Understand and pay particular attention to the signal words 

DANGER

,

WARNING

, or 

CAUTION

DANGER 

indicates an 

imminently

 hazardous situation, which, if not

avoided, 

will result in death or serious injury

.

WARNING 

indicates a 

potentially

 hazardous situation, which, if not

avoided, 

could result in death or serious injury

.

CAUTION 

indicates a potentially hazardous situation, which, if not

avoided 

may  result  in  minor  or  moderate  injury.

 It is also used to

alert against unsafe practices and hazards involving only property dam-
age.

SPECIFIC SAFETY RULES AND PRECAUTIONS

1.

Only Natural gas or Propane (LP) gas are approved for use with
this furnace.

2.

Install this furnace only in a location and position specified in these
instructions.

3.

A gas-fired furnace for installation in a residential garage must be
installed as specified in these instructions.

4.

Provide adequate combustion and ventilation air to the furnace
space as specified in these instructions.

5.

Combustion products must be discharged outdoors. Connect this
furnace to an approved vent system only, as specified in these
instructions in Section VII: Combustion Air and Vent System. 

6.

Test for gas leaks as specified in these instructions.

7.

Always install the furnace to operate within the furnace’s intended
temperature rise range. Only connect the furnace to a duct system
which has an external static pressure within the allowable range, as
specified on the furnace rating plate.

8.

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 may also be handled by duct(s) sealed to the furnace
casing and terminating outside the space containing the furnace.
The return air duct system is not required by the furnace manufac-
turer provided the combustion air and vent system have been
installed and maintained as a Two Pipe Sealed Combustion Air
System and provided a return air duct system and return air plenum
are not required by state, local, or regional codes.

9.

It is permitted to use the furnace for heating of buildings or struc-
tures under construction where the application and use must com-
ply with all manufacturer’s installation instructions including:

• Proper vent installation
• Furnace operating under thermostatic control
• Return air duct sealed to the furnace
• Air filters in place
• Set furnace input rate and temperature rise per rating plate mark-

ing

• Means for providing outdoor air required for combustion
• Return air temperature maintained between 55ºF (13ºC) and

80ºF (27ºC)

• The 

air filter must be replaced

 upon substantial completion of

the construction process

• Clean furnace, duct work and components upon substantial com-

pletion of the construction process, and verify furnace-operating
conditions including ignition, input rate, temperature rise and
venting, according to the manufacturer’s instructions.

10. When installed in a Manufactured (Mobile) Home, combustion air

shall not be supplied from occupied spaces.

11. The size of the unit must be based on an acceptable heat loss cal-

culation for the structure. ACCA, Manual J or other approved meth-
ods may be used.

12. When moving or handling this furnace prior to installation, always

leave the doors on the furnace to provide support and to prevent
damage or warping of the cabinet. When lifting the furnace by the
cabinet, support the ends of the furnace rather than lifting by the
cabinet flanges at the return air openings (bottom or sides) or sup-
ply air opening.

13. When lifting the furnace, it is acceptable to use the primary heat

exchanger tubes as a lifting point, provided that the tubes are lifted
at the front of the heat exchangers where attached to the vestibule
panel. Do not use the top return bend of the heat exchangers as lift-
ing points as the tubes may shift out of position or their location
brackets/baffles.

14. Manufactured (Mobile) Home Installation: 

This appliance must

be installed in a two-pipe (direct vent) configuration. The combus-
tion air pipe must terminate in the same atmospheric zone, external
to the building.

15. Modular Home Installations: 

A (two pipe) direct vent configura-

tion. This configuration has a combustion air pipe and the vent pipe
that terminate in the same atmospheric zone, external to the build-
ing, Refer to Figures 23 or 24 for combustion air and vent termina-
tions.

16.

Modular Home Definition:

 Factory-built home constructed to the

state, local, or regional code where the house will be located. The
home is transported in one or more modules and joined at the
home site.

17.

Mobile Home Definition:

 Factory-built home constructed, trans-

ported and installed under the federal building code administered
by the U.S. Department of Housing and Urban Development (HUD
Code), rather than to building codes at their destination. The home
is built, transported, installed on a non-removable chassis.

SAFETY REQUIREMENTS

A manufactured (mobile) home installation must conform with the
Manufactured Home Construction and Safety Standard, Title 24
CFR, Part 3280, or when this standard is not applicable, the
Standard for Manufactured Home Installations (Manufactured
Home Sites, Communities, and Set-ups) ANSI/NCS A225.1, and
/or CAN/CSA Z240 MH Series Mobile Homes. Furnaces have
been certified to the latest edition of standard ANSI Z21-47 • CSA
2.3.

 WARNING

Improper installation may create a condition where the operation of
the product could cause personal injury or property damage.
Improper installation, adjustment, alteration, service or mainte-
nance can cause injury or property damage. Failure to carefully
read and follow all instructions in this manual can result in fur-
nace malfunction, death, personal injury, and/or property dam-
age. 
Only a qualified contractor, installer, or service agency should
install this product.

 WARNING

FIRE OR EXPLOSION HAZARD
Failure to follow the safety warnings exactly could result in serious
injury, death or property damage.
Never test for gas leaks with an open flame. Use a commercially
available soap solution made specifically for detection of leaks to
check all connections. A fire or explosion may result causing prop-
erty damage, personal injury or loss of life.

!

 CAUTION

This product must be installed in strict compliance with the installa-
tion instructions and any applicable local, state, and national codes
including, but not limited to building, electrical, and mechanical
codes.
