britony se 80. pressure should be 1.5bar.the loop is under the boiler joining the incoming feed to the central heating these are the 2 last pipes on the right.open valve on this pipe until 1.5 shows.if you have lost pressure you may have a leak.no flame detection means the ionization electrode has not detected a flame.maybe electrode has failed (£40) or pcb has failed (£130+). leak needs sorting to see if 70 80 fault goes.when power is isolated elecrode contacts can be cleaned and pcb checked out.
