DOOR / GLASS GASKET AND ASH DRAWER GAS- KET

A 3/4" (19 mm) spun fiberglass gasket provides the seal around the fuel door and a 1/8” (3.2 mm) x 1” (25.4 mm) flat woven gasket glass provides the seal around the glass. A ½” (13 mm) flat fiberglass gasket provides the seal around the ash drawer. Should these gaskets be- come frayed or damaged, they should be replaced with the same size and type as the original gasket. Contact your dealer for ordering. Use high temperature silicone sealer as an adhesive for the fuel door gasket. The glass and ash drawer gaskets have self-adhesive back- ing.

WARNING: THE GASKETS MUST BE KEPT IN GOOD

CONDITION. DO NOT LEAVE THE STOVE BURNING WITH THE DOOR OR ASH DRAWER OPEN OR AJAR. THIS WILL CAUSE EXCESSIVE HEAT BUILD UP IN THE UNIT AND COULD IGNITE SURROUNDING COMBUSTI- BLES AS WELL AS DAMAGE THE STOVE BY OVERFIR- ING IT. OVERFIRING IS A CONDITION WHERE EXCES- SIVE TEMPERATURES ARE REACHED, BEYOND THE DESIGN CAPABILITIES OF THE STOVE (SUCH DAMAGE IS NOT COVERED BY THE MANUFACTURER'S WAR- RANTY).

SERVICING GLASS

CAUTION: BE CAREFUL NOT TO ABUSE THE DOOR ASSEMBLY 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 COMPO- NENTS PROVIDED BY THE MANUFACTURER AS REPLACEMENT PARTS.

Cleaning Glass: Ensure stove is cold prior to cleaning glass. A commercial glass cleaner designed for stoves is recom- mended. 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.

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 ex- tremely 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 suscepti- ble 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.

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 Combus- tor, page 20 for instructions on removing catalytic com- bustor.

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 im- mediately. After a chimney fire, the complete chimney system should be checked by a qualified technician be- fore further use.

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