How to vent my glowworm ultracom 30sxi

[Devon Dave]

Hello helpful people.

I have a leaking safety valve, the system is losing pressure over a few days. I am about to replace it but after draining and fitting the new valve the instructions in the manual say "refill, vent and pressurise the boiler"

My question is: how do I vent? I see there is an automatic air vent above the pump, but the is low down, is there a vent at the top that I should do something with, or do I run the pump, if so how do I stop the boiler firing up? Or do I crack one of the compression fittings on the heat exchanger?

Thanks for any help.

This plumbing forum will not provide advice to anybody with regards to boiler repairs or any other form of gas plumbing without you first providing us with your Gas Safe Registration number in a thread - for very obvious reasons. If you're not qualified to touch gas, you should stay well clear of trying to!

It's water, I'm not touching any gas fittings.

Thanks.

You're opening the boiler to get at them. This is illegal unless you are a GSR.
