Vermont Casting SDDVRCEB Vertical Termination, Restrictor Plate Adjustment for Extended Pipe Runs

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.
