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/or to a domestic hot water supply system in compliance with its performances and output power.

The boiler must be installed by a Qualified Service Engineer ensuring that the following operations are carried out:

a) Careful checking that the boiler is fit 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 flue terminal draft is appropriate; that the terminal is not obstructed and that no other appliance exhaust gases are expelled through the same flue duct, unless the flue is especially desi - gned to collect the exhaust gas coming from more than one appliance, in conformity with the standards and regulations in force.

c)Careful checking that, in case the flue has been connected to pre-existing flue ducts, thorough cleaning has been carried out in that residual combustion products may come off during operation of the boiler and obstruct the flue duct.

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

1.Hot water circuit:

If the water hardness is greater than 20 °F (1 °F = 10 mg calcium carbonate per litre of water) a polyphosphate or comparable treatment must be used in response to current regulations.

2.Heating circuit

2.1.New system

Before proceeding with installation of the boiler, the system must be cleaned and flushed out thoroughly to eliminate 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. The use of this product must be strictly in accordance with the maker’s directions. Finally the system must be dosed with a suitable inhibitor at 1% system volume.

2.2. Existing system

Before proceeding with installation of the boiler, the system must be cleaned and flushed 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.

Remember that the presence of foreign matter in the heating system can adversely affect the operation of the boiler (e.g. overheating, noisy operation, or failure of the heat exchanger may occur).

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

2. INSTRUCTIONS PRIOR TO COMMISSIONING

Initial lighting of the boiler must be carried out by a qualified service engineer. 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 standards and regulations in force.

c)Appropriate connection to the power supply and earthing of the appliance.

Failure to observe the above will render the warranty 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 damage the painted surfaces.
