GENERAL

GENERAL WARNINGS

Each generator is provided with a manufacture plate that can be found in the envelope with the boiler documents.
The plate lists:

 Serial number or identification code;

 Rated thermal output in kcal/h and in kW;

 Furnace thermal output in kcal/h and in kW;

 Types of fuels that can be used;

 Max operating pressure.

A manufacture certificate is also provided which certifies the hydraulic test positive performance.
The installation must be performed in compliance with the regulations in force by professionally qualified personnel. The term 
“professionally qualified personnel” means persons with specific technical skills in the sector of heating system components.
Incorrect installation may cause damage to persons, animals or objects for which the manufacturer cannot be held responsible.

At the first start up, all regulation and control devices positioned on the control panel should be checked for efficiency.
The guarantee shall be valid only upon compliance with the instruction given in this manual.
Our boilers have been built and tested in observance of EEC requirements and, as a consequence, CE-marked.
EEC directives are as follows:

 

Directive on Gas

 90/396/EEC

 

Directive on Output

 92/42/EEC

 

Directive on Electromagnetic Compatibility

 89/336/EEC

 

Directive on Low Voltage

 73/23/EEC

IMPORTANT: 

This boiler has been designed to heat hot water at a temperature inferior to the boiling temperature

at atmospheric pressure and must be connected to a heating plant and/or a domestic hot water plant
within the limits of its performance and output.
