Figures 30 shows the range of venting options,
it shows possible vent configurations if the
unit is top vented, for vertical and horizontal
terminations, any layout that remains within
the shaded area is acceptable. Having the
fewest number of elbows is ideal, as they
tend to disrupt air movement. Using 45˚
elbows is preferable to using 90˚ elbows.
Also, a shorter vent system will perform
better than a longer one.
The vent restrictor controls the amount of
The vent restrictor controls the amount of
air moving through the vent pipe. Longer
vertical vent lengths necessitate greater
restriction; position 1 is open and position 5
is maximum restriction. Figure 30 shows the
vent restrictor settings required, relative to
the length of vent pipe. The vent restrictor
is located on the right side of the fireplace,
above the glass. Figure 31 shows the vent
restrictor handle and the holes that indicate
the different levels. To avoid injury, it is best
to make this adjustment when the fireplace is
cool or use welder’s gloves or oven mitts.
Note: 0,0 in Figure 30 represents a 90˚ bend
Note: 0,0 in Figure 30 represents a 90˚ bend
directly off the outlet of the unit, 38¾ inches
(985mm) for hard pipe and 41¼” (1048cm)
for flex pipe from floor, in all horizontal
instances.

NOTE: The total length of the vent
pipes can not exceed 30 feet (9.17 m).
Any combination of rise and run can be
used as long as it lays within the shaded
area (a total of three (3) 90° elbows or
six (6) 45° elbows can be used). In
addition to what is shown, if a 90°
elbow is used in the horizontal
plane, 3 feet (91.4 cm) must be
subtracted from the allowable
horizontal run (for each
45° elbow, 1½ feet must
be subtracted from the
allowable horizontal
run).
