HORIZONTAL VENTING
NOTE:
Vent termination kit BAYAIR30AVENTA or BAYVENT200B
may be used instead of the horizontal and vertical termi-
nation options shown in the following figures.
For Canadian applications, venting systems must meet
ULC-S636 requirements..

CAUTION
!
When the vent pipe is exposed to temperatures below
freezing, i.e., when it passes through unheated spaces,
etc., the pipe must be insulated with 1/2 inch (22.7 mm)
thick Armaflex-type insulation or equal. If the space is
heated sufficiently to prevent freezing, then the insula-
tion would not be required. If domestic water pipes are
not protected from freezing then it is assumed the space
meets the condition of a heated space.

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Do not replace any of the factory supplied venting
components with field fabricated parts. Failure to fol-
low this safety warning exactly could result in dam-
aged vents, damaged components, carbon monoxide
poisoning, or death.
POSSIBLE CONFIGURATIONS FOR TWO PIPE VENTING SYSTEMS WHEN
BOTH TERMINATIONS ARE LOCATED IN THE SAME PRESSURE ZONE
