Tankless Hot Water Heater Air Intake

Our furnace boiler intakes indoor air as currently installed so logic tells me i could do the same with the tankless water too.

Tankless hot water heater air intake.

The exhaust gases and excess heat produced by your water heater are then vented back outdoors.

However it would seem it would get plenty of combustible air from the room and i would likely never get a negative pressure situation because of the fresh air intake they put when the house was built.

A direct vent water heater draws air for combustion from outside your home rather than inside. I have the option to let our new tankless water heater intake indoor air it will be installed in a semi finished basement or intake it from the outside. And a tankless gas water heater might work great at 8 000 ft. What code would does apply in this case.
