Glow-Worm Fuelsaver 30B Mk II

[GQuigley67]

when to see this boiler today as it wasn't working, its an old balanced flue conventional boiler, pilot wouldn't ignite, i eventually managed to get it to work but when i did it wasn't really in good condition, with the casing off when I fired up the burner the flames would burst out from below the burner and come up the sides of the combustion chamber, also the flames were really orange and yellow, signs of scorching on the outer casing, I ID'd the boiler because the casing was leaking POC's as it needs new seals.

my question is why are the flames bursting out ? it also stinks of gas when in operation, with the casing on you can't tell if it still does this but without the casing on it does not look safe, I didnt have my ladders with me today so couldnt inspect the flue.

also there was no ECV in the flat, gas meter was outside and not easily accessible unless you jumped a fence for quickness, I AR'd this but was wondering if I was right ?

Ballance flue boilers will do this with the case off Gerry they have not got a mechanical extraction fan so outside air pressure cna force the fumes backover into the burner compartment. With the case on this doesn't happen as there is no pressure difference placed on the flue outlet and convection takes the fumes out! 🙂

Your right to turn it off though if the case seal is perished 🙂

that's what i thought just wasnt 100% sure bit hungover today lol, going to fit new pilot assembly, seals and give it a service on monday

As diamond said they do that with the case off. The yellow / orange flame would have made me check the heat exchanger didn't need cleaning. It might have been choking itself out. You can check the flue from inside by taking the wing nuts off the top hood. They are usually starting to rot by now. It is about 25-30 years old.

Yeh nice one 🙂 Dodgy seals allows air to pass from outside to inside and will also upset the ballance of the boiler and effect combustion 🙂

so if there is no AECV in the Flat is this classed as AR ?? you would need to walk more than 6m to get to the gas meter

 

[GQuigley67]

also anyone got the manual for this boiler ?😛

 

[diamondgas]

AR if there is no adiquate access to the ECV according to GIUSP --- 5.7

I'd assume that means NCS if there is adiquate access to the ECV .. If otherwise working fine and they need to use there gas for cooking etc I'd leave it on and advise that they have an AECV fitted.

Got mi's for the GW ufb 30B I think it's the same one, GC 41-319-32 🙂

I've got the mi's for the fuel saver 40b Mk ii, if you want them.

I draw your attention to BS 6891:

8.17.1 An additional emergency control valve (AECV) shall be fitted:
a) to the installation pipe where it enters the building if the meter is sited 6 m or more away from the
building.

Wither it is 'AR' would be down to your interpretation of how readily accessible the ECV would be in an emergency situation.
If the tenant would have to run down two flights of stairs and unbolt the backdoor and run 10 meters to meter box then that would be 'AR' in my opinion.
This would not be readily accessible in an emergency!

But, having to walk 10 meters form a ground floor flat to access meter would only be 'NCS' in my opinion.

Here is the manual for a 60. The same stuff applies to a 30 and the data plate on the boiler will tell you the burner pressure settings

There is nothing to them.

I'd probably class the ecv as ncs unless the meter is behind a 6ft fence with a locked gate.

unless you wanted to risk braking your ankle jumping down to the gas meter to turn off the gas which you had to decide which one out of the 6 was your flats then i would suggest that it wasnt ideal for an emergency situation, but that was just my view on the situation i highly doubt anything will be done about it anyway
