REFRACTORY
The brick refractory on the interior of your
fireplace (sides, back and bottom) is manu-
factured with a high quality cement mixture
and reinforced with a wire mesh.
In a new fireplace or one with new refractory,
allow refractory to cure for 24 hours. When
building a fire, build a small one for the first
3 or 4 fires. The refractory is subjected to
expansion and contraction from the heating
and cooling of firebox during operation. It is
acceptable to operate the fireplace with cracks
of 1/64" wide.
If a crack should develop that is larger than
the hairline crack described, take the following
corrective measures:
1. Patch crack with a refractory patching
cement available at fireplace shops or
hardware stores. The refractory must still
be in one piece to patch.
2. Replace refractory panel (see fireplace
owner’s manual). DO NOT continue to
use your fireplace if your refractory has a
crack that exceeds 1/64".
Refractories are available through your ser-
vice dealer.
GRATE
If grate deteriorates or is distorted, replace
with DESA Heating, LLC grate designed
for your fireplace (see fireplace owner’s
manual).
GLASS DOORS
Clean glass with any commercial glass
cleaner or soap and water. Do not use any
abrasive material to clean glass. Do not clean
glass with cool water if glass is still hot from
use. Let doors dry completely before bulding
the next fire.

SMOKE
This fireplace has been designed to operate
without smoke spillage into the room when
installed and operated properly. In the event
a smoking problem does occur, check for one
of the following conditions:
1. Outside environmental conditions ad-
versely affecting draft.
2. Lack of ventilation due to a tightly insu-
lated house could prevent the fireplace
from drawing properly. If this happens,
open a window a small amount while
operating fireplace.
3. Other appliances competing for available
air in a tightly sealed home. These could
be heating appliances, kitchen exhaust
fans and bathroom exhaust fans.
4. Relationship of your house to hills, trees
and nearby taller buildings can affect wind
conditions which can have a direct effect
on your fireplace operation.
5, Chimney termination not installed to
proper height.
6. Blockage of flue or termination cap.
7. Flue and termination caked with creosote
buildup.
8. Grate too close to front of fireplace, not
positioned behind smoke shelf. Position
grate in designated area on brackets.
9. Damper not in fully opened position.
10. Outside air damper not in opened posi-
tion.
11. Operating fireplace with partially opened
doors.
12. Additional chimney pipe(s) may be neces-
sary under certain conditions. (Additional
chimney pipe available as accessory
item.)
IMPORTANT: For see-through and peninsula
models, air currents in the room can cause
some smoke spillage.
COLD AIR DRAFTS
In cold areas you must take special precau-
tions and follow COLD CLIMATE installation
instructions in your owner’s manual.
If cold air drafts are present when your fire-
place is not in operation check the following:
1. Air coming out of fireplace opening. Close
damper.
2. Air near sides of firebox interior. Close
outside combustion air damper.
3. Air coming in around sides of fireplace,
between fireplace and wall. Make sure
fireplace frame has been caulked to en-
closure of frame.
