Most appliances require a minimum stack height, typically 12 to 15 feet.
Check the appliance manual, as this measurement could be from either:
a) the floor of the appliance or b) the top of the appliance.
This measurement includes the vertical stove pipe and insulated chimney.
The shaded grey cells of the calculator below have default values pre-set. Change the default values (press enter) to match your appliance and installation.
The stack height that is needed to compensate for changes any in elevation, elbows,
horizontal sections, offsets or tees used in your installation will automatically be calculated.
