MANUAL INSTALLATION AND OPERATION WFP-75 8411 ENGLISH
OF 40)
When the fireplace runs at a low combustion rate, light brown stains may form, especially in the
lower corners of the glass. This indicates that the fire has been smoky and some of the smoke
has condensed on the glass. It also indicates incomplete combustion of the wood, which also
means more smoke emissions and faster formation of creosote in the chimney.
The deposits that form on the glass are the best indication of the fuel quality and success in
properly using the fireplace. These stains can be cleaned with a special wood fireplace glass
cleaner. Do not use abrasive products to clean the glass.
The goal should be having a clear glass with no brown stains. If brown stains appear regularly
on the glass, something about the fuel or the operating procedure needs to be changed. When
brown streaks are coming from the edge of the glass, it is time to replace the gasket around the
glass. Always replace the gasket with a genuine one.
6.2.2 Replacement
The glass used is a ceramic glass, 5/32" (4 mm) thick, 24 ⅜" x 12 ⅝" (620 mm x 321 mm),
tested to reach temperatures up to 1400º F. If the glass breaks, it must be replaced with one
having the same specification. Tempered glass or ordinary glass will not withstand the
high temperatures of this unit.
To remove or replace the glass:
1. Remove the door from its hinges and lay it on a soft, flat surface.
2. Remove the gasket, the screws, the retainers and the metal frames.
3. Remove the glass. If it is damaged install a new one in place. The replacement glass must have a
gasket all around (see procedure below).
4. Reinstall the glass, being careful to centre the glass in the door and not to over-tightening the
retaining screw.
The two main causes of broken door glass are uneven placement in the door and over-
tightening the retaining screws.
