If replacement of the refractory package is required,
proceed to #10.
10. Remove 1/4-20 x 1/2” hex head screw from the
damper tab holding the damper link to the damper and
let the link drop down.
11. Remove the two (2) 1/4-20 x 1
¹⁄₂” hex head screws
and washers holding the damper housing to the stove
back and drop the damper housing out of the stove.
12. Carefully slide the refractory package out of the
unit.
13. Install the new refractory package making sure to
pilot a small hole for the secondary probe in the proper
location at the back of the refractory package.
14. Reinstall the damper housing and damper link.
Watch for Better Results
Operate the stove in a typical manner for two weeks,
inspecting the chimney and the chimney connector fre-
quently during this period. If creosote is not building up
as fast, it is likely the performance change was caused
by fly ash deposits on the catalytic element. However,
continue the inspections of the chimney system for a
few weeks to ensure that proper performance contin-
ues.
If you continue to find a significant creosote build-up
or if you continue to see excessive smoke from the
chimney, the catalytic element will need to be replaced.
Contact your nearest Vermont Castings Authorized
Dealer for information about a replacement element.
NOTE: Use only the replacement catalyst #160-2521
supplied by CFM Corporation.
The refractory and the catalytic element are
extremely fragile and must be handled carefully.
The Chimney System
A Clean Chimney System is Safer
and Works Better
Although the catalytic combustion system in your Win-
terWarm Small Insert can reduce creosote formation
dramatically, it is not a substitute for regular inspection
and cleaning of the chimney and chimney connector.
Learn To Recognize —
And Avoid — Creosote
Your WinterWarm Small Insert has been designed to
minimize creosote build-up. Regular chimney inspection
and maintenance, however, must still be performed.
For safety, good stove performance, and to protect your
chimney and chimney connector, inspect your chimney
and chimney connector on a regular schedule. Clean
the system if necessary. Failure to keep the chimney
and connector system clean can result in a serious
chimney fire.
When wood is burned slowly, it produces tar, organic
vapors and moisture which combine to form creosote.
The creosote vapors condense in the relatively cool
chimney flue of a slow-burning fire. As a result, creo-
sote residue accumulates on the flue lining. When
ignited, this creosote makes an extremely hot fire within
the flue system that can damage the chimney and
overheat adjacent combustible material. If a significant
layer of creosote has accumulated —1/8” (3mm) or
more — it should be removed to reduce the risk of a
chimney fire.
If you do experience a chimney fire, act promptly to:
• Close the damper and thermostat lever.
• Get everyone out of the house.
• Call the Fire Department from a nearby house.
You should inspect the system every two weeks during
the heating season as part of a regular maintenance
schedule. To inspect the chimney, let the WinterWarm
Small Insert cool completely. Then, using a strong light,
sight up through the flue collar into the chimney flue. If it
is not possible to inspect the flue system in this fash-
ion, the firechamber must be removed to provide better
viewing access.
If it is necessary to remove the firechamber to inspect
or clean the chimney, this is how to do it:
• Let the WinterWarm Small Insert cool.
• Disconnect the fan power cord.
• You may wish to lighten the firebox by removing
the load door, andirons, grate and ash door.
• Retract the two levelling screws until they bear no
weight.
