Inspection Procedures

Burners

Clean main burners and air louvers of dust, lint and debris. Keep boiler area clear and free from com- bustibles and flammable liquids. Do not obstruct the flow of combustion and ventilation air. Make visual check of burner and pilot flame. Yellow flame indicates clogging of air openings. Lifting or blowing flame indi- cates high gas pressure. Low flame indicates low gas pressure.

NOTE: Modulating burner flame varies in height from approximately 1/4" at low fire to approximately 4" in high fire.

Inspection Schedule

To be performed the first and third month after initial start up and then on an annual basis. If problems are found, refer to Troubleshooting Guide for additional directions.

1.Remove top of boiler and inspect heat exchanger for soot and examine venting system.

2.Remove rear header and inspect for scale deposits.

*3. Inspect pilot and main burner flame and firing rate.

*4. Inspect and operate all controls and gas valve.

*5. Visually inspect system for water leaks.

*6. Inspect oil pump motor and bearing assembly, if oil cups are provided.

7. Check flow switch paddle.

8. Clean room air intake openings to ensure ade- quate flow of combustion and ventilation air.

9. Keep boiler area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

*Should be checked monthly. (Takes approximately 15 minutes).

Low Water Cut-Off (When Installed)

The low water cut-off automatically shuts down burner whenever water level drops below probe. 90 second time delay prevents premature lockout due to tempo- rary conditions such as power failure or air pockets. Flush float type devices at beginning of each heating season.

Procedure for Cleaning Flue Gas Passageways

Soot will clog areas behind fins and eventually cause tube failure. Any sign of soot at base of burners or around outer jacket indicates a need for cleaning.

1.Lift off drafthood and flue collector by removing bolts and screws.

2.Remove "V" baffles from heat exchanger.

3.Remove burner tray, see Burner Tray Removal.

4.Take garden hose and wash heat exchanger, mak- ing sure soot is removed from between fins. (Avoid excessive water against refractory).

5.Reassemble; when boiler is fired, some steam will form from wet refractory. This is normal.

NOTE: In extreme cases it may be necessary to remove the heat exchanger completely for cleaning. The simplest method is steam cleaning at a local car wash. DO NOT WIRE BRUSH!

CAUTION: Soot is combustible, so exercise extreme care.
