My Ravenheat CSI 85AT problem?

My CSI 85AT sounds like it is low on water, very noisy gurgling and stops and starts on firing up. the presure is at 1.5 bar and all the rads have been bled no air in, pressure stays constant Help?

sounds like air in your boiler. check that the cap on your auto air vent is open. look ontop of your boiler (top right) and unscrew the cap. it looks like a car valve cap. if the problem is air you'll hear a hissing from the valve and maybe a little water. dont worry this is normal. don't forget to top up your boiler after the air has been bled if required.
