Restrictor Plate Adjustment

for Extended Pipe Runs
The Stardance 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. (Fig. 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.
