Positioning possibilities
VIADRUS G 90 boiler can be installed in basic environment AA5/AB5 according to
Č
SN 33 2000-3. It
conforms to the use in the rooms detached from the housing rooms themselves.
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
Č
SN 06 1008
When positioning the boiler it is necessary to keep „VIADRUS G 90 boiler installation manual (delivered in a
decomposed state)
Boiler positioning with regard to the fire regulations:
1. Installation on the floor made of a flammable material
−
Put the boiler on a fireproof pad or a bedding approx. 50 mm high, while both the pad and the
bedding exceed the boiler ground plan on all sides by 15 mm.
2. A safe distance from the 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 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.

polyethylene, PVC,…
Boiler position with regard to the necessary handling space:
−
in front of the boiler there must be left a handling space minimum 1000 mm
−
minimum distances between the rear part of boiler (the place of all connections) and the wall 600 mm
−
on the side of atmospheric burner there must be left a free space min. 800 mm
Warning:
The boiler room, in which the boiler VIADRUS G 90 is installed, must be equipped with the safety
elements in compliance with
Č
SN 07 0703 – Boiler room with gas fuel –operated equipments.
