3.6.4 Common technical data for GFI 48/70/89 pilot burner
NOTICE
The electrical data are identical for all devices, only the air and gas volume flows differ.
Design A: Power supply voltage connection
Electrical data 120/127/220/230 VAC; -15/+10% (within the scope of the EU
Gas Appliances Directive), cf. rating plate
240 VAC; -20/+5% (outside the scope of the EU Gas Appli-
ances Directive), cf. rating plate
Mains frequency 50/60 Hz
Power consumption 10 VA flame scanner when UN = 230 V, 230 VA ignition trans-
former,
10 VA flame scanner when UN = 120 V, 192 VA ignition trans-
former,
Ignition transformer duty cycle ED= 50% on 2 min. (1’ on; 1’ off) 45 °C when UN=230V
ED= 15% on 1 min. (9”on; 51” off) -20°C<Ta<60°C when
UN=120V
