BURNER HEAD REMOVAL
13. Remove the four ½ turn screws holding the upper front boiler jacket access panel and set the panel aside.
14. Remove the two screws holding the jacket top cover on, pick up, and slide forward on the panel to remove it. Set it
aside.
15. Remove the electrical wire quick connect on the top of the flame rod.
16. Remove the two screws holding the flame rod and pull the flame rod out of the burner flange. Be especially careful not
to destroy the high temperature flame rod gasket.
17. Thoroughly clean the flame rod with scotch brite or any such cleaning pad.
18. Reinsert the flame rod and tighten the two screws.
19. Using two wrenches disconnect the flexible gas line below the service valve at the flare fitting.
20. Disconnect the two electrical wiring connectors at the fan housing. The connector holding clips are on the sides of the
three pin connector and on the back of the four pin connector. They are both press to release type.
21. Disconnect the electrical wiring connector connecting the wires to the top of the burner.
22. Remove the six nuts holding the burner flange to the top of the heat exchanger.
23. Lift the burner and flange straight up about 2 inches and rotate the fan toward you. Tilt the fan down while picking up
on the burner. Lift it high enough to remove it from the boiler.
24. Place the burner on a flat surface with the nozzle pointing upward. Be especially careful not to damage the igniter.
Clean Turbulators
25. Pull each turbulator up about 3-4 inches; turn them back and forth to loosen any accumulated debris.
26. If it looks like the boiler needs to be flushed, remove the condensate trap and place a bucket or tray below the
condensate outlet and spray the furnace area with a citric acid based cleaner and a soft brush. Then rinse thoroughly
with clean water and push back down into the tube.
27. If the condensate trap was removed, then reinstall the trap.
28. When using the citrus cleaner, wear eye protection and rubber gloves. Use of cleaners containing chlorine, sodium or
other acids will void the warranty.
29. Clean burner sight glass and double check insulation around igniter.
Reinstall Burner
30. Reverse these instructions to reinstall the burner.
Check Wiring
31. Using a thin blade screwdriver verify all the screws attaching the electrical wiring to the connectors on the burner
control, to the Condensing Manager, and inside the electrical junction box are all tight.
Check Condensate Parts
32. Remove and clean the condensate trap. Verify that the sealing ball is present inside of the trap.
33. Check the condensate neutralizer for adequate amount of neutralizing chips, replace as needed.
Start and Check Operation
34. Start up boiler and perform a combustion analysis. (See Start Up Procedure)
Confirm Low Water Cut Off Functionality
35. Every year: Press “TEST” button on LWCO while burner is firing- “LOW WATER” LED will turn on, confirm the burner
shuts down.
36. Every 5 years: Remove LWCO and clean sensing probe- reinstall LWCO and confirm burner lights.
