VENTING
Install Vent Termination and Piping
The UltraSaver may be installed with up to 50’ equivalent length
venting.
Notice: For each 45° elbow installed in the run, the length
of the run MUST be reduced by 1.5 feet (45 cm). Reduce the
length of the run three feet (91.4 cm) for every 90° elbow. The
vent terminal elbow does not contribute to the overall vent
length measurement.
See pages 28 through 31 for vent termination and vent run ex-
amples and requirements.
This unit is vented directly out the back using 1-1/2” or 2” PVC
pipe. See Figure 36 for exterior vent hole location.
If 1-1/2” pipe is used, it must be enlarged to 2” pipe prior to exit-
ing the wall into the shroud.
If venting out the back through the wall is not possible (such as
in a basement) the vent pipes may be run in front of the wall (left,
right, or up) inside of the room using an optional deep shroud.
See page 15.
When venting through the wall, be sure to leave 2-3/8” (51mm)
of ue pipe extending through the rear shroud into the room for
connection to the inducer. See Figure 38.

To prevent ue pipe from pushing back into the wall, place a hose
clamp on the pipe against the wall and tighten. See Figure 39.
Figure 39
For direct-vent installations, the inlet air pipe will only extend
1/4” through the wall into the rear shroud. The inlet pipe will butt
against the stopping ange provided with the air pipe kit. See
Figure 40.
