Outdoor installation:
the boiler can be installed outdoor, in a partially
protected place (i.e. a place where the boiler is not exposed to direct
contact or infiltration of rain, snow or hail). The boiler is fitted as
standard with an automatic anti-freeze system that actives when
the water temperature in the primary circuit falls below 6°C.
To take
advantage of this protection, based on the burner operation, the boiler
must be able to switch itself on; any lockout condition (i.e. due to a
lack of gas or electrical supply, or the intervention of a safety device)
therefore deactivates the protection.
FIXING THE BOILER
The
FASTECH
boiler has been designed and produced to be installed
in heating and domestic hot water production systems. The position
and dimensions of the hydraulic fittings are stated in the illustrations.
- Position the support plate using a spirit level. Check it is horizontally
level and that the boiler support surface is flat. If necessary, add
shims to level the surface correctly.
-
Mark the fixing points referring to the indication “plug the hole”.
- Remove the plate and drill the holes.
- Fit the plugs.
- Use a spirit level to check the plate is level.
-
Hook up the boiler to the plugs (fig. 4).
3.7
Hydraulic connections (fig. 5)
Connect the fittings and seals supplied with the system.
Connect the boiler to the system by inserting both the domestic water
shut-off valve and the heating system shut-off valves. A specific heating
system valve kit and heating valve kit with filter are available.

The choice and installation of system components is left to the
discretion of the installer, who must operate according to the
rules of good technical practice and current legislation.
If the supply water has a total hardness of between 25°F and
50°F, install the domestic water kit. If the total hardness is above
50°F, the kit progressively decreases in efficiency and a higher
performing appliance or a water softening system should be
installed. In case of total hardness below 25°F, a suitably sized
filter should be installed if the water supplied form the mains is
not perfectly clean/cannot be cleaned.
The boiler safety valve outlet must be connected to an adequate
collection and drainage system. The boiler manufacturer declines
all liability for any flooding caused by the safety valve.
A carry case kit is available so that connections can be made
quickly, without wasting time on each system.
3.8
Electrical connections (fig. 6 - 7 - 8)
The
FASTECH
boiler is factory-wired and the electrical power cable
is already connected. The room thermostat/s (TA) must simply be
connected to the relative terminals.
- Turn the main system switch to “OFF”.
-
Unscrew the case fixing screws (
A
).
- Move the bottom of the case forward and then upwards to detach
it from the frame.
- Unscrew the panel screws (
B
).
- Turn the control panel forwards.
- Open the cover (
C
) to access the control board.
The boiler operates with alternating current at 230 V/50 Hz and is
compliant with standard EN 60335-1.
Low-voltage safety room thermostat (voltage-free contact).
When using a phase-phase power supply, use a tester to
determine which of the two wires has the greater potential
compared to the earth and connect it to the L terminal. Connect
the remaining wire to the N terminal.
The boiler can also operate with a phase-neutral or phase-phase
power supply. For floating power supplies, i.e. those which
have no earth connection, use an insulation transformer with a
secondary circuit connected to the earth.
The earth wire must be approximately 2 cm longer than the other
wires.
YOU MUST:
- use a general trip-switch to disconnect the line in compliance with
Italian CEI-EN 60335-1 standards (contact opening at least 3.5
mm, category III)
-
use cables with a cross-section of ≥ 1.5 mm
2
and respect the L
(phase) - N (neutral) connection
- ensure that the amperage on the switch is adequate for the boiler’s
electrical power rating. Please refer to the technical data to check
the electrical rating of the model installed
-
connect the appliance to an efficient earthing system
- ensure that the power socket can be accessed after installation.
Do not use gas or water pipes to earth this appliance.
The manufacturer declines any liability for damage caused by
failure to comply with the wiring diagrams.
The installer is responsible for ensuring that the appliance has an
efficient earthing system. The manufacturer declines all liability
for any damage caused by a faulty earthing circuit or the lack
of an efficient earthing circuit.
3.9
Gas connections
The
FASTECH
boilers must be connected to the main gas supply in
compliance with current installation standards.
Before connecting the appliance, ensure that:
- the type of gas is compatible with the boiler model being installed.
- all pipelines are thoroughly cleaned.
The gas supply system must be suited to the flow rate of the
boiler and must be fitted with all safety and control devices as
envisaged by current standards. A suitable sized filter should
also be used.
At the end of installation, check all connections are properly
sealed.
3.10 Flue gas outlet and combustion air suction
FASTECH KI (fig. 9)
The discharge pipeline and connection to the flue must comply with
current local and national standards and legislation.
Use rigid ducts. Joints between parts must be airtight. All components
must be resistant to high temperatures, condensate and mechanical
stress.
These boilers are equipped with a fumes thermostat positioned
on the right side of the hood. If combustion products are returned,
this device immediately shuts down operation of the boiler.
The combustion air vents must comply with current technical
standards.
Discharge ducts without insulation are a potential source of
danger.
Do not seal off or reduce the size of the air vents in the room
where the boiler is installed.
FASTECH KIS (fig. 10a-b-c-d-e-f-g-h)
The boilers must have appropriate ducts for fumes outlet and air intake,
according to the type of installation. Ducts are an integrant part of
the boiler but are supplied in separate kits, for improved installation
flexibility.
The maximum lengths of the ducts refer to flue systems available
in the catalogue.
“FORCED OPEN” INSTALLATION (TYPE B22P-B52P)
Fumes outlet duct ø 80 mm (fig. 10c)
The fumes outlet duct can be aimed in the most suitable direction for
installation needs. To install follow the instructions supplied with the kit.
In this configuration, the boiler is connected to the Ø 80 mm fumes
outlet duct by means of a Ø 60-80 mm adaptor.
When necessary, the flue gas flange (
A
), must be removed or replaced
using a screwdriver as a lever.
In this case, the combustion supporting air is taken from the
room in which the boiler is installed, which must be a suitable
and ventilated technical room.
Non-insulated fumes outlet ducts are potential sources of danger.
It is appropriate to install a condensate collector and specific
pipes. In this case realize an inclination of 3° to the condensate
collector.
