RETURN AIR
If outlets are placed in rooms other than that in which the
fireplace is located, a means of return air is required. This is to
equalize pressure and prevent back flow within the duct system.
This will also assist temperature regulation to these areas.
SECONDARY AIR INLET
Ensure the secondary inlet is connected to a suitable inlet vent/
grill.
