4.10 Firing Tips
It is important to use wood of an appropriate size (length and diameter) and to stack it properly so that
there are no “holes” and “hanging pieces” in the wood stack, which must then be regularly stirred with
the poker to form it into a compact mass. The diameter of the wood ideally should not exceed 4-6
inches (10-12 cm) as “holes” would then form more easily in the wood layer, creating a risk of re-
duced heating output. Thick pieces of wood ideally should be split to a diameter of 4-6 inches (10-12
cm).

4.11 Cleaning and Maintenance
4.11.1 Ash Removal
The boiler must be cleaned regularly. Lack of cleaning can result in loss of boiler efficiency, malfunc-
tioning and reduced boiler life.
Most ash produced during boiler operation will be drawn down into the gasification chamber where it
can be removed. Ash should be cleaned out of the gasification chamber, from both the combustion
tunnel and the refractory floor, through the ash door as needed, typically every 3-5 days.
Clean the firebox once or twice a month. Ash remaining in the firebox can be worked from the sides
of the firebox to the slot at the center of the refractory where it can fall down to the lower gasification
chamber with the tool provided - use care not to damage the refractory slot. Do not allow a deep build
up (more than 2” (51 mm)) of ash on the surface of the refractory.
For ash removal, open the insulating door and the ash door, place your ash pan on the floor in front of
the ash door and pull the ash in this area into the pan using the ash removal tool. Be sure to remove
duced by the boiler will depend on the type of fuel used.

WARNING
Before performing any cleaning or maintenance on the boiler, allow boiler to completely
burn through all fuel and to normally cool down and shut off.
NOTE
Turn off power to the boiler before performing any cleaning or maintenance.
WARNING
Ashes removed from the boiler should be placed in a metal container with a tightly fitting lid
The closed container of ashes should be placed on a non-combustible floor or on the ground,
well away from all combustible materials, pending final disposal. If the ashes are disposed of by
burial in soil or otherwise locally dispersed, they should be retained in the closed container until
all cinders have thoroughly cooled. Other waste should not be placed in this container.
