FIRE, INJURY OR DEATH HAZARD
Failure to follow this warning could result in personal in-
jury, death and/or property damage.
When the furnace is installed in a residential garage, the
burners and ignition sources must be located at least
18-in. (457 mm) 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 atmo-
sphere, the furnace must be installed in accordance with
the NFPA 54/ANSI Z223.1-2009 or CAN/CSA
B149.1-2010. (See Figure 4)

Location Relative to Cooling
Equipment
The cooling coil must 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 must be
equipped with means to prevent operation of either unit unless
the damper is in the full-heat or full-cool position.
FIRE HAZARD
Failure to follow this warning could result in personal in-
jury, 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 re-
turn-air ducts to the back of the furnace. (See Figure 5)
