Exhaust restrictor Instructions
Exhaust restrictors are recommended for these verti-
cally terminated products which have excessive draft.
Exhaust restrictors will compensate for high draft, and
restore visual flame height. If the vent configuration has
a total vertical of 12 ft. (3.7 m), an exhaust restrictor may
be needed. The exhaust restrictor is located in the appli-
ance manual bag.
Note:
Remove center tab in exhaust restrictor for vent
configuration with over 20 ft. (6.0 m) of vertical.
See Figure 4.13.
Note:
Remove inner heat shield, if installed.
1. Install the exhaust restrictor over the center of the ex-
haust outlet in the firebox. See Figure 4.13.
2. Center the exhaust restrictor in the open end of the
exhaust outlet and secure through the slots on the ex-
haust restrictor with the two 1/4 in. self tapping screws
provided in the appliance manual bag.
3. Reinstall top refractory.
Note:
If installing a vertical vent/termination off the top of the
appliance, the optional exhaust restrictor may be needed.
