Possibilities of placement
Boiler can be installed in the basic environment AA5/AB5 according to ČSN 33 2000-1 ed. 2. 2. It must not be installed in zones 0,1,2
according
to
ČSN 33 2000-7-701 ed. 2.
The boiler is equipped with a flexib
le mains connection and a fork. According to ČSN EN 60 335–1 ed. 2, art. 7.12.4, the boiler has to
be placed so that the fork is accessible.
Boiler positioning with regard of fire-fighting regulations:
1.
Positioning on the floor made of combustible material
Install the boiler on a incombustible thermally insulating pad exceeding the boiler ground-plan by15 mm on all sides
If the boiler is installed in a cellar we recommend installing it on a bedding at least 50 mm high.
2.
Safety distance from flammable materials:
when installing and operating the boiler, it is necessary to keep a safety distance of 200 mm from the materials of combustibility
grade of A1, A2, B
and C (D);
for lightly combustible materials with the combustibility grade E (F), which quickly burn and burn themselves even after removal of
the ignition source (for example, paper, paste-board, cardboard, asphalt- and tarboard, wood and fiberboards, plastics, floor cloths)
the safety distance is doubled, it means to 400 mm;
the safety distance is to be also doubled in case when the grade of reaction to fire is not proven.

Positioning of a boiler with regard to the necessary handling space:
in front of boiler there the handling space at least 1000 mm must be left
minimum distance between the rear part of boiler and the wall is 400 mm
at least from one side part, the space for accessing the rear part of boiler (minimum 600 mm) must be kept
minimum distance from the side wall is 200 mm, in case of delivery together with heater OV 100L it can be positioned alongside the
boiler from the left and right hand side (the boiler cladding at this way of installation can only be dismantled after the heater cladding has
been dismantled)

Positioning of boilers in a boiler room
Air supply requirements:
The boiler can only be installed in a room with sufficient air supply according to EN 1775.
Positioning of a boiler equipped with forced flue gases exhaust
The conditions for gas fuels appliances combustion products venting o
utfall on the exterior wall (façade) are prescribed by
TPG Technical
rules - G 800 01 equipment for gas combustion.
