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
requirements for installation at Altitudes above 2000 ft.,
remember the gas input must be reduced (See combustion
and input check page 31).
Material in this shipment has been inspected at the
factory 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 installa-
tion of gas fired equipment, wiring, plumbing, and flue
connections must be adhered to. In the absence of local codes,
the installation 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, Washington D.C. 20001.

These Furnaces have been classified as CATEGORY IV
furnaces in accordance with latest edition of ANSI Z21.47
standards • 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 Manu-
factured/ Mobile housing when used with BAYMFGH001A.

LOCATION AND CLEARANCES

WARNING
!
FIRE HAZARD. DO NOT INSTALL THE FURNACE DIRECTLY
ON CARPETING, TILE OR OTHER COMBUSTIBLE MATE-
RIAL 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
architect, the builder, or the installer. However, before the
Furnace is moved into place, be sure to consider the following
requirements:
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.

Installer's Guide
4. Are there at least 3 inches of clearance between the
Furnace 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 (18" minimum in Canadian applica-
tions)?
6. Allow sufficient height in supply plenum above the
Furnace to provide for cooling coil installation, if the
cooling coil is not installed at the time of this Furnace
installation.
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.
