s/s liner cap question

dp

My fireplace and boiler flues exit side-by-side through the same chimney. I just had a s/s liner put in the boiler flue. The installer removed my 14x26 s/s chimney cap (covering both flues) in order to put on the new liner rain cap, which stands too tall to put the chimney cap back on. Can I remove the new liner cap completely and reinstall my 14x26 cage to cover both flues? That seems logically fine to me, but I want to make sure.

Thanks.

Cap

Yes.

why?

Sure, you can but why? Those multi-flue chimney covers can cause flue gases from the heater to shunt over and down the fireplace flue. The liner will draw better with a separate cap. If you must put the big multi-cap back on, cut a hole for the liner, extend it with a section of stainless rigid through the big cap but keep them separated. You can also install a top damper on the Fp.
