Gap around the hole flue exit; Plumbers Forums

Hello there

Quick question: I have installed a new boiler today. The engineer is foing ro back tomorrow.

The boiler is in the conservatory mounted on the wall. The flue pipes exit from top of the boiler through a round hole to outside the house.

There is a big gap around the hole and wondering if this is how it should be or should I ask him to plug the gap?

Also he has installed the gas pipe (gas meter to boiler) outside the house. Should I ask him to insulate or any put something on to protect from any kind of damage?

Thank you.
