Table of Contents

The following remarks and instructions are addressed to Service Engineers to help them carry out a faultless

installation. Instructions regarding lighting and operation of the boiler are contained in the 'Instructions per-

taining to the user' section.

Note that installation, maintenance and operation of the gas appliances must be performed exclusively by

quali ed personnel in compliance with current standards.

Please note the following:

• Install the boiler in a permanent ventilated central heating boiler room.

• This boiler can be connected to any type of convector plates, radiators, thermoconvectors. Design the

system sections as usual though taking into account the available output / pump head performances.

• Do not leave any packaging components (plastic bags, polystyrene, etc.) within children's reach as they are

a potential source of danger.

• Initial lighting of the boiler must be effected by a Quali ed Service Engineer.

• Make sure that the room where the boiler is installed has a suf cient supply of air to ensure complete

combustion of the gas consumed by the appliance. Install unblockable ventilation grilles as necessary in

accordance with the Rules in force.

• Connect the boiler directly to an ef cient ue to vent all fumes and combustion gases outdoors. Make sure

that the pipe connecting the boiler to the ue is not smaller in diameter than the boiler's ue outlet. Make

sure that the ue is in good condition and free from holes or cracks that could reduce draw.

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

WARNING -

Before Leaving

Test the operation of the appliance after installation is complete. Check all connections for gas leaks with soap

and water. DO NOT use a naked ame for detecting leaks. When satis ed with the boiler, please instruct the

user on the correct method of operation. In case the appliance fails to operate correctly after all checks have

been carried out, refer to the authorised service provider in your area".

9. 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.

IMPORTANT! The following components are not installed in the boiler as supplied. It is the installer's

responsibility to provide them:

• Expansion vessel;

• Pressure safety valve;

• Circulation pump;

• Filling system cock.

Before connecting the boiler have the following operations effected:

a) careful checking that the boiler is 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 ue terminal draft is appropriate; that the terminal is not obstructed and that no

other appliance exhaust gases are expelled through the same ue duct, unless the ue is especially desig-

ned 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 ue has been connected to pre-existing ue ducts, thorough cleaning

has been carried out in that residual combustion products may come off during operation of the boiler and

obstruct the ue duct.
