Sound Suppressor; Side Wall Vent Installation; Vertical Vent Installation - American Water Heater Powerflex Installation And Operating Manual

SOUND SUPPRESSOR

Included with this water heater is a Tee fi tting confi gured
as a sound suppressor. Depending on the confi guration
of the water heater this will be either a 2" or a 3" fi tting.
The sound suppressor can be fi tted to the venting near
the blower assembly or used as the exhaust termination
(see Figure 41 thru Figure 44).

Side Wall Vent Installation

The preferred location for the Sound Suppressor is 12"
away from the blower as shown in Figure 41 and Figure
42 and serves as the fi rst 90° elbow. Alternatively, it can
be used as the termination for the venting. If the Sound
Suppressor is used as the vent termination the Vent
Termination Screen (see "Vent Pipe Termination" section)
must be installed in the straight through end of the Sound
Suppressor (see Figure 43).
