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 appli-
ances 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
PX42 Gas Valve
Leak sprays and liquids clog the reference hole P1. Ref. (Fig. 40) 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).
Gas Valve 848
Leak sprays and liquids clog the reference hole PR Ref. (Fig. 41) 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).
The storage tank unit, if present, must also be installed in an environment in which the temperature cannot fall below 0°C.
"Anti-Legionella" heat treatment of the Immergas storage tank (only if paired with a storage tank unit and function enabled
when the system is provided with temperature control).
During this phase, the temperature of the water inside the tank exceeds 60°C with the subsequent risk of burns.
Keep this domestic hot water treatment under control (and inform the users) to prevent unforeseeable damage to people, ani-
mals, things.
If required install a thermostatic valve on the domestic hot water outlet to prevent scalding.
