When brown streaks are coming from the edge of the glass, it is time to replace the gasket around
the glass. The glass gasket should be self-adhesive. Follow the instructions in section «
6.1.4
Replacing the Glass or the Glass Gasket
» for installation. Always replace gaskets with genuine
ones. See «
Appendix 7: Exploded Diagram and Parts List
».
Do not abuse the glass door by striking or slamming shut. Do not use the insert if the glass is
broken.
6.1.2
DOOR ADJUSTMENT
In order for the insert to burn at its best efficiency, the door must provide a perfect seal with the
firebox. Therefore, the gasket should be inspected periodically to insure a good seal. The gasket
seal may be improved with a simple latch mechanism adjustment. To adjust the pressure on the
seal, unscrew the top and bottom bolts and move the plate forward or backward. To adjust the
angle of the door handle, unscrew the left and right bolts and raise or lower the mechanism.
6.1.3
REPLACING THE DOOR GASKET
It is important to maintain the gasket in good condition. After a year or more of use, the door
gasket will compress and become hard, which may allow air to leak. The condition of the door seal
can be verified by closing and latching the door on a strip of paper. The test must be performed all
around the door. If the paper slips out easily anywhere, it is time to replace the gasket.
