Glasses
The cookstove has two glasses to maintain. The combustion chamber glass has a gasket while
the furnace does not.
6.6.1
Cleaning
Under normal conditions, the door glass should stay relatively clear. If the firewood is dry enough and the
operating instructions in this guide 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 stove 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 stove. 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.
The glass gasket should be self-adhesive. Always replace the gasket with a genuine one.
