Where are the closed valves on Ecotec plus boiler?

For EcoTEC Plus models, look below the boiler; there should be two grey levers which will have ‘closed’ written on them – each should be sitting at the ‘quarter to 3’ position (if it were a clock). Open both of these valves a quarter turn, so you won’t be able to read ‘closed’ – they should now be at the 12:30 position.
