 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. 

Do not over-fire the Fireplace Insert. (refer to page 16). 
 

 
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. 
 

 
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. 
 

 
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
