Ideal Concord C 140 Series 4 intermittent pilot failure

[DBP]

Pilot lights stays lit, then main burner comes on for varying amounts of time then when main burner shuts down i believe the pilot goes out with it. any ideas?

Have you measured the INLET gas pressure when the problem occurs?

Trade questions are best asked in the CC part of this forum.

No i havnt been there when its happened it my mothers house, will be going tomorrow after work, strange part was i fitted a gas hob the day the fault occured, but only shut gas off then re-lit boiler. going to test for 240v across L & N on gas valve. Cant find documentation on boiler. works fine for several hours then as burner shuts off the pilot goes out as i believe.
