Johnson Controls Ducted Systems
SPECIFIC SAFETY RULES AND PRECAUTIONS
• Only Natural gas is approved for use with this furnace.
• Install this furnace only in a location and position specified in
these instructions.
• A gas-fired furnace for installation in a residential garage must be
installed as specified in these instructions.
• Provide adequate combustion and ventilation air to the furnace
space as specified in these instructions.
• Combustion products must be discharged outdoors. Connect this
furnace only to an approved vent system as specified in SEC-
TION VII: COMBUSTION AIR AND VENT SYSTEM of these
instructions.
• Test for gas leaks as specified in these instructions.
• Always install the furnace to operate within the furnace’s intended
temperature rise range. Connect the furnace only to a duct sys-
tem that has an external static pressure within the allowable
range, as specified on the furnace rating plate.
• When a furnace is installed so supply ducts carry air circulated by
the furnace to areas outside the space containing the furnace, the
return air must also be handled by a duct or ducts sealed to the
furnace casing and terminating outside the space containing the
furnace.
• Do not use this furnace for heating of buildings or structures
under construction.
• When installed in a non-HUD-approved modular home or building
constructed on-site, combustion air must not be supplied from
occupied spaces.
• The size of the unit must be based on an acceptable heat loss
calculation for the structure. ACCA, Manual J, or other approved
methods can be used.
• When moving or handling this furnace before installation, leave
the doors on the furnace to provide support and prevent damage
or warping of the cabinet. When lifting the furnace by the cabinet,
support the ends of the furnace rather than lifting the furnace by
the cabinet flanges at the return air openings (bottom or sides) or
supply air opening.
• 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 lifting points because the tubes can 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 Figure 6 for return air plenum dimensions. The plenum
must be installed according to the instructions.
• Provide clearances from combustible materials as listed in Table
1.
• 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 in 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 must 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-Hz power supply. DO NOT CONNECT THIS APPLI-
ANCE TO A 50-Hz POWER SUPPLY OR A VOLTAGE ABOVE
130 V.
• Install the furnace so the electrical components are protected
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 must 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 apply.
COMBUSTION AIR QUALITY
(LIST OF CONTAMINANTS)
The furnace requires
OUTDOOR AIR
for combustion when the furnace
is located in any of the following environments:
• Buildings with indoor pools
• Chemical exposure
• Commercial buildings
• Hobby or craft rooms
• Laundry rooms
• Furnaces installed near chemical storage areas
• Restricted environments
The furnace requires
OUTDOOR AIR
for combustion when the furnace
is located in an area where the furnace is exposed to the following sub-
stances and/or chemicals.
• Antistatic fabric softeners for clothes dryers
• Carbon tetrachloride
• Cements and glues
• Chlorine based swimming pool chemicals
• Chlorinated waxes and cleaners
• Cleaning solvents (such as perchloroethylene)
• Deicing salts or chemicals
• Halogen type refrigerants
• Hydrochloric acid
• Masonry acid washing materials
• Permanent wave solutions
• Printing inks, paint removers, varnishes, etc.
• Water softening chemicals
When outdoor air is used for combustion, the combustion air intake duct
system termination must be located external to the building in an area
where there is no exposure to the substances listed above.
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 maintenance
can cause injury or property damage.
Failure to carefully read and
follow all instructions in this manual can result in furnace mal-
function, death, personal injury, and/or property damage.
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 property
damage, personal injury or loss of life.
IMPORTANT:
During installation, doors must remain on the furnace
when moving or lifting.
