9.2 Positioning possibilities
Boiler can be installed in the 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.
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.
Boiler positioning with regard to the fire regulations:
1. Positioning on the floor made of combustible material
−
Install the boiler on a incombustible thermally insulating pad exceeding the boiler ground-plan by
15 mm on all sides.
−
If the boiler is installed in a cellar we recommend to install it on a retaining wall at least 50 mm high.
2. A safe distance from the 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.
3. Positioning of a boiler designated for propane combustion must comply with Č SN 38 6462.
