company.
An efficient ventilation and flue system is required for
a correct and safe boiler (heating system) operation.
The maintenance and the operation of the flue ducts
are covered by the following regulations::
of Laws No. 81 as amended [Dz. U. Nr 81])
No. 80/06 [Dz.U. 80/06]).

9. Notes, guidelines and tips
Before burner start-up check water level in the
heating system. Fuel storage hopper must be filled
with fuel to a required level to guarantee a reliable
boiler operation.
CAUTION!
Using the fuel with different specifications may affect
device operation and cause damage. The fuel with foreign
material (e.g. stones) is treated as unsuitable for pellet
burners. The manufacturer is not liable for any damage
of using fuel with different specifications.
Use safety gloves as a protection against burns and follow
safe operation guidelines to ensure safe maintenance.
The heat exchanging surfaces are fouled during operation resulting
in an increase in temperature at the flue gas outlet and reduced
efficiency.
CAUTION!
The device has to be installed and commissioned by
a company authorized by the manufacturer, otherwise
it may invalidate the warranty.
Do not open the doors and covers with boiler in operation (burn
hazard). Do not open the doors during fuel ignition (explosion hazard).
Do not use starters and flammable materials to light a fire. Do not
store flammable materials near the boiler or the burner.
Keep the minimum return temperature (60°C) to ensure correct boiler
operation - risk of flue gas water condensation. Some condensate
may occur during start-up (heating).
After the heating season, thoroughly clean the boiler and the flue ducts.
Keep the boiler room clean and dry.
