Pilot lights but main burner intermittant. I am told that if the shroud over the pilot is corroded a new one might ensure signal to pass through the pilot flame to actuate the main burner solenoid! Is this correct. A new shround is relatively inexpensive but would take some time to fit! However, suspect a new valve will be neccessary.
Thanks,

there are several types of netaheat 16/22. you are barking up wrong tree with pilot hood. these boilers need to be checked by pros as they can become DANGEROUS

Nothing to do with the pilot hood........
A good gas engineer will fix this fault in a jiffy.
Remember Tony in this country it is ILLEGAL to mess with gas appliances unless qualified and registered.
use a pro and check his CORGI ID he will have it with him if he's legit...
