HORIZONTAL VENTING

(Upflow/ Horizontal)
CAUTION
!
When the vent pipe is exposed to temperatures below
freezing, e.g., 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 will not be required. If domestic water pipes
are not protected from freezing then the space meets the
condition of a heated space.
NOTE: If your furnace comes with a factory supplied 2" X 3"
offset reducing coupling is used for 3" vent pipe installation,
make sure the marking "TOP" is located on the top side of
the pipe.
The straight side of the coupling must be on bottom for
proper drainage of condensate. See Figure 27.
