TWO WEEKS: 
•   Inspect the chimney connector and chimney. Clean if 

necessary.

TWO MONTHS:
•   Inspect the chimney and chimney connector. Pay 

particular attention to the horizontal runs of chim-
ney connector, and the elbows. Clean the system if 
necessary.

•  Disassemble the chimney connector and take it 

outdoors for inspection and cleaning. Replace weak 
sections of connector.  

•   Inspect the chimney for signs of deterioration. Re-

pairs to a masonry chimney should be made by a 
professional mason. Replace damaged sections of 
prefabricated chimney. Your local Dutchwest dealer 
or a chimney sweep can help determine when re-
placement is necessary.

•   Thoroughly clean the chimney.

This wood heater contains a catalytic combustor, which 
needs regular inspection and periodic replacement for 
proper operation.  It is against the law in the United 
States to operate this wood heater in a manner incon-
sistent with operating instructions in this manual, or if 
the catalytic 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.
The combustor should be visually inspected “in place” 
for fly ash accumulation and physical damage three 
times per year.  Actual removal of the combustor is not 
recommended unless a more detailed inspection is war-
ranted because of diminished performance as outlined 
below.  
The refractory package housing the catalytic combustor 
should be inspected annually for a build-up of fly ash 
and cleaned if necessary.  This may be done during 
examination of the catalytic combustor.

There are two ways to evaluate the performance of 
your stove’s combustor.  
The first is to monitor the temperatures on the probe 
thermometer.  A properly-functioning combustor should 
operate  in the range of 800-1200

0

F. (430-650°C.).  

Combustor temperatures consistently less than 800

0

F. 

(430°C.) merit a closer examination of the combustor.
The second performance test is to observe the amount 
of smoke leaving the chimney — both when the com-
bustor has achieved “light-off”  and when it has not.  
Follow this simple two-step procedure:

• 

With a fire in the stove and the combustor properly 

activated by the closing of the stove damper to route  
smoke through it as described in the Operation Section, 
go outside and observe the smoke leaving the chimney.

• 

Then, open the stove damper and once again ob-

serve the smoke leaving the chimney. 
Significantly more smoke should be observed after the 
second step when the stove damper is open and ex-
haust is not routed through the combustor.  Be careful 
not to confuse smoke with steam from wet wood. Unlike 
smoke, steam disappears very quickly in air. 
If either of these tests indicates a problem, consider 
other possible factors as well.

In Spring or Fall, draft strength is less than in the middle 
of winter, and a related change in stove performance 
may result.  Small hot fires are a good solution to slug-
gish performance under these conditions.
Burning  “green” (insufficiently seasoned) wood will re-
sult in poorer performance than when burning properly 
seasoned fuel.  Was your fuel supply good and dry to 
start with, or has it changed?  You may have to run your 
stove hotter (more air) to achieve good performance if 
you are burning green or wet wood.  Also, any changes 
in operating routine should be considered at this time 
as a possible reason for changed performance.
Once you have ruled out any other possible causes 
for a decline in performance, you may proceed with an 
inspection of the catalyst.
