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 efficiency. It can also cause corrosion and reduce life of the heat
exchanger.
– You must follow Rinnai guidelines for boiler water quality.
– Thoroughly flush the system prior to filling.
– Follow the Rinnai cleaning instructions.
– Never use water that has been treated by salt bedding exchangers, reverse
osmosis, D.I., or distilled water to soften the water to fill 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, Noble Noburst Aluminum, or Rhomar RhoGard Aluminum Safe Multi-
Metal.
– When using oxygen-permeable pipes, e. g. for under floor heating systems, you
must separate the system from the boiler using plate heat exchangers.
– Valve off boiler while flushing system, do not introduce any system cleaner into the
boiler loop. Flush system thoroughly to remove all system cleaner before filling
boiler.
See the Rinnai Boiler Applications Manual and chapter 10 for additional information.
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 fitting
– Digital manometer, capable of reading both positive and negative pressure
(accuracy -0.001” W.C.)
– 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 to the boiler you need, apart from standard tooling for space heating,
gas and water fitting the following items:
