4.7 Fresh Air Kit (Optional)
Sufficient air exchange is necessary for the
fireplace to operate properly and to maintain
a good combustion. In an airtight household,
the fireplace may not function as designed
due to a lack of air; it is therefore
recommended to install the fresh air kit in
such cases. The fresh air system is an
optional kit intended to bring combustion air
into the fireplace from an exterior source.
Note that the FLAIR is designed to use a
minimum amount of air during operation.
Using an air exchanger or simply opening a
nearby window/door during the ignition of
the unit will achieve a similar result as the
fresh air kit. When the fireplace is idle, there
is no air escaping from the house through
chimney.
Consult a local authority having jurisdiction (such as the fire department, the municipal building
department, the fire prevention bureau) to determine if it is mandatory to install a fresh air kit in your
area.
General Notes:
The outside air kit should be installed according to the following guidelines:
•
The air duct must have an inner diameter of 4 inches.
•
The length of the air duct should not exceed 25 feet.
•
The duct should not be elevated more than 10 feet from the base of the unit.
•
Fresh air must come from the outside and not from another room or the attic.
•
The outside register must be away from automobile exhaust fumes, gas meters, or other vents.
•
Avoid installing the air register where it will likely be covered by snow or exposed to strong winds.
•
The air register can be installed above or below the level of the fireplace.
•
