    Gas pipe sizing issue

    Thanks very much for the replies everyone. Certainly seems like I'm between a rock and a hard place. Been glancing at electric boilers over the past few days :( One plumber has quoted for an Ariston 24 E which he says should be ok with the reduced pipe size. I guess there's no way of knowing...

    Gas pipe sizing issue

    Evening all I'm in a real fix and would appreciate some expert advice. Almost two weeks ago my ~20 year old combi boiler decided to throw its toys out of the pram. Fair enough, I thought, it's finally time to get a replacement. I've had a few different people call and they've all sucked...

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    so much for that. Seems like a very intermittent fault. I replaced the high limit stat and all seemed fine for a day of use but this evening it's crapped out again with the same symptom. Have emailed a couple of installers so hopefully I'll have a new boiler asap... Thanks for your advice and...

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    After triple checking the fan and flu connections I turned to the circuit diagram. As far as I could work out the only thing that would cause complete gas valve shut off (burner and pilot) would be the thermocouple and high limit thermostat. Is this correct? As I'd already checked the...

    Hi DP Replaced the fan as per the service manual instructions. Followed to the letter. Pilot...

    Hi DP Replaced the fan as per the service manual instructions. Followed to the letter. Pilot swirls when electricity is switched on and what I think are swirls are seen when burner is on. Fan definitely runs at slow speed when idle and then switches to high speed when demand for CH or HW. Thanks, J

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    hah! phew, it's not turning :) The flow pipe gets hot but the return pipe remains cold, presumably because it's not had chance to circulate back into the boiler before the burner shuts off? I held on to the pipe on the r/h side of the main heat exchanger where the cut off thermostat lives - it...

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    What's the easiest way to confirm the pump is turning? When looking at the pump, is the thing that looks like a large flat head screw supposed to turn when the pump is on? Thanks

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    Here's what I actually ordered: http://www.euroboilerparts.co.uk/fa115-ferroli-39803860-vokera-4923-3434-206-p.asp Quite a price difference and it doesn't have the additional plastic cooler either. I now see the 3434 product code - I originally found it by simply searching 'rs turbo 20 80...

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    The new fan has a metal blade which looks like it's designed to cool the fan itself. This is between the fan body and the metal housing. Let me see if I can find a pic...... Identical to this one above. I found it by google image searching 'vokera fan' so I've no idea if it's the correct...

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    Thanks for the advice. I ordered from a place online. Stupidly I threw the old fan away but the new one was ordered as being for my model. I'm not sure of the product code but the label on the fan states: M-V-L RLA97/4200 3030LH-92 Is that any help? I feel rather stupid for throwing the...

    vokera 20/80 rs turbo burner and pilot suddenly shut off

    Hello I was wondering if anyone on here could offer me some advice? My old vokera has been serving me for many years now but recently it developed a problem with the fan whilst I was on holiday. I came back to what sounded like a bunch of spanners in a washing machine. The fan was found to be...
