INSTALLATION
The maximum pressure during boiler heating is adjusted via the control panel.
After all the calibration operations have been completed, close and seal the pressure outlet used. Calibration of slow ignition
is electronic and adjustable (for optimisation and gas change) via the control panel.
The boilers leave the factory calibrated and set up to operate with G20 (natural gas) or G30/G31 (LPG).
