#Plumber Fault Finding. Gas Breakdown Training. How to repair a Gas Boiler. Always work as per TB118 and the manufactures installation instructions Changing a gas valve Roy Fugler
Loved this one 👏👏👏 brilliant work Roy from viva and Allen 👍 Looking forward to future vids. Water / air / gas / electric…..didn’t know what wage was before this …..can’t earn a wage without using this format 👍
Once again another great video keep them coming its priceless m8 top men the pair of you should both be given a knighthood not forgetting mr ideal and the other chap .
On a couple services for Worcester greenstar boilers, after I turn the gas off to check the flame failure device. An fo 238 internal error code comes on the boiler screen. To my understanding a new gas valve is required after some check, how can turning the gas off break the gas valve?
Could you do a video on how to wire up a regular (heat only) boiler with pump overrun when replacing an older boiler without pump overrun with a newer condensing boiler.
Back voltage on a Worcester who’d of thought it! 😂 Lovely job. What affects the air integrity test. Obviously seals ect but hear height can reduce the oxygen level Just to add I’m pretty good at my job but always looking for tips like any half decent engineer would be. I’m sure lots of experienced guys watch your stuff!
Hi Alan, at last, Roy said he will do video on wiring unvented cylinder and s plan, is there video done for it, if there is can you please put me the link.
Terrific video as always. Just a couple of questions, could you not have just changed the solenoid and my other question is when I change a gas valve on a Vokera I have to adjust the gas valve in high and low fire but not here? Thanks
Hi Michael, Thanks for the feedback. Unfortunately the solenoid isn't available as a spare part, Worcester gas valve comes factory set, so just a case of checking to make sure it's within tolerance. Baxi use a similar SIT valve and they need adjusting the same as Vokera.
A blocked condensate trap backing up into the sump will cause resistance on the fan, which in turn cannot lift the valve seating and therefore no drop on the gauge. Never never assume without proper testing.
