VENT CONFIGURATIONS AND RESTRICTOR SETTINGS:
Figures 31 shows the range of venting options, it shows possible vent congurations 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 36
NOTE: The total length of the vent pipes can
not exceed 32 feet (15.12 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, 1 feet
must be subtracted from the
allowable horizontal run).
shows the vent restrictor position required,
relative to the length of vent pipe. The vent
restrictor is located in the center of the
replace, above the glass. Figure 37 shows
the vent restrictor lever and the holes that
indicate the different levels. To avoid injury,
it is best to make this adjustment when the
replace is cool or use welder’s gloves or
oven mitts and a screw driver to adjust.
Note: 0,0 in Figure 36 represents a 90˚
bend directly off the outlet of the unit, 46
” (1175mm) for hard pipe and 49 ”
(1257mm) for ex pipe from oor, in all
horizontal instances.
