5.2.2 The Top Down Method
The down fire method has two advantages over the traditional method: first, the fire does not
collapse on itself, and it is not necessary to add wood gradually since the combustion chamber
is full before the fire is lit. This method is the opposite of the conventional method and only
works properly if well-seasoned wood is used.
Place three or four small, split, dry logs in the firebox. Arrange the kindling wood on the logs
in two layers at right angles and place a dozen finely split kindling on the second row. Use four
or five sheets of paper tied together and put them on top and around the kindling. Open the air
intake control completely, ignite the paper and close the door.
5.2.3 Two Parallel Logs Method
Two spit logs are placed in the firebox with a few sheets of twisted newspapers in between the
logs. Fine kindling is added across the two logs and some larger kindling across those, log cabin
style. Newspaper is lit.

Combustion Cycles

Wood burns best in cycles. A cycle starts when a new load of wood is ignited by hot coals and
ends when that load has been consumed down to a bed of charcoal about the same size as it
was when the wood was loaded.
Trying to produce a steady heat output by placing a single log on the fire at regular intervals
is not recommended. Always place at least three, and preferably more pieces on the fire at a
time so that the heat radiated from one piece helps to ignite the pieces next to it. Each load of
wood should provide several hours of heating. The size of each load may vary depending on the
amount of heat required.

Rekindling a Fire

When the temperature of the room is lower and all that remains is embers, it is time to reload.
Remove excess ash from the front of the firebox and bring the ashes forward. Place a new load
of wood on, and at the back of the embers. Open the air control completely and close the door.
Raking the coals is useful for two reasons. First, it brings them near where most of the combustion
air enters the firebox. This will ignite the new load quickly. Secondly, the charcoal will not be
smothered by the new load of wood. When the embers are simply spread inside the combustion
chamber, the new load smoulder for a long time before igniting. Close the air control only when
the firebox is full of bright turbulent flames, the wood is charred, and its edges are glowing.
The heater should not be left unattended during ignition and the fire should not burn at full
intensity for more than a few minutes.
