Exhaust system
Forced flue
Frost protection
Fitted as standard. Frost protection operates automatically, as long as the appliance is connected to the electrical power supply, by activating when the temperature inside the unit drops below 3.5 °C, and turns off once the temperature inside the unit reaches 7 °C.
Ignition system
Direct electronic ignition
Injector sizes
A16: NG: 0.9, 1.50, LPG: 0.71, 1.09
 
A20-A26: NG: 1.08, 1.80, LPG: 0.73, 1.12
Line pressure (min.)
NG: 1.13 kPa, LPG 2.75 kPa
Line pressure (max.)
3.5 kPa (maximum standing pressure under abnormal intermittent conditions is 5.0 kPa).

In the case of commercial metering, (i.e. 35-37 kPa coming in), there may be a requirement to regulate the incoming pressure down).
