Exhaust restrictor Instructions
1. Locate the two pilot holes located in the inside firebox
heat shield as shown in Figure 7.6.
2. Center the exhaust restrictor such that the through
holes in the vent restrictor align with the pilot holes in
the heat shield.
3. Use (2) 1/2 in. (13 mm) self-piercing screws to secure
vent restrictor to firebox heat shield. See Figure 7.7.
Exhaust restrictors are recommended for these vertically
terminated products which have excessive draft. Exhaust
restrictors will compensate for high draft. and restore vi-
sual flame height. If the vent configuration has a total ver-
tical of 15 ft. - 44 ft. (4.6 m - 13.4 m), an exhaust restrictor
may be needed. The exhaust restrictor can be located in
the appliance manual bag.
