Ways To Add Fuel - Vermont Castings 2115 Owner's Manual

While not required, operating your stove with the catalytic
combustor installed creates optimum conditions for
secondary combustion and will increase your efficiency up
to 15% on low burn, making sure you get the most heat out
of each load of wood.
The catalytic element is a ceramic "honeycomb" coated
with the catalytic material. The element sits at the bottom
of the secondary combustion chamber. Smoke, gases
and particulates that are not fully combusted during the
secondary combustion process pass through the catalyst,
creating a tertiary burn. This results in higher efficiency and
lower emissions.
The catalyst will initiate combustion of smoke and particulates
at 500° - 600°F (260° - 315°C), half the temperature normally
required for unaided secondary combustion. If you followed
the startup operation steps in the previous section the stove
will be sufficiently hot to allow the combustor to work. Once
the combustor starts working, heat generated by burning
the smoke will keep it working.
To determine whether the combustor is operating, refer to
the temperature probe which shows the operating range
of the catalytic combustor. This is located on the back of
the stove and is viewed from the top. NOTE: It will take
several minutes after closing the bypass damper for the
temperature probe to fully adjust to the new temperature. If
the probe indicator is below the operate catalyst range when
the bypass damper is closed, add fuel or open the bypass
damper to allow the fire to further build before engaging the
catalyst again.
If the probe indicator is above the operate catalyst range,
the catalytic combustor is running too hot and may be
damaged. In many cases, decreasing the primary air can
reduce the catalyst temperature and adding less wood with
each loading can also help if overheating is persistent. Do
not add wood to the stove if the probe reads above the
operate catalyst range.
Avoid using a full load of very dry wood in the firebox, such
as dry slab wood or wood with below 14% moisture content.
This may result in continuous very high temperatures in the
secondary combustion area and damage the combustor.
Never burn treated wood, garbage, solvents or trash. All of
these may poison the catalyst and prevent it from operating
properly. Never burn cardboard or loose paper except for
kindling purposes. Never burn coal; doing so can produce
soot or large flakes of char or fly ash that can coat the
combustor and cause smoke to spill into the room. Coal
smoke can also poison the catalyst so that it won't operate
properly.
11 Vermont Castings • Intrepid FlexBurn
C. Ways to Add Fuel
The Intrepid FlexBurn's griddle lifts for convenient top-loading
of logs, and is the easiest way to add fuel. (Figure 2.5)
However, the front doors open as well for adding an
occasional log to the fire. The Intrepid FlexBurn
is not approved for operation with the front doors open.
Figure 2.5 - Top loading is the best way to add fuel during regular
use. Front loading is useful for kindling a fire.
To open the front doors, insert the handle into the door latch
stub and turn it clockwise. (Figure 2.6)
To close them, always close the left door first. Turn the
handle in the right door to the left and up (to the open
position) and close it. Finally, push on the door as you turn
the handle counterclockwise. The doors will draw in slightly,
and the handle should offer some resistance as you turn it
to the closed position.
To reduce the risk of breaking the glass, avoid striking the
glass or slamming the doors.
When you are not using the door handle, store it in the
holder behind the right front leg of the stove.

Fire Risk
• Do not leave the fire unattended when the
door is unlatched
• Operate only with front doors and ash pan
door closed.
• Unstable firewood could fall out of the firebox
creating a fire hazard to your home.
