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

  • Combustion fan RPM check

Weights

  • A16: 13 kg

  • A20: 14 kg

  • A24/A26: 15 kg

  • A28i: 21 kg
