MAINTENANCE

CREOSOTE FORMATION AND NEED FOR RE- MOVAL

What is Creosote - When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accu- mulates on the flue lining. When ignited this creosote makes an extremely hot fire. Also, creosote deposits tend to form in long runs of venting where gases be- come too cool prior to exhausting.

To inhibit the build up of creosote, adjust the primary air control to a medium-high or high setting for a 10-minute period each day. Do not attempt to burn out heavy creosote accumulations in this manner. This must be removed from the chimney by scraping or brushing to reduce the risk of a chimney fire.

Burn Approved Fuel Only - This stove is approved for burning dry seasoned natural wood only. Using green or inadequately seasoned wood may increase creosote buildup.

Inspection Frequency - The chimney connector and chimney should be inspected at least twice monthly during the heating season to determine if a creosote buildup has occurred. If creosote has accumulated it should be removed to reduce the risk of a chimney fire.

Cleaning - Remove the catalytic combustor and open the bypass damper prior to having your chimney cleaned (should be done by a qualified chimney sweep). See Maintenance Section, Catalytic Combustor, page 19 for instructions on removing catalytic combustor.

IMPORTANT: Make sure the bypass damper is in the open position prior to chimney cleaning.

In the event of a chimney fire - Make sure the fuel door is securely closed. Adjust the primary air control to the lowest (most closed) setting. Call the fire department immediately. After a chimney fire, the complete chimney system should be checked by a qualified technician before further use.

Consult your dealer for suggestions on proper chimney care. Contact your local municipal or provincial fire authority for information on how to handle a chimney fire. Have a clearly understood plan for handling a chimney fire.

CATALYST REPLACEMENT

The normal expected life of a catalyst (catalytic com- bustor) is 10,000 to 12,000 hours if the appliance is op- erated correctly and proper fuels are used. If the cata- lyst has been deactivated, it should be replaced. Symp- toms of deactivation include – noticeably darker smoke exiting chimney and less heat output. If these symptoms remain after normal maintenance or a major cleaning (soak in heated vinegar/water solution, see page 19), the catalyst, p/n 14000 will require replacement (also, if the catalyst is broken and / or missing large pieces, it should be replaced). Note: The catalyst does not need to be glowing to be working. It will glow at times, but it can work very effectively at temperatures well below the 1000° F level (at which it will begin to glow).

Stove Operation if Catalyst Is Deactivated – It is safe to operate the appliance temporarily with a deactivated catalyst (although it will be out of compliance with EPA certification requirements). To operate, follow normal lighting and refueling procedures as outlined in this manual with one the following exceptions.

•During start-up, disregard catalytic temperature probe reading to determine when to close bypass damper control. Instead allow 20-25 minutes, then close the bypass damper control.

•During refueling, disregard catalytic temperature probe reading to determine when to close bypass damper control. Instead allow 3-5 minutes after re- fueling, then close the bypass damper control.

CLEANING BLOWER INTAKE

If an optional blower kit (catalog #14M36) is installed, the blower air intake requires cleaning at least once a year to remove lint, dust, etc. If there are pets in the dwelling, the intake should be cleaned at least twice a year.

STOVE SEAMS

The stove body seams should be inspected at least once a year. If any seams are found to be loose or damaged, the seam should be cleaned with a wire brush then resealed with furnace cement.

FIREBRICK

The firebrick should be inspected periodically and re- placed if damaged (crumbling or excessively cracked).
