HORIZONTAL VENTING
NOTE:
Vent termination kit BAYAIR30AVENTA or BAYVENT200* may
be used instead of the horizontal and vertical termination
options shown in the following figures. For Canadian applica-
tions ONLY: IPEX 196006 may be used for horizontal and
vertical terminations. IPEX 081216, IPEX 081218, and IPEX
081219 may only be used for horizontal vent terminations.

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 insulation 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.
HORIZONTAL VENTING THROUGH WALL
These furnaces may be installed as direct vent (as shipped)
or as nondirect vent. Installation must conform to national,
state, and local codes.
The vent & inlet terminals must be located at least 12" minimum
above normally expected snow accumulation level (18" minumum
in Canadian applications).
Avoid areas where staining or condensate drippage may be a

problem.
Location of the vent/wind terminal should be chosen to meet the
requirements of Figure 26 for either direct or non-direct vent
applications.
PITCH – Venting through the wall must maintain 1/4" per foot
pitched upward to insure that condensate drains back to the
furnace.
FLUE GAS DEGRADATION – The moisture content of the flue
gas may have a detrimental effect on some building materials.
This can be avoided by using the roof or chimney terminal, venting
option. When wall venting is used on any surface that can be
affected by this moisture, it is recommended that a corrosion
resistant shield (24 inches square) be used behind the vent
terminal. This shield can be wood, plastic, sheet metal, etc. Also,
silicone caulk all cracks, seams and joints within 3 feet of the vent.
COMBUSTIBLE MATERIAL WALL - A minimum clearance
of 1" to combustible materials must be maintained when using
