1.5 Followtheseinstructionsforthespaceheatingwater
Unsuitable heating system water can cause the formation of scale or sludge, which
affects system efciency. It can also cause corrosion and reduce life of the heat
exchanger.
– You must follow Rinnai guidelines for boiler water quality.
– Thoroughly ush the system prior to lling.
– Follow the Rinnai cleaning instructions.
– Never use water that has been treated by a reverse osmosis, D.I., or distilled water
to soften the water to ll the heating system.
– Do not use inhibitors or other additives unless approved by Rinnai for that purpose!
– When frost protection of the heating system is desired, only use Rinnai-approved
antifreezes. The allowed maximum concentration is 50%.
– When using oxygen-permeable pipes, e. g. for under oor heating systems, you
must separate the system from the boiler using plate heat exchangers.
– Valve off boiler while ushing system, do not introduce any system cleaner into the
boiler loop. Flush system thoroughly to remove all system cleaner before lling boiler.
