Gas Connection; Electric Connection - Beretta BOILER B.A.I Série Manuel D'installation Et D'utilisation

4.
Before connecting appliance to gas pipe network, check the
following:
• regulations in force are met
• gas type used is the same as set for appliance operation
• pipes are clean.
After installation make sure that all the joints have been made
airtight conforming to standard installation practices.
Gas must be piped externally. If the pipe goes through a wall it
must go through the central opening in the lower part of the
template. It is recommended to install an appropriately sized filter
on the gas line in case gas from the mains contains some small
solid particles.
5.
Connect the appliance to the mains electricity supply with a switch
featuring a distance of at least 3,5 mm (EN 60335-1, category III)
between each wire.
The appliance uses alternating current at 230 Volt/50 Hz, has a
power input of 85W (B.A.I.) and 125W (B.S.I.) and complies with
EN 60335-1.
The appliance must be connected to an efficient earth circuit,
according to current legislation and bylaws.
Live and neutral (L-N) connections should also be respected.
The earth conductor must be a couple of cm longer than the
others.
Gas and/or water pipes may not be used to earth electrical
equipment.
The installer is responsible for making sure that the appliance
has an adequate earthing system; the manufacturer shall not
be held liable for eventual damages caused by incorrect usage
or failing to earth the boiler.
Use the supplied power cable to connect the boiler to the mains
power supply.
When replacing the power cable, use a HAR H05V2V2- F cable,
3 x 0.75 mm 2 , max. external Ø 7 mm and proceed as follows:
- prise out the control cover panel with a screwdriver (fig. 3)
- remove the screws fixing the shell (fig. 4)
- remove the screws fixing the panel and turn it (fig. 5)
- loosen the fixing screw and remove the cable connector cover
(fig. 6)
- fit the T.A. cable into the relative cable clamp on the frame (fig. 7)
- then connect the terminals as shown on the self-adhesive plate
attached to the boiler (fig. 8)
Connect the ambient thermostat and/or time clock as shown in the
electrical diagram on page 139.
6.
FILLING AND EMPTYING THE SYSTEM
Heating system (fig. 9)
The central heating system can be filled up once the water mains
have been connected up.
This must be done while the installation is cold by:
- giving two or three turns to the cap of the automatic air vent
valve (C) to open it
- making sure the cold water stopcock is open (B)
- opening the filling stopcock (D) until the pressure measured by
the thermohydrometer is between 1 and 1,5 bar.
Close the filling stopcock after filling it up.
The boiler is equipped with an efficient air separator so that there
is no need to do anything manually.
The burner only ignites when air venting has finished.

Empty the system by:
- switching off the boiler
- close the on-off taps of the heating and domestic hot water
system
open the automatic air vent valves
-
- loosening the valve to empty boiler (E)
- e mptying out the bottom parts of the system.
DHW system emptying (fig. 9)
The hot water system must be emptied every time there is risk of
freezing by:
- turning off the stopcock at the mains
- unscrew the cap on the hose adapter
- connect a plastic hose to the hose adapter of the storage boiler
drain valve (A)
- open the valve drain device
- turning on all the hot and cold taps
- emptying out the bottom parts.
ATTENTION
Drainage from the safety valve (B) must be connected to an
adequate drainage system. The manufacturer shall not be held
liable if the safety valve should eventually cause flooding.
7.
Boiler is equipped with a system controlling proper exhaustion of
combustion products – fume thermostat (14, fig. 22a page 131); in
case of abnormality, this system immediately stops appliance
operation.
Place function selector on OFF/RESET to restore operation and
take to the position required.
If abnormality persists, do not perform any action, but immediately
call Technical Service; technicians will correct fume exhaustion
defect and test operation.
Refer to regulations in force for burnt product exhaustion.
It is compulsory using rigid pipes, junctions between elements
must be tight and all components must be resistant to tempe-
rature, condensates and mechanical stresses.
Device controlling proper fume exhaustion must never be
deactivated. Use original spare parts only when replacing it.
Exhaustion ducts which are not insulated can be dangerous.
Openings for burning air must comply with regulations in force.
If condensates are produced, insulate exhaustion duct.
Fig. 10 shows the top view of boiler with reference measures
for fume outlet distance between centres, from boiler support
plate.
8.
Refer to regulations in force for exhaustion of combustion products.
Boiler is provided for without fume exhaustion/air suction kit, since
forced draught sealed chamber accessories can be used, as they
better adapt to installation characteristics.
For fume extraction and burning air restoration in boiler, use original
pipes or other EC-certified pipes with equivalent characteristics;
check connection is correct as shown on instructions fume
accessories provided for with.
More appliances can be connected to a single chimney, provided
that all appliances are sealed chamber type.
Boiler is a C-type appliance (sealed chamber) and must be safely
connected to fume exhaustion duct and burning air suction duct,
both getting outside; appliance cannot operate without these ducts.
