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.
