Bryant Induced-Combustion 4-Way Multipoise 310AAV - Manual (Page 5)

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 commer-
cially available soap solution made specifically for the detec-
tion 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 speci-
fied 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 is not to be used for temporary heating of
buildings or structures under construction. See page 7 caution
box regarding the heating of buildings under construction.
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 listed 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. clearance from combustible materials to
supply air ductwork for a distance of 36 inches horizontally
from the furnace. See NFPA 90B or local code for further
requirements.
13. These furnaces SHALL NOT be installed directly on carpet-
ing, 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 Coil Assembly Part No.
CD5 or CK5, or when Coil Box Part No. KCAKC is used. See
Fig. 2 for clearance to combustible construction information.
INTRODUCTION
This Series 120/C 4–way multipoise Category I fan-assisted
furnace is CSA design-certified. A Category I fan-assisted furnace
is an appliance equipped with an integral mechanical means to
either draw or force products of combustion through the combus-
tion chamber and/or heat exchanger. The furnace is factory-
shipped for use with natural gas. A CSA (A.G.A. and C.G.A.)
listed gas conversion kit is required to convert furnace for use with
propane gas. This furnace is not approved for installation in
mobile homes, recreational vehicles, or outdoors.
This furnace is designed for minimum continuous return-air
temperature of 60°F db or intermittent operation down to 55°F db
such as when used with a night setback thermostat. Return-air
temperature must not exceed 85°F db. Failure to follow these
return-air temperature limits may affect reliability of heat exchang-
ers, motors, and controls. (See Fig. 3.)
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping brackets and materials before oper-
ating the furnace.
CODES AND STANDARDS
Follow all national and local codes and standards in addition to
these instructions. The installation must comply with regulations
of the serving gas supplier, local building, heating, plumbing, and
other codes. In absence of local codes, the installation must
comply with the national codes listed below and all authorities
having jurisdiction.
