7.3 Vent Restriction
Burner flame appearance and characteristics are affected by altitude,
fuel quality, venting configuration, and other factors. To achieve
desirable flame appearance, the vent exhaust may be restricted by
the restrictor plate (included in components packet) and/or adjust
the built-in restrictor located in the fireplace baffle.
The restrictor plate is shipped with all inner rings intact, and when
installed, provides the most vent restriction. There are (2) inner rings
that can be knocked out. The innermost ring knocked out will create
less restriction, and the outer most ring knocked out will create the
least amount of restriction.
Follow
for restrictor plate installation before attaching
venting
, or
through the baffle restrictor if venting is already attached.
If you are adjusting the baffle restrictor, loosen the (2) thumb screws
to adjust the setting to achieve desired flame appearance.
For vent restriction recommendations and adjustments, see section
