FIREBIORD BURNER not igniting after running out of oil

byrneco

Hello all,

I recently ran out of oil and since getting a refill my burner isn't firing up. Sounds like it tries to get going every 15 secs or so, but immediately stops.

It's a Firebird Popular (C35kW I think). I've tried the following so far:

1) Turned allen key at the bleed nozzle until I got a steady flow of fuel.
2) Removed the little grey cap and hit the reset button on the grey box where the burn temperature is set.

I've got a Tigerloop cos the oil tank isn't higher than the burner. There's no foam in the tigerloop and it looks full of fuel.

Last fill I got the same thing happened and I called in an expert. He had the burner fired up in about 1min so I'm sure there's something simple I'm not doing. He also serviced the burner last time, so I doubt if it needs another service again now.

Any help/advice would be much appreciated.

Thanks,

If it's tripping the high limit stat oil is'nt your problem.
Check that there's water in the boiler, if there is check that the circulating pump is running.

"Stops" or locks out (Red light)??

If stops and attempts to relight check the photocell.

Sounds like there is still an oil feed issue, OP never mentioned the hi-limit tripping, only the burner reset.

There should be some evidence of fuel recycling through your tigerloop, with tigerloops you should not need to bleed your oil supply at all, just reset the burner a few times to get an oil feed, any airlock should be pushed by the pump out though the tiger loop.

Can you usually see a return froth though the tigerloop? if not, then the bypass screw may not have been fitted to the oil pump return line (and your tigerloop isnt really working for you) if you could always see it, then either your pump has had it, or there is a problem with the tigerloop.

All above are best guesses without enough information, connecting a pressure gauge to the oil pump tells so much more.

I suppose its how we read the op's post but i don't read it as them re-setting the burner re-set but the burner stopping, if the burner after stopping then runs through the lighting procedure again and again without it needing to be re-set then i would see that as a possible photocell issue.

He says he reset the high limit stat.

A failed PE cell will either cause ignition then after 5 seconds - lockout, or constant pre-purge with no lock out, no ignition, it will not cause the constant re-attempt at firing unless it's dirty and only partially 'sees' light

If the boiler keep re-attempting to fire (with a quick flame then out) it would either be a faulty control box or would be a fuel/air issue or even recycling of flue gas ( my usual first test would be air reduction, to see if it's over aired, then flue gas analysis to correct)

Don't forget your smoke test :eek:

Goes without saying (I like my FGA to work!! lol, CO cells ain't cheap)
