Having a riser is not a bad idea, but I suspect something else is going on.

Re: what to do with this odd boiler vent setup redirecting the vent into the old chimney?
powervented cast iron boilers typically vent through a sidewall with UL listed stainless steel vent pipe, its a normal thing. yeah there will be local codes that regulate where your vent is located but I'm not entirely sure the current situation is entirely "up to code" either?

@Karl Reynolds is right .
Sidewall venting the CGI is the way to go. M

I hope this link works. If not, let me know. Yes, there are requirements regarding how close the vent terminal can be from windows, doors, fresh air intakes, etc. It's in the install manual for the boiler that I could send if you need.
Re: Drain boiler to repair some leaking pipes & pressure testing
if you go much above the operating pressure you may find leaks you otherwise would not have had

Re: Drain boiler to repair some leaking pipes & pressure testing
Just run the pressure up to 25#. That will be high enough, if you mess with the relief valve you may need to replace it.
Re: Drain boiler to repair some leaking pipes & pressure testing
Refilling with water and pressure testing — to no more than twice the relief valve pressure — not only is the most practical way to test — it's the safest. Pressure testing with air is really remarkably dangerous.
Re: Drain boiler to repair some leaking pipes & pressure testing
Your procedure sound like the best way to proceed.
Refilling is probably the only practical way to test.
Re: what to do with this odd boiler vent setup redirecting the vent into the old chimney?
Not the first chimney I've seen supported on floor joists. Not the best idea in the world, but so long as the joists are undamaged and old wood, and have a good connection to the walls, at least it won't fall down. Was it legal? Did anyone check? Probably not on both counts…
Now is it wise to use it for a modern appliance? Is it even possible to line it? It might be possible — but it's going to be a job, and the material costs will be at least comparable to running a nice new double wall flue up the outside of the building, and the labour costs should be less. Which is what I would do.
