OPERATING DESCRIPTION
By turning off the main switch, if the thermostats are closed, the
voltage reaches the control box.
Then the speed decreases to the value P2 and the ignition takes
place.
If, instead, the fan starts but the flame does not appear at the end
of the safety time, the burner locks out.
Unlock and wait for a new ignition attempt.
If the flame ignition is still missing, this may be caused by the gas
failing to reach the combustion head within the safety time (3s).
The combustion air flow rate can be adjusted by changing the
number of motor rpm.
The proportional gas train, depending on the pressure detected in
the ventilation circuit, dispenses the correct amount of fuel.
Therefore, the power delivered is adjusted through the variation of
the engine rotation speed.
When the ignition is completed, do to the full control of the burner.
