If the boiler is full of water, the cover removed outside, the gas is on at the bottle (and any manifold) and you have 12v power at the boiler.
Turn the switch from the center to either position, at this stage nothing will light up, but the boiler should start to heat up, if there is a fault (gas, ignition or vent) the red light marked ‘a’ will illuminate.
The water will take a good while to heat up and even when heated can take a good few seconds to actually reach your tap from the boiler.
