INSTRUCTIONS PERTAINING TO THE USER

1. INSTRUCTIONS PRIOR TO INSTALLATION

This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler must be connected to a central heating system and to a domestic hot water supply system in compliance with its performances and output power. Have the boiler installed by a Qualiﬁ ed Service Engineer and ensure the following operations are accomplished:

a) careful checking that the boiler is ﬁ t for operation with the type of gas available. For more details see the notice on the

packaging and the label on the appliance itself.

b) careful checking that the ﬂ ue terminal draft is appropriate; that the terminal is not obstructed and that no other appliance

exhaust gases are expelled through the same ﬂ ue duct, unless the ﬂ ue is especially designed to collect the exhaust gas coming from more than one appliance, in conformity with the laws and regulations in force.

c) careful checking that, in case the ﬂ ue has been connected to pre-existing ﬂ ue ducts, thorough cleaning has been carried

out in that residual combustion products may come off during operation of the boiler and obstruct the ﬂ ue duct.

d) to ensure correct operation of the appliance and avoid invalidating the guarantee, observe the following precautions:

1. Hot water circuit:

1.1. If the water hardness is greater than 20 °F (1 °F = 10 mg calcium carbonate per litre of water) a polyphosphate or

comparable treatment system responding to current regulations.

1.2. Domestic Hot Water circuit must be thoroughly ﬂ ushed after the installation of the appliance and before its use.

2. Heating circuit

2.1. new system

Before proceeding with installation of the boiler, the system must be cleaned and ﬂ ushed out thoroughly to elimi-

nate residual thread-cutting swarf, solder and solvents if any, using suitable proprietary products. To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non alkaline. The recommended products for cleaning are: SENTINEL X300 or X400 and FERNOX heating circuit restore. To use this product proceeding strictly in accordance with the maker’s directions.

2.2. existing system

Before proceeding with installation of the boiler, the system must be cleaned and ﬂ ushed out to remove sludge and

contaminants, using suitable proprietary products as described in section 2.1. To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non-alkaline such as SENTINEL X100 and FERNOX heating circuit protective. To use this product proceeding strictly in accordance with the maker’s directions. Remember that the presence of foreign matter in the heating system can adversely affect the operation of the boiler (e.g. overheating and noisy operation of the heat exchanger).

Failure to observe the above will render the guarantee null and void.

2. INSTRUCTIONS PRIOR TO COMMISSIONING

Initial lighting of the boiler must be carried out by a licensed technician. Ensure the following operations are carried out: a) compliance of boiler parameters with (electricity, water, gas) supply systems settings. b) compliance of installation with the laws and regulations in force. c) appropriate connection to the power supply and grounding of the appliance.

Failure to observe the above will render the guarantee null and void. Prior to commissioning remove the protective plastic coating from the unit. Do not use any tools or abrasive detergents as you may spoil the painted surfaces.

• To adjust the CH and D.H.W. temperature, press the +/- respective buttons as described in section 4.

Warning: During initial lighting, until the air contained in the gas pipes is not released, the burner may fail to light immediately and that may cause a ‘blockage’ of the boiler. Under such circumstances we recommend you to repeat the ignition

procedure until the gas is delivered to the burner, and press

button, for at least two seconds, to set the operating boiler mode (see section 3.2)

5. FILLING THE BOILER

IMPORTANT: Regularly check that the pressure displayed by the pressostat (ﬁ gure 3) is 0.7 to 1.5 bar, with boiler not op-

erating. In case of overpressure, open the boiler drain valve. In case the pressure is lower open the boiler ﬁ lling tap. We recommend you open the tap very slowly in order to let off the air. During this operation, the gas boiler must be in “OFF” mode (press the

button - See section 3.2).

6. TURNING OFF THE BOILER

The electric supply to the boiler must be removed in order to switch it OFF. With the gas boiler in “OFF” mode (section 3.2), the display reads out “OFF” but the main board is still supplied.

7. GAS CHANGE

These boilers set for natural gas can be converted to work with LPG. Any gas change must be effected by a Qualiﬁ ed Service Engineer.

8. PROLONGED STANDSTILL OF THE SYSTEM. FROST PROTECTION

We recommend you avoid draining the whole system as water replacements engender purposeless and harmful limestone deposits inside the boiler and on the heating elements. In case the boiler is not operated during wintertime and is therefore exposed to danger of frost we suggest you add some speciﬁ c-purpose anti-freeze to the water contained in the system (e.g.: propylene glycole coupled with corrosion and scaling inhibitors). The electronic management of boilers includes a “frost protection” function in the central heating system which operates the burner to reach a heating ﬂ ow temperature of 30° C when the system heating ﬂ ow temperature drops below 5°C.

The frost protection function is enabled if:

* electrical supply to the boiler is on; * the gas service cock is open; * the system pressure is as required; * the boiler is not blocked.
