Specication
Designed and made in Japan, the Rinnai INFINITY EF26 and A-Series are continuous ow
gas hot water heaters with inbuilt frost protection. The EF26 is a condensing model. They have
electronic ignition and require electricity to operate. They are factory preset to 55 °C (maximum set
temperature is 65 °C).
Scope of use
Suitable for residential applications only. They are designed to be externally mounted on an
outside wall and located as close as practicable to the most frequently used hot water outlet(s), to
reduce the delay for hot water delivery.
They are not suitable as a spa or swimming pool heater, and for hydronic heating. They are also
not suitable as a gas boost for solar installations as the temperature cannot be set high enough.
Hard or acidic water will need to be treated to use this product.

• Boil-dry protection
• Overheat protection (OHS)
• Fusible link
• Pressure relief valve
• Combustion fan rpm check
Line pressures
• NG 1.13-3.0 kPa
• LPG 2.75-3.0 kPa
The maximum line pressure is 3.5 kPa, with the maximum standing pressure under abnormal
intermittent conditions 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.
