VENT CONFIGURATIONS AND RESTRICTOR SETTINGS:
Figures 20 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.

Figure 20. Possible Vent Configurations
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 20 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 21 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 20 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.
