Your appliance has been manufactured in the Blaze King tradition of high quality. To ensure years of trouble
free operation, have your furnace serviced regularly by your Blaze King dealer.
Periodically during heating season thoroughly clean the chimney and firebox so your system is ready for next
fall. Inspect all firebricks and replace any damaged bricks. A broken firebrick should be replaced to prevent
warping of the firebox.
OPERATE THE ALTERNATE ELECTRIC, GAS OR OIL FURNACE PERIODICALLY TO ENSURE THAT IT
WILL OPERATE SATISFACTORILY WHEN NEEDED.
INSPECT VENT PIPES, VENT PIPE JOINTS AND VENT PIPE SEALS REGULARLY TO ENSURE THAT
SMOKE AND FLUE GASES ARE NOT DRAWN INTO, OR CIRCULATED BY, THE AIR CIRCULATION
SYSTEM
ASHES
Ashes should be cleaned out when they reach a depth of 4" in the firebox (half way up the lower bricks).
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 otherwise locally dispersed,
they should be retained in the closed container until all cinders have thoroughly cooled.
CATALYTIC COMBUSTOR REPLACEMENT
If the combustor must be examined or replaced, follow this procedure;
1. Allow the furnace to burn out and cool down.
2. Open the door and the bypass door. Remove the flame shield underneath the combustor.
3. The combustor may now be seen. Push the combustor from underneath up into the area behind the
bypass door. The combustor can now be taken out thru the bypass opening.
4. The gasket material around the stainless band will probably disintegrate as the combustor is removed. If
the combustor is placed back in the furnace, the gasket material MUST be replaced. Obtain a piece of
gasket from your dealer. When installing the gasket ensure the ends are butted closely together.
5. Do not burn the furnace with the combustor removed, or without the gasket around the combustor.
6. To replace the combustor, first clean the combustor seat and the area around it. Also take this opportunity
to clean the area around the by-pass -- use a vacuum cleaner.
7. Lift the new combustor into position, with the stainless flanges up. The combustor should easily slide into
position. Don't be concerned if it appears a bit loose. The insulation around the outside of the stainless
band will expand during the first fire and will hold the combustor in.
8. Reinstall the flame shield
