2.C Vent and Air Pipe Sizing

This unit is certified to vent as a Category II or Category
IV appliance. Because Category II vent is non-positive,
the vent size may not be the same as the positive
pressure Category IV vent, even when the unit is the
same size. Be sure to follow the instructions in this
manual, based on the type of venting in your installation.
Horizontal vent terminal for stainless steel
The venting must be correct to allow the condensate
Screen for horizontal CPVC vent
to run back to the unit to drain. Route the vent pipe to
Screen for vertical stainless steel vent
the boiler as directly as possible. Seal all joints. Provide
Screen for vertical CPVC vent
adequate hangers as required in the venting system
manufacturer's Installation Instructions, or at least every
4 feet.
Table 3* - Vent Accessories
The unit must not support the weight of the vent pipe.
The maximum equivalent pipe length allowed is
100 feet (30m). Each elbow is considered to be 5 feet
(1.5m). The manufacturer offers accessory kits to use
(Place in section 3.5)
with horizontal and vertical exhaust vent systems, as
shown in Table 7.
