Refleks stove old style toby valve

[hori]

Hell all, My Refleks diesel stove, I believe is 61 MS. It has the heating coil for rads. The stove has been trouble free for years and recently has been giving problems. I have cleaned the toby valve, old style and it has new fuel filter from my tank and clean diesel. My flame is yellow with hardly any blue. I kinda recall looking down the peep hole and it having some blue. I adjusted the high fire today, 1.5 turns in clockwise and the flame never really changed and not blue. What am I doing wrong and why dont I have a blue flame?

Do you have a big yellow flame (up around the coils) or a little yellow flame (down below the coils)?

Did you clean the pipe from the Toby valve that lets fuel into the stove?

Reason I ask, when you routinely scrape the bottom of the burner pot it is easy to push small amounts of the slag into this pipe if you don’t block it with the thing that looks like a tent peg (used to keep the oil orifice clear of slag). This will eventually buildup and choke the fuel supply.

Also, yellow flame could indicate an obstruction in the flue causing the oil not to burn properly.

If the fire has been good in the past, there should be no reason to go near either the high or low adjusters - the fault is sure to be elsewhere.

From my limited experience with a 66M before some scum burglar stole it (while it was alight!) they do coke up around the cleaning bar area (tent peg) and the base of the burner pot. 

 

Taking the top orf and breaking up the soot deposits in the bottom then sucking it out with a vacuum cleaner seems to be the thing to do. 

 

Also there are some small holes a bit further up all around the side which apparently need to be clear to a certain size. 

 

I only used one of these for a few months and it got stolen and I didn't think it was all that great but yes it does need cleaning.

Cleaning bar!! That’s the words I wuz looking for - although it does look a bit like a tent peg........

Toby valve totally cleaned, fuel inlet and cleaning pin all clear. I would say large flame just below coil.

Have you moved to a different mooring? 

 

If there are tall buildings around it could interfere with the draught. 

 

Possible that the flue and/or external terminal may be partly blocked by soot.

 

Flue blockage is interesting. If the flue is 4 inches (100mm) in diameter then every millimetre of soot deposit on the inside will be a 2 percent reduction in diameter. If the soot were to build up to 5mm on each side, which is plausible, this would be a ten percent reduction. 

 

This sort of thing seems very likely to negatively impact the draw and affect the flame.

Not only because of the reduction in diameter but also because the flue which was previously a clean stainless steel thermally regular surface is now an irregular surface both thermally and in terms of the cleanliness. 

 

I think it would be worth looking at the inside of the flue and the terminal.

Large yellow flame suggests fuel is getting through but it is not getting enough air. I would be gently wire brushing on the inside, then putting a mirror on a stick down there to see where all the holes should be and poking them out with a needle. This is a somewhat regular requirement for our 66M.

It will be the row of very small holes round the bottom of the burner pot that need cleaning.

Seem to remember it needs a 1mm drill bit between thumb and forefinger.

There is a Reflex owners help forum on Facebook.

The people on this forum know everything (almost)  😜

but more specialised knowledge may be more helpful.

I have been trying to join that facebook for for weeks now?

I was out of cleaning tablets so I got some and will try today.

 

 

 

 

I am missing the cast iron two piece top burner ring,  It was like that 5 years ago when I purchased and never new otherwise. Is the burner ring for 61 ms same as 60m ? they look the same?

Keep trying!

Sometimes the moderators ( if that is the right description)on Facebook goups don't look in that often.

I posted a question about Enfield Outdrives and it was six weeks before it appeared.

That was certainly the case with my Kabola Old Dutch when it suddenly started burning with an orange flame a couple of years after I'd adjusted the high flame screw to get a nice blue flame.
