Rated thermal capacity check
After have checked the proper injectors installation and the inlet gas pressure, check the thermal capacity. With the
volumetric method with a chronmeter and a gas counter. The check consist in calculating the consumption in a
determinate time unit. The result must be compared with technical data schemes. (See table page 4).
Flame check
You can check both the main burner’s flame and the pilot burner‘s flame with a sight examination through the peephole
located at the entrance side of the burner as indicated in picture 10. Their aspect must be a steady flame and not return
to ignition.

Control evacuation of combustion gases and the smoke detector
To check the right working of the smokes sensor switch off the burn gas circuit. The simulation must be carried out by
inserting a pipe 50 cm long of a suitable diameter which must be plugged with a sheet metal.
The burner and the pilot must go out in two minutes from the moment in which the pipe has been plugged.
If this does not happen check again the connection of the fastons. It may be also necessary to change the piece.
