Vent Assem Bly Illustrations - Suburban DD-17DSI Service Manual

Venting- By definition of a Direct Vent Sealed Combustion Furnace, it must be vented to the outside atmosphere and also draw combustion air
from outdoors. Therefore, it is imperative that the vent be unobstructed and there must be a seal between the exhaust and intake (caulking) . Refer
to the vent assembly installation in the manual. The vent must be straight. There can be no offsets or turns in the vent. All vent tubes which
connect to the furnace exhaust and intake must overlap a minimum of 1/2" on intake, and 1 1/4" on exhaust. Check your furnace model
number for vent installation procedures. Vents cannot be altered as supplied from the factory.
