The firebox should receive periodic cleaning
to prevent the accumulation of dust, lint, and
other debris. To clean the firebox, set the
thermostat to the “OFF” position, and turn
off the gas at the gas control valve. When
the unit is cool, unfasten the front door and
carefully remove the decorative ceramic
fiber log set, taking care not to damage the
logs or chip the enamel cast iron. Clean the
firebox burner tube and carefully vacuum
the entire surface of the log set. Thoroughly
vacuum the ports (holes) along the top of the
burner tubes.
With the decorative ceramic fiber logs out of
the firebox, fasten the door shut and
momentarily light the unit according to the
lighting instructions described on page 24.
Check to insure a flame is burning from
each burner port. The pilot flame should be
large enough to engulf the
sensor/thermocouple. Turn the unit off by
setting the thermostat to “OFF” and turning
off the gas control valve. Allow the unit to
cool. Check and clean any burner ports that
are not burning or not burning properly.
Clean burner ports using soft 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 26.

Complete the cleaning procedure by
carefully placing the log set within the
firebox as described on page 21. Close and
fasten the front door. Turn on the gas, light
the unit and check for proper operation.
Flame patterns should look like Figure 3.
Regularly check to insure the area around
the Tucson 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. Once a year the unit and venting
system should be inspected by qualified
service personnel to insure that they are
clean, free of obstruction, safe, and in good
working order. If service or maintenance is
required, it should be performed by qualified
service personnel.
