When installing the C72I / C72ID it may be necessary to add a restrictor in the firebox to control the
combustion and flame appearance. the exhaust restrictor ring kit is included in the manual bag, to install
the exhaust restrictor the safety screen assembly and glass door must be removed, see the Maintenance
and Service section [page 16 & page 17]. There are seven different restrictor sizes, make sure you
install the correct size. See Figure 49 for possible vent configurations and the corresponding restrictor
setting. Proper Install is crucial to a efficient fireplace burn and the best possible looking flame.
Note:
There are seven different restrictor sizes, they are marked with retangular holes which coincide
with the percentage of restriction.

The C72I / C72ID comes equipped with an Intake Blocker Plate installed on the far right side of the
firebox bottom behind the burner assembly. Depending on the vent configuration and fuel used it may
be necessary to adjust the position or completely remove the blocker plate to address overall flame
appearance and/or pilot turbulence.
To adjust the Intake Blocker Plate the firebox door, burner platform, and any panels or media on it, must
be completely removed from the firebox. The burner pan assembly and its media do not require removal.
Next, remove the two wing nuts (see Figure 51) holding the Blocker Plate in place and remove the plate
itself. The plate can then be re-installed in a different position, shown below, using the wing nuts or left
out entirely. Re-install the burner platform and firebox door to cofirm proper operation. If required, re-
adjust plate usage/positioning as necessary.
