Before getting started, remember...........
All BAXI LUNA boilers are tested during manufacture for correct operation and are
shipped to you factory tested for correct operation.
Most of the faults experienced on start up are field issues associated with items
external to the boiler. These are mostly simple problems, such as:
•
Venting installed incorrectly
•
Air in the system (system must be fully purged)
•
Air in the gas line
•
Undersized gas line
•
System not flushed (cold flush then hot flush)
•
Incorrect connection of external equipment
•
Leaks in the Heating system and pipe-work
When commissioning the boiler, only a few items need to be checked:
•
Inlet gas pressure (static and working inlet pressure of boiler running at
maximum output)
•
Maximum and minimum burner pressures
•
Power supply for polarity and ground
When troubleshooting BAXI LUNA boilers avoid changing parts prematurely,
assuming that the boiler component is defective. In our experience, items such as the
control PCB are changed incorrectly, when it is another component supplying false
information to it. Likewise, the pump is changed because it has stopped operating.
This is normally due to contamination from a dirty hydronic system. The pump can be
removed and cleaned; after which the heating system must be flushed and cleaned.
Get all the information before going to the job site...............
Get as much information from your customer before you go to the boiler. Model of
boiler, type of venting, type of system and layout connected to the boiler, how long has
the system been installed and is this an isolated breakdown or are they repeatedly
resetting the boiler.
Don't be afraid to ask the obvious questions! Do they know how to reset the boiler?
Just unplugging the lead and replacing it or turning the boiler off and on again will
not reset the logic board. They have to turn the switch to the "R" to restart the boiler.
Is there any water in the system? Where is the needle on the pressure gauge? This
may save an unnecessary trip to the job site.

Questions and answers
Hello, My ****years old Baxi Luna 310Fi is working flawlessly. But recently the unit started to discharge water through the discharge valve during the heating cycle only. I have a 5-gallon bucket which will get full of water within about three days. Please let me know if there is any solution to this problem. Thank you.
A possible cause of water discharge through the discharge valve during the heating cycle in a Baxi Luna 310 Fi boiler could be excessive system pressure. This can occur if the expansion vessel is faulty or not properly charged, leading to pressure buildup that triggers the pressure relief valve to discharge water. Checking the expansion vessel pressure and recharging or replacing it if necessary may resolve the issue.
