can someone please help. i have recently had a new vaillant eco tec plus 831 boiler fitted and my gas ran out. i now cannot get the boiler to light and f28 is showing on the control panel. could someone please suggest how i might be able to relight the boiler and restore my heating and hot water. i would be extremely grateful for any suggestions.

Its because the gas run out
Keep reseting boiler to purge air out of the gas supply
