FIRE, INJURY OR DEATH HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
When the furnace is installed in a residential garage, the
burners and ignition sources nmst be located at least 18 in.
(457 ram) above the floor. The furnace must be located or
protected to avoid damage by vehicles. When the furnace is
installed in a public garage, airplane hangar, or other
building having a hazardous atmosphere, the furnace nmst
be installed in accordance with the NFPA 54/ANSI
Z223.1-2009 or CAN/CSA B149.2-2010. (See Fig. 5.)
FIRE HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
Do not install the furnace on its back or hang furnace with
control compartment facing downward. Safety control
operation will be adversely affected. Never connect
return-air ducts to the back of the furnace. (See Fig. 4.)
Location Relative to
Cooling Equipment
The cooling coil nmst be installed parallel with, or on the
downstream side of the unit to avoid condensation in the heat
exchangers. When installed parallel with the furnace, dampers or
other flow control must prevent chilled air from entering the
furnace. If the dampers are manually operated, they nmst be
equipped with means to prevent operation of either unit unless the
damper is in the full-heat or full-cool position.
