TROUBLESHOOTING 
 

 

PAGE 21 

SMOKES OUT FUEL DOOR WHEN OPEN (see 

)

 

1.  The primary air control is closed.  
2.  The chimney is too cool. Set the primary air control 

on "HIGH" with the bypass damper control "OPEN" 
for a few minutes before opening the fuel door. 

3.  Excess creosote will not only restrict your draft but it 

will create a risk of a creosote fire. Strictly adhere to 
maintenance requirements as outlined in this man-
ual. If excess creosote has built up on the inside of 
the firebox sides and door, burn a small hot fire at in-
tervals that are more frequent with air control on 
HIGH for a few minutes. 

4.  Deposits may have built up in the chimney and are 

restricting the draft, or the spark arrester on top of 
the chimney may be plugged. 

5. Chimney diameter too large or too small to provide 

adequate draft.   

6.  The house is too airtight (usually takes 20 to 30 min-

utes for problem to appear as stove lowers air pres-
sure in house).  Crack a window open or provide an 
outside source of air near stove. 

7. Insufficient vertical height to chimney to achieve 

adequate draft. 

8.  The combustor is plugged from engaging too soon 

(remove combustor and clean, see Maintenance 
section, page 20). 

 

DOES NOT PRODUCE ENOUGH HEAT (

)

 

1.  Using green or insufficiently cured wood. 
2. Excessive draft. 
3. High ceilings (heat rises quickly, but can be recircu-

lated by a well-placed ceiling fan with a win-
ter/summer switch). 

4. The area to heat, is too large (square foot heating 

estimates are based on "average" climates and 
home design). 

5.  There's an obstruction in the chimney. 
6. The chimney or chimney cap is restricted by creo-

sote preventing enough draw to sustain a "HIGH" 
heat rate. 

7.  Combustor light off has not occurred. 
 

DOES NOT MAINTAIN A FIRE

 

(

)

 

1.  Soft wood does not burn as long or as well as sea-

soned hardwood resulting in a short burn time. 

2.  Wood size too small. Burns at too rapid a rate. 
3. The gasket seal on the fuel door, ash drawer or 

glass is leaking air. Repair or replace it if necessary. 

4.  There is an obstruction in the chimney. 
5.  The stove was not up to normal operating tempera-

ture before the bypass damper control was pushed 
closed. 

6. Excessive draft. 

 
BACKPUFFING (

)

 

1.  Downdraft in the chimney (may need a special 

wind cap). 

2.  The catalytic combustor is too hot  (avoid burn-

ing soft, pitchy woods, or large amounts of small-
diameter wood). 

3  The house is too air tight (ventilation is needed). 
4.  Insufficient vertical height to chimney to achieve 

adequate draft. 

 
ODORS

 

1.  Creosote accumulation in firebox (brush out on 

next cleaning). 

2.  Chimney downdraft when stove is not operating 

(close primary air control).    

3.  Catalytic combustor not functioning. 
4.  Paint curing on first several burns. 
 

DIRTY GLASS (

)

 

1.  Poor draft conditions. 
2.  Long burn periods at low draft settings. 
3.  Burning wet, pitchy or spongy wood. 
4.  Poorly arranged logs (too close to glass). 

 

 

 

(

) DRAFT PROBLEMS

:

 IF INSTALLING INTO A 

LARGER FLUE, IT MAY BE NECESSARY TO 
USE A FULL LENGTH LINER TO ACHIEVE ADE-
QUATE DRAFT FOR THE APPLIANCE. A DRAFT 
GAUGE SHOULD READ A MINIMUM OF .05" 
W.C. (INCHES WATER COLUMN) NOT TO EX-
CEED .07" W.C. FOR OPTIMUM PERFORMANCE

 Draft Requirements,
