Combi boiler and heating

[bgbuild]

Can anyone help with this please. I have a Ravenheat 85csi combi. Its just been installed, pressure on water 1.5 bar it ignites runs for 30=60 secs and then locks out with red light on?

Certainly get the installer back, as it's under warranty.

I would love to, but in Bulgaria you can not get a proper gas person. Someone fitted it in the summer when i was not there and i have only found out about it and the person is not around until next year

Has it ever worked?

Are the flow and return valves to the central heating open?

Take the cover off and remove the centre screw from the pump.
When the boiler is running put a screw driver into the hole is the pump
turning?

Does the boiler start to get hot?

Is the gas valve open?

Do they have the same pressure of gas in bulgaria???? Or is it LPG?

I went to bulgaria. Nice place looked for houses but everywhere I went
there were nice places that where surrounded by the run down houses and bulgarians around them. So decided against it.

Maybe there is an opening for me as a gas engineer in bulgaria.

Yes pump is turning, boiler starts to get hot, so do heating pipes and hot water when tap is turned on and no it has never worked what i know of. it is lpg and yes the gas valve is open, i believe the lpg pressure is 34.
It does depend where you go about the propertys.
There would be an opening for you.
thanks

May be that the gas valve is not correctly set up

Does it work on central heating.

Check all air bleeds in the boiler and that the air bleed at the pump
is open.

Is the pressure guage just above 1 with the boiler cold.
Does the pressure gauge go up and down when the boiler starts
to run?

Could be the lpg jet hasn't been fitted? Or the gas valve hasn't been
adjusted for the lpg.

it does seem by the sounds that it could well be the gas valve, i will try a pressure test on the system and see if not could it be the Overheat thermostat although it is a new boiler?
Thanks

If the boiler is getting hot you will hear the boiler getting too hot.
popping in the heat exchanger.

Unlikely to be the overheat thermostat.

Check the regulator pressure you have on the lpg there should be 37mbar.
