FIREBOX, PILOT, & BURNER
TUBES
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 31.
Check to insure a flame is burning from
each burner port. The pilot flame should be
large enough to engulf the
sensor/thermocouple as shown in Figure 2.
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 34.
Figure 2: Pilot Flame Pattern
Complete the cleaning procedure by
carefully placing the log set within the
firebox as described on page 28. 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.
