Figures 28 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 air
moving through the vent pipe. Longer vertical
vent lengths necessitate greater restriction;
position 1 is open and position 5 is maximum
restriction. Figure 28 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
29 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 28 represents a 90˚ bend
directly off the outlet of the unit, 46” (1169 mm)
from floor. This is for all horizontal instances
except when using Selkirk and having less
than a 4 feet (1.22 m) rise and 8 feet (2.44 m)
horizontal offset. In this case, a 1 foot rise must
be added below the 90˚ bend.
