Chemicals that are corrosive in nature should not be stored or used near the
boiler or vent termination.
Unsuitable heating system water can cause the formation of scale or sludge, which affects
system effi ciency. It can also cause corrosion and reduce life of the heat exchanger.
– You must follow Rinnai guidelines for boiler water quality.
– Thoroughly fl ush the system prior to fi 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 fi ll the heating system.
– Do not use inhibitors or other additives unless approved by Rinnai for that purpose.
– When freeze 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 fl oor heating systems, you
must separate the system from the boiler using plate heat exchangers.
– Valve off boiler while fl ushing system, do not introduce any system cleaner into the
boiler loop. Flush system thoroughly to remove all system cleaner before fi lling boiler.
• Noble Noburst AL
• Rhomar Hydro-Solv 9100
The system cleaners from NoBurst, Rhomar, and Fernox are not to be used in
the boiler. The boiler must be closed off (valved off) from the rest of the system
or not connected while the cleaners are in the system. The system should then
be drained and then thoroughly fl ushed with clean water to remove all the
system cleaner.
• Noble Noburst AL inhibitor
See the Rinnai Boiler Applications Manual or Chapter 6 and 9 of this manual for
additional information.
If problems occur when using sanitary water with a chlorine content
higher than 150 mg/l, no recourse can be made to the terms of the limited
warranty.
For the installation and maintenance of the boiler you will need:
– Standard tools for space heating, gas and water fi tting
– Digital manometer, capable of reading both positive and negative pressure
– Combustion analyzer (intended for use with condensing boilers)
– Digital multimeter
– pH digital meter
– Metric Allen wrenches
– Metric socket wrenches
In addition, a handtruck with a fastening belt is useful.
For maintenance of the boiler you will need, apart from standard tools for space
heating, gas and water fi ttings the following items:
- Rinnai toolkit Q and E-Series
• Sentinel X500
• Fernox Alphi 11
• Fernox F3 Cleaner
• Sentinel X400
• Sentinel X100
