Most Rinnai units do not require a test point. Due to the burner technology utilised in the majority of the heaters there is no requirement to conduct combustion analysis. We recommend you check the gas pressures are correct as per MFI's.

You can find out what appliance you have by looking at the data badge on the left hand side of the appliance. This begins with 'REU'.

It is recommended that the boiler should be serviced once a year.

Provide contact details or website of agents.
