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 loosen- ing 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 adjust- ment by the installer for optimum flame appearance. Optimum flame appearance is a flame that is not sub- ject to tall, dirty yellow flames producing soot or flames lifting off of the ember bed ports.
