OSV can rotate round the vertical axis by 90° to the left or to the right, according to the needed direction of
combustion products outfall.
Wiring is done through the interconnection with boiler terminal board. Individual conductors are signed by
numbers that correspond to numbers on boiler terminal board:
Terminal no. 8 – blue conductor
Terminal no. 9 – black conductor
Terminal no. 10 – brawn conductor
Terminal PE – yellow &.green conductor
In the boiler terminal board there must be removed the interconnection between terminals no. 9 and 10. The
conductor from ventilator at point it enters the shell and the panel must be protected by MEOS clip against its
rapture.
Following principles must be observed when assembling the smoke-flue:
- Every joint of smoke-flue must be secured by at least one sheet-metal screw in order to prevent it from
disjunction
- The length of individual parts insertion is 50 mm
- The neck of ventilator and draught diverter must be secured by at least two sheet-metal screws in against
each other position at point of joint
- The combustion products must be vented either vertically or horizontally but never downwards (there is
only allowed the max. gradient 3° downwards for condensate effluent, but no condensate should be
produced with regard to a high ventilator output).
- Smoke-flue piping outfall protruding from the wall must be equipped with an end piece (see fig. no. 15,16)
- The whole smoke-flue assembly is limited by the used elements (see tab. no. 9)
When assembling the smoke-flue for:
- 8 – 34 kW output the flow resistances summation must not exceed the value of 10
- 41 – 49 kW output the flow resistances summation must not exceed the value of 7 and no 90° elbow but
only a bend is to be used in smoke-flue.

Smoke-flue calculation example for boiler of 26,5 kW output:
We use: 1 x elbow (K90), 1 x bend (O90), 2m piping (2 x T80), 1 m pipe with an end piece
Resistances summation = 3 + 2 + 2 x 1 + 2 = 9 is satisfactory

Regulations and directions
Boiler can be installed by a company holding a valid license to install and maintain the gas
appliances. A project according to the valid regulations must be prepared for installation.
The heating system must be filled with water, that meets the
Č
SN 07 7401 requirements, especially
its harness must not exceed the required parameters.
