can someone tell me if it’s code violation to takedown/remove interior masonry of existing/non used chimneys within my attached brick townhouse?
would like to vent new boiler (mod/con) to roof with PVC behind chase wall, remove the brick footprint of the chimney and have a square room. I would re-brick the exposed area to match flush with the existing wall. any code problems with this?
thanks
2100 sq ft x 9.5′ avg ceiling height x 4 (rule of thumb multiplier for typical BK attached masonry construction, with design temps maintaining 70 degrees indoor at 10 degrees outdoor) = 79,800 BTUs output.
So, yes.
But there could be something else going on, so I guess I don’t really know.

MP,
would you consider the ultra 230 oversized for 3 story single family (2100sq’). used with a WM indirect fired water heater. I know there are a ton of variable but as far as heat loss- I don’t know what it is. There will 11 total radiators over 3 floors, WH will service 3 bathrooms. just looking for quick thoughts before this unit, which is at my house is installed.
thanks, of course.
Honestly, I want to say yes but trying to satisfy the codes for venting condensing boilers lately has been like trying to shoot a moving target.
I assume you’ve got an architect? Let him/her speak to their expeditor or engineer to see what this month’s requirements are.
As for the Weil McLain Ultra Series 3: It’s a very good boiler. I’ve installed several this year with very few problems at all. Piping, sizing, wiring and pumping are all critical though.
I see many of them in the field that are just a mess, so make sure your plumber is up to the challenge.
jock, I have permits for renovation with minor structural work and relocation of all plumbing, etc. it’s a gut reno.
MP, can I encase it in 2hr rated material all the way up to satisfy code. Also, how’s your experience been with the Weil McClain Ultra 3 series? Any pitfalls to share?
thanks guys
It’s a code violation if that’s all you do. The PVC vent has to be in a (2 hour?) fire-rated enclosure.
yes, you would need a permit for that. It is a structural item.
