Anybody good with AGA's

[Mike2007]

Tried a few times to set up the oil valve on a two oven vapourising oil AGA and found the valve adjusts for high and low. Then when left the burner spills oil and carbons up! The level gets set to 3-5mm with new wicks.
Flue has been smoke bombed and oil line had suction pump on it. But always same thing with it looking good then stoppage due to feed problems??

What exactly is happenning? Is the burner overflowing ( spilling) or is it running out of fuel?
Have you altered the high and low screws?
Is it a manual valve, or electric thermostatic?

Its a manual valve and I set up the burner for oil depth, new wicks and light it. But it didnt seem go to high fire first time and eventually stopped burning.
So I thought if the level is correct and then flow rate is poor, so I altered the high fire screw to allow more flow to achieve high fire. This seemed fine, but the customer complained about the smell from AGA. The burning was spilling slightly and carboning up!

You are now overfiring the unit. You need to reset the flow rate to the prescribed level ( about 7cc for a two oven cooker). If the flow of fuel into the float control is good, no blocked filters etc., then your problem would seem to be the oil depth. 3-5mm is very low. The Aga spec is 6mm (halfway up the hole on the end of a hacksaw blade).
Have you also cleaned out the metering column? Have you checked the depth in the float control? Aga's are simple; do the simple things right and you should have no problem. A wise man once said to me the only part you have trouble with on agas is the nut on the end of the screwdriver used to alter flow rates!

Here comes an AGA Saga!!

Anybody got data on flow rates/ oil depth for cookers, AGA, Rayburn etc ?

See my earlier post. Do you have a measuring glass? If not, then a teaspoon is 5cc.
