Worcester oil boiler

[Mike2007]

Can a burner motor be working but still be a dud? I have a Bentone burner on a Worcester oil boiler.
Everything checks out, but the burner won't draw oil into the Tiger loop pipework?
Brand new pump and tiger loop. It all turns over but poor suction on intake port on oil pump.
Is the motor weak??

Or a poor joint between the tank and burner.

A leaky joint normally causes lots of frothing in the Tigerloop..

Have you checked the fire valve is not tripped or filters blocked.

Is the bypass screw fitted in the oil pump.

All checked.
I removed tank from equasion and connected tiger loop to a drum of kero.

Try dipping the suction hose into a container of oil. Do you have Pressure and vacuum gauges

Have you fitted a new drive dog. Are oil lines reversed.

It can only be something simple.

New drive coupling
New hoses
New oil pump + screw
New tiger loop
Deairator not priming (even with drum of kero)

Have you turned the burner isolating valve back on? Have you changed the hoses? If so, check the connection on the inlet hose and the isolating valve. If that is poor then there will be no frothing in the tiger loop. If you disconnect the pump inlet connection, can you prime the tiger loop with suction?

There seemed poor inlet suction on the brand new pump. This I blamed on broke drive dog or poor motor proformance.

If tank is a top entry , make sure pickup is submerged and the valve has not been turned off inside the tank.

Ok, its fixed. It was a concealed joint done by the installer.
Due to all the overwhelming nature of this task I am changing all my compression fittings to *flared*. Its enough of a ball ache using compression, without the fittings undoing themselves!
