TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
9.4. Important recommendations for long-lasting
and correct operation of the boiler.
- Carry out periodic maintenance of boiler following
the prescriptions in Section 9.3.
- The allowed moisture content of the fuel used must
not exceed 15% ÷ 20%.
- Gas 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.
- It is not recommended to operate the boiler for a
long period of time at an output lower than 50%.
- When using circulation pump, boiler operation must
be controlled via a separate thermostat in order
to ensure the prescribed rated temperature of the
return water.
- The eco-friendly operation of the boiler is realized at
rated output.
- It 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.
- Maintenance 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.
10. WARRANTY TERMS
The warranty terms are described in the Service
booklet included in the supply.
