Placement options
The boiler is equipped with the movable mains supply and plug. According to EN 60 335–1 ed. 2
Art. 7.12.4, the boiler must be positioned in such a way that the plug is accessible.
The boiler positioning in the living space (including corridors) is prohibited!
When installing and using the boiler, all requirements of CSN 06 1008 must be complied with.
The boiler positioning with regard to fire regulations:
1. Placement on the floor made of incombustible material
−
place the boiler on a fireproof and heat-insulating base exceeding the boiler dimensions on the sides by 20
mm;
−
if the boiler is installed in a cellar, we recommend to install it on a substructure at least 50 mm high. The
boiler must be installed straight, any possible inequalities of the substructure are eliminated by means of
adjustable foot (see Fig. 13)
2. Safe distance from flammable materials:
−
when installing and operating the boiler it is necessary to keep the safe distance of 200 mm from flammable
materials with combustibility grade A1, A2, B and C (D);
−
for easily flammable materials with combustibility grade E (F), which burn quickly and by themselves also
after the ignition source removal (e.g. paper, cardboard, asphalt and tar boards, wood and fibreboards,
plastics, flooring materials), the safe distance is doubled, that is 400 mm;
−
the safe distance is to be doubled also when the fire reaction class is not proven.
