Other gaskets form seals between non-moving parts, but these are not subject to the same wear and dete- rioration as gaskets on moving parts. It is unlikely that you will ever need to replace these gaskets unless the involved parts are disassembled and then put back together. In any event, this is a job that should be done only by qualified service personnel.

Replace Damaged Door Glass Immediately

Do not operate the WinterWarm with a damaged glass (or screen) cassette. Use the following procedure for cassette replacement.

NOTE: Replace glass only with CFM Corporation high temperature ceramic glass, available from your Ver- mont Castings’ Authorized Dealer.

•Open the door and loosen the two retaining clips, one at each upper corner, which hold the cassette to the door frame. Swing the clips out of the way. Tilt the cas- sette away from the door frame and lift up. Use caution when handling a cassette that contains broken glass.

•Examine the gasket that seals the cassette to the door frame. Replace if necessary with gasket obtained from your local Vermont Castings’ Authorized Dealer. See the directions for gasket replacement on page 9.

•Check the channel at the bottom of the door frame, and clear away debris if necessary.

IMPORTANT: The glass used in your WinterWarm is coated with a special material on one side that reflects heat back into the fire chamber. Before replacing a glass cassette that has been removed, examine the metal frame. One side has smooth, mitered corner joints; the other side has rough weld marks.

To install the glass correctly, the smooth mitered corners must be facing the gasket and the rough weld marks must be positioned toward the fire chamber.

•Secure the clips, being careful not to over-tighten. Be sure the cassette is firmly seated against the gasket. Close the door gently to confirm that the clips have been properly positioned. It is possible for the glass to be damaged if the clips have been installed incorrectly and the door is closed with force.
