• Insulate the entire length of vent
pipe, between the elbow where the
pipe exits the wall and the elbow
where the termination is made, with
a closed-cell insulation, such as
"Arm-a-Flex" or "Rub-a-Tex" with a
minimum of 1/2" thickness.
• All elbows installed on the exterior
of the building must be of the long
sweep nature.
• As required for the horizontal piping
ran within the structure, any pipe
ran horizontal outside the structure
must slope upward a minimum of
1/4" per foot run so that condensate
drains toward the furnace.
From the top elbow in the exhaust
pipe, extend a length of PVC pipe
outward so that it terminates exactly
12 inches from the wall. See Figure
18.
The 45,000 BTUH unit only uses kit
RXGY-D02 or D02A. The 60,000
BTUH and 75,000 BTUH units may
use kits RXGY-D02 or D02A or
RXGY-D03 or D03A depending on
pipe lengths and number of elbows.
See Table 2.
