How to increase pressure on Worcester 30 HE

[yelf]

My pressure is below 1 bar when cold. The manual just says "increase the pressure by doing what the installer showed you". Great.

on other boilers there have been some easy to adjust valves to do this. But I'm not 100% sure on this boiler. Any suggestions please?

Thanks

there should be some valves in your airing cupboard

Ok thanks. I've found a tap handle on one of the pipes in the airing cupboard. I assume I open this to increase the pressure? Seems odd that I can't see the gauge whilst doing it

its usually a little black handle on quarterturn valve 'usually' its on a flexi braided pipe..
turn it a little, check the gauge, repeat until satisfied.
