10. Carefully remove the triangular burner from the boiler and clean with pressurized water
(approximately 40 psig).
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.
11.
Now that the burner is removed, the burner hole is open which provides access to the combustion
chamber.
12.
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.
13.
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.
14. 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. Water may cause a short circuit and damage circuitry.
15.
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.
16.
After several minutes of washing, turn off the hose and allow all the wash water to drain from the
boiler.
17.
Reinstall the plugs into the two washout ports (if applicable).
18.
Reconnect the condensate tubing to the condensate neutralization tank.
19.
Reinstall a new 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.
20.
Once the burner is installed, reinstall a new gasket over the burner's flange.
21.
Reinstall the burner transition piece (and lower gasket) and bolt to the burner flange.
22.
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.
23.
Reinstall the ignition electrode assembly (if previously removed).
24.
Reinstall the flame/ionization rod assembly (if previously removed).
25.
Reinstall the wires/cables to the ignition electrode and flame/ionization rod.
26.
Double check the tightness of all bolted joints.
