OTHER LOCATION INFORMATION
Sufficient air must be provided to ensure there will not be a
negative pressure in fu rnace room or space. In addition,
there must be a positive seal between furnace and return
air duct to avoid pulling air from furnace room.
When a cooling unit is installed with this fu rnace, the
furnace must be installed parallel with or on the upstream
side of the cooling unit to avoid condensation in fu rnace
heat exchanger. With a parallel flow arrangement, the
dampers or other means used to control flow of air must be
adequate to prevent chilled air from entering the fu rnace
and, if manually operated, must be provided with a means
to prevent operation of either unit unless damper is in the
full heat or cool position.
When furnace is in a residential garage, it must be installed
so that pilot and main burners are located no less than 18
inches above the floor. Also, furnace should be protected
from physical damage by vehicles.
When furnace is in a public garage, airplane hanger, or
other building having hazardous atmosphere, install unit in
accordance with recommended good practice requirements
of the National Fire Protection Association, Inc. Consult
local code authorities for additional location requirements.
