7.12 Reassembly of the Burner Modules

Follow the instructions to reassemble the burner modules:

Reassembling the Burner Modules

1. After the cleaning of the boiler combustion chamber and/or the burners, reposition the

burners in their proper positions.

2. Position the new gaskets onto each burner module and ensure proper positioning. Make

sure all surfaces are smooth and free of debris.

WARNING!

The burner gaskets MUST be replaced at every cleaning.

3. Proceed with reassembly, performing whichever disassembly operation was chosen (all or

individual method) in reverse order.
a) Lower burner assembly

b) Reinstall gas collector tubes to the gas manifold tube.

c) Reinstall nuts “A,” “C” and “B” screws to secure burner assembly to boiler body.

NOTE

Tighten the burner bolts with a torque of

13 Nm.

d) Reassemble rubber hoses to the air intake manifold, place manifold onto the blowers,

then reattach tension spring clip to left and right ends of manifold.

e) Proceed to section 7.13 for final procedures before returning boiler to service.

7.13 Final Procedures after Maintenance

Before returning the boiler to service, the following procedures must be performed:

Final Procedures after Maintenance

1. Before lighting the boiler ensure the condensate line has been filled with water (Figure 7-1).
2. Ensure the seal between the gas supply pipe and the gas collection tube flange are tight. To

do this, open the external gas valve and bubble check for leaks using a soap solution.

3. When a single burner is ignited, check immediately to ensure that the gas valve and the

relevant premixing chamber are operating correctly.

4. Perform the combustion gas analysis and check all parameters (see section 3.33).
5. Make sure that all the pressure test nipples, previously opened, have been closed.
