SOUND SUPPRESSOR
Included with this water heater is a Tee fi tting con fi gured
as a sound suppressor. Depending on the con fi 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 35 thru Figure 38).
Side Wall Vent Installation
The preferred location for the Sound Suppressor is 12”
away from the blower as shown in Figure 35 and Figure
36 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 37).

Vertical Vent Installation
If the venting installation is vertical, directly from the blower
through the roof, the Sound Suppressor may be used
as the vent termination. In such an installation the Vent
Termination Screen (see “Vent Pipe Termination” section)
must be installed in the straight through end of the Sound
Suppressor (see Figure 38).
