8.14 Final Procedures After Maintenance

Before returning the boiler to service, the following procedures must be performed:
1. Before lighting the boiler ensure the condensate line has been filled with water (Figure 8-1).
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 4.33).
5. Make sure that all the pressure test nipples, previously opened, have been closed.
