2. Positioning and Installation of the PYROMAX Wood Gasication Boiler
The installation of the PYROMAX wood gasication boiler requires the expert knowledge of an authorized technician. It is
strongly recommended to place the boiler on a stable concrete base with a height of 50-100 mm. The boiler room must be
adequately protected from freezing and should have sucient ventilation. The arrangement of the boiler should ensure both
chimney connection and accessibility for maintenance, cleaning, and servicing operations.
Connecting the boiler to the central heating system requires the use of one or more storage tanks, depending on the boiler’s
power. It is recommended to connect a minimum water quantity of 55 liters per kW of rated power. For example, for a 40 kW
boiler, a minimum volume of 2200 liters is recommended. It is essential to note that the boiler should never be used without a
storage tank.
The connection between the boiler and the storage tank must be made exclusively through a three-way return valve, which
maintains the return temperature at a value above 60°C. This ensures the proper operation of the system and contributes to
the eciency of the heating process.
