EMOVAL
When wood burns slowly at low temperatures, 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, inspect the chimney
connector and chimney at least once every two
months during the heating season to determine if
there is a creosote buildup.
T
O 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 that minimizes creosote buildup in the
chimney.
3. If a creosote build-up occurs, inspect the
stovepipe connector and chimney more often, at
least monthly during the heating season to
monitor the accumulation. If a creosote residue
greater that 1/4" (6 mm) accumulates, remove it
to reduce the risk of a chimney fire.
4. If your glass always remains dirty, your
operating temperatures are too low or your wood
is wet; therefore, there is a higher risk of
creosote buildup.
5. Inspect the venting system at the stove
connection
and
at the chimney top. Cooler
surfaces tend to build creosote deposits faster,
so it is important to check the chimney at the top
(where it is coolest) as well as from the bottom
near the stove.
6. Remove accumulated creosote with a cleaning
brush specifically designed for the type of
chimney in use. Use a certified chimney sweep
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!).
7. We recommend that before each heating
season
you
have
the
entire
system
professionally inspected, cleaned and repaired,
if necessary.

ROCEDURE
:
1. Open the door and remove the push nut from
the upper hinge pin, and remove the pin.
2. Tilt the top of the door outward, and then lift the
door up off the lower pin. The door weighs 81
pounds (37 kg)
– so use a helper if necessary.
3. Ensure the brass washer remains in place on
the lower pin.
4. Place the door face down on a padded work
surface. Use two rolled up towels, or similar,
under the door to stabilize the curved door
during maintenance.
5. When reinstalling the door, use a new push nut
on the upper hinge pin.

ASKETS
Replace door gasket material every two to three
seasons, depending on stove use. If the door seal
leaks, a new gasket will ensure a tight seal and
improve stove performance.
We recommend you only use Hearthstone Hase
Collection replacement gaskets and adhesive when
you need to replace your door gasket. Contact your
dealer for a gasket kit that includes instructions,
adhesive, and the gasket for your stove.

ROCEDURES
:
1. To replace the door gasket, remove the door
from the stove (see door removal instructions
above), and remove the door’s side plates. Pull
off the old rope gasket. Carefully remove any old
gasket material and adhesive with a small
screwdriver, or cold chisel and a hammer. Clean
all gasket channels with a small wire brush if
necessary.
2. Vacuum the inside of the door as required.
Loosely re-
attach the door’s side plates.
