How to increase pressure on baxi 105 he boiler?

[booey1]

Hey

The pressure on our boiler has dropped to the red and I want to repressurise it. How to I do that? On our old boiler you just turned the cold water tap underneath, but thete is no info on how to do that in the manual

It's probably pretty basic, but could any one explain in simple terms?

Thanks

Section 6.5 of the manual and fig 5

There should be a filling loop that was fitted when the boiler was commissioned between the cold water inlet pipe and the return circuit of the boiler. You're looking for something that looks like this.

That may have been removed once installation was completed. This will be needed to re-pressurise the system. It's a case of re-fitting the loop and turning on the taps until required pressure is obtained.
