Concentrator doing blow outs.

[FiredDesires]

I have an Alliance model concentrator that after 3-4 minutes of working time, the flame just goes out! Pressure is 4p/5lpm. no alarm sounds....just goes poof.

It has been 2months since the flood and I don't think there is moisture still hanging around, but maybe. Does the filter need changing or are the sieve beds trashed. Any ideas?

when the flame just goes out, does the flow ball stay steady in the flow meter?

I'll have to watch for that.....the meter isn't all that visible for me to see it happen, so I'll run it again Monday and see if it does and get back in here.
Thanks for answering.
