Some vent configurations may create excess draft within the fireplace. Excess draft can cause issues such as a
rapid, or "nervous" flame picture, undesirable flame color, or pilot lifting which may prevent the fireplace from
staying lit. In these circumstances it may be necessary to install the flue restrictor in the venting system. It is
permissible to install this restrictor at the vent cap should the venting system already be installed. Secure the
restrictor plate with the included #10 sheet metal screws.
GEMINI 48 flue baffle kit
Certain vent configurations for the GEMINI 48, particularly those with a significant amount or vertical in relation
to the amount of horizontal vent pipe, may cause the flame to be unbalanced, or biased toward the flue outlet
side of the fireplace. Installation of this flue baffle will help to resolve this issue. It may be necessary to use this
restrictor on its own, or in addition to the AURORA flue restrictor kit shown above. This flue baffle kit snaps into
the fireplace as shown below.
