Maintenance; Monitoring Stove Temperatures; Creosote Formation And Need For Removal; Gaskets - HearthStone Heritage 8021 Owner's Manual

Ashes should be dumped from the ash drawer into a metal
container with a tight fitting lid. Do not place any other
items or trash into the metal container. Replace the lid onto
the container and allow the ashes to cool. Do not place the
ash disposal container on a combustible surface or vinyl
flooring, as the container will be hot!
Pending disposal, place the closed ash container on a
noncombustible floor or on the ground, well away from all
combustible materials. Ashes should be retained in the
closed container until all cinders have thoroughly cooled.
Ashes should NEVER be placed in wooden or plastic
containers, or in paper or plastic bags, no matter how long
the fire has been out. Coals within a bed of ashes can
remain hot for several days once removed from the firebox.

ONITORING TOVE
Monitor the stove temperatures with a stove thermometer
(available from your dealer) placed on the top center stone
of the stove. The thermometer could read as high as
500°F(260°C) on High Burn and 200-300°F(93-149°C) on
low burn. Maintaining temperatures in excess of
600°F(316°C) will cause the stones to crack and other
damage to the stove.
Do not over-fire the stove. (refer to page 18).
Damage done by over-firing will void the warranty.

REOSOTE ORMATION
When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture to
form creosote. These creosote vapors condense in the
relatively cool chimney flue of a slow-burning fire. As a
result, creosote residue accumulates on the flue lining.
When ignited, this creosote makes an extremely hot fire,
which may damage the chimney or even destroy the house.
When burning wood, the chimney connector and chimney
should be inspected at least once every two months during
the heating season to determine if a creosote buildup has
occurred.
To prevent the buildup of creosote:
1. Burn the stove with the primary air control
fully open for 35 - 45 minutes daily to burn out creosote
deposits from within the stove and the venting system.

2. After reloading with wood, burn the stove with
the primary air control fully open for 20 to 30 minutes.
This manner of operation ensures early engagement of the
secondary combustion system which, when engaged,
minimizes creosote buildup in the chimney.
The stovepipe connector and chimney should be inspected
at least monthly during the heating season to determine if a
creosote build-up has occurred. If a creosote residue
greater that 1/4" (6 mm) has accumulated, it should be
removed to reduce the risk of a chimney fire.
If your glass is remaining dirty, your operating
temperatures are low; therefore, there is a higher risk of
creosote buildup.
The venting system must be inspected at the stove
connection and at the chimney top. Cooler surfaces tend to
build creosote deposits quicker, so it is important to check
the chimney at the top (where it is coolest) as well as from
the bottom near the stove.
Accumulated creosote should be removed with a cleaning
brush specifically designed for the type of chimney in use.
A certified chimney sweep should be used to perform this
service. Contact your dealer for the name of a certified
chimney sweep in your area (your dealer may be a certified
sweep!).
It is also recommended that before each heating season the
entire system be professionally inspected, cleaned and
repaired, if necessary.

ASKETS
Gasket material should normally be replaced every two to
three seasons, depending on stove use. If the door seal is
loose, a new gasket will assure a tight seal and improved
stove performance. Contact your dealer for a gasket kit that
includes instructions and gaskets for your stove.
The procedure for replacing gaskets on the glass is
reviewed on page 20.
To replace door gaskets, first remove the old gaskets with a
utility or putty knife. Clean all gasket channels with a wire
brush. Apply gasket cement to the channels and push the
new gasket into place without stretching the gasket
material. The door should be shut immediately to fully
press the gasket into place and assure a positive seal.
We require the use of the following gaskets:
DOOR: 67" (170 cm) Length, 3/8" (9.5 mm) Diameter,
