Rinnai’s most efficient continuous flow gas hot water system. Rinnai INFINITY EF condensing continuous flow gas water heaters effectively capture waste heat from the flue gas through the use of a secondary heat exchanger to help heat the water with less energy.
Rinnai’s most efficient continuous flow gas hot water system. Rinnai INFINITY EF condensing continuous flow gas water heaters effectively capture waste heat from the flue gas through the use of a secondary heat exchanger to help heat the water with less energy.
Hot water capacity 1.5 to 37 litres per minute
Suitable for • Commercial and domestic internal applications
• Mains and medium pressure systems
• Solar installations as a gas boost
Hard or acidic water will need to be treated in order to use this product.
Gas type Available for Natural Gas or LPG. Specify gas type at time of purchase.
Positioning internal units
All continuous flow water heaters must be installed to ensure access can be gained, for servicing and repair, without hazard or undue difficulty. Sufficient clearances shall allow access and removal of all serviceable components.
For internal units we recommend a 600 mm clearance for servicing access. This can be reduced to 50 mm if installed in a cupboard.
REU number:
REU-KM3237FFUD-ZK
Factory preset temperature:
55 °C
Rinnai product code:
INFEF250FFN/INFEF250FFL
Capacity
Hot water capacity: 1.5-37 litres per minute
Nominal water capacity: 32 litres per minute at a 25 ° rise (1920 L/h)
Connections
Hot water outlet: R¾ (20 mm)
Cold water inlet: R¾ (20 mm)
Gas supply: R¾ (20 mm)
Condensate: R½ (15 mm)
Exhaust system
Forced flue (balanced flued, room sealed fan assisted appliance). Flue dimensions; inner – 80 mm, outer 125 mm
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 size
NG: 1.15, 1.9, 1.8*
LPG: 0.75, 1.15, 1.1*
* only one point
Line pressure (min.)
NG: 1.13 kPa, 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 line pressure down.
Power consumption
Normal: LPG – 92 W, NG – 72 W
Automatic frost protection: 218 W
Standby: 2.4 W
