THERMOROSSI DECLINES ALL RESPONSIBILITY FOR THE CORRECT FUNCTIONING AND DURATION OF THE
APPLIANCE IF ALL OF THE ABOVE GUIDELINES ARE NOT OBSERVED. NO TECHNICAL SERVICING BY OR ON
BEHALF OF THERMOROSSI, CAUSED BY THE NON-OBSERVANCE OF THESE RECOMMENDATIONS, WILL BE
COVERED BY WARRANTY.
Before installing your central heating cooker we recommend that your flue outlet has a suitable draught.
We recommend connecting the plant circulating pump to the central heating cooker’s control panel.
We recommend installing nonreturn valves to prevent natural circulation phenomena between the central heating cooker and the
plant (see drawing par. 4.5 - 4.6 - 4.7 - 4.8 ). The presence of open boilers causes natural circulation on the water surface with
subsequent oxygenation of the water. The presence of natural circulation produces condensation and can consequently cause
corrosion to parts of the central heating cooker.
We recommend you earth the central heating cooker and check the efficiency of the earthing of the electrical system to which the
central heating cooker is connected.
