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 combustion control should be in the closed position when the fireplace is not in operation. This will minimize air leakage up the chimney.

The combustion air control should be opened before opening the doors to minimize the possibility 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 using 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.
