58TN0B/58TN1B: Installation, Start–Up, Operating and Service and Maintenance Instructions
CAUTION
!
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.
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.
WARNING
!
FIRE, INJURY, OR DEATH HAZARD
Failure to follow this warning could result in property damage, personal
injury, or death.
Do not bypass any of the safety controls in the furnace, including but
not limited to the main limit switch, rollout or burner thermal switch,
and pressure switch/pressure transducer.
Wear safety glasses, protective clothing and work gloves. Have fire
extinguisher available during start-up and adjustment procedures and
service calls.
This is the safety-alert symbol
furnace and in instructions or manuals, be alert to the potential for
personal injury.
Understand the signal words DANGER, WARNING, and CAUTION.
These words are used with the safety-alert symbol. DANGER identifies
the most serious hazards which will result in severe personal injury or
death. WARNING signifies a hazard which could result in personal
injury or death. CAUTION is used to identify hazards which may result
in minor personal injury or product and property damage. NOTE is used
to highlight suggestions which will result in enhanced installation,
reliability, or operation.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear
appropriate protective clothing, safety glasses and gloves when
handling parts, and servicing furnaces.
The following additional safety considerations should be followed for
gas furnaces:
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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
. When you see this symbol on the
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.
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 instructions.
10. These Multipoise Gas-Fired Furnaces are CSA (formerly A.G.A.
and C.G.A.) 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.
11. See Fig. 2 for required clearances to combustible construction.
12. Maintain a 1-in. (25 mm) clearance from combustible materials 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.
13. These furnaces SHALL NOT be installed directly on carpeting, tile,
or any other combustible material other than wood flooring. In
downflow installations, factory accessory floor base MUST be used
when installed on combustible materials and wood flooring. Special
base is not required when this furnace is installed on manufacturer's
cased evaporator coils or when manufacturer's evaporator coil
casing is used, See Fig. 2
information.
