AUTION 

 

 

Over-firing means the stove is operating at temperatures 
above the recommended temperatures outlined above in 
the 

BURN RATE

 section.  Over-firing should be carefully 

avoided since it will cause damage to the stove.  
Symptoms of over-firing include short burn times, a 
roaring sound in the stove or stovepipe, and discoloration 
of the stovepipe. 
 
Over-firing can be caused by excessive draft, 
inappropriate fuel, and operator error.  Correct an over-
fire situation as follows: 
 

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 stove with the front, side or ash 
doors in the open position. 
 
Monitoring the temperature is the best way to determine if 
the stove is over-firing.  If you suspect that your stove 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, discolored or warped external parts, and 
damaged enamel. 

 

 

NOTE: ANY SYMPTOMS OF OVER-FIRING 

WILL VOID YOUR WARRANTY!!

SHES 

 

 
Ashes should be removed when the stove is cold.  Use 
protective fireplace gloves when the pan is warm.  
Exercise extreme caution when handling, storing or 
disposing of ashes. 
 
To remove ashes from the firebox, sift the ashes across 
the ash grate using a poker or other suitable implement.  
Remove the ashes by rotating the handle on the ash door 
counter-clockwise and sliding the ash pan carefully out.  
Dump the ashes as described below.  Re -insert the ash 
pan by pushing it in all the way.  Be sure that the ash pan 
has been pushed firmly into place.  Alternately, the ashes 
can be removed with a shovel through the side or front 
door.   
 
 
 

 
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.

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 
that may damage the chimney or even destroy the house.   
 
To prevent the buildup of creosote: 
 
 

1.  Burn the stove with the primary air control 

fully open for 30 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.
