boiler will not light on command

Postby revburger » Mon Nov 03, 2008 10:04 pm


Just replaced faulty diverter valve - drained system and refilled.

Boiler will now not light up when commanded by control box. Selecting hot water or central heating on constant or timed has no effect.

Boiler does flare up when first lit and if boiler thermostat is increased, it will flare up but not from the command console.

Have tried draining the system and refilling again ( with zone valves in manual open position and switched back to auto prior to firing up boiler )

Does this make sense - any ideas would be appreciated
