2.2 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 (see Figure 5). The combustion air control of the
FUSION 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 FUSION is in operation. Use the Cold Hand Key (see Section 2.3) to adjust the Combustion
Air Control.
2.3 Cold Hand Key
The Cold Hand Key (Figure 6) is an accessory that comes
standard with the FUSION insert. The Cold Hand Key is a
tool used to manipulate the Combustion Air Control Levers
(Figure 5) when it is hot.
2.4 Secondary Air Control
The Secondary Air Control (Figure 7) is a patent pending
mechanism (Patent Pending No: GB1307428.1) that
automatically regulates the amount of secondary air in
accordance to the temperature of the FUSION to create a
unique arrangement of natural and appealing flames that
prolongs the combustion, increases the efficiency and
reduces the emissions of the fireplace. The Secondary Air
Control is factory set and requires no intervention from
the user. The Secondary Air Control is located at the top
of the firebox and releases secondary air through the
perforations of the baffle of the FUSION.
2.5 Chimney Sweeping Cap
The chimney sweeping cap found at the baffle of the FUSION
allows easy access for chimney sweeping without having to remove
any components of the firebox (Figure 6).
WARNING:
The chimney sweeping cap should be blocking the
access to the chimney at all times during combustion. A chimney
sweeping cap that is not blocking the baffle hole during combustion
is a safety hazard, will overheat the fireplace and void the warranty.
