Lennox International Inc. MONTECITO ESTATE MONTEST - Manual (Page 4)

The combustion air control should be opened
before opening the doors to minimize the possi-
bility of back draft coming into the room (Figure
1-A) More details are available in Refueling For
Best Performance on Page 5.
Time Delayed Air Boost System
The time delayed air-boost system register is
located underneath the door handles. Placed
in the fully opened position, a timer with a
maximum duration of 2 hours is engaged. The
register gradually reduces the amount of air
injected, allowing for a better start of the fire,
whatever the conditions (See sections Building
a Fire and Refueling For Best Performance for
proper sequence of operation). This allows
you to start the fire, set the primary air control
to the desired burn level and the fireplace will
automatically adjust itself to that level once the
fire is fully established (Figure 1-B).

Accelerated Combustion
The maximum heat output for the Montecito
Estate is achieved by burning with the door
closed and the combustion air opened and
pulled out. Through this method, the Montecito
Estate can produce up to 80,000 BTU of heat
per hour.
However, it will be necessary to reload with wood
every one or two hours. This is the least efficient
method of burning the Montecito Estate .
Use caution when firing with the combustion
air control wide open. Only burn cord wood in
this manner. Small dry pieces of softwood and
construction scraps will burn very intensely us-
ing this method and may damage the firebox.
Medium Combustion
This is the recommended mode of operating
the Montecito Estate and should be the one
normally used since it will deposit the least
amount of creosote on the glass and in the
chimney. The combustion air control must be
3/4 closed. The precise setting will depend on
many factors, including chimney length and the
moisture content of the wood.
For instance, a long chimney will necessitate
closing the damper more. To obtain the proper
combustion, close the damper completely, then
open it about 1/4” to 1/2”. Three medium size
pieces of cord wood-burning on a bed of hot
coals will generate an approximate heat output
will of 35,000 BTU per hour and the loading time
will be about every 3-4 hours. Softwoods may
be burned using this method but the combustion
time will be substantially reduced.

COMBUSTION CONTROLS
Primary Air & Air Boost Controls
There is no flue damper in the Montecito Es-
tate™. As is common with air tight appliance,
the combustion air control sets the flow of air
entering the firebox. This allows for a more
precise control of the fire. The combustion air
control is located below the door on the left side.
The main source of air (primary air) entering
the firebox can be diminished by moving the
air combustion control from left to right. The
primary air is fully opened when the air control
is completely moved to the left. This air com-
bustion control should be in the closed position
when the fireplace is not in operation. This will
minimize air leakage up the chimney.
