The boiler must be placed on a flameproof pad that exceeds the boiler outline by 2 cm. if the
boiler is located in the basement, it is recommended that it is placed on a base of at least 5 cm thick.

location for the boiler i.e:
20 cm - from any flammable materials
40 cm - from any flammable materials of C3 flammability
40 cm - from any flammable materials of unknown flammability
