Why can't I find the analyser test point?
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.

Why is the appliance making banging and clattering noises?
This could be a result of Lime scale build up or incorrect burner pressures set. Check gas pressures as per MFI's, remove heat exchanger thermistor and look for scale deposits. If scale present, flush heat exchanger for 24 hour period with a light acidic solution like white vinegar.
