Hi,

Hoping someone will be able to help. Have a Halstead Finest Gold and I have had the heating on tonight - just turned it off and the burner is still lit (some 20 minutes later). I have turned off the boiler at the plug (only way to turn the boiler off) and turned back on after 5 minutes but burner still fired up and stays on.

Anyone have any suggestions - I don't have much knowledge with these things just looking for some guidance!

Thanks.

One of your mororized valves is faulty.
In your m/valve is a axcillary switch the grey wire is your feed and orange wire is your switch wire to boiler
One of your axcillarys is jamed open and thus sending power to ur boiler even when your time clock is off.
Very common problem
To fix you need to replace one of your motorized valve heads.
