risk of damage due to corrosion caused by unsuitable combustion air and environment.
Spray, solvents, chlorine-based detergents, paints, glue, ammonium compounds, powders and similar cause product and flue
duct corrosion.
Check that combustion air power supply is free from chlorine, sulphur, powders, etc.
Make sure that no chemical substances are stored in the place of installation.
If you want to install the product in beauty salons, paint workshops, carpenter's shop, cleaning companies or similar, choose a
separate installation area that ensures combustion air supply that is free from chemical substances.
Make sure the combustion air is not fed through chimneys that were previously used with boilers or other central heating
appliances powered by liquid or solid fuels. In fact, these may cause an accumulation of soot in the chimney.
risk of material damage after using sprays and liquids to search for leaks
Leak sprays and liquids clog the reference hole PR Ref. (Fig. 43) of the gas valve, damaging it irreparably.
During installation and maintenance, do not use spray or liquids in the upper area of the gas valve (side referring to the electric
connections).
filling the condensate drain trap
When the appliance is switched on for the first time, combustion products come out of the
condensate drain. after a few minutes of operation, check that combustion flue gases are no
longer coming out of the condensate drain; this means that the drain trap has filled to a correct
condensate height that the flue gases cannot pass through.
