Exterior cast iron parts are porcelainized with an
enamel finish. Use a damp sponge to wipe
clean. Dry the cast iron thoroughly to prevent
rusting.
Enamel castings can be cleaned with a standard
glass cleaner. With time and use, a very fine,
subtle network of crazed lines may appear
seemingly beneath the surface of the enamel.
Crazing is a natural predictable process and
does not represent a flaw.
TROUBLESHOOTING
Most are correctable and generally require only
a minor adjustment of the stove, installation, or
operating technique. In cases where weather
conditions dramatically affect stove
performance, the problems are typically
temporary and solve themselves once the
weather changes.
One common cause of poor performance is an
oversized chimney flue. Oversized chimney
flues result in decreased pressure, which
prevents the smoke from rising out the chimney.
Oversized flues are also more difficult to heat
effectively, especially when burning a high
efficiency stove. Cool flue temperatures inhibit
the establishment of a strong draft (and
encourage the accumulation of creosote). The
lack of a strong draft will cause the fire to die
down and may even force the smoke to pour
into the room.
If your chimney is the proper size and a strong
draft is not easily established, there is the
possibility of the chimney being too cold.
Again, hot chimneys promote a stronger draft.
Other draft guidelines are as follows:
AN "AIRTIGHT" HOUSE: If your home is
super-insulated or especially well sealed, the
(infiltration) air supply to the interior of the
house may be inadequate. This phenomenon of
air starvation within the building can be
exacerbated if exhaust fans, such as clothes
dryers, bathroom fans or cook-stove exhaust
fans, are in operation within the home. The
need for additional air may be accommodated
by opening a window to provide the adequate
air.
TALL TREES OR BUILDINGS: These
obstructions, when located in proximity to the
top of the chimney can cause chronic or
occasional downdrafts. When selecting a site
for a new chimney, take care to consider the
placement of other objects in the vicinity of the
proposed chimney location.
WIND VELOCITY: Generally, the stronger
and steadier a wind, the stronger (better) the
draft. However, "gusty" wind conditions may
cause erratic downdrafts.
BAROMETRIC PRESSURE: Chimney
drafts are typically sluggish on balmy, wet or
muggy days. This is a weather-related
phenomenon, which generally is self-correcting
as the weather changes.
BRISKNESS OF FIRE: The hotter the fire in
your stove, the hotter your chimney and,
therefore, the stronger the draft.
BREAKS IN THE VENTING SYSTEM: An
unsealed clean-out door at the bottom of the
chimney, leaky stovepipe joints, a poor
stovepipe-to-thimble connection, or a leaky
chimney may cause inadequate draft.
SEASONAL FACTORS: Early fall and late
spring are generally difficult seasons in which to
establish proper drafts. The colder the outside
air (relative to room temperatures), the stronger
the draft.
