burners and ignition sources must be located at least 18 in.

protected to avoid damage by vehicles. When the furnace is
installed in a public garage, airplane hangar, or other

WARNING
FIRE HAZARD
Failure to follow this warning could result in personal

WARNING
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.
