We have a Greenstar 25Si/30Si. The water pressure guage is a little on the low side which means that we need to top up the water pressure. Can you advise us on where the filling link key fits in order to undertake this task. Thank you!

Remove the bottom plastic slide out cover of the boiler. The fill 'key' should be fitted to a stowage on the cover. On the underside of the boiler there is a squarish white plastic valve, then the fill loop opening immediately to the right (this is where you insert the 'key') and then a black plastic valve. Insert the 'key' into the vertical opening and turn the white plastic valve anti-clockwise until you hear water start to fill the system. Close the valve when you reach around 1 bar on the boiler pressure gauge. Remove the 'key' (there will be a little bit of water when you do this) and put the key and cover back into place.
