The Catalytic Element - Vermont Castings Defiant FlexBurn 1975 Installation And Operating Manual

Defiant FlexBurn 1975 Non-Catalytic / Catalytic Wood Burning Stove
® ®
Clean the chimney connector by disconnecting the sec-
tions, taking them outside, and removing any deposits with
a stiff wire brush. Reinstall the connector sections after
cleaning, being sure to secure the joints between individual
sections with sheet metal screws.
If you cannot inspect or clean the chimney yourself, con-
tact your local Vermont Castings dealer or a professional
chimney sweep.
Maintenance Schedule
The Stove
DAILY:
•
Clear any ash build-up from around the air holes and
combustion flow path in the lower fireback.
•
Ashes should be removed before they reach the top of
the ash pan. Check accumulation at least once a day.
•
Keep the area around the stove clear of any combustible
materials such as wood, furniture or clothing.
TWO MONTHS:
•
Check door handle to be sure it is working properly.
Gasketing becomes compressed after a period of time.
Adjust handle tightness if necessary.
•
Check leg bolts and heat shield screws; tighten if nec-
essary.
ANNUAL SPRING CLEANING:
•
Check gasketing for wear, and replace if necessary.
•
Remove ashes from the ash pan and replace with a
moisture absorbing material (such as kitty litter) to keep
the interior of the stove dry.
•
Clean the dust from the inner sides of bottom, rear or
pipe heat shields if your stove is equipped with them.
Clean surfaces are better heat reflectors than dirty sur-
faces.
•
Touch up the black paint.
•
Inspect for and remove ash build-up behind the com-
bustion package. This should be done in conjunction
with annual cleaning of the chimney connector. Inspect
the passage behind the combustion package (a mirror
will be helpful) and vacuum away ash using a flexible
vacuum hose inserted in the passage. (Fig. 47)
The Chimney Connector
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 chimney
connector, and the elbows. Clean the system if neces-
sary.

ANNUAL SPRING CLEANING:
•
Disassemble the chimney connector and take it outdoors
for inspection and cleaning. Replace weak sections of
connector.
•
Inspect the chimney for signs of deterioration. Repairs to
a masonry chimney should be made by a professional
mason. Replace damaged sections of prefabricated
chimney. Your local Vermont Castings dealer or a chim-
ney sweep can help determine when replacement is
necessary.
•
Thoroughly clean the chimney.

he Catalytic Element
T
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 op-
erate this wood heater in a manner inconsistent with the
operating instructions in this manual.
Under normal operating conditions, the catalytic combus-
tor should remain active for two to six years (depending
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 determine 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.
Inspection and Cleaning
Inspect the combustor for fly ash accumulation and physi-
cal damage three times per year. Clean the combustor as
needed.
The refractory package that houses the catalytic combustor
should be inspected for a buildup of fly ash and cleaned
if necessary. This may be done when you examine the
combustor.
