Mend SIME Super 90 Mk II Boiler Central Heating Pressure

How can I repressurise our SIME Super 90 Mk II?

We need to repressurise our SIME Super 90 Mk II as our central heating system will not fire up. Our hot water is fine but the pressure on our system is only about 0.3.

As i understand it, we need to let water in to the system? I am unaware as to which lever underneath the boiler this refers to...any help will be much appreciated!

You should look for the loop connections, somewhere on the inlet feed (mains) and the domestic heating pipe there should be a braided pipe to connect them both together.

the maximum presure should not exceed 3 bar and the minimum to run is 0.5 bar.

Hi, I just did mine by releasing the two valves, second from left and second from right, until the pressure was at 1, then tightening them again. I have to say I guessed the pressure as do not know what it shouldbe, any suggestions.
