rayburn with don oil conversion burning high

[azza1964]

The burner flame is very high (and yellow) causing the top baffle to turn red! It was serviced only a few weeks ago and initially the flame was burning fine. I am worried as the rayburn provides central heating and now cannot be left on for too long as it overheats.

Any ideas or solutions would be very welcome.

Get your service engineer back. Either too much fuel flow, or the burner depth is too deep. The float control may have failed and lost its level. To a competent technician, these are simple.
