Refer to the “Catalytic Combustor Appendix” on
Page 37 for information on what kinds of damage or
deterioration to look for. Although small hairline cracks
will not affect performance, the combustor should be
essentially intact. If the combustor is broken in pieces
or has sections missing, it should be replaced. Call your
local Vermont Castings’ dealer for a replacement
combustor, item #30001152. Consult the warranty
section at the back of this manual for further information
on catalytic combustor replacement.

While the catalytic element is removed, check the
condition of the secondary air probe. Use an inspection
mirror to locate the probe within the combustion cham-
ber. (Fig. 17) The probe should extend 1 to 1
¹⁄₂
" (25 -
38mm) into the chamber and show no signs of
deterioration, (warping, short length). Refer to the next
illustration. A damaged secondary air probe could affect
catalytic performance. If the probe needs to be
replaced, call your local dealer.
If the combustor is in good condition and clean, re-
install it following this procedure:
1. Slide the element carefully back into the refractory
chamber, seating it securely. The element must be
fully to the rear of the support slot.
2. Install the access panel, making sure that it is flush
with the outer surface of the main refractory
package.
3. Check the slot in the rear bottom plate for debris,
and clean if necessary.

4. Reinstall the lower fireback by inserting the base of
the fireback in the slot. Tip the fireback up into
place.
5. Reinstall the throat pieces, center edges first, then
outer edges. Tap the throat pieces downward firmly
to seat the lower fireback.
6. Replace the grate.
7. Replace the front grate bar. With the horizontal bars
pointing down and away from you, angle the bar
inside the firebox to seat the right end. Then, bring
the left end forward and lower it into position.
Watch for Better Results
Finish up by cleaning the chimney and chimney con-
nector. Then, use your WinterWarm in a typical man-
ner for two weeks and observe its performance, taking
particular note of the smoke observation test described
on Page 11.
If a problem persists, contact your local dealer for
further advice about your particular situation.
The Chimney System
A Clean Chimney System is
Safer and Works Better
Although the catalytic combustion system in your
WinterWarm can reduce creosote formation dramati-
cally, it is not a substitute for regular inspection and
cleaning of the chimney and chimney connector.
Learn to Recognize —
and Avoid — Creosote
Your WinterWarm has been designed to reduce creo-
sote build-up significantly. However, regular chimney
inspection and maintenance must still be performed.
For safety, good stove performance, and to protect your
chimney and chimney connector, inspect your chimney
