Harman TL300 7

The Stove

Doors

Your stove has a large glass-paneled door for loading and 

fire viewing, a separate smaller door for removing ashes, and 

a top loading door.  

Front Door

Before opening, always check for wood, embers, or ash 

that may be ready to fall out of the door. 

To open the glass door, open bypass damper first, by pulling 

forward on the top load door handle, to the first position. Then 

lift up on the front door handle to disengage the latch, and pull 

out. To close the door, push door closed with handle in the 

open position, then push handle down to engage the latch.  

Ash Door

To open the ash door, open the bypass damper first. Lift up 

on the ash door handle and pull it open. Close the door by 

pushing in and pushing the handle all the way down. 

Top Load Door

To open the top load door, pull forward on the top load 

door handle. The first position tells you the bypass damper is 

open. Continue pivoting the handle toward you until it locks 

the top load door open.

All  doors  must  be  closed  while  the  stove  is  in  normal 

operation, and the gaskets routinely examined for wear and 

replaced when necessary.  Good door seals are important for 

maintaining control of the stove.  Never operate with the ash 

door open. Operating the stove with the ash door open, or with 

a door improperly sealed, could create a serious overfiring 

condition (discussed later in this section).

General Considerations

Draft

Before you install and/or operate your TL300 wood stove, 

please read the entire contents of this manual. Pay particular 

attention to the explanation of draft and its effect on stove 

performance, in the installation section. By following the 

installation and operating guidelines, you will ensure proper 

draft and gain maximum efficiency and enjoyment from 

your stove.

Fuel

Your TL300  burns wood very efficiently.  Here are some 

guidelines concerning log size and moisture content that will 

help you obtain the best performance.

Select  dry  seasoned  wood.  For  example,  it  should  be 

checked or cracked on the ends and not exposed to rain or 

extremely damp conditions. Hardwoods are favored because 

they are heavier and contain more heating capacity (BTU’s) 

per load than do softwoods.  Wood should be split and stored 

under cover for “seasoning” - a year is recommended.  Your 

stove is not an incinerator - do not burn garbage, painted or 

treated wood, plastics, or other debris.

Keep the area around the stove free from clutter.  Keep 

all combustibles, including fuel, beyond the code-required 

clearance distance (48" or 1215 mm in the U.S., 1525 mm 

or 60" in Canada).  Never store fuel in front of the stove 

where it could interfere with door operation, safe loading, 

and ash removal.

Do not burn garbage or flammable fluids such 

as gasoline, naptha, or engine oil.

Specifications

NEVER OPERATE WITH MORE THAN 

ONE DOOR OPEN AT A TIME.

The glass used in your TL300 is manufactured to exact 

standards to withstand the high heat of the fire, but like all 

glass, it must be treated with common sense and care.  Never 

abuse the  glass by slamming the door shut or striking the glass 

with a heavy object.  If the glass is broken or damaged, do not 

operate the stove until it has been replaced (See instructions 

in Maintenance section.)

Grates 

The Harman TL300 has a unique grate system that consists 

of one bottom grate, and two front andirons.  The bottom grate 

has slots which allow the ash to fall into the ash pan by passing 

a poker back and forth across the grate. The andirons keep 

the fuel from coming into direct contact with the glass, and 

keep hot coals and embers from spilling out while reloading. 

Never build a fire directly against the glass. Andiron exten-

sions (included with each stove) clip onto the fixed andirons 

and serve to protect the glass when top loading is used as 

the primary loading method. The grates and andirons must 

remain in place at all times. Do not tamper with or change 

the configuration of this grate system.

CAUTION: 

Always wear fire retardant gloves 

when operating the stove.
