As far as My end goes annual CSD-1 and backflow testing and Cleaning of each boilers heat exchanger. Building maintenance must visually inspect once a month

Those 4" flues are fun. Did some on a triangle tube boiler.

Yeah the best part of the venting was dropping 35' of 4' sch 40 down the existing chimney 4 times to direct vent each unit. There was no place to sidewall vent.

Looks really nice
Are those redundant pumps? Or are they both used together?
