Hot water capacity 1.5 to 37 litres per minute
Suitable for • Commercial and domestic external 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.
Clearances The following diagram has been provided to assist you in determining where (and if) an external continuous flow water heater can be positioned. If in doubt, prior to purchase, consult a licensed gasfitter.
Clearance below eaves, balconies, and other projections, for all models is 300 mm.
* Rinnai recommend 1.5 m to give enough clearance for the pipe work, and to safely expel flue gases.
REU number:
REU-KM3237WD
Factory preset temperature:
55 °C
Rinnai product code:
INFEF250N/INFEF250L
Capacity
Hot water capacity: 1.5-37 litres per minute
Nominal water capacity: 32 litres per minute at a 25 °C 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
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 – 62 W, NG – 51 W
Automatic frost protection: 170 W
Standby: 2.4 W
