If the boiler stops and a number blinks on the screen, read the number. 11 = no ignition: check the gas valve on the pipe is open (handle parallel to the pipe), then switch heating off and on. 14 = overheat cut-out: wait up to 30 min, then switch on again. 16 = water overheating: open at least one floor-zone valve on the manifold and bleed air. Anything repeating: call Rinnai A/S 1544-3651.
