Clear picture of area you are dealing with would be useful Your overthinking folding. Dog eared corner like this takes seconds.

First have you tried reseting boiler? As its a system boiler your going to have 3 port motorised valve or 2 two ports. To check if you actually have a switched live to boiler your going to need a multimeter and be competent to use it.

As above but I would recommend the mcalpine FGT150-110 floor gullet Full 110mm bore no water trap very easy to fit We have installed a fair number in commercial kitchens with zero problems.

Pipe on left appears to be heating flow so arrow wrong way round pipe on left looks like old cylinder return.

See pic open vented on a H section did one last week even worse but that had a airjec fitted .

Internal easy just a folded dog eared corner external needs bossing or we would just leadburn both. Yes needs either to be turned into wall or cap flashed. Clear picture would be useful.

15mm is fine behind dot and dab it's only 5mm beyond 10mm Plus 15 is what's use for h&c and that goes behind dot and dab as well.

Your fga should be fine just select correct fuel!

If motor bearings have gone (nearly always pump side) they can be changed just a strip down job. We now just replace motors to save customer come backs. If it needs a new pump If you haven't already got a oil pressure gauge get one to set pump pressure. Then analyse flue gas to fine tune...

Air admittance valves can only be used if drains are adequate vented elsewhere.

As above Saxton blades with me they do get trade use and abuse!

As above re boiler size I'd want to look at heat loss calculations. They both seem to be offering what would be regarded a a fairly standard S plan system. I would at least look a better controls and a boiler capable of hot water priority that could keep boiler in condensing mode most...

Just spoke to my sister (she's a Dr of horticultural and lectures for R H S) She recommended looking at R H S website they have several pages on box moth . Also a reporting form that is helping keep track of the spread.
