Glass Door

6.3.1 Cleaning
Under normal conditions, the door glass should stay relatively clear. If the firewood is dry
enough and the operating instructions in this manual are followed, a whitish, dusty deposit will
form on the inner surface of the glass after a week or so of use. This is normal and can be easily
removed when the heater is cold by wiping with a damp cloth or paper towel and then drying.
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 stove 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.
6.3.2 Replacement
The glass used is a ceramic glass, 5/32" (4 mm) thick,12 ½" x 11 ⅛" (319 mm x 283 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 (G):
1. Remove the door (H) and place it face-down
on something soft.
2. Remove the glass retainers (E) held in place by
the screws (D).
Remove the frames (F).
3.
4. Remove the glass. If it is damaged install a new
one in place. The replacement glass must have
a gasket all around.
5. 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.
