are available from your local dealer. Never attempt to
clean the glass while the fire is burning or the glass is hot.
Most deposits can be cleaned by following the
instructions provided with the cleaner. To clean heavier
deposits, remove the top hinge and lift the door straight
up and off the Fireplace Insert (take care to save hardware
for reuse). Lay the door face down on a workbench or
table. Apply the cleaner to the glass and allow it to set for
a few minutes. By laying the door flat, it will allow the
cleaner to penetrate rather than running off the surface of
the glass. Wipe the cleaner off with a soft cloth.
Important: scratching or etching the glass will
weaken the integrity of the glass. Do not use a
razor blade, steel wool, or any other abrasive
material to clean the glass. Use low alkaline
content cleaners only.
The front door glass is a ceramic, shock-resistant glass,
made specifically for use in woodstoves. Do not use any
replacement glass other than the ceramic glass
manufactured and supplied for use in this woodstove.
Replacement glass is available through your local dealer.
The door glass should be replaced immediately if broken.
Contact your local dealer for replacement glass, which is
accompanied with instructions and everything needed for
the repair. If you replace the glass yourself, wear work
gloves and safety glasses.
The procedure for glass and glass gasket replacement is as
follows:
Refer to Figure 9.
1. Remove the door by removing the top hinge
screw and lifting the door straight up off the
bottom hinge.
2. Place the door face down on a flat, smooth
surface.
3. Apply penetrating oil to the screws.. Remove the
screws to separate the glass from the door.
4. Carefully lift the damaged glass from the door
and discard.
5. Replace the screws.
6. Install the door.
WARNING Do not use substitute materials when
replacing the glass or any door components. Only
authorized Hearthstone components should be used.

Exterior cast iron parts are either painted with black, high-
temperature stove paint or porcelainized with an enamel
finish in various colors.
Use black, high-temperature stove paint (satin black by
Stovebright) to touch up and maintain the original
appearance of painted cast iron. Use a damp sponge to
wipe clean. Dry the cast iron thoroughly to prevent
rusting.
Enamel castings can be cleaned with a standard glass
cleaner. With time and use, a very fine, subtle network of
crazed lines may appear seemingly beneath the surface of
the enamel. Crazing is a natural predictable process and
does not represent a flaw.
TROUBLESHOOTING
Your Heating Needs
Virtually all woodstove operators experience basic
common problems at one time or another. Most are
correctable and generally require only a minor adjustment
of the stove, installation, or operating technique. In cases
where weather conditions dramatically affect stove
performance, the problems are typically temporary and
solve themselves once the weather changes.
If you question whether your Fireplace Insert is producing
adequate heat, the best way to troubleshoot the problem is
to monitor the temperature of the stack. A 400 degree F
