2.3 Positioning possibilities
Boiler positioning in the living space (including corridors) is prohibited!
A continuous air supply for burning and eventual ventilation must be ensured for the room where the
boiler is installed.
The installation of the boiler must comply with all requirements of ČSN 06 1008.
Boiler positioning with regard to the fire regulations:
1. The boiler can be installed on a fire-proof floor (Fig. no. 5):
Place the boiler on fire-proof base exceeding the boiler platform by 20 mm on 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 minimum 50 mm
hight.
Install the boiler in the middle of the retaining wall.

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.
