3 Description
3.1 Boiler structure
The main part of the boiler is the sectional boiler drum made from grey cast iron according to EN 1561 grade 150.
Pressurized parts of the boiler complies with requirements for stiffness according to EN 303-5.
The boiler drum is assembled from sections by means of pressed boiler insertions and is fixed by anchor bolts. The sections create the heating
and ash space, the water space and the convection part. The heating water input and output are situated in the rear part of the boiler.
The rear section of the boiler has in its upper part a chimney pot and a heating water flange, in its bottom part has a return water flange with a
mouthpiece for a filling and draining cock. The cleaning and ash doors with an inbuilt burner are fixed to the front section.
The whole boiler drum is isolated by healthy mineral insulation, which decreases losses caused by heat transmission to the surroundings. The
steel cladding is painted by quality comaxite paint coat.
A pellet burner of PellasX is mounted in the ash door. In the version VIADRUS A0C-S20P it is a burner PellasX Hybrid mini, and in the version
VIADRUS A0C-S28P it is a burner PellasX Hybrid 35. These burners are equipped with a fan.
On the right (on the left) from the boiler it is placed a steel-sheet pellet reservoir with a capacity of 300 l. The reservoir is connected with the
burner by means of a feeder and a connecting hose.
An electric cabinet, in which the control unit and a display are situated, is mounted on the upper part of the cladding.
The unit is supplied in two versions. The S.Control with button control or the S.Control Touch with touch display.

4.2 Possibility of placement
During boiler mounting and operation it is necessary to observe all requirements of ČSN 06 1008.
It is prohibited to place the boiler in a residential premise (including corridors)!
Placement of the boiler in the view of fire regulations:
1. Placement on the floor from inflammable material
−Install the boiler on an inflammable, heat-insulated basement exceeding the ground-plan of the boiler with the reservoir on sides by 20
mm.
−If the boiler is placed in a cellar, we recommend to install it on a supporting brickwork with the high at least 50 mm. The boiler has to
stay horizontally, possible unlevelnesses of the supporting brickwork are to be eliminated by means of a regulating screw of the motor
seat.
2. Safety distance from flammable materials
−During installation and at operation of the boiler it is necessary to observe a safety distance 200 mm from flammable materials with the
combustibility grade 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.
Tab. №. 4 Grade of reaction to fire

Placement of fuel:
•For correct combustion in the boiler it is necessary to use dry fuel. The producer recommends to stock fuel in cellar premises or at
least under a penthouse,
•The producer recommends to observe distance between the boiler and fuel at least 1 000 mm, or place fuel to the room than the boiler.
It is necessary to provide constant supply of air for combustion and possible ventilation into the room where the boiler is installed (air
consumption of the boiler VIADRUS A0C-S20P is about 75 m
3
