Restrictor Plate Adjustment
This stove is shipped with a restrictor plate in the Parts
Bag. Adjustments can be made by loosening the adjust-
ment screw to allow the restrictor plate to slide up or down.
(Fig. 9) A guide for usage is shown in Figure 10.

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.
