Harman TL300

Do not burn any fuel other than wood, such as charcoal, 

which 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.

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 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.

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 

TL300. In addition to the requirements found in the previ-

ous 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 sec-

tion.)  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, noncombus-

tible seal (removable for inspection); this also satisfies the 

requirement that no room air must be allowed to enter the 

chimney.

Installing to a Prefabricated Chimney

When venting your TL300 using a prefabricated chimney, 

be sure to contact local building code authorities, and to fol-

low  the  manufacturer’s  instructions 

exactly

.  Use  only  the 

manufacturer’s parts; do not use makeshift installation tech-

niques.  All prefabricated chimneys must be tested to either 

the U.S. or Canadian high-temperature standards, UL 103 or 

ULC S629.

The Harman TL300 was tested with the fuel  

door  open  and  closed.  Keep  door  closed  for 

normal  operating  conditions.  If  you  operate 

with the door open, open the by-pass damper 

and put a screen over the door opening.
