Gas Fired Boiler
11. Carefully remove the burner from the boiler and clean with pressurized water.
NOTE:
Do not attempt to wash the
burner while installed in the boiler. When cleaning the burner, use a mild detergent such as Simple Green to help
loosen built-up debris trapped in the burner mesh.
12. Now that the burner is removed, the burner hole is open which provides access to the combustion chamber.
13. Use a pressurized water hose with control nozzle. Begin by spraying just a few seconds of water into the
combustion chamber and then close off the nozzle.
14. Walk around to the rear of the boiler and ensure the wash water is draining into the temporary drain hose off the
condensate drain. Adjust the temporary drain hose if needed to help drain the wash water from the boiler.
15. After inspecting the temporary drain hose, continue washing the internal combustion chamber with pressurized
water for several minutes. Spray as much of the internal surface area as possible.
BE VERY CAREFUL
when
cleaning to avoid spraying any of the electrical or control components.
16. Some SONIC boiler models feature two small washout ports between the upper combustion chamber and lower
economizer. The plugs in these ports can be removed for additional access to the fireside surfaces. If necessary,
continue washing the fireside surfaces through these two washout ports.
17. After several minutes of washing, turn off the hose and allow all the wash water to drain from the boiler.
18. Reinstall the plugs into the two washout ports (if applicable).
19. Reconnect the condensate tubing to the condensate neutralization tank.
20. Reinstall the gasket over the boiler’s threaded studs, and
CAREFULLY
insert the burner into the burner hole.
Support the burner so it remains horizontal while inserting.
21. Once the burner is installed, reinstall the gasket over the burner’s flange.
22. Reinstall the burner transition piece (and lower gasket) and bolt to the burner flange.
23. Once secured to the burner flange, bolt the burner transition piece to the blower transition piece. Ensure the
gasket between the burner transition piece and blower transition piece is in place.
24. Reinstall the ignition electrode assembly (if previously removed).
25. Reinstall the flame/ionization rod assembly (if previously removed).
26. Reinstall the wires/cables to the ignition electrode and flame/ionization rod.
27. Double check the tightness of all bolted joints.
5.3 After Repairs or Maintenance
Following any major repairs or preventative maintenance, follow the steps below before returning the boiler to
service.
1. Follow “Pre-Start Check List” (Refer to
Section 3.8
) and all “Safety Checks” (Refer to
Section 3.9
).
2. Check the gas pressure (Refer to
Section 3.11.2
) and ensure proper operation of the boiler.
3. Perform combustion check (Refer to
Section 3.11.2
) and adjust air/gas mixture at high fire & low fire if
the O
2
% or CO
2
% are out of range.
NOTE: Installation and service must be performed by a qualified installer or service agency
that has been
trained on the Harsco Industrial, Patterson-Kelley boiler.
