I am adding a concrete block foundation around a small cottage in Palmer Massachusetts. Next summer, we will re do all the plumbing during a bathroom remodel and at that time, install a tankless on demand WH (probably a small Renai unit). This unit will be installed in the crawlspace under the bathroom.
Does anyone know what clearance requirements for side venting might be? I need to allow for this when installing the block and when planning for the unit next year, as headroom is limited.
I hope to just leave a 1/2 block space (8x8 inches) open and to run the vent through this opening and seal around the excess opening. I assume that these units are "sealed combustion" with incoming fresh air and exhaust venting through the same coaxial power vent pipe.
Also, how far from a window does this side vent need to be?
thanks,
