VENT CONFIGURATIONS AND RESTRICTOR SETTINGS:

NOTE: The total length of the vent

30' (9.17m) 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, 11⁄2 feet must be subtracted from the allowable horizontal

run).

Figure 25. Possible Vent Configurations

Figures 25 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 25 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 26 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 25 represents a 90˚ bend directly off the outlet of the unit, 383⁄4 inches (985mm) for hard pipe and 411⁄4” (1048cm) for flex pipe from floor, in all horizontal instances.
