The water heaters covered by this manual are approved to
be installed using the approved vent terminations shown
in this manual. This means that, the installer must use the
adapter listed in Tables 9 and 10 and a short piece of PVC
pipe to complete the end of the vent system with an approved
termination. In Canada, the PVC pipe length must be listed
to ULC636.

VENT INSTALLATIONS
(AL29-4C® is a registered trademark of Allegheny Technologies, Inc.)
The water heaters covered by this manual are approved
to be installed with AL29-4C® stainless steel vent material
using parts from the manufacturers listed in Tables 9 and 10
below. These listed systems must be installed using the vent
manufacturer’s instructions including their listed clearances
to combustible and noncombustible materials. Refer to Table
6 on page 23 for the maximum and minimum equivalent
linear vent lengths and number of elbows that may be used.
However, use Tables 9 and 10 below to find the appropriate
equivalent linear vent lengths for the AL29-4C® elbows.
NOTE: The equivalent lengths of the AL29-4C® elbows are
different than those from smooth walled plastic vents. Consult
Tables 9 and 10 for the correct equivalent linear vent lengths.
Listed vent systems composed of AL29-4C® must not mix
parts from the different manufacturers. The joints of these
products are sealed by internal gaskets. Do not use any
other type of sealant. When assembling these vent systems,
follow the vent manufacturer’s instructions for cleaning and
lubricating the joints, if required. Each section must be locked
together using the method supplied by the vent manufacturer.
