PIPE INSTALLATION
Pipe installations
The BioComp -boiler has been designed to operate without an accumulator tank. The boiler
has a large water capacity and it has its own heat exchanger for production of domestic hot
water. It is, however, possible to install an accumulator tank if the boiler is used intermittently
or momentary peaks in consumption such require. The thermostats, overheating protection
equipment and other safety devices are installed according to the burner instructions. Before the
boiler installation, the heating network must be flushed and tested using a hydraulic pressure
test. The sealing of the connections must be checked after the installation. The factory is not
responsible for damage caused by leaking connections.
NOTE! The boiler circulation ensures that the return water temperature is high enough (min 70
°
C.).
This is important in order to ensure good combustion conditions and to prevent corrosion to the
boiler body caused by the cold return water (see installation example below).
