Sometimes it will be necessary to clean
accumulated ash from the glass surface; allowing
this ash to remain on the glass for long periods can
result in “etching” due to the acidity of the ash. The
creosote which accumulates on the glass should
burn off during hot res.
Never clean the glass while it is hot, and
use abrasive substances. Wash the surface with
cool water, and rinse thoroughly. You may wish to
use a non-abrasive cleaner specically designed
for use on stove glass. In any case, dry thoroughly
before relighting your stove.
Like all ne equipment, your TL300 requires
some routine maintenance and inspection. Follow
the guidelines in this section to assure safe,
efcient operation.
The stove’s exterior surface should be dusted
periodically with a soft cloth. For more thorough
cleaning, wait until the stove is cool before using
a damp cloth to clean any blemishes.
To avoid a rust build-up on the inner surfaces
of the controls, work the controls back and forth
several times during the summer or any prolonged
period when you are not using your stove.
The inside of the fire chamber should be
examined for damage to the refractory lining
material, grates, and casting. If any bricks have
been damaged, replace them with Harman
replacement parts. Be sure that all air holes in the
refractory are open. The Firedome combustion
package can be examined and/or cleaned with
the bricks removed.
If the stove’s glass is cracked or broken, you must
replace it before operating your stove. Remove
pieces carefully. Replace glass only with Harman
replacement glass; do not use substitutes.
To replace the glass panel, you will need to
remove the door. To do this, open the door, lift it
straight up and place it on a soft surface.
Carefully remove damaged glass, gasket
material, and hold down clips (set aside).
Referring to the diagram, note how the various
components of the door system t together. Lay the
load door face down on the soft surface, and install
the self adhesive 1/4"” gasket material around the
front face of the glass. Note: this glass has a special
IR coating on one side. This coating must be to the
of the stove. The coated side has a label
on it and/or will show resistance on a ohm meter.
Set the glass panel and gasket gently onto the
door. Install the hold down clips and tighten with
bolts as shown. Reinstall door on stove.
