4. Glass Cleaning
• Frequency: As desired
• By: Homeowner
CAUTION
Handle glass assembly with care. Glass is breakable.
• Avoid striking, scratching or slamming glass
• Avoid abrasive cleaners
• Do not clean glass while it is hot
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 surfaces.
5. Cleaning Plated Surfaces
• Frequency: Prior to first burn and then as desired
• By: Homeowner
Clean all the fingerprints and oils from plated surfaces
BEFORE firing the appliance for the first time. If not
cleaned properly before lighting your first fire, the oils can
cause permanent markings on the plating.
After the plating is cured, the oils will not affect the finish
and little maintenance is required. Wipe clean as needed.
CAUTION
• Do not use polishes with abrasives. It will scratch
plated surfaces.

6. Inspect Firebrick
• Frequency: After each ash removal
• By: Homeowner
Replace the firebrick if they become crumbly and/or if there
is a 1/4 inch (6.35mm) gap between the bricks.
The firebox is lined with firebrick, which has exceptional
insulating properties. Do not use a grate; simply build
a fire on the firebox floor. Do not operate appliance
without firebrick.
1. After the coals have completely cooled, remove all old
brick and ash from unit and vacuum firebox.
2. Remove new brick set from box and lay out to the
diagram shown in the instructions that come with the
brick set or refer to the diagram on the service parts list
at the end of this manual.
3. Lay bottom bricks in unit.
4. Install rear bricks on the top of the bottom bricks. Slide
top of bricks under clip on back of firebox wall and push
bottom of bricks back.
5. Install side bricks. Slide top of brick under clips on side
of firebox and push the bottom of the brick until it is
flush with the side of the unit.
