Tankless heaters must be vented to the outside:
All models of tankless water heaters come with draft diverter
installed. Aquastar tankless heaters use conventional double-wall
Type B vent pipe. This is the same type of vent used with
conventional water and space heaters. Tagaki tankless heaters use
inexpensive 4-inch single-wall vent pipe, due to their power-vented
exhaust. Vent pipe is not included with the heater, but is easily
available at plumbing, building supply, or hardware stores. The vent
piping used with most of these heaters is larger than tank-type vent
piping. It is very important that you do not adapt down to an
existing vent size! Replace the vent and cut larger clearance holes
as necessary if doing a retrofit. Venting may be run horizontally as
much as 10 feet. Maintain 1-inch rise per foot of run. Aquastar
recommends ten feet of vertical vent at some point in the system to
promote good flow.
