Forced flue

Balanced flue room sealed appliance

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.

Direct electronic ignition

NG: 1.13 kPa, LPG 2.75 kPa

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).

Valve opens at 2060 kPa, and closes at 1470 kPa
