3.2.5 Accelerated Combustion
The maximum heat output for the LE LAVAL fireplace is
achieved by burning with the door closed and the combustion
air opened. However, it will be necessary to reload with wood
every hour.
This is the least efficient method of burning
the LE LAVAL fireplace.
Use caution when burning with
the combustion air control wide open. Only burn cordwood
in this manner. Small dry pieces of softwood and
construction scraps will burn very intensely using this method
and may damage the firebox.
3.2.6 Medium Combustion
This is the recommended mode of operating
the LE LAVAL fireplace 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 ½". Three medium size
pieces of cordwood burning on a bed of hot coals will burn about 1-2 hours. Softwoods may be
burned using this method but the combustion time will be substantially reduced.
FOR MAXIMUM HEAT OUTPUT, WE STRONGLY RECOMMEND THE
INSTALLATION OF THE OPTIONAL HOT AIR DUCTING SYSTEM.
3.2.7 Building a Fire
A) To start a fire, place several crumpled up balls of newspaper in the firebox. Place small dry
pieces of kindling on top of the paper, criss-crossing the kindling so that there are air spaces
in between. The kindling should be placed at the center of the firebox so as to allow for
sufficient air circulation.
B) Open the dampers and light the newspaper. Leave the doors partially opened (1 to 2 inches)
to facilitate the start-up.
C)
Once kindling fire is well established, cordwood can be added. Close the doors and leave the
combustion air control open in accelerated combustion position
D)
When the fire burns well set the primary control to the desired burn level.
The unit will burn best with 2-3 pieces of cordwood spaced 1 to 2 inches apart and allowing
air to get under the fuel. Criss-crossing or arranging the fuel so that air can get underneath
will help the fire to get started easily. The unit should be operated with the air control fully
open long enough to get the cordwood well ignited.
WARNING: LE LAVAL was designed to allow a spectacular view of the fire. LE LAVAL
fireplace should never be filled in excess (five big logs and more). Excessive fire could
damage the fireplace’s hearth and refractory brick and void the warranty.
