5 - COMBUSTION AIR AND VENT PIPING
5.8 Twin Pipe Systems
Twin pipe venting allows exhaust flue and intake flue to
be separated from each other. Fresh air is drawn in at a
different area from the flue terminal location.
A.
Twin Pipe CPVC System
CPVC is approved for boiler exhaust. CPVC or PVC are
both approved for air intake.
To transition from Coaxial at the top of the boiler to Twin
Pipe CPVC/PVC a kit is available.
B.
Twin Pipe Polypropylene System
Single wall polypropylene is used for both exhaust and
air intake piping. PVC can be used on
intake only
on
twin pipe applications.
Use the appropriate transition kit to change from
polypropylene to PVC. To transition from Coaxial, at the
top of the boiler to Twin Pipe polypropylene venting an
adapter kit is available.
C.
Twin Pipe Separated Flue
Exhaust and combustion air intake are not located in
same general location.
D.
Twin Pipe - Common Atmospheric Zone
Termination
Exhaust and combustion air intake are located in same
general location and are of equal length.
Grade, Snow
& Ice
Maintain 12"(305 mm) US, 18"(457
mm) Canada clearance above highest
anticipated snow level, 24" (610 mm)
above roof.
Avoid locations where snow may drift
and block vent and combustion air.
Ice or snow may cause boiler to shut
down if vent or combustion air becomes
obstructed.
WARNING
Asphyxiation hazard! Improper installation could
result in death or serious injury. Read Twin
Pipe Installation Instructions completely and
understand all requirements before beginning
installation.
