WARNING: Do not clean the unit when hot.
The unit should receive regular cleaning on, under, and
around the stove to prevent the buildup of dust and lint. The
exterior surfaces of the unit can be cleaned using soap,
water, and a soft cloth.
Do not
use abrasive or chemical
cleaners and take care not to scratch the glass or enamel
finish (if so equipped) when cleaning the unit. The use of
chemical wax based cleaners or polishes are not
recommended due to the potential for discoloration of the
stones, castings or enamel when the residues of the cleaners
or polishes are exposed to heat. Excessive buildup of dust,
spider webs, or room air contamination may cause odors
when the stove is hot.

SSEMBLY
The firebox requires periodic cleaning to prevent the
accumulation of dust, lint, and other debris. To clean the
firebox, set the ON/OFF/REMOTE switch to the “OFF”
position, and turn off the gas at the gas control valve. When
the unit is cool, open the front door. Carefully remove the
decorative stone set, taking care not to damage the stones or
chip the enamel cast iron. Clean the firebox and burner,
and carefully vacuum the entire surface of the stone set.
Thoroughly vacuum the ports (holes) along the top of the
burner, and the pilot assembly.
With the decorative stones out of the firebox. Briefly light
the unit. Check to insure a proper flame is burning from
each burner port. The pilot flame should be large enough to
engulf the thermopile and thermocouple as shown in
Figure
11.
NOTE: Do not operate the unit for more than 1-2
minutes without the stone set in place. Turn the unit off
by setting the thermostat to “OFF”, and turning the gas
control valve off. Allow the unit to cool.
Check and clean any burner ports that are not burning, or
not burning properly. Clean burner ports using a soft brush
or vacuum cleaner. If the pilot flame height needs
adjustment, it should be adjusted by qualified service
personnel as described on
page 18
.
Complete the cleaning procedure by carefully placing the
stone set within the firebox. Re-install the glass assembly
and front cast. Turn on the gas, light the unit and check for
proper operation. Flame patterns should look similar to the
flames in
Figure 12
. Regularly check to insure the area
around the Modena is kept free from combustible materials,
gasoline, and other flammable vapors and liquids. Check
that the flow of combustion and ventilation air is not
obstructed.
