Air trapped in boiler - help please!

in THE MAIN WALL
Hi,
I have a maxol microturbo 40h boiler. I think there is air trapped inside as it is making a terrible banging noise before switching itself off.

I currently have no heating or hot water!

I found an air vent at the very top of the boiler, so I bled this and only a tiny amount of air came out.

Anyone know how I bleed the boiler properly?

Thanks
Kim

    Which side of the \"pond\"

    do you reside in?

    That's a Brit boiler. How many pounds of pressure does the gage say?

    No problem,

    at least we speak the same language (sometimes)(;-o)

    One of the hands is pressure in atmospheres (possibly Kpa or Yank: PSI's), the other is temperature. If the boiler is piped properly, and not leaking somehwere, you should have at least 1 whole atmosphere of pressure, and with the boiler acting as it is, should be OFF, showing whatever the temperature is in the area surronding the boiler; 55-70F?

    An air "bleeder" should be on or near the top of the boiler as you already suggested. If the pressure is low, there's a reason for that, that needs to be fixed. You cannot bleed the air out (which you believe is the problem already - and are probably correct), until the water pressure inside reaches one atmosphere (14.7 Yank p.s.i)

    Perhaps a local service company would be the best bet?

    Let us know how it works out, please.
