5.2 Positioning possibilities
Boiler can be installed in basic environment AA5/AB5 according to Č SN 33 2000-1 ed. 2. It must not
be installed in zones 0,1,2 according to Č SN 33 2000-7-701 ed. 2.
The boiler is equipped with a movable mains supply and a plug. The boiler must be according to
EN 60 335 – 1 ed. 2 Art. 7.12.4 positioned in a way making sure that the plug is accessible.
The installation of the boiler must comply with all requirements of
Č
SN 06 1008.
Boilers positioning with regard to the fire regulations:
1. Positioning on the floor made of incombustible material
−
Install boiler on fireproof thermally bottom exceeding the boiler platform by 20 mm on the sides and only
up to the boiler drum depth.
−
If the boiler is positioned in a cellar we recommend to install it on a retaining wall (bedding) minimum
50 mm high
2. A safe distance from combustible materials
−
when installing and operating the boiler it is necessary to keep a safety distance of 200 mm from the
materials of combustibility grade A1, A2, B and C (D);
−
for easily combustible materials of combustibility grade E (F), which quickly burn and burn themselves
even after removal of ignition source (such as paper, cardboard, asphalt and tar paper, wood and wood-
fiber boards, plastics, floor coverings) the safe distance has to be doubled, i.e. to 400 mm;
−
safe distance should be doubled as bulb where the grade of reaction to fire has not been proved.
