Rinnai INFINITY® XR-Series (XR16-XR26)

Discontinued 2011, superseded by the Rinnai INFINITY VT-Series

Rinnai INFINITY® XR-Series (XR16-XR26)

The Rinnai INFINITY XR-Series are temperature controlled continuous flow gas hot water heaters for residential applications. Factory preset to 55 °C.

Gas continuous flow is an energy efficient heating system as it's only on when you need hot water.

The XR26a / XR26ia models in the range were designed for aggressive water areas (such as Christchurch).

Suitable for
• external residential applications (XR16-XR26)
• internal residential applications (XR26i only)
• mains and medium pressure systems

Hard or acidic water will need to be treated in order to use this product.

Gas type
Available for Natural Gas or LPG (XR26ia was only available in LPG). Gas type specified 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.

Exhaust system external units Forced flue
Flue internal units Balanced flued (room sealed appliance)
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 XR16 & XR20: NG: 0.85, 1.30, LPG: 0.70, 1.05
XR24 & XR26: NG: 1.0, 1.55, LPG: 0.70, 1.1.05
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 pressure down).
