Restrictor Location

MOST INSTALLATIONS REQUIRE RESTRICTORS for
improved fl ame picture and performance. The level of
restriction required depends on the vertical rise in the
venting system and, to a lesser degree, the horizontal
run and number of elbows.
The amount of restriction is based on laboratory tests.
The ideal restrictor position may vary slightly, especially
when the vent pipe length is near the limits of the
acceptable confi gurations for each type of restrictor.
The chart on the previous page shows the vent restrictor
positions required relative to the length of the vent pipe.
The fi replace is installed with the restrictor in the roof of
the fi rebox at the exhaust exit, above the fi rebox baffl e.
Note: Adjust restrictor position before liner
installation.
To access the restrictor:
1. Remove the baffl e (10 screws, fi ve on each side of the
baffl e).
2. Adjust the restrictor as per your installation
requirement set by the table on page 21.
