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.

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 rmly 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 rmly 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 ue liner, and may be eas-

ily 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.

In some situations, a code compliant chimney originally

used for a masonry replace 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 oor protection in your plans.

(See Clearances and Floor Protection in this section.) Since

many replaces have exposed wooden mantels and trim, pay

special attention to the clearances necessary to these materials.

If your replace 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 replace

must be made inoperable. For example, you might remove the

damper, replacing it with a secure, airtight, noncombustible

seal (removable for inspection); this also satises the require-

ment that no room air must be allowed to enter the chimney.

When venting your TLC 2000 using a prefabricated chim-

ney, 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,

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 re screen, and be sure the bypass damper is open.

Do not burn any fuel other than those specied. Other

solid fuels, such as charcoal, can cause increased carbon

monoxide production or overring. 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 dwell-

ing. 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 ow in your home.
