MAINTENANCE

SMALL AREA PAINT TOUCH-UP

The stove body is painted with a quality high-temperature stove paint. Use only model TSPK-B Stove Paint, Catalog

# 70K99. Do not touch-up your stove with any other paint.

Using one small piece of 320 grit sand paper and lightly sand the blemish so that the edges are “feathered” or smooth to the touch between the painted and bare sur- faces. Do not let the sand paper gum up with paint, as this will cause scratches on the metal surface. If there are any scratches, use 600 grit sandpaper instead. Mask off surfaces you do not want painted. Paint lightly over the bare surface first as this will act as an undercoat. Then paint over a larger area in smooth even strokes to blend.

See Break-In Period on page 13 for information on curing the paint.

ASH REMOVAL AND DISPOSAL

CAUTION: MAKE SURE THAT THE FIRE IS OUT AND THE STOVE IS COLD BEFORE REMOVING ASHES!

Ashes can hold live embers for several days, and must be disposed of with care.

NEVER place ashes in a cardboard box or any other combustible receptacle.

Proper Disposal of Ashes:

Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal.

If the ashes are disposed of by burial in soil or other wise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.

DOOR, AND GLASS GASKETS

A 3/4" spun fiberglass rope gasket provides the seal around the fuel door and a 1/8” x 1” flat woven gasket glass provides the seal around the glass. Should these gaskets become frayed or damaged they should be re- placed 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 door gasket. The glass gasket has a self-adhesive backing (see Replace- ment Parts, pages 20-21).

WARNING: THE GASKETS MUST BE KEPT IN GOOD CONDITION. DO NOT LEAVE THE STOVE BURNING WITH THE FUEL DOOR 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 OVER- FIRING IT. OVERFIRING IS A CONDITION WHERE EXCESSIVE TEMPERATURES ARE REACHED, BE- YOND THE DESIGN CAPABILITIES OF THE STOVE (SUCH DAMAGE IS NOT COVERED BY THE MANU- FACTURERS WARRANTY).

FIREBRICK

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

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 DAMAGED, THEY MUST BE REPLACED BEFORE HEATER CAN BE SAFELY OPERATED. USE ONLY COMPONENTS PRO- VIDED 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 (pro- tective gloves are recommended).

2.Clean the 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.
