CARE AND MAINTENANCE
To obtain the highest levels of performance of your furnace,
certain maintenance procedures are required periodically to
avoid soot, creosote, and ash buildup.
On a daily basis, you need to:
• Check for ash and creosote buildup until experience shows
how often cleaning is necessary.
• Ensure that the door gasket is sealing properly. Ensure that
door and ash drawer are closed and sealing properly.
• Check water level.
• Check for sparks or coals that may have fallen from the
furnace and make sure they are safely disposed of.
On a weekly basis, you need to:
• Remove ashes.
• Check for ash and creosote build-up in the bypass trough, top heat
exchange chamber, and chimney. Fly ash should be removed to
allow free airow through the furnace. An ash-choked furnace
ue will reduce the burn rate and create poor heat transfer.
• Removal of creosote may be necessary for mild weather.
Burning your furnace with a larger differential at higher
temperatures means less creosote buildup.
On a seasonal basis when the furnace is not in
use, you will have to:
• Remove all ashes and excess creosote.
• Remove the blower box from the rear of the furnace and
clean out any debris and ash
• Inspect the rebox for leaks and any other possible problems.
• Clean out bypass trough and chimney.
• Cover chimney and crack open the ash pan door enough to allow
air movement and reduction of condensation within the rebox.
• Have your water treatment tested and adjusted to manufacturer’s
specications. See page 5 for exact specications.
• Change any water lter cartridges and inspect all of your
system for leaks.
• Tighten your rebox door by adjusting the hinges on each
side of the door.
• Cleaning of the heat exchanger, ue pipe, chimney, and
draft inducer if used, is especially important at the end
of the heating season to minimize corrosion during the
summer months caused by accumulated ash.
Creosote and Fly Ash Formation and Need for Removal.
ATTENTION: Have a clearly understood plan to handle
a runaway re or chimney re. When coal 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
ue of a slow-burning re. As a result, creosote residue
accumulates on the ue lining. When ignited, this creosote
makes an extremely hot re. The chimney and chimney
connector 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 re.
• Disposal of Ashes - Ashes should be placed in a metal
container with a tight-tting lid. Other waste shall not be
placed in this container. The closed container should be
placed on a non-combustible oor or on the ground well
away from all combustible materials before nal 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.
CAUTION: Make certain that all electrical power to the furnace
and components is shut off. It can be washed using water
and a mild non-abrasive cleaner suitable for painted surfaces.
ATTENTION: Avoid direct water pressure to electrical
components and connections.
