WinterWarm Small Insert

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 1¹⁄₂” 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.

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.
