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 spe-
cified in the “Location” section of these instructions.
3. Provide adequate combustion and ventilation air to the fur-
nace space as specified in “Air for Combustion and Ventila-
tion” section.
4. Combustion products must be discharged outdoors. Con-
nect this furnace to an approved vent system only, as spe-
cified in the “Venting” section of these instructions.
5. Never test for gas leaks with an open flame. Use a commer-
cially available soap solution made specifically for the de-
tection of leaks to check all connections, as specified in the
“Gas Piping” section.
6. Always install furnace to operate within the furnace’s inten-
ded temperature--rise range with a duct system which has an
external static pressure within the allowable range, as spe-
cified 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 contain-
ing 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.
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 of these instruc-
tions.
10. These Multipoise Gas--Fired Furnaces are CSA design--cer-
tified for use with natural and propane gases (see furnace
rating plate) and for installation in alcoves, attics, base-
ments, 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.
11. See Table 2 for required clearances to combustible con-
struction.
12. Maintain a 1--in. (25 mm) clearance from combustible ma-
terials to supply air ductwork for a distance of 36 in. (914
mm) horizontally from the furnace. See NFPA 90B or local
code for further requirements.
