This w ater heater is a pow er vented appliance and is designed to vent its
products of combustion through 2'' (5.1 cm) or 3'' (7.6 cm) diameter vent
pipe to the outdoors. The w ater heater may be either vented horizontally
through the w all or vertically through the roof. Use a 3'' (7.6 cm) to 2''
(5.1 cm) reducer to connect to the vent outlet w hen using 3'' (7.6 cm)
vent pipe. Apply proper cement at joint locations. Table 5 lists the
maximum vent lengths for this w ater heater using 2'' (5.1 cm) vent pipe. If
possible, locate the w ater heater so that the venting length and number of
elbow s are kept to the minimum distance necessary to reach the outside. If
the installation requires venting lengths that exceed the lengths listed for
2'' (5.1 cm) vent pipe in Table 5 then use 3'' (7.6 cm) vent pipe for the
vent connector.
Table 6 lists the venting distances allow ed w ith 3'' (7.6 cm) diameter vent
pipe. When venting with 3'' (7.6 cm) vent pipe, use a 3'' (7.6 cm) to 2''
(5.1 cm) reducer to exit through the building w all w ith 2'' (5.1 cm) vent
pipe. Use the 2'' (5.1 cm) vent terminal supplied w ith the w ater heater to
terminate on the outside of the building. If the length of the 2'' (5.1 cm)
needed to go through the w all is greater than 14'' (35.6 cm), use 3'' (7.6
cm) vent pipe to go through the w all and reduce to 2'' (5.1 cm) vent pipe
immediately after exiting the outside w all. Refer to the venting illustrations
on the follow ing pages. Make sure the vent pipe terminal is at least 1'' (2.5
cm) aw ay from the edge of the w all.
