GENERAL INSTALLATION INSTRUCTIONS
The manufacturer assumes no responsibility for equipment
installed in violation of any code or regulation.
It is recommended that Manual J of the Air Conditioning
Contractors Association (ACCA) or A.R.I. 230 be followed in
estimating heating requirements. When estimating heating re-
quirements for installation at Altitudes above 2000 ft., remem-
ber the gas input must be reduced (See combustion and input
check page 31).
Material in this shipment has been inspected at the fac-
tory and released to the transportation agency without
known damage. Inspect exterior of carton for evidence
of rough handling in shipment. Unpack carefully after
moving equipment to approximate location. If damage to
contents is found, report the damage immediately to the
delivering agency.
Codes and local utility requirements governing the installation
of gas fired equipment, wiring, plumbing, and flue connections
must be adhered to. In the absence of local codes, the instal-
lation must conform with latest edition of the National Fuel
Gas Code ANSI Z223.1 • National Installation Code, CAN/CGA
B149.1. The latest code may be obtained from the American
Gas Association Laboratories, 400 N. Capitol St. NW, Wash-
ington D.C. 20001.

These Furnaces have been classified as CATEGORY IV fur-
naces in accordance with latest edition of ANSI Z21.47 stan-
dards • CSA 2.3. Category IV furnaces operate with positive
vent static pressure and with a flue loss less than 17 percent.
These conditions require special venting systems, which must
be gas tight and water tight. These Category IV Direct Vent
Furnaces are approved for installation in Manufactured/ Mobile
housing when used with BAYMFGH100A.
LOCATION AND CLEARANCES
▲
WARNING
!
FIRE HAZARD. DO NOT INSTALL THE FURNACE DI-
RECTLY ON CARPETING, TILE OR OTHER COMBUSTIBLE
MATERIAL OTHER THAN WOOD FLOORING.
▲
CAUTION
!
Do NOT install the Furnace in a corrosive or contaminated
atmosphere.
Failure to follow this caution could result in early
equipment failure.
The location of the Furnace is normally selected by the archi-
tect, the builder, or the installer. However, before the Furnace
is moved into place, be sure to consider the following require-
ments:
1. Is the location selected as near the chimney or vent and
as centralized for heat distribution as practical?
2. Do all clearances between the Furnace and enclosure
equal or exceed the minimums stated in Clearance Table
on the Outline Drawings?
3. Is there sufficient space for servicing the Furnace and
other equipment? A minimum of 24 inches front accessi-
bility to the Furnace must be provided. Any access door or
panel must permit removal of the largest component.
4. Are there at least 3 inches of clearance between the Fur-
nace combustion air openings in the front panel and any
closed panel or door provided?
5. Are the ventilation and combustion air openings large
enough and will they remain unobstructed? If outside air
is used, are the openings set 12" above the highest snow
accumulation level?
6. Allow sufficient height in supply plenum above the Fur-
nace to provide for cooling coil installation, if the cooling
coil is not installed at the time of this Furnace installa-
tion.
IMPORTANT: The Furnace must be installed level.
The only allowable variation would be slightly to the
left and/ or forward in upflow installations or slightly
toward the front in horizontal installations. This is
necessary for proper condensate drainage.
7. A Furnace shall be installed so electrical components are
protected from water.
8. If the Furnace is installed in a
garage
, it must be installed
so that the burners, and the ignition source are located
not less than 18 inches above the floor and the Furnace
must be located or protected to avoid physical damage
from vehicles.
