WARNING: Inducer housing outlet cap must be in-
stalled and fully seated against inducer housing. Clamp
must be tightened to prevent any condensate leakage.
Failure to follow this warning could result in electrical
shock, fire, personal injury, or death.
c. Install pipe support (factory-supplied in loose parts bag)
into selected furnace casing vent pipe hole. Pipe support
should be positioned at bottom of casing hole.
d. Be certain that mating surfaces of inducer housing
connection, elastomeric coupling, and 2-in. diameter
vent pipe are clean and dry. Assemble the elastomeric
(rubber) vent coupling (with 2 loose clamps) onto
inducer housing connection. Insert the 2-in. diameter
vent pipe through the elastomeric (rubber) coupling and
fully into inducer housing connection until it bottoms on
the internal stop. Tighten both clamps to secure the pipe
to inducer housing. Tighten the clamp screws to 15
in.-lb. of torque.
