Have you tried to wipe off the fire eye on the unit if it has one? If it's dirty too then it will not see the flame and not let the unit come on correctly. Good Luck and have a Happy New Year.

Fitted new oil burner riello 40 model g3b to a heatmaster 70/90 boiler. fitting the thermostat wires to the control box live and neutral keeps triping out the fuse box. any ideas;

If the pump has seized, this can cause an overload and blow the trip. Hopefully, that hasn't happened.
You can check by doing the following.
The pump and valve are normally located close to each other and may well be in your loft.
This webpage gives a few examples of what it may look like. motorised+valve&gbv=2
They are often in two parts, the mechanical valve and the electrical actuator and the two parts can sometimes be pulled apart.

If you can do this (don't try it if you are not confident with what you are doing), you will be able to determine whether it is an electrical problem with the actuator of if the mechanical part of the valve is jammed in one position.
Simply take the electrical actuator off the valve assy and switch the heating on again.

If the boiler starts up and the fuse doesn't blow then it will be the mechanical part of the valve jammed and this will need to be replaced.
If the fuse blows then it will be the electrical actuator or the wiring between it and the central heating controller.

One other possibility is the thermostat or the wiring to it.

Is your electric air shutter opening? That causes power to come on. Here's a link. don-ohio (:^)

Pilot light out....buderus furnace but a red riello ingniter on the front....I've watched my fuel guy flash a light into it this baby when out before but need to do it myself now.....could you walk me thru...

This is due to a "Lock-Out" Check your flame sensor for carbon build up. Possible heat exchanger blockage.
The reason he used a flashlight was to trick the burner into seeing a flame, not a good idea for a novice.

Riello oil burner RDB Hi everybody i have a Riello oil burner RDB . I am wondering is there a way to make it more oil efficient?

does it have the air damper installed? You can add a magic heater to the flue and dump heat into your basement.. thats maybe 5 to 10 percent more efficient

Good Luck!

Oil went too low, now don't start

There is a bleed screw on the pump, turn a 1/4 turn to the left, and bleed until oil is free of oil. On older pumps, instead or a bleeder valve it is just a plug, you will have to remove the plug, bleed, then replace the plug

I have a riello burner for my central heating system. When i turn the heating on the burner ignites for a few swconds and then goes out.... the burner tries to re-ignite and the same happens. I have...

Replace the nozzle, don't try and clean it. After the burner runs a few seconds, do you have to reset the control (red button) before it will start again? Does it sound like there is a pulsation in the flame when it starts or it is running out of oil? You may have a bad ignition control. Start with the small stuff, nozzle, strainer filter, oil tank filter and then work to the more complicated.
