Cleaning
WARNING: DO NOT CLEAN THE UNIT WHEN HOT.
The unit should receive regular cleaning on, under,
and around the stove to prevent the buildup of dust
and lint. The exterior surfaces of the unit can be
cleaned using soap, water, and a soft cloth. Do not
use abrasive or chemical cleaners and take care not
to scratch the glass or enamel finish (if so equipped)
when cleaning the unit. The use of chemical wax
based cleaners or polishes are not recommended
due to the potential for discoloration of the castings,
stones or enamel when the residue of the cleaners
or polishes is exposed to heat. Excessive buildup of
dust, spider webs, or room air contamination may
cause odors when the stove is hot.
Monthly:
Glass Cleaning
As fuel gas may contain some impurities; it will be
necessary to clean the inside of the glass
occasionally. Do not use abrasive cleaners.
Scratching the glass will weaken the integrity of the
glass.
Do not clean the glass when hot!
Allow the
glass to cool and apply a mild window cleaning fluid.
Special gas appliance window cleaner is available
from your local Hearthstone dealer.
WARNING: DO NOT OPERATE THIS APPLIANCE
WITH THE GLASS PANEL REMOVED, CRACKED,
OR BROKEN. DO NOT SUBJECT THE GLASS OR
ITS FRAME TO ABUSE, SUCH AS STRIKING OR
BENDING. REPLACEMENT OF THE GLASS
PANEL SHOULD BE DONE BY A LICENSED OR
QUALIFIED SERVICE PERSON.

If the venting system is disassembled for any
reason, re-install per the instructions provided in the
venting section of this manual.
Annually:
Clean Firebox, Pilot, & Burner Assembly
The firebox requires periodic cleaning to prevent the
accumulation of dust, lint, and other debris. To clean
the firebox, set the switch to the “OFF” position, and
turn off the gas supply to the valve. When the unit is
cool, remove the front panel and glass (see page 15
for Firebox Access instructions) and carefully
remove the decorative ceramic log set, taking care
not to damage the logs or chip the enamel cast iron.
Remove all ember material. Clean the firebox baffle,
ceramic burner, and carefully vacuum the entire
surface of the log set with a soft brush attachment.
Thoroughly vacuum the ports (holes) along the top
of the burner, and the pilot assembly.
With the decorative ceramic logs out of the firebox,
reseal the firebox and briefly light the unit according
to the lighting instructions described on page 34.
Check to ensure a proper flame is burning from each
burner port. The pilot flame should be burning
properly as shown in Figure 17.
NOTE: Do not operate the unit for more than
1-2 minutes without the log set in place. Turn
the unit off by setting the switch to “OFF”,
and turning off the gas supply to the valve.
Allow the unit to cool.
Check and clean any burner ports that are not
burning, or not burning properly. Clean burner ports
using a soft brush or vacuum cleaner. If the pilot
flame height needs adjustment, it should be adjusted
by qualified service personnel as described on page
34.
Complete the cleaning procedure by carefully
placing the log set within the firebox as described on
page 28. Reattach the glass and front panel to seal
the firebox. Turn on the gas, light the unit and check
for proper operation. Flame patterns should look
similar to the flames in Photo 38. Regularly check to
ensure the area around the Tucson is kept free from
combustible materials, gasoline, and other
flammable vapors and liquids. Check that the flow of
combustion and ventilation air is not obstructed.
