2.3 Combustion Air Control
The Combustion Air Control is a patented mechanism
(Patent No: US 7,325,541 B2) that regulates the air
flow into the firebox based on the temperature of the
unit. It is located on the top of the firebox, at the front
center of the unit. The combustion air control of the
FLAIR has two components: the Activator and the
Burn Rate Selector. The left combustion control lever
is the Activator. When starting a fire or adding a new
load of wood, the Activator must be pushed in to allow
a primary source of air to enter the firebox. The
Activator will retract automatically with heat. The right
combustion control lever is the Burn Rate Selector.
The Burn Rate Selector can slide sideways to achieve
different burn rates. When the Burn Rate Selector is
positioned to the left, a maximum burn rate is achieved
and when it is positioned to the right, a minimum burn
rate is set.
WARNING: Never manipulate the Combustion Air
Control with bare hands as it gets hot when the
FLAIR is in operation. Use the Cold Hand Key to
adjust the Combustion Air Control.
2.4 Baffle Secondary Burn Technology
The baffle system (32SF1150) of the
FLAIR insert is located within the upper
portion of the firebox and is fastened by 6
bolts (3/8 Hex). SUPREME baffle systems
are constructed out a specific grade of
stainless steel capable of withstanding
high-temperature
conditions.
The
secondary combustion air is drawn into
the baffle system, pre-heated, and
distributed below the lower plate, allowing
for a cluster of small flames flowing
downwards. This effect is more visible in
the minimum burn rates. For optimal
performance, it is recommended to clean
any creosote build-up on the lower plate
of the baffle system.
2.5 Cold Hand Key
The Cold Hand Key is an accessory that comes standard with the FLAIR insert.
The Cold Hand Key is a tool used to manipulate the Combustion Air Control Levers
when it is hot.
