Hot water capacity
2.4 to 37 litres per minute.
• Commercial and domestic external applications
• Applications requiring higher hot water temperatures, can be set up to 95 °C
• Mains and low pressure systems
• Solar installations as a gas boost
Hard or acidic water will need to be treated in order to use this product.
Available for Natural Gas or LPG. Specify gas type at time of purchase.
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.
|Factory preset temperature:||55 °C|
|Rinnai product code:||INFHD250HNCN/ INFHD250HNCL|
|Capacity||Hot water capacity: 2.4 to 37 litres per minute
Nominal water capacity: 32 litres per minute at a 25 °C rise (1920 L/h)
|Connections||Hot water oulet: R¾ (20 mm)
Cold water inlet: R¾ (20 mm)
Gas supply: R¾ (20 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 (mm)||NG: 1.00, 1.65 LPG: 0.75, 1.15|
