Maximum Allowable Exposed Vent Length in Unconditioned Space (Metric)
* Pipe length (ft) specified for maximum pipe lengths located in unconditioned spaces. Pipes located in unconditioned space cannot exceed total allowable pipe length calculated from Table 15.
† Insulation thickness based on R value of 3.5 per in.
Installing the Vent Pipe Adapter and Combustion Air
Pipe Adapter
NOTE: The rubber coupling that attaches to the vent pipe adapter must
be used. The adapter seals the vent pipe to the casing and reduces the
strain on the vent elbow attached to the inducer.
1. Apply the gaskets to the vent pipe and combustion air pipe
adapters. If supplied, remove and discard round center “slug” from
interior of gasket. See Fig. 58.

Fig. 58 – Vent Coupling and Adapter with Gaskets
NOTE: The vent pipe adapter can be distinguished from the inlet pipe
adapter by the absence of an internal pipe-stopping ring. The vent pipe
can pass through the vent pipe adapter; it cannot pass through the inlet
pipe adapter.
2. Align the screw holes in the plastic vent pipe adapter with the
dimples in the casing.
