Page 9: Important Safety Information
Use the appliance exclusively for the use for which it was designed. Rinnai boilers from the Momiji range have been designed for wall installations only. They are built for domestic or similar uses, for the production of domestic hot water and the heating of water at a temperature lower than that of boiling at atmospheric pressure. - Page 10 Hot water at 60°C can severely burn a child in less than a second. At 50°C it takes five minutes. Always test the temperature of the water before any use. To prevent these risks, Rinnai reccomends to consider setting your hot water production at a maximum temperature of 50°C.
