Č
SN 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

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.
