The boiler should be placed on a heat insulating non-flammable base, which on each side of the boiler should
be larger than the base of the boiler by 2 cm. If the boiler is located in a cellar, it is recommended that it is
placed on a foundation of at least 5 cm. The strength of the foundation as well as the fire protection conditions
are key guidelines when placing the boiler in the right location, these include:
●
20 cm safety distance from flammable materials,
●
40 cm for flammable materials of flammability grade C3,
●
40 cm if flammability is not known.
