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.

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 sheetmetal screws.
venting to a masonry Fireplace Chimney
In some situations, a code compliant chimney
originally used for a masonry fireplace may be used to
install your TLC 2000. 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 — 18"
(360 mm) to sides and 18" (450 mm) to ceiling. 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.
Chimney System
Installing to a Prefabricated Chimney
When venting your TLC 2000 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-629.

The Harman TLC 2000 was tested with the fuel door
open and closed.
If you operate with the door open, be sure to install the
optional fire screen, and be sure the bypass damper is
open.
Do not burn any fuel other than those specified. Other
solid fuels, such as charcoal, can cause increased carbon
monoxide production or overfiring. 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, turn
up the air control lever setting, and thoroughly ventilate
your dwelling. During future burns, be careful not to
overload the stove with fuel, so you will not be tempted to
constantly operate at a low air control setting.
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.
