Struggling to work out where to repressurise Flexicom30

[yorskshirebob]

Hello,
I've just moved to a new house and noticed my Glow Worm Flexicom30 boiler pressure is 0.6bar, so I thought I'd try to top it up. I'm a decent DIYer, and I've done this at my last house, so I went to try to find a filling loop.

However, all I can see on the underside of the boiler is something like the picture below which I found on the next. Only seems to be a in/out and no place for a filling loop.

Any ideas?
Rob.

Those are isolating valves on the flow and return pipes. There should be a filling loop somewhere. If this is a system boiler, it may well be in the airing cupboard.

thanks guys - the boiler is in the loft, and the water cylinder is in the airing cupboard with an expansion tank/bottle. I'll search for an alternate connection, but couldn't see one initially cos that's where I started before going to the boiler in the loft.
