6.3 Underfloor heating system (plastic pipes)
When using oxygen-permeable pipes, e. g. for underfloor heating systems, the system
must be separated using plate heat exchangers.
No recourse can be made to the terms of the warranty in the event of failure
to regard the regulations pertaining to plastic underfloor heating pipes.
6.4 Gas supply connection
Only work on gas lines if you are licensed for such work.
If these instructions are not followed exactly, a fire or explosion may result
causing property damage, personal injury or death.
Rinnai wall mounted boilers are built to run on Natural Gas or Propane Gas.
The gas type the boiler is suitable for is indicated on the packaging and on
the boiler by a blue label with Natural Gas or a green label with Propane Gas
and on the identification plate on the boiler.
First check the identification plate on the boiler for the suitable gas type.
Do not use the boiler for another type of gas than indicated on the
identification plate of the boiler. This will cause improper functioning and can
damage the boiler.
Natural gas: resume with chapter 6.4.1
Propane gas: resume with chapter 6.4.2
