DOOR ADJUSTMENT
In order for your wood fire to burn at its best efficiency, the door must provide a perfect seal with
the firebox. Therefore, the gasket should be inspected periodically making sure to obtain an air
tight fit. Air tightness can be improved with a simple latch mechanism adjustment. To increase the
pressure on the gasket, remove one washer (B). To reduce pressure on the door, when putting a
new door gasket for example, put two washers. To adjust:
1. Unscrew the two screws (A) holding the handle guide (B) and remove/add one spacer (B).
2. Reinstall the latch with the screws (A).
