The capacity of the induced draft blower declines with increasing altitude due to
a reduction in the air density. In order to assure safe and reliable performance
of the water heater, contact the supplier for high altitude kit.

Vent Pipe Preparation and Joining

Most failures in vent systems result from improper preparation and joining of
pipe and fittings. The guidelines below must be followed when installing the
venting system. If you have any question about the application or installation of
the venting system, contact the vent pipe manufacturer, supplier, or your
plumbing professional.
1) Specific cleaners, solvents, primers and cements are available for PVC,
CPVC, and ABS pipe. Be sure these materials match the type of pipe to be
installed. The vent pipe manufacturers joining instructions must be followed
in all cases. Never use all-purpose cements, commercial glues and
adhesives or ABS cement to join PVC or CPVC pipe and fittings. Refer to
the table at the beginning of the "Venting" section for approved primers and
cements.
