Positioning possibilities
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 incombustible material
−
The boiler can be installed on a fireproof and thermally instulating bottom which exceeds the boiler
platform by 20 mm on the sides.
−
If the boiler is installed in a cellar, we recommend to install it on a minimum 50 mm high retaining wall
(bedding). The boiler must be installed straight, possible unevenness of the retaining wall can be
eliminated by means of the engine bed regulation screw.
2. Safety 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.

Examples of building materials and products included in the reaction to fire
(Extract from EN 13 501-1 + A1)
A1 – incombustible
Granite, sandstone, concrete, bricks, ceramic tiles, mortars, fireproof plasters, …
A2 – combustible with difficulty acumin, izumin, heraklit, lignos, boards and basalt felt, fibreglass boards,...
B – hardly combustible
Beech and oak wood, hobrex boards, plywood, werzalit, umakart, sirkolit,...
C (D) – medium combustible
Pinewood, larch, whitewood, chipboard and cork boards, rubber flooring,...
E (F) – easily combustible
Asphaltboard, fibreboards, cellulose materials, polyurethane, polystyrene,
polyethylene, PVC,…
Boiler positioning with regard to the necessary handling space:
•
Basic environment AA5 / AB5 according to
Č
SN 33 2000-3
•
In front of the boiler there must be left a minimum handling area of 1000 mm
•
The minimum distance between the rear part of boiler and wall 400 mm.
•
On the side of fuel reservoir there must be left min. space 800 mm in case of screw feed removal
•
Minimum distance from the left side wall 100 mm
•
Above the boiler in min. 450 mm to clean the convection part of boiler exchanger.
Boiler positioning with regard to electricity network:
•
The boiler must be placed so that the plug in socket (230V/50Hz) is always accessible.
