Chemicals that are corrosive in nature should not be stored or used near the
boiler or vent termination.
1.5 Boiler System Water Requirements
Unsuitable heating system water can cause the formation of scale or sludge, which aff ects
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, deionized, 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.
Approved antifreeze:
• Rhomar RhoGard Mutli-Metal (AL safe)
• Sentinel X500
(max. concentration 50%) • Noble Noburst AL
• Fernox Alphi 11
Approved system cleaner:
• Noble Noburst Hydronic System Cleaner
• Fernox F3 Cleaner
• Rhomar Hydro-Solv 9100
• Sentinel X400
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.
Approved inhibitors:
• Rhomar Pro-tek 922
• Sentinel X100
• Noble Noburst AL inhibitor
See Chapter 6 and 9 of this manual for additional information.
If problems occur when using potable water with a chloride content
higher than 150 mg/l, no recourse can be made to the terms of the limited
warranty.
1.6 Tools, materials and additional equipment
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 capable of reading micro-amps
– pH digital meter or test strips
– 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:
- Boiler toolkit
