be the preferred venting option. To save time and cost, carefully
consider venting installation and location.
10. Horizontal lengths of exhaust vent must slope back towards
the boiler not less than ¼” per foot to allow condensate to drain
from the vent pipe.
11. The exhaust vent must terminate where vapors cannot make
accidental contact with people or pets, or damage shrubs or
plants.
12. In vacant chimney applications, install and seal a rain cap
over existing chimney openings.
13. All piping must be fully supported. Use pipe hangers at a
minimum of 4 foot intervals to prevent sagging of the pipe
where condensate may form.
14. Do not use the boiler to support any piping.
15. Ensure the outdoor exhaust vent termination is screened to
prevent blockage caused by debris or birds.
16. Ensure the outdoor intake pipe termination is screened to
prevent blockage caused by debris or birds.
The following table lists optional exhaust/intake terminations
available from Westinghouse:
H. Applications
1. Direct Vent Installation of Exhaust and Intake
If installing a direct vent option, combustion air must be drawn
from the outdoors directly into the boiler intake, and exhaust
must terminate outside. There are three basic direct vent
options detailed in this manual: 1. Side Wall Venting, 2. Roof
Venting, and 3. Unbalanced Venting.
Be sure to locate the boiler such that the exhaust vent and
intake pipe can be routed through the building and properly
terminated. Different vent terminals can be used to simplify and
eliminate multiple penetrations in the building structure (see
Optional Equipment in Venting Section). The exhaust vent and
intake pipe lengths, routing and termination methods must all
comply with the methods and limits given in the Venting section
of this manual.
When installing a combustion air intake from outdoors, care
must be taken to utilize uncontaminated combustion air.
NOTE:
To prevent combustion air contamination, see Table 1.
Take extra precaution to adequately support the weight of vent
pipes terminating through the roof. Failure to properly support
roof terminated piping could result in property damage, serious
injury, or death.

NOTE:
These drawings are meant to demonstrate system
venting only. The installer is responsible for all equipment and
detailing required by local codes.
All vent pipes must be glued, properly supported, and the
exhaust pitched a minimum of 1/4” per foot back to the
boiler to allow drainage of condensate. When placing support
brackets on vent piping, the first bracket must be within 1 foot
of the boiler and the balance of 4 foot intervals on the vent
pipe. Venting must be readily accessible for visual inspection
from the first three feet from the boiler.
