Lighting the Fire
Procedure
Switch air slider to the
heating-up position.
Pile up any remaining ash
and unburned charcoal
into the centre of the
combustion chamber.
Place the logs in the

CAUTION!
Please ensure that the logs are inserted
with sufficient distance (at least 5 cm)
from the furnace window.
The air slider must not be left in the
heating-up position once the warming up
phase is complete.
9. Heating at Low Thermal Output
(during Transitional Seasons)
Fig. 6
You can vary the thermal output of your PATNA by
adjusting the quantity of fuel used.
NOTE!
Do not attempt to slow down the
combustion by reducing the air supply.
When heating with wood, this can result in
an incomplete burning process and pose
the risk of an explosive like combustion of
the accumulated wood gases (deflagration).
During the transition seasons (spring/
autumn), outdoor temperatures in excess
of 16° can cause disruptions to the airflow
in the chimney. If at this temperature a
draught cannot be created by burning a
piece of paper or a small piece of wood (a
pilot fire), no fire should be lit.
