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 as 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 SECTION
VII of these instructions.
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 shall also be handled by duct(s) sealed to the furnace cas-
ing and terminating outside the space containing the furnace.
9. It is permitted to use the furnace for heating of buildings or structures
under construction where the application and use must comply 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
marking;
•
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
completion 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 Non-HUD-Approved Modular Home or building
constructed on-site, combustion air shall not be supplied from occu-
pied spaces.
11.The size of the unit should 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 supply
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.
SAFETY REQUIREMENTS
•
Refer to the unit rating plate for the furnace model number, and
then see the dimensions page of this instruction for return air ple-
num dimensions in Figure 13. The plenum must be installed
according to the instructions.
•
Provide clearances from combustible materials as listed under
Clearances to Combustibles.
•
Provide clearances for servicing ensuring that service access is
allowed for both the burners and blower.
•
These models
ARE NOT
CSA listed or approved for installation
into a
HUD Approved Modular Home
or a
Manufactured
(Mobile) Home
.
•
This furnace is not approved for installation in trailers or recre-
ational vehicles.
•
Furnaces for installation on combustible flooring shall not be
installed directly on carpeting, tile or other combustible material
other than wood flooring.
•
Check the rating plate and power supply to be sure that the elec-
trical characteristics match. All models use nominal 115 VAC, 1
Phase, 60-Hertz power supply. DO NOT CONNECT THIS APPLI-
ANCE TO A 50 HZ POWER SUPPLY OR A VOLTAGE ABOVE
130 VOLTS.
•
Furnace shall be installed so the electrical components are pro-
tected from water.
•
Installing and servicing heating equipment can be hazardous due
to the electrical components and the gas fired components. Only
trained and qualified personnel should install, repair, or service
gas heating equipment. Untrained service personnel can perform
basic maintenance functions such as cleaning and replacing the
air filters. When working on heating equipment, observe precau-
tions in the manuals and on the labels attached to the unit and
other safety precautions that may apply.
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 property
damage, personal injury or loss of life.
During installation, doors must remain on the furnace when
moving or lifting.
This product must be installed in strict compliance with the installation
instructions and any applicable local, state, and national codes
including, but not limited to building, electrical, and mechanical codes.
