Neataheat MK2 gas valve prob

[GasWorks]

Hi all, just wondered if anyone can help with any information on the gas valve on the above NH MK2? For my sins I have been asked to look at this boiler for a friend, now we all know favours cost you money but I still said I'd have a look..... Well so far it's cost me £140 for a new Mercury switch, I know I should have checked the voltage at the gas valve connections but didn't have my MM with me so couldn't. So now I get 230 on wire 1 when pilot established and then 230 on wire 2 when MS has proved so looks like main gas solenoid is shot. I have been looking through the Neataheat posts and there was some talk about just replacing the solenoid coil, is this possible with this valve, I have done it on various other valves but this one is all enclosed. Any help would be greatly appreciated.
I would have post this in CC but my card is in my van and I need a quick answer Ta

is this possible with this valve,

The solenoid isn't a spare part, unfortunately.

Thought so, must be the later valve that everyone is talking about replacing the solenoid. So now I need an obsolete valve that people are charging silly money for......

 

[ChrisR]

Er, no, none of the Netaheat 2F valves had officially replaceable solenoids.
The boiler's had its day, really, at 25-30 years old. I put mine in 28 years ago, & wouldn't spend any money on it now.

I know I should replace it but as it's a friend they will want it done for next to nothing and the whole system needs bringing up to spec. If it wasn't the mother of someone that gives me 50% of my work I wouldn't even entertain fixing it. Ho hum...........

It's a long time since I've worked on one of these - but, have you checked that you've got 'a really good pilot flame?' [quote from Pott Tech]. I suppose that if the mercury vapour switch is operating, then you must have, but it's worth a look.

 

[GasWorks]

Yeah, if it wasn't for the fact i get 230v on the out put to the main solenoid then I would agree. I will have to bite the bullet and get a gas valve. The annoying thing is, some where I have got one of these valves laying around but as you know, fitters aren't the tidyest of people, well all he lot I know aren't!! i'm going have a root around in my garage now and see what I can find...........

If the Customer is responsible for 50% of your turnover I would think that you could "loose" some of the cost of replacing the boiler against other projects from the same customer??

You'll be doing well to find a valve for that old crock!!

p.s. I would be very nervous having one client representing 50% of my work-load!!

Is it this valve.

[GasWorks]

Yep, thats the little bugger. Now that wasn't on there last night when I was looking! On the other subject, it can be a little worrying at times having half my eggs in their basket but the money is good so i'm not complaining. I just hate changing boilers, done so many of them when I was an apprentice, and a lot being the early Neataheats and Mexico's that now I just like the maintenance side of things........

 

[corgiman]

would you really chance buy a gas valve orf ebay??

 

[tamz]

I really need to get into this ebay stuff and sell sh...........cartloads of junk that might be of use to some poor c........person in need
