Drip Feed Method?

[jls]

Hi All,
Can someone enlighten me to what exactly the "Drip feed method" is when it comes to measuring the oil feed rate of a Rayburn 368K? I've searched the net and asked oil engineers and I can't find any reference to such a method other than in the Rayburn installation instructions

flow rating on a vaporising appliance is carried out by measuring the rate of flow from the oil into using a measuring cylinder usually over a period of 3 mins to give an accurate assesment of the fuel rate . On the cooker side it will literally be a drip feed with 4cc at low, and 13 cc at high will give a fairly rapid drip. The problem however is that when the appliance heats up the oil control , then the carefully set rates will change and you may have to adjust again for a decent flame picture.

Boiler side of a 368K is mega fiddly cos you have to have a 240 v supply connected directly to the solenoids so better to adjust based on flame picture
