Redfyre centramatic problem

[Terrywookfit]

!/4" solenoids are no problem to source should you need one.

Flue stat lives under the top casing cover.

I also have an igniter BNIB if you need a spare.

Hi Terrywookfit,
Great, I'll check things out and yes, if you have an igniter I'll have that off you as I only have one new one left.
cheers

Daughter called last night and said boiler was on lockout and heavy smell of oil.
The pot had quite a lot of oil in it which I pumped out.
I changed the ignitor which was gunged up.
The boiler fired up straight way but I guess there must have been quite a bit of oil still in the pot because the flames were coming back towards the fan and bellows of smoke came out. The boiler severely groaned for a bit then settled down.
Why do you think there was so much oil in the pot?

How many attempts at relight were made from lockout.

Hi Terrrywookfit,
thanks for quick response.
Don't know and I guess I didn't ask - more thinking of getting it back on and heading back home for supper!
I guess if she kept trying to switch on it would keep putting oil in and once the ignitor was "soaked" then there would be no chance of lighting. The ignitor looked pretty manky when I removed it.
Seems to be working ok at present though.

Anyone have a wiring diagram for a centramatic 50?
The orange light comes on but nothing happens.
I took the cover of the "control box" and there is a solenoid to the right. When I pressed this closed everything started working so I'm thinking its an electrical problem.
Also, there is a fuse on the right which looks like it has some fuse wire shunting it. What is this fuse for and can they still be sourced?
Many thanks

Amazing that you still had one of these still working in late 2020 !
I used to service a Centramatic 40, years ago for a friend (actually it was about 40 years ago as well haha).
I remember being appalled that it burnt paraffin with a totally yellow flame (unlike natural draught pot burners that can burn paraffin with a blue flame **) but I was impressed at the quality of the rather strange water tube boiler arrangemet that was built to last.
As you will know these boilers would get quite sooted up after a heating season and I remember Trianco Redfyre Technical speaking of the burner going through a `smoke curve' on start up (because the burner isn't totally suitable for on / off operation; the oil comes into the pot at a fixed rate before the fire has properly established (pot has to warm up), resulting in over fuelling on start up).
** The Portakabins at my Secondary school in the late 60s had Oranier oil fired convector stoves for heating, it could be seen by a peep hole in the top that the pot burner was producing a blue flame, unless turned up too high when then the flame became yellow. Oranier are still going but have dropped their oil fired stoves.
N.B. There is a Worcester Dynaflame 50 still in operation in the UK btw, it's on YouTube. This had a blue flame burner made by Howden in Scotland and was an improvement on the American Wallflame burner (made by Timken) of the late 40s (US) and 60s (UK).
