Cleaning
WARNING: DO NOT CLEAN THE UNIT WHEN HOT.
The unit should receive regular cleaning on, under,
and around the insert to prevent the buildup of dust
and lint. You can clean the exterior surfaces of the
unit 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,
or enamel when the residue of the cleaners or
polishes is exposed to heat. Excessive buildup of
dust, spider webs, or room air contamination will
cause odors when the stove is hot.
Monthly (or as needed):
Glass Cleaning
As fuel gas may contain some impurities and
moisture; 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.
Do not abuse, or strike the glass.
WARNING: DO NOT OPERATE THIS APPLIANCE
WITH ANY GLASS PANEL REMOVED, CRACKED,
OR BROKEN. DO NOT SUBJECT ANY GLASS OR
ITS FRAME TO ABUSE, SUCH AS STRIKING OR

Clean Firebox, Blower, Pilot, & Burner
Assembly
The firebox and its components require 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
façade and glass (see pages 32 and 18 respectively,
for
Façade
Removal
and
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, baffles, 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 33.
Check to ensure a proper flame is burning from each
burner port. The pilot flame should be burning
properly as shown on
page 34
.
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, pipe cleaner, or vacuum cleaner.
If the pilot flame height needs adjustment, it should
be adjusted by qualified service personnel as
described on page 3334.
If cleaning the convection blower
– also remove the
baffle panels (see page 29) and the burner (see
page 31).
