When loading coal, use grid bars (see fig. 5.3.), open by pulling up the air valve for coal and peat
turf to clean up ash and slag.
Fig. 5.3.
Grid bars for coal and peat turf firing.
Load lump coal, larger coal like a computer mouse cut into smaller pieces. Do not load any other
fuel; only at the top of coal load about 2 kg of dry chipped firewood logs.
By
turning
a
regulating screw (see
figure 5.4. A) open an
air control valve for 3-5
cm. Kindle the top of
the load (fig. 5.4. B),
slightly close the door
leaving a gap of 1-3
cm. When fuel burns
up, close the door and
unhook a ring with a
lifting cable. Liquid
fluid used for firing of
fireplaces and ovens
can be used for firing
of the boiler however it
can not be used during
combustion.
