(2)
Sound pressure measured in manufacturer's combustion laboratory, with burner operating on test boiler and at maximum rated output. The
sound power is measured with the “Free Field” method, as per EN 15036, and according to an “Accuracy: Category 3” measuring accuracy,
as set out in EN ISO 3746.

ACCESSORIES

:
• LONG HEAD KIT:
Burner TECNO 34-L TECNO 44-L
Code 3010426 3010425
• CLEAN CONTACT KIT code 3010419
• KIT GROUND FAULT INTERRUPTER code 3010448
• KIT HOURCOUNTER code 3010450
• KIT POST-PURGING code 3010453
• RADIO DISTURBANCEPROTECTION KIT code 3010386

If the burner is installed in places particularly subject to radio disturbance (emission of signals exceeding 10 V/m) owing to the presence of an
INVERTER, or in applications where the length of the thermostat connections exceeds 20 metres, a protection kit is available as an interface
between the control box and the burner.
• DEGASSING UNIT
It may occur that a certain amount of air is contained in the light oil sucked up by the pump. This air may originate from the light oil itself as a con-
sequence of depressurisation or air leaking past imperfect seals.
In double-pipe systems, the air returns to the tank from the return pipe; in single-pipe systems, the air remains in circulation causing pressure var-
iations in the pump and burner malfunctions.
For this reason, we advise installing a degassing unit near the burner in single-pipe installations. Degassing units are provided in two versions:
