4. Glass Cleaning
• Frequency: As desired
• By: Homeowner
Clean glass with a non-abrasive glass cleaner. Abrasive
cleaners may scratch and cause glass to crack. If the
deposits on the glass are not very heavy, normal glass
cleaners work well. Heavier deposits may be removed by
using a damp cloth dipped in wood ashes or by using a
commercially available oven cleaner.
After using an oven cleaner, it is advisable to remove any
residue with a glass cleaner or soap and water. Oven
cleaner left on during the next firing can permanently stain
the glass and damage the finish on metal surfaces.
A portion of the combustion air entering the firebox is
deflected down over the inside of the door glass. This
air flow "washes" the glass, helping to keep smoke from
adhering to its surface.
When operated at a low burn rate, less air will be flowing
over the glass and the smokey, relatively cool condition of a
low fire will cause the glass to become coated.
Operating the appliance with the Burn Rate Air Control and
Start-Up Air Control all the way open for 30-45 minutes
should remove the built up coating.
CAUTION
• Do not use polishes with abrasives. It will scratch
plated surfaces.
