Nominal operation pressure is 1-7 bar and it uses a 230V AC 50Hz 1ph power supply with an electrical consumption of 68W. Meanwhile, where an external installation is required, the Rinnai Infinity 17e external continuous flow water heater offers greater flexibility at the design stage and delivers a viable solution where flue runs are problematic or internal space is not available. Capable of flow rates reaching 510 litres per hour at a 50°C rise, the 17e is suitable for multiple applications and can be specified for use with Natural Gas or propane. The 17e has full frost protection and is available with a range of external ancillary items, including pipe cover box – and security cage where necessary. The Infinity 11i interior unit differs from the 17i as it weighs 2kg less at 16kg and consumes 6.10kW - 21.60kW of Natural Gas. Under the ACOP L8 (Legionella guidelines), continuous flow water heaters are favoured as the units are normally positioned close to the outlets, in restaurants for example, where the system turnover is frequent and store volumes are small meaning legionella risk is minimal. All three models are available ex- stock in either natural gas or LPG. For more details on RINNAI products visit www.rinnaiuk.com 75
