1. Existing Masonry Chimneys
If you plan on using a pre-existing masonry chimney,
have it thoroughly inspected and cleaned. Any faults
which make the chimney unsafe and unusable must
be repaired prior to use. These can include improper
height, structural defects, blockages, inadequate
clearance to combustibles, unsealed openings into
other rooms of the house, signs of creosote or smoke
leakage, a loose or absent clean-out door, or absence
of a liner.
2. venting to a Masonry Chimney
When connecting to a masonry chimney, several
provisions are standard. First, whether the chimney
connector is vented to the chimney through a thimble
or a breech pipe, neither must pass beyond the inner
surface of the chimney liner, and both must be firmly
cemented in place with refractory cement. (A thimble is
a masonry pipe which is inserted through the chimney
wall, and is frequently the preferred method; a breech
pipe is a piece of steel pipe used the same way.) In
Canada, a breech pipe has ridges or protrusions to
lock it firmly into the refractory cement. In either case,
the chimney connector vents to the chimney through
the thimble or breech pipe.
Using a thimble, the connector slides completely
inside the masonry to the inner edge of the flue liner,
and may be easily removed for chimney and connector
inspection. A breech pipe must extend at least 2" (50
mm) into the room, so the connector can be attached
with sheet metal screws.
3. Venting to a masonry fireplace Chimney
In some situations, a code compliant chimney originally
used for a masonry fireplace may be used. In addition
to the requirements found in the previous paragraphs,
it is important to be aware that all clearances must be
met, including those from the chimney connector to
combustibles. Do not forget to include floor protection
in your plans. (See Clearances and Floor Protection
in this section.) Since many fireplaces have exposed
wooden mantels and trim, pay special attention to the
clearances necessary to these materials.
If your fireplace chimney is behind a combustible wall,
you must use an approved wall pass-through system
to gain access to the masonry chimney. The chimney
connector must enter the chimney at a place where it is
lined, and the fireplace must be made inoperable. For
example, you might remove the damper, replacing it
with a secure, airtight, noncombustible seal (removable
for inspection); this also satisfies the requirement that
no room air must be allowed to enter the chimney.
4. installing to a prefabricated Chimney
When venting using a prefabricated chimney, be sure
to contact local building code authorities, and to follow
the manufacturer’s instructions exactly. Use only the
manufacturer’s parts; do not use makeshift installation
techniques. All prefabricated chimneys must be
tested to either the U.S. or Canadian high-temperature
standards, UL 103 or ULC S629.
5. Other Considerations
Do not burn any fuel other than dry cordwood. Never
use highly volatile substances in your stove, such as
gasoline, which could cause an explosion.
When solid fuels are burned completely, they produce
water and carbon dioxide. However, in long slow
burns, a substantial amount of carbon monoxide may
be produced. If allowed to build up, carbon monoxide
(which is odorless) can prove fatally poisonous. Proper
ventilation and draft will prevent this from happening.
If you smell smoke, thoroughly ventilate your dwelling,
and contact your dealer for service.
Other causes of poor ventilation or draft are icing,
exhaust fans, a blocked outside air inlet, and room
air starvation. If your stove is sluggish and you get
occasional odor, check these possibilities and increase
the air flow in your home.
