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. (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
• Remove the screw in the back wall of the firebox.
• Install restrictor plate as shown in Figure 9 with cut out
on left side. Secure with adjustment screw.
• Measure from center of screw to top edge of diverter
(Figure 9) to adjust plate according to guidelines in
Figure 10.
• Tighten attachment screw.
• Install logs following log installation instructions.
