Vertical Termination
A vertical vent system must terminate no less than 8’
(2.44m) and no more than 40’ (12m) above the appli-
ance flue collar. A restrictor plate (supplied) must be
used (where specified) in all vertically terminated vent
systems. NOTE: The restrictor plate supplied with
the vertical termination should be discarded. Install
restrictor plate according to recommendations in
Figure 10. A vertically terminated vent system must
also conform to the following criteria:
• No more than three 90° elbows may be used. 90°
elbow off back must be transition elbow.
• Two 45° elbows may be substituted for one 90°
elbow. No more than six elbows may be used.
• Vent must rise a minimum of 2 feet before offset is
used.
• Termination height must conform to roof clearance
as specified in Figure 11.
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.
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.
4. Adjust restrictor according to examples in Figure 10.
5. Install logs following log installation instructions.
