lowed in estimating heating requirements. When esti-
mating heating requirements for installation at alti-
tudes 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 ship-
ment. Unpack carefully after moving equipment
to approximate location. If damage to contents is

Failure to follow the safety warnings exactly could re-
sult in serious injury, death or property damage.
Improper servicing could result in dangerous opera-
tion, serious injury, death, or property damage.
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.
f.
The furnace return air temperature range is
between 55 and 80 degrees Fahrenheit.
g.
Clean the furnace, duct work, and components
upon substantial completion of the construction
process, and verify furnace operating conditions
including ignition, input rate, temperature rise
and venting, according to the manufacturer's
instructions.
