WARNING
It is extremely important to
maintain at least the minimum
separation of exhaust vent
termination from boiler intake
air as illustrated in figures
5, 8 and 13. Failure to do so
can result in a dangerous
situation where exhaust
gasses are re-ingested with
combustion air. Damage to
the boiler can result from
a failure to maintain these
separations. Improper
installation will void the
warranty.
WARNING
In areas of high snowfall,
Users must be advised to
check side wall vent and
air intake terminations on
a regular basis to ensure
blockage does not occur.

Use a 45° elbow on the exhaust termination to launch the plume up and off
the sidewall, for protection of wall.
•
Bird screen of 1/4" stainless steel or plastic mesh eg. (IPEX System 636 drain
grate for CPVC systems) is useful to guard against foreign objects.
