An exhaust restrictor is built into exhaust vent at the rear of the fireplace. It is used to adjust the flow rate of
exhaust gases. Depending upon vent configuration, you may be required to adjust the restrictor. The
charts for acceptable vent configurations detail the correct vent restrictor position. The restrictor is
accessed from inside the firebox (remove the glass to gain access). To adjust the restrictor, remove the
nut and bolt holding the restrictor in position, rotate the restrictor to the correct position, then replace the
nut and bolt to secure (see ).
