IMPORTANT: Before carrying out any work on the boiler's electrical installation, always ensure

it is disconnected from the mains.

IMPORTANT: Make

sure

that none of the mains cables come into contact with a hot surface

(e.g. flue).

3.8

Example of an installation with a buffer tank

The Lignum NG boiler is equipped with an electronic control that can govern a circuit with buffer

tank, with an external circulation kit to prevent condensation in the heat exchanger. The heating

circuit must be regulated and controlled with an external regulator (not included in the boiler

control).

The figure below shows an example of a hydraulic diagram of a buffer tank heating installation:

VS

:

Heating safety valve

VR

:

Anti-condensation thermostatic valve

VA:

Drain valve

BC

:

Heating pump

BT:

Buffer tank

VDT:

Temperature relief

valve

VC:

Heating expansion vessel

BCD:

Direct circuit pump

BCM:

Mixed circuit pump

P:

Automatic air bleed valve

IMPORTANT: It is obligatory and essential to install a heating water buffer tank.
