Installation - Beretta BV 120 Installer Manual

Installation

We recommend using the following accessories:
- Water expansion vessel kit
- Water connection kit
These are specifically designed for quick, easy installation of the BV 120 and BV 160 boilers.
The BV 120 and BV 160 boilers are fitted with a safety valve
fitted on the cold water intake, with a branch for connecting to the
water expansion vessel (AV).

When using BV 120 and BV 160 boilers, we recommend fitting a
4 litre water expansion vessel.
To install the expansion vessel, unscrew the cap on the relevant
connection (AV) on the safety valve, and connect the vessel.
Connect the safety valve to the drain pipe supplied, which must
be left out in the open and installed with a continuous fall.
We recommend fitting a tap upstream of the cold water intake
(EAF) which, if needed, makes it possible to isolate the boiler
from the water system.
BV 120 and BV 160 boilers are fitted with a non-return valve
connection fitted on the pipe coil return (RS).
This pipe fitting has a threaded connection (Cl) to use to fill the
system. Unscrew the cap on the (Cl) connection using a CH 10
spanner and connect the hose to fill the system.

- Put the bulb into the cable clamp.

- Repeat the same operation for the bulb of the thermometer, if
fitted.
- Being careful not to lift the bulb from the bottom of the housing,
slide the sensor cable or capillary tube for the thermostat
through the cable clamp, resting the cover (C) on the boiler.
