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 necessary.
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
chimney sweep can help determine when replacement
is necessary.
• Thoroughly clean the chimney.

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
necessary.
•
If installed:
Inspect the combustor for fly ash accumulation
and physical damage. Clean the combustor as needed.
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 surfaces.
• Touch up the black paint.
• Inspect for and remove ash build-up behind the combustion
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, Figure 3.7.

CAUTION
!
BURN UNTREATED WOOD ONLY. OTHER MATERIALS
SUCH AS WOOD PRESERVATIVES, METALS, FOILS,
COAL, PLASTIC, GARBAGE, SULPHUR, OR OIL, MAY
DAMAGE THE CATALYST.
The Dauntless FlexBurn
®
is designed to burn equally well
with or without a catalytic combustor (Part #SRV8346-006),
however higher efficiencies will be achieved when operating
with the catalyst. The following section only applies if the
catalytic performance pack (#0003406) has been purchased
and installed. The Dauntless FlexBurn
®
is designed and
certified to function with or without a catalyst. In the event
the combustor becomes non-functioning the combustor can
either be replaced or removed completely.
If a non-active catalyst is left installed in the unit, it will burn
sluggishly and produce noticeable smoke at the outlet of
the venting system. The simplest situation in that case is to
remove the deactivated catalyst and operate the unit as non-
catalytic. The catalyst can then be replaced as time allows
without producing a smoky burn or low heat output.
Under normal operating conditions, the catalytic combustor
should remain active for five to seven 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.
