INSTALLATION OF FLUE RESTRICTOR:
Flue Restrictors are necessary to keep the
fireplace running at its intended efficiency. They
are also required to counteract the effect that
taller vertical vent runs may have on the appliance.
The additional venting action that tall vertical vent
systems may have can result in poor pilot and/
or burner operations and possibly nuisance shut
downs. Generally, the vent restriction may be less
than what is shown in the vent chart, but not greater.
The vent restrictor size is shown in percentages,
meaning that a 40% restrictor restricts the vent
40% from its fully un-restricted vent size.

of the appropriate Restrictor.
5) Using the two (2) ¼” T-20 screws provided with
the restrictor, fasten the Restrictor into the Flue
Outlet as shown in Figures 25 & 26. Make sure
the diagonal holes line up with the diagonal holes
located in the Flue Outlet Box Use a powered
driver to drive the screw in. Be careful not to
over-torque the screw and strip the threads.
6) Re-install the Light Covers, Firebox Liners, Burners and log sets and the Glass Door.
7) Run the unit for ½ hour to check for proper operations and flame appearance.
