9.4. Important recommendations for long-lasting
and correct operation of the boiler.
- C arry out periodic maintenance of boiler following
EN
the prescriptions in Section 9.3.
- T he allowed moisture content of the fuel used must
not exceed 15% ÷ 20%.
- G as emission in the combustion chamber may result
in the formation of tar and condensate (acids).
Therefore, a mixing valve must be installed and it
must be adjusted so that the minimum temperature
of the water returning in the boiler is 65° С. This
extends the life span of the boiler and its warranty.
The operating temperature of the water in the
boiler must be within the 65 ÷ 85°С range.
- I t is not recommended to operate the boiler for a
long period of time at an output lower than 50%.
- W hen using circulation pump, boiler operation must
be controlled via a separate thermostat in order
to ensure the prescribed rated temperature of the
return water.
- T he eco-friendly operation of the boiler is realized at
rated output.
- I t is recommended to install a storage/buffer tank
and pump type group with thermostatic mixing
valve to the boiler. The capacity of the storage tank
is 55 L of water per 1 kW installed boiler power.
- M aintenance and operation training for the boiler is
conducted by an authorized installer
Failure to observe the installation and
*
operating requirements described in the
manual and the service booklet voids the
warranty.
