NG - 1.13kPa, 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.
Nominal operating pressure: 300-1000 kPa
Activation flow rate: 1.5 litres per minute
Please note: If the water inlet pressure or flow rate drops below the minimum values stated above, operation of the INFINITY is not guaranteed. The unit requires both minimum flow rate and pressure to operate correctly.
Internal models 49 dB(A), external model 54 dB(A). Some people are susceptible to low level noise. This needs to be considered if locating an appliance near a bedroom.
