Choice of the location
Before mounting the boiler, decide on the ideal position for mounting,
bearing in mind any Directives and the dimensions of the appliance.
Caution
Install the boiler in a frost-free location.
Caution
Install the boiler on a solid, stable structure able to bear its weight.
Caution
Do not stock chloride or fluoride compounds close to the boiler.
They are particularly corrosive and may contaminate the
combustion air. Chloride and fluoride compounds are present in
aerosol sprays, paints, solvents, cleaning products, washing
products, detergents, glues, snow clearing salts.
Caution
Do not store, even temporarily, explosive or easily combustible
materials in the boiler room or near the boiler.
Caution
Use plugs for the intake of air and discharge of combustion gases
observing the prevailing regulations and directives.
