3b) FIRING WITH GAS, LIGHT OIL OR OTHER FUELS
GENERAL



The burner shall be installed by qualified personnel and in compliance

with regulations and provisions in force; wrong installation can cause

injuries to people and animals, or damage to property, for which the

manufacturer cannot be held liable.



Before installation, it is recommended that all the fuel supply system

pipes be carefully cleaned inside, to remove foreign matter that might

impair the burner operation.



Before the burner is commissioned, qualified personnel should inspect

the following:

a the fuel supply system, for proper sealing;
b the fuel flow rate, to make sure that it has been set based on the firing

rate required of the burner;

c the burner firing system, to make sure that it is supplied for the desig-

ned fuel type;

d the fuel supply pressure, to make sure that it is included in the range

shown on the rating plate;

e the fuel supply system, to make sure that the system dimensions are

adequate to the burner firing rate, and that the system is equipped with

all the safety and control devices required by the regulations in force.



When the burner is to remain idle for some time, the fuel supply tap or

taps should be closed.

SPECIAL INSTRUCTIONS FOR USING GAS

Have qualified personnel inspect the installation to ensure that:
a the gas delivery line and train are in compliance with the regulations

and provisions in force;

b all gas connections are tight;
c the boiler room ventilation openings are such that they ensure the air

supply flow required by the current regulations, and in any case are

sufficient for proper combustion.



Do not use gas pipes to earth electrical equipment.



Never leave the burner connected when not in use. Always shut the

gas valve off.



In case of prolonged absence of the user, the main gas delivery valve

to the burner should be shut off.

Precautions if you can smell gas

a do not operate electric switches, the telephone, or any other item likely

to generate sparks;

b immediately open doors and windows to create an air flow to purge the

room;

c close the gas valves;
d contact qualified personnel.



Do  not  obstruct  the  ventilation  openings  of  the  room  where  gas

appliances  are  installed,  to  avoid  dangerous  conditions  such  as  the

development of toxic or explosive mixtures.
