READ THE INSTRUCTIONS FOR THIS UNIT
CAREFULLY.
Maintaining Catalytic Conditions -During the start-up of
a cold stove, a medium stove, a medium to high airseting
must be maintained for about 20 minutes. This ensures
that the stove, catalyst, fuel, and chimney area all at proper
operating temperature. Even though it is possible to have
smoke temperature reach 600 degrees within two or three
minutes after af ire is started, the combustor and the
chimney are not yet warm enough. At the end of the burn
cycle; it’s possible that the amount of buring charcoal
mightnot provide sufficient temperatures for the catalyst.
During the refueling, we recommend that the stove be fired
hard for at least 10 minutes to ensure that the satalyst and
chimney are properly warmed up. If you have a long or
large diameter chimney, or if it is very cold outside, run the
stove on high for a longer period.
W henever loading the stove, KEEP THE BYPASS OPEN!
NEVER remove the combustors to clean them. If there
seems to be excessive fly ash on the combustors, use the
blower side of your vacuum claener to blow ash out. Be
cerain you never vacuum ash into your vacuum cleaner.
Always replace the mixers after brushing the combustors.
Combustor Life and Replacement - Sierra uses only
“12,000 Hour Long Life Combustors.” The combustor will
still be functioning at 7-% of its effectiveness after 12,000
hours of use. Depending on the frequency of stove use, it
will last for four to twelve years before needing
replacement.
VI. CATALYTIC INSPECTION AND REPLACEMENT
It is important to periodically monitor the operation of the
catalytic combustors to ensure they are functioning
properly and to determine when they need to be replaced.
A non-functioning combustor will result in a loss of heating
efficiency, and an increase in creosote and emissions.
• The combustors should be visually inspected at least
three tim es during the heting seson to determine if
physical degradation has occurred. Rem ove the catalytic
cassette by loosing the two 3/8" nuts. Look for cracks,
cell blockage, excessive fly ash and general
deterioration.
You can get an indication of whether the catalyst is working
by comparing the amount of smoke leaving the chimney.
1. Leaving the bypass open, go outside and observe the
amount of smoke leaving the chimney.
2. Close the bypass, go outside and observe the amount of
smoke leaving the chimney.
Significantly more smoke should be seen when the
bypass is open and the exhaust is not being routed
through the combustors. Be careful not to confuse
smoke with steam from wet wood.
After inspecting the combustors and it it determined that
they are defective, they must be replaced. Read the
catalytic warranty information carefully.
3. Inspect the bypass gasket regularly. A bright light or
flashlight is useful for locating any areas that are not
sealed.
