INSTALLATION INSTRUCTIONS

IMPORTANT: The packing elements (foamed polystyrene, plastic bags) must be kept out of the reach of children, as

they are a potential source of danger.

This boiler has been designed to respond to European standards. It has been manufactured with greatest care, in compliance with

safety regulations. Each appliance has been tested when working, and the inspector who carried out the tests has signed the

warranty certificate enclosed with the appliance documents.

Check that the boiler supplied corresponds perfectly with its intended use.

-Indications of the type of boiler and gas to be used are given on the plate fitted behind the control panel, outside the boiler and on

the boiler packaging.

The products described in this manual have been correctly manufactured in conformity with current legislation.

The boilers are manufactured in accordance with EN specific safety Standards for fuel gas, as per Directive 90/396/CEE regarding

gas appliances and Directive 92/42/CEE regarding performance levels of new hot water boilers, that are driven by liquid or gas

fuels.

This appliance must be installed in accordance with the following Statutory Regulations and British Standards Codes of Practice:

Building Regulations (England and Wales). The Buildings Standards (Scotland) Regulations. Gas Safety (Installation and Use)

Regulations 1984. Current I.E.E. Wiring Regulations and Local Water Authority By-Laws.

Codes of practice: BS.6891 –Installation of low pressure gas pipework;

BS.6798 –Installation of gas fired hot water boilers of a rated input not exceeding 60 kW.

BS.5449:1 –Forced circulation hot water system (domestic central heating system smallbore and microbore).

BS.5546 –Installation of gas hot water supplies for domestic purposes (2

family gases).
