Chapter 15 Service Procedures Compression fitting 15-12 Service Procedures Flair fitting a minor leak, put a magnet patch on it and call you supervisor for instructions. 6. Oil lines: oil lines, especially those in contact with concrete, can develop holes and leak. Do NOT cut out the leaking section and replace it with a new piece of copper. When a leak develops, replace the line from the tank to the burner; if the line is buried in or contacts concrete, install coated copper tubing or install the line in secondary containment. If you encounter a more serious leak, try to stop the flow of oil, shut off any sump pumps in the area and close off floor drains and any access to groundwater. Contact your office immediately and spread absorbent while you wait for help to arrive. #8 Odors, smoke, or soot Several different problems can cause these troubles, among them are: 1. Delayed ignition 2. Combustion problems 3. Dirty or defective chimney or flue 4. Insufficient air in boiler room 5. Air leaks in the boiler 6. Defective heat exchanger 7. House fan sucking air down the chimney #9 Noise These calls are often frustrating because the noise can be intermittent. When you arrive, the noise may have stopped and you will have to run the burner through several disassemble and inspect the flare. If the flare looks to be in good condition reconnect it, tighten it, clean it with an absorbent rag and run the burner. After several minutes inspect the fitting closely, if there’s any evidence of a leak cut out the flare, reflare the copper, reconnect it and keep checking until you’re sure the leak has been stopped. 2. Malleable fittings: If you find a leak at a malleable fitting, inspect it closely before taking it apart. If the leak appears to be coming from the area where the fitting is threaded, disassemble it, clean it, apply pipe joint compound and reconnect it. If the leak appears to be coming from a crack or sand hole, replace the fitting. 3. Fuel unit: If a leak appears to be coming from a fuel unit, check that all of the fittings, plugs and bolts that hold the cover are tight. If the leak continues, check the gasket; if it is leaking, replace it. If the pump is still leaking, replace it. 4. Oilburner: Most burners have a “weep hole” in the bottom that allows oil to drain from the housing. If you find such a leak check: • The pump seal. • The nozzle adaptor. • For an after-drip from the nozzle. 5. Tanks: Minor leaks at tanks often appear as drips or wet spots. If the tank has Staining indicates a leak in oil line coming through concrete floor
