Gas fire flue requirements

[SPC]

While doing a job for a customer the other day she asked me for a second opinion on her gas fire which had been capped off. The other guy has quoted £900 to "sort" it and leave working. Now upon inspection of the flue, other than it not being supported properly I can't see much wrong with it. I don't usually work with gas fires but do have it on my ticket. I haven't bombed the chimney but am I right in thinking just support the flue correctly and if it passes the smoke bomb and all other tests with the fire on then it's good to go or am I missing something?

What is the correct method of sealing the ridge tile connector to the ridge tile extendor?

Self adhesive foam washer that comes with it.

High temperature silicone would do and use 2 x M10 nuts and bolts and a couple of penny washers.
