Basic connection scheme of boiler Ladan into the central heating system
The boiler should be connected into the central heating system of which the capacity is
appropriate to the boiler output.
The boiler must be connected to the flue by the shortest way. Other appliances must not be
attached to the same flue. It is not recommended a permanent connection with water supply
through the filling up valve so that in case of valve untightness the pressure might increase. Max.
overpressure is 0,2 MPa.
Boiler room must have a good ventilation.
Assembly of boiler can be done by specialists in compliance with the valid local standards.
Minimum return water temperature at the inlet to the boiler is 60 °C.
It is recommended the boiler is fitted together with the accumulation tank which must correspond
to the standard EN 303-5.
The boiler must be installed together with four-way valve /duomix/. The valve secures that return
water temperature is not less than 60° and protect the boiler against the low temperature
corrosion.
