HEATING A COOLING
58ED,PB
Horizontal Gas-Fired Furnaces
American Gas Association, 1515 Wilson Boulevard,
Arlington, VA 22209.
A
WARNING
The furnace cabinet must have an uninterrupted or
unbroken electrical ground to minimize personal
injury if an electrical fault should occur. The unit
must also be electrically grounded in accordance
with local codes, with the National Electrical Codes
ANSI/NFPA No. 70-1984 or the latest edition. Do
not use gas piping as an electrical ground.
INSTALLATION
Step 1 — Select Location
— This furnace may be
located in an attic, basement crawl space, alcove or
suspended from the ceiling of a utility room or basement.
As shown in Table 3, the minimum clearances, or greater,
must be provided between the furnace and adjacent
construction.
A WARNING
Failure to comply with all the recommended clear¬
ances will result in a fire hazard.
If a furnace is to be installed in a residential garage, it
must be installed so the burners and the ignition source
are located not less than 18 in. above the floor and the
furnace must be located or protected to avoid physical
damage by vehicles.
The furnace should be located as close to the chimney
as possible in order to keep vent connections as short and
direct as possible. The furnace should also be located as
near to the center of the air distribution as possible, and
should be mounted level.
Since this furnace is suitable for attic installation, it
must not be installed directly on carpeting, tile or other
combustible material. Line contact is only permissible
between lines formed by the intersection of the furnace
top and two sides and the building joists, studs or
framing. See Fig. 2
A clearance of at least 30 in. should be provided at the
front of the furnace for combustion air and servicing.
For attic installations, the passageway and service area
adjacent to the furnace should have a floor installed.
The areas adjacent to the combustion air openings must
be covered with fireproof board or sheet metal extending
a minimum of 12 in. from the furnace. See Fig. 2.
If the furnace is to be installed in a crawl space, consult
local codes. Use of a concrete pad one to 2 in. thick is
recommended.
If the furnace is to be suspended from the ceiling, it is
necessary to use steel pipe straps around each end of the
furnace. These straps should be attached to the furnace
with sheet metal screws and bolted to the rafters. The
furnace may also be suspended by an angle iron frame
bolted to the rafters.
