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 may need to be reduced (See High
Altitude Installation).
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 installation 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 • CAN/ CGA
2.3 standards.
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.
