In the next step some pieces of crumpled paper and wood are to be placed on the
furnace.
Fire up the lighting material introduced into the furnace space. Once it is burning
– use an opening of fuel load - cleaning door in order to deliver a thin layer of
coal. Once coal is burning, use the same opening for introducing a slightly thicker
layer of coal again, once it is glowing, the furnace chamber may be filled with fuel
(prior to that double door should be closed). In the next step the position of air
intake dosage flap should be determined.
This position is established by means of regulation screw or string and air draught
regulator. This way, heating capacity and temperature required may be obtained.
Temperature may be controlled by thermometer.
In case of fire in boiler went out during fire up operation a furnace must be
cleaned, boiler’s channel should be ventilated and fire up should start again. During
the process a smoking or sweating of boiler may occur. Once boiler and chimney
duct get hot, those adverse phenomena should go away.
During normal exploitation of boiler in the “traditional combustion” mode burning
process is based on periodic refueling. Single load of basic fuel is sufficient for 5
hours of boiler operation at rated power. With lower capacity the period of slow
burning (time gap between refueling) may be elongated to several hours.

CLEANING THE BOILER
In order to use fuel in the safe manner, and to get declared boiler’s power
and heat efficiency, keeping adequate cleanliness of combustion chamber and
convection channels is indispensable.
Convection channels, where ashes are tend to gather should be cleaned
systematically, every 3÷7 days. For this purpose the boiler is provided with tools.
Convection channels cleaning is performed using cleaning wholes (pos. 18) placed in
the upper part of boiler and front charge-cleaning door (pos.6). Once cleaning
operation is accomplished, whose holes should be closed. Forming dust should be
removed using door of side wall washout opening (pos. 26). Failure to follow these
recommendations may result in high heat losses, and render difficult gases circulation
in consequence make smoke coming out of boiler. In case of using a fuel prone to
