NOTE: Filling installation with water when boiler is in use, especially if it is
very hot is strictly forbidden, as boiler’s damage or fracture may be caused.
Once heating season is over do not get rid of water from heating installation and
boiler. When required, water may be let of through blowdown connection to a drain
once it is cooled down.
7.2. FIRING UP A BOILER
Firing up a fuel in boiler should be started when checked if heating installation is filled
with water, and water is not frozen. It should also be checked, if water is not
leaking through thread fittings on boiler. Do not forget to heat the chimney prior to the
firs startup.
Before the fire up, smoke throttle in the smoke conduit should be fully
opened, as well as ash box and furnace door, likewise the fuel charge door
which should be fully closed. The operation should be performer slowly, using
crimpled pieces of paper and wood. Then thin layer of coal is applied. Once the
batch of coal is glowing, ash box and furnace door should be closed. Open
fuel load door and fill the combustion chamber with fuel, up to the lower edge
of the load door. Then, close the load door and position the smoke throttle in
the smoke conduit. Also, in order to obtain the required temperature and heat
capacity close air dosing flap placed on the ash box door, using the string and an
air draft regulator.
During fire up process the boiler should be monitored until it gets feeding
water temperature of 45°C. It is important, as v arying fuel quality may cause
the boiler to go out.
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.
Person operating the boiler should know that some of boiler’s areas are
hot, therefore protective gloves should be worn! The same applies to
protective goggles.
