Maintenance
Like all fine equipment, your insert requires some routine
maintenance and inspection. Follow the guidelines in this
section to guarantee safe and efficient operation.
surface
The insert’s exterior surface should be dusted periodically
with a soft cloth. For more thorough cleaning, wait until
the insert is cool before using a damp cloth to clean any
blemishes.
the door
If the door needs to be cleaned, wait until the insert is
completely cool, then use a sponge, soap and water to gently
remove dirt and stains. Before relighting the insert, remove
all soap residue and wipe dry.
Controls
To avoid a rust buildup 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 insert.
the fire chamber
The inside of the fire chamber should be examined for
damage to the refractory lining material, or bricks. If any of
these parts have been damaged, replace them only with
Harman supplied replacement parts.
The ramp brick must be removed to allow vacuum access
for cleaning the front portion of the combustion package.
Always use caution when refueling or when vacuuming the
firebox and combustion package. Some users have damaged
their combustion package with vacuum cleaner tools, and
fire pokers.

glass - replacement
The viewing glass is a specially designed 5mm ceramic
material. If the insert’s glass is cracked or broken, you must
replace it before operating your insert. Remove pieces
carefully. Replace the glass only with Harman supplied
replacement glass, part # 3-40-06932; 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 face
down on a flat 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 fit together. Lay the load door face down on
the flat surface. 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
outside
of the insert. The coated side has a label on it.
Do not remove the label before installing the glass. Remove
label before burning the unit. If the label has been removed,
you can determine which side has the coating by using an
OHM meter. The side with the coating will show resistance.
Set the glass panel and gasket gently onto the door. Install
the hold down clips and tighten with bolts as shown. Reinstall
door on insert.
Handle glass with care.

•
Avoid striking, scratching, or slamming glass.
•
Do NOT Clean Glass When Hot.
•
Do NOT use abrasive cleaners.
•

CAUTION
!
glass - cleaning
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. Any creosote which accumulates on the glass
should burn off during your hot fires.
Never clean the glass while it is hot, and do
not
use abrasive
substances. Wash the surface with cool water, and rinse
thoroughly. You may wish to use a nonabrasive cleaner
specifically designed for use on stove glass. In any case,
dry thoroughly before relighting your insert.
when cleaning in the rear of the firebox, near the
entrance to the firedome. do not poke cleaning tools
into the throat of the firedome as this may cause
damage to the refractory material.
CAUTION
