Category IV Installation of Vent/Air Piping
Category IV - Multiple Boiler Installation - Through
the Roof
1. On installations of multiple PRESTIGE boilers, termi-
nate each vent pipe as described in this manual.
2. Each vent termination must be a minimum 12” [30.5
cm] from the adjacent termination for installations in
the U.S. as shown in Fig. 25. For installations in
Canada, provide clearances as required by
CAN/CSA B149.1.

Category IV- Vertical Termination of
Multiple Boilers
Fig. 25:
Category IV - Horizontal - Sidewall
The installation must conform to the requirements of
the authority having jurisdiction or, in the absence
of such requirements, to the National Fuel Gas
Code, ANSI Z223.1/ NFPA 54, and/or Natural Gas and
Propane Installation Code, CAN/CSA B149.1.
For direct vent (sidewall) installations in the
Commonwealth of Massachusetts, the installer must
comply with the additional requirements outlined on
pages 37 and 38.
A gas vent extending through a sidewall should not
terminate near an adjacent wall or below any build-
ing extensions such as roof eaves, balconies or
decks. Failure to comply with the required clear-
ances in this manual could result in severe personal
injury, death or substantial property damage.
If the vent is terminated on a sidewall which is sub-
ject to high winds it is recommended to terminate
the vent using a 45º elbow or tee. A tee provides the
best protection against wind but can expose the
exterior of the house to condensate, while a 45º
elbow provides improved protection from both wind
and condensate.
The information and diagrams outlining the fittings
and method of terminating the vent/combustion air
are directly related to PVC/CPVC vent systems.
When utilizing and AL29-4C® or Polypropylene vent
system there may be some variations. Consult the
appropriate vent manufacturer for recommenda-
tions and clarifications.
