MAINTENANCE

DOOR GASKET

A spun fiberglass gasket (3/4" [19 mm] in diameter) pro- vides the seal around the fuel door. Should this become frayed or damaged it should be replaced. Spun fiberglass "rope" gasketing can be purchased from your dealer. It must be the same diameter as the original. Use high temperature silicone sealer as an adhesive, which can also be purchased from your dealer.

WARNING! THE GASKETS MUST BE KEPT IN GOOD CONDITION. DO NOT LEAVE THE STOVE BURNING WITH THE DOOR OPEN OR AJAR (OTHER THAN START UP AND REFUELING AS DEFINED IN THIS MANUAL). THIS WILL CAUSE EXCESSIVE HEAT BUILD UP IN THE APPLIANCE AND COULD IGNITE SURROUNDING COMBUSTIBLES AS WELL AS DAM- AGE THE STOVE BY OVERFIRING IT. OVERFIRING IS A CONDITION WHERE EXCESSIVE TEMPERA- TURES ARE REACHED, BEYOND THE DESIGN CA- PABILITIES OF THE STOVE (SUCH DAMAGE IS NOT COVERED BY THE MANUFACTURER'S WARRANTY).

SERVICING GLASS

CAUTION: BE CAREFUL NOT TO ABUSE DOOR AS- SEMBLY BY STRIKING OR SLAMMING IT. IF THE DOOR ASSEMBLY OR GLASS IS BROKEN OR DAM- AGED, THEY MUST BE REPLACED BEFORE HEATER CAN BE SAFELY OPERATED. USE ONLY COMPONENTS PROVIDED BY THE MANUFAC- TURER AS REPLACEMENT PARTS.

Cleaning Glass: Ensure stove is cold prior to cleaning glass. A commercial glass cleaner designed for stoves is recommended. Do not use abrasive cleaners.

Replacing Glass:

1.Remove door from stove by lifting door up and off hinge pins: Place the door on a flat protected (towel) clean flat surface with the inside of the door facing up. Remove the glass clips (by removing screws holding clips), then carefully remove broken glass one piece at a time (protective gloves are recommended).

2.Clean area where the glass with gasket will be in- stalled.

3.Install new glass with gasket (use only factory 5-mm glass with glass channel gasket. Do not substitute). Carefully reinstall glass clips. Be very careful not to overtighten screws.

4.Reinstall door.

CLEANING BLOWERS

The blowers require inspection and cleaning annually to remove lint, dust, etc. If there are pets in the dwelling, the blowers should be cleaned at least twice a year To ac- cess, remove blower covers (remove the two ¼” [7 mm] hex head screws on each panel), then inspect propellers (replace if cracked, broken or melted) and vacuum out lint, dust, and debris.

CREOSOTE FORMATION AND NEED FOR REMOVAL What is Creosote - When wood is burned slowly, it pro- duces 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 accumulates 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 become too cool prior to exhausting. Note: Single wall pipe cools rapidly, there- fore installations using this type of flue are more suscep- tible to creosote deposits.

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 creo- sote accumulations in this manner. This must be re- moved from the chimney by scraping or brushing to re- duce 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.

Removal of Fireplace Insert for Inspection:

Pull Fireplace insert forward until the screws securing the flue connection can be accessed. Detach flue by remov- ing screws. Pull unit forward and out of fireplace. Inspect the chimney and chimney connector as follows:

Inspection Frequency - The chimney connector and chimney should be inspected at least twice monthly dur- ing 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.

To reinstall insert follow instructions on pages 9 and 10 (instructions # 8 through 12).
