5.2 Positioning possibilities
Boiler positioning in the living space (including corridors) is prohibited!
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 ČSN 06 1008.

1. Positioning on the floor made of incombustible material (Fig. No.6)
- The boiler can be installed on a fireproof thermally insulating 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 the combustible materials
- when installing and operating the boiler it is necessary to keep a safety distance of 200 mm from the
