Vent valve greenstar 35cdi compact how to get back inside

[diy_massacre]

Hi

Took the vent valve off which has a spring clip and sits in the top right hand side of the boiler, particular to this install it's in a cupboard making access difficult on top of a step ladder and sliding into the cupboard.

I have
Drained the system.
Silicone greased the new valve for reseating

It's difficult to reseat the vent valve and then get the spring insert back into position there must be a technique to get it back in and I don't have it at the moment. The U shaped retainer spring doesn't seem to fit over the vent valve body.

Any help would be welcome.

Many thanks

Matt

This is the space at the top right hand corner of the bolier

You shouldn’t be working inside a gas appliance unless your qualified

The old oring has been removed / came out with the old air vent ?

Looks like your oring is popping out so the clip shouldn’t be in there yet as it needs to go ontop of the lip not under it

Hi Shaun,

Thankyou for your response, it needed additional downward pressure with 2 finers before inserting the spring clip.
