A propane company installed a Baxi Luna HT 330 tankless gas fired combi boiler in my house 6 weeks ago. I noticed that the label reads "For use with natural gas only", but they claim it works well with propane too. I have had nothing but trouble with the unit. It runs O.K. for a while then goes out. It displays a trouble code E133 which I think means the flame keeps going out. The people who installed it can't figure out what's wrong with it. Do you have any advise?

See 5.5 on page 33

I hope they new what they were doing on the conversion and had the proper electronic tools to do the job correctly. The conversion is not something to just turn a adjusting screw on you have to have the proper tools.

Here is the diagram for your unit.
