Exhaust system
External units - forced flue
Internal unit - room sealed 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
Model A16
NG - 0.9, 1.50
LPG - 0.71, 1.09
Model A20-A26
NG - 1.08, 1.80
LPG - 0.73, 1.12
Line pressure (min.)
NG - 1.13kPa, 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.
Power consumption
Normal: 47 W (A16), 58 W (A20), 56 W (A24), 66 W (A26), 95 W (A28i)
Standby: 2 W
Automatic frost protection: 68 W (A16-A26), 120 W (A28i)
Pressure relief
Valve opens at 2060 kPa, closes at 1470 kPa
Water supply
Nominal operating pressure:
A16: 120-1000 kPa
A20: 160-1000 kPa
A24: 200-1000 kPa
A26: 200-1000 kPa
A28i: 220-1000 kPa
Minimum operating water flow: 1.5 litres per minute (depends on setpoint and inlet temp.)
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.
Noise level
External units 50 dB(A), internal unit 54 dB(A). Some people are susceptible to low level noise. This needs to be considered if locating an appliance near a bedroom.
NOx af
35 ppm (40 ppm A28i)
Safety devices
Flame failure
Boil-dry protection
Overheat protection
Fusible link
Pressure relief valve
Combustion fan RPM check
Weights
