Mend Riello 40 type 443T58 Oil Fired Boiler

How do I change burner nozzle?

My oil fired boiler keeps cutting in and out when cold. after about 10 minutes it runs ok. How do I get at the nozzle to change it? The boiler is a Boulter classic about 8 years old.,its burner is a Riello 40 type 443T58 which runs on 28 sec.Kerosene. The nozzle is covered in carbon and is inside a metal tube.

Remove the metal flame tube - but mark its position first! The nozzle is then revealed and can be unscrewed, but avoid moving the electrodes as you do so. The nozzle will be covered in carbon, you aren't advised to dismantle them (but you can do). If no improvement, have the fuel pressure tested at the pump. Normally they run at between 125 and 150 psi. If you replace the nozzle, get the same one by looking at the number on it example .60 / 80 deg means the nozzle will pass .60 galls of fuel per hour, at a spray angle of 80 degrees. The other letter(s) on the nozzle refer to the actual spray pattern of the fuel spray itself.
