3. General remarks
Since boiler design is constantly improved, inessential deviations from this
manual can occur.
During boiler installation, observe all building standards and fire protection
requirements.
Armrest is not a part of boiler body, so don’t use it to lift or move the
boiler.
Boiler installation, adjustment and operator training can be entrusted only
to the certified firm which has specialists able to carry out installation works
or manufacturer-authorized representative. Installed and connected boiler
has to be checked by fire safety personnel.
Boiler can be installed into the system which maintains no less than 60
ºC return water temperature. In the case of failure to observe this
requirement, condensate-related corrosion will significantly shorten the
boiler body service life.
It is strictly forbidden to start the boiler without having filled it with
technical water.
After starting the boiler for the first time, when its body heats up and paint
finally cures, volatile substances with unpleasant smell are released, so
adequate ventilation of the premises is necessary.
Use the fuel which has no more than 25 per cent of moisture. With higher
fuel moisture, boiler power decreases and fuel consumption increases.
In the case of too strong chimney draft, or if using sawdust, shavings,
chaff or other bulk materials, during fuel loading or after burn out and shaking
the remaining fuel, sparks can escape from the chimney.
It is strictly forbidden to use mentioned types of fuel if roofing or building
constructions are made of easily combustible materials, or there are building
materials or fuel stored at a distance less than 20 m away from the chimney!
Boiler operates at optimum when it reaches power close to nominal.
In the cases when less heat is needed than the boiler’s nominal
power, don’t load combustion chamber at full for there was no constant
smoldering of the loaded fuel (resins can start accumulating in the boiler).
It is advisable to load only one third of the chamber.
It is strictly forbidden to pour water over the burning fuel in the
combustion chamber. This can irreversibly damage the boiler.
