Air Adjustment - Ecoflam DUAL 1 Manual De Instrucciones

CALCULATING THE BURNER CAPACITY
To calculate the burner's capacity in kW, proceed as follows: Check the gas flow rate (in liters) on
the counter and the time of the reading in seconds.
Proceed with the calculation using the following :
When the thermostats are closed, the gas leakage control device checks the valve seals by pressurizing the circuit between the two
gas valves. When test pressure is reached the device remains in stand-by for about 25 seconds. At the end of the test the yellow pilot
light on the control device lights up and the burner is enabled to carry out the start-up cycle. If the seal on one of the valves is
faulty and this causes a drop in test pressure, the device puts the system into the safety condition and the red pilot right on the devi-
ce lights up. The flame control device starts the burner fan to carry out prewashing of the combu-
stion chamber,checking fan air pressure via the air pressure switch. After preventilation the igni-
tion transformer starts operating, generating a spark between the electrodes and simultaneously
the gas valves open (safety gas valve VS and first stage operating valve VL). If the flame does not
ignite or goes out, total safety is ensured by an ionization detection probe. The safety time limit
in the event of no flame is less than 2 seconds at start-up and less than 1 during operation. In the
event of no gas being supplied or of a considerable drop in pressure the minimum gas pressure
switch interrupts burner operation. About 20/30 seconds after ignition the flame control device commands operation of the second
stage via the gas valve and air servocontrol, thus taking the burner to maximum power.
