Induced Draft Fan.


If the unit is LP or Natural Gas fired, the pipe should terminate at the home exterior.

I agree. It is a gas unit, I’m just wondering what they were trying to do with that thing.

You’ve got that right.


They have a furnace (also gas) chimney that is so badly corroded that there are pinholes in it inside the attic space. It's a good thing that this house is in FL. The furnace doesn't get too much use.

Also, the vermin have added quite a bit of ventilation by chewing some well placed holes in the walls.

This is a power vent water heater, it eliminates the need to have a chimney vent or a flue thru the roof.


But it still needs to terminate thru an outside wall and maintain clearences from windows, doors, etc.

Most of them are equipped with a 24 volt air pressure switch. The unit will not begin the ignition sequence until the direct vent fan system is up to normal operating speed. Great question Jae!
