INSTRUCTIONS FOR
INSTALLATION
3.1

GENERAL RECOMMENDATIONS

ATTENTION!
This boiler must only be employed for its explicitly
intended use. Any other use must be considered
improper and therefore dangerous.
This boiler is used to heat water to below boiling
temperature in atmospheric pressure.
ATTENTION!
The appliances are designed to be installed inside
buildings only in suitable technical compartments,
and also outdoors in a completely open place.
Before connecting the boiler, have professionally
authorised company:
a) Accurately washing all of the pipes in the system
to remove any residues or sediments could stop
the boiler form running efficiently, even in terms
of health and hygiene.
b) Making sure the boiler is set up to operate with the
available type of fuel. The type of fuel is stated on the
packaging and technical characteristics plate.
c) Make sure that the chimney/flue has an adequate
draught, that it is not choked, and that there are no
other exhausts for other appliances, unless the flue
is designed for multiple utilities, in accordance with
standard specifications and requirements in force.
Only once this check has been carried out can the
fitting between boiler and chimney/flue be set up.
ATTENTION!
In rooms with aggressive vapour or dust, the
appliance must operate independently of the air in
the room of installation!
ATTENTION!
The appliance must be installed by an authorised
company possessing professional-technical
qualifications in accordance with the law, who, under
his/her own responsibility, enforces the observance of
regulations according to the rules of good practice.
ATTENTION!
Assemble the appliance in observance of the minimum
required distances for installation and maintenance.
The boiler must be connected to a heating system
compatibly with its specifications and power.

REGULATIONS FOR INSTALLATION

Installation must be carried out by a
who is in charge of enforcing observance of all local and/or national
laws published in the Official Gazette, as well as all applicable technical
regulations.
3.3 PREVENTATIVE CHECKS AND
ADAPTATION OF THE SYSTEM
When the appliance is installed on existing systems, make sure that:
- The flue is suitable for condensation appliances, for the temperatures
of the combustion products, calculated and built in accordance with
regulations in force. That is it a straight as possible, water-tight and
insulated and does not have any obstructions or constrictions.
- The flue is equipped with an attachment to evacuate the condensation.
The boiler room is equipped with a pipe for the evacuation of the
condensation produced by the boiler.
- The electrical system is built in accordance with specific regulations
and by professionally authorised company.
- The flow rate, head and direction of flow of the circulation pumps is
appropriate.
- The fuel feed line and any existing tanks are set up in accordance with
regulations in force.
- The expansion vessels ensure complete absorption of the dilation of
the fluid contained in the system.
- Slurry and build-up have been cleaned out of the system.
3.4 protection devices when using a PHE (must be fitted)
(not supplied by Alpha)
1 Safety thermostat: this is designed to stop the boiler if the safety
thermostat installed on the boiler fails to operate correctly. It must
have an IMMOVABLE calibration of < 100°C.
2 Minimum pressure switch: this is designed to stop the boiler if
the minimum operating pressure drops (can be calibrated between
0.5 - 1.7 bar). It must be manually reset.
3 Safety pressure switch: this is designed to stop the boiler if the
maximum operating pressure is reached (can be calibrated between 1 -
5 bar).
3.3 Pressure Relief Valve correctly sized for the installation.
3.5 Control devices when using a PHE (must be fitted)
1 (pressure gauge -( not supplied by Alpha) with (12) damper pipe
and (11) pressure gauge valve: it indicates the current pressure in
the boiler, it must be graduated in 'bar', its full scale must match the
maximum operating pressure and be equipped with a three-way
valve with an attachment for the control pressure gauge.
contained in the boiler, it must be graduated in centigrade with a
full scale of no more than 120°C.
2 Spare sockets: approved for the inclusion of control devices.
3 1¼" stub pipes: for the inclusion of safety valves.
4 flow switch: Not supplied by Alpha this is designed to stop the
boiler in case of low flow inside the primary circuit.
5 Approved expansion vessel: this absorbs the increase in
volume of water in the system following an increase in
temperature. Not supplied by Alpha.
6 y strainer.
7 Modulating pump (Not included in the kit).
8 hydraulic separator (Not included in the kit).
9 Automatic air vent. Not supplied by Alpha.
10 Drain cock. Not supplied by Alpha.
