7. BOILER ASSEMBLY
A solid fuel boiler may only be installed by a company with a valid authorization to install it or by a person authorized by us. The
list is available at opop.cz or you can request it at the telephone number 571 675 589. The project must be prepared according to
the valid regulations.
Boiler placement
The boiler must be installed in a separate boiler room, specially designed for
heating. The boiler room must have sufficient space for installation and
maintenance of the boiler. Sufficient circulation of fresh air for combustion must
be ensured, the design of the chimney must ensure adequate draft for the type of
boiler and must be in accordance with the installation criteria set forth in this
manual and in the binding regulations. Never install the boiler in open spaces or
balconies in areas occupied by people such as kitchen, living room, bathroom,
bedroom, in areas where explosive and flammable materials are present.
Install the boiler on a concrete base made of flame retardant material or on a fireproof substrate.
A minimum of free space should be around the boiler. During installation and during operation of the boiler, a safe distance of
200 mm from the flammable masses of the degree of flammability B, C1 and C2 (according to ČSN 06 1008) must be observed.
For lightly flammable substances of degree of flammability C3, which quickly burns and burns themselves after removal of the
ignition source (eg paperboard, cardboard, bitumen and tarpaperboard, wood and fiberboard, plastics, floor coverings), the safety
distance doubles, to 400 mm.
The safe distance must also be doubled if the degree of flammability of the building material is not proven.
Installation of heating system pipes
In the rear part of the boiler is welded water inlet and outlet with diameter G1 1/4 "These pipes can also be fitted with old type
flanges if you change our old boiler to a new one and you do not want to change the pipes to connect to the boiler. Then the boiler
fits its dimensions to the heating circuit to which our older type of H4v or H4eko boiler has been connected. Please inform us or
your local retailer about the possibility of buying these flanges if you change the boiler from one of the older ones.
The heating system must be designed according to ČSN 06 0310: 2006 (Central heating, design and installation), ČSN 06 0830:
2006 (Safety devices for central heating and domestic hot water), ČSN 07 7401 (Water and steam for thermal energy devices with
working steam pressure up to 8 MPa, EN 303-5 (Central heating boilers - Part 5: Solid fuel boiler with manual or automatic fuel
supply, rated at maximum 300 kW.
The boiler must be installed in combination with the buffer tank.
Installation of the drain valve
At the bottom of the boiler, a ½ "nozzle is welded to the boiler, into which the drain valve is screwed. After filling the water into
the system, it is necessary to close the valve!
Connection to the chimney
The boiler may only be installed to the chimney according to ČSN 73 4201: 2002. The connection of the hot water boiler must only
be carried out with the approval of the chimney. The boiler must be connected to a separate chimney flue which has sufficient
draft for virtually all possible operating conditions.
The draft of the chimney is always lower at the time of increasing humidity, mist and the heated head of the chimney
on which the hot sun has been lit for a long time.
