Then, open the stove damper and once again 

check the smoke leaving the chimney. Significantly 
more smoke should be seen when the stove damper is 
open and exhaust does not pass through the combus-
tor. Be careful not to confuse smoke with steam from 
wet wood, however. Steam dissipates in the air quickly; 
smoke does not. 
If this test indicates a problem, consider other possible 
factors as well, such as the time of year or a change in 
the quality of your fuel. In spring and fall, draft is weaker 
than it is in colder winter weather, and fires can burn 
sluggishly. Small, hot fires are a good solution under 
these conditions.
Burning  “green” (insufficiently seasoned) wood will re-
sult in poorer performance than when burning properly 
seasoned fuel. You may have to run your stove hotter 
(more air) to achieve good performance with green or 
wet wood.  
Also, consider any changes in your operating routine.
Once you have ruled out any other possible causes for 
a decline in performance, you may inspect the combus-
tor.

1.  Release the hood from the fireback by swinging the 

hood upward and then sliding it to either side. (Fig. 
34)   

2.  Using a flashlight, and a mirror if necessary, exam-

ine the combustor. If no fly ash or damage is visible, 
the inspection is complete and you may replace the 
hood. If further examination or cleaning is necessary, 
go to Step 3.   

This wood heater contains a catalytic combustor, which 
needs periodic inspection and replacement for proper 
operation. In the United States it is against the law to 
operate this wood heater in a manner inconsistent with 
the operating instructions in this manual, or if the cata-
lytic element is deactivated or removed. 
Under normal operating conditions, the catalytic com-
bustor should remain active for two to six years (de-
pending on the amount of wood burned). However, it 
is important to monitor the combustor periodically to 
ensure that it is functioning properly, as well as to deter-
mine when it needs to be replaced.  A non-functioning 
combustor will result in a loss of heating efficiency, and 
an increase in creosote and emissions.
Inspect the combustor “in place” for fly ash accumula-
tion and physical damage three times per year. Do not 
remove the combustor unless a more detailed inspec-
tion is warranted because of diminished performance 
as outlined below.  
The refractory package that houses the catalytic com-
bustor should be inspected annually for a buildup of fly 
ash and cleaned if necessary. This may be done when 
you examine the combustor.

The best way to evaluate the performance of your 
Encore’s combustor is to observe the amount of smoke 
leaving the chimney — both when the combustor has 
achieved “light-off”  and when it has not. Follow these 
steps:  

 

 

• 

With a fire going and the combustor properly ac-

tivated, with the damper closed to route smoke through 
it as described in the Operation Section, go outside and 
observe the smoke leaving the chimney.

3.  Release the fireback by prying the left and right 

wedges upward. (Fig. 35) 

4.  Swing the fireback forward and up to remove it from 

the stove. (Fig. 36)

5.  Remove the catalytic combustor’s refractory access 

cover, then remove the combustor.
