4.3.2 Vent specifications
An improperly sized venting system may lead to undesired
effects such as the formation of condensate, gas leakage or
spillage.
Install appliance as close to point of vent termination as
possible. The exhaust piping must vent directly to the outside of
the structure.
Horizontal sections of vent must pitch upward towards
termination ¼" for every foot of horizontal length, to prevent the
pooling of condensate, and be supported at 4 foot intervals
with overhead hangers.
Exception: horizontal run between last elbow and termination
must pitch down to termination 1/4" per foot. Note: For
horizontal terminations, venting must terminate once it
penetrates to the outside of the structure. There must be no
sections of vent pipe exposed to the outdoors other than the
termination. Note: Listed thimbles or collars are necessary
where venting passes through wall and ceiling partitions. If the
vent system passes through combustible areas where the vent
clearance requirements cannot be maintained, it is permissible
to chase straight sections of sealed 3 inch single wall vent
through 4 inch (or greater) Type-B vent. The distance to
combustibles using this chase technique is 1 inch. Note: Type-
B vent must never be used as the actual exhaust vent system for
the appliance, as it is not gas tight and illegal for use with this
appliance. This will create a serious health hazard and void the
warranty.
