FUNCIONAMIENTOOPERATION
Single-stage burners
z
Turn on the burner using the switch
A
on the control panel (Fig. 48: the control panel of the single stage burner is only pro-
vided with the power switch and the fuse).
z
Make sure that the apparatus is not in shutdown condition and if so, release by using the release button
S
on the burner
cover (see Fig. 49).
z
Make sure that the set of thermostats (or pressure-switches) triggers burner operation.
z
The burner starting cycle begins and the apparatus starts the burner fan while the ignition transformer switches on at the
same time.
z
At the end of pre-ventilation, the fuel solenoid valve receives input and the burner switches on.
z
The ignition transformer remains switched on for a few seconds after the ignition of the flame (post-ignition time) after which
it is disconnected from the circuit.
Double-stage burners
z
Turn on the burner using the switch
A
on the control panel (Fig. 48).
z
Make sure that the apparatus is not in shutdown condition and if so, release by using the release button
S
on the burner
cover (see Fig. 49).
z
Make sure that the set of thermostats (or pressure-switches) triggers burner operation.
z
The burner starting cycle begins and the apparatus starts the burner fan while the ignition transformer switches on at the
same time; pre-ventilation lasts for 13 or 25 seconds depending on the apparatus provided with the burner.
z
At the end of pre-ventilation, the fuel solenoid valve (1st stage, EVG1) receives input as signalled by the illumination of the
signal light
H
on the control panel and the burner starts.
z
The ignition transformer remains switched on for a few seconds after the ignition of the flame (post-ignition time), after
which it is disconnected from the circuit and the corresponding signal light switches off.
z
In this way, the burner is lit at low flame; after 5 or 15 seconds (depending on the apparatus installed) two-stage operation
begins and the burner is either automatically brought to high flame (light
G
on) or remains burning at low flame (light H on)
depending on the requests received from the system.
