Restrictor Plate Adjustment
for Extended Pipe Runs:
This stove is shipped with a restrictor plate in the Parts Bag.
Adjustments can be made by loosening the adjustment
screw to allow the restrictor plate to slide up or down.
(Figure 9) A guide for usage is shown in Figure 10.
NOTE: Some installations may require some adjustment by
the installer for optimum flame appearance. Optimum flame
appearance is a flame that is not subject to tall, dirty yellow
flames producing soot or flames lifting off of the ember bed
ports.
Restrictor Plate Adjustment:
1. Remove the logs if installed.
2. Remove the adjustment screw in the back wall of the
firebox.
3. Install restrictor plate as shown in Figure 9 with angle
on plate on the top right side. Secure with adjustment
screw.
