I. INTAKE AIR

This fireplace has options of air intake connections on the side and the bottom of the fireplace. Use chart in Section 8A to determine which size metal

pipe you should use for your fireplace. Connect only to metal intake pipe or approved flexible pipe. Insulate all exposed pipe against cold air/frost.

The intake pipe must maintain 1.5X the square inches of the flue pipe in free area. Intake screen/vent must be sized appropriately. Failure to do so

will result in higher operating temperatures.

The fireplace may also take room air for combustion. Intake screen/vent must be sized appropriately. You must plan for the replacement air that is

consumed from the room by the fireplace.

Use the table below for reference on CFM replacement air if drawing air from inside the house and open air requirements for intake screen/vent,

or consult Hearth & Home Technologies directly for more information.
