Hearthstone Quality Home Heating Products, Inc. ® Morgan Model 8470 15
EXCESSIVE DRAFT: Contact your dealer to
have a draft reading taken. Any draft in excess of 0.1 wc
requires a damper in the stovepipe. Some installations
may require more than one damper.
INAPPROPRIATE FUEL: Do not burn coal,
kiln dried lumber, wax logs or anything other than natural
cordwood.
OPERATOR ERROR: Make sure all the gaskets
are in good condition. Replace worn out or compressed
gaskets. Do not burn the Fireplace Insert with the front
door in the open position.
Monitoring the temperature of the surfaces is the best way
to determine if the Fireplace Insert is over-firing. If you
suspect that your Fireplace Insert is over-firing, contact
your dealer immediately. Damage done by over-firing
is not covered by your warranty. Results of over-firing
can include: warped or burned out internal parts, cracked
stones, discolored or warped external parts, and damaged
enamel.
NOTE: ANY SYMPTOMS OF OVER-FIRING
WILL VOID YOUR WARRANTY!!
MAINTENANCE
Do not over-fire the Fireplace Insert. (refer to page 14).
C REOSOTE F ORMATION A ND N EED F OR
R EMOVAL
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 Fireplace Insert with the primary air
control fully open for 35 - 45 minutes daily to burn out
creosote deposits from within the Fireplace Insert and the
venting system.
2. After reloading with wood, burn the
Fireplace Insert 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 Fireplace
Insert 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 Fireplace Insert.
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.
G
ASKETS
Gasket material should normally be replaced every two to
three seasons, depending on Fireplace Insert use. If the
door seal is loose, a new gasket will assure a tight seal
and improved Fireplace Insert performance. Contact your
dealer for a gasket kit that includes instructions and
gaskets for your Fireplace Insert.
The procedure for replacing gaskets on the glass is
reviewed below under “Glass”.
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.
G
LASS
Do not operate the Fireplace Insert with a broken door
glass. Do not abuse the front door by striking or
slamming.
When necessary, the glass can be cleaned with low
alkaline content commercial stove glass cleaners, which
