2.8.3 Water Quality Requirements
NOTE:
For additional information concerning water quality and treatment, refer to AERCO technical
documents Glycol Directive and AERCO Piping Application Guide (GF-136-P).
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.
•
Follow all guidelines for boiler water quality.
•
Thoroughly flush the system prior to filling.
•
Follow the cleaning instructions.
•
Never use water that has been treated by reverse osmosis, deionization, mineralization or
distillation to fill the heating system
•
Do not use inhibitors or other additives unless approved by AERCO for that purpose.
•
When frost protection of the heating system is desired, only use AERCO-approved antifreezes.
The allowed maximum concentration is 50%.
•
When using oxygen-permeable pipes, e. g. for under floor heating systems, you must separate
the system from the boiler using plate heat exchangers.
•
Close the valves of the boiler while flushing the system, do not introduce any system cleaner into
the boiler loop. Flush system thoroughly to remove all system cleaner before filling boiler.
Approved antifreeze (maximum concentration of 50%):
•
Sentinel X500 (available from AERCO)
•
Rhomar RhoGard Mutli-Metal (AL safe)
•
Noble Noburst AL
Approved system cleaners:
•
Sentinel X300 (available from AERCO)
•
Noble Noburst Hydronic System Cleaner
•
Fernox F3 Cleaner
•
Rhomar Hydro-Solv 9100
The system cleaners from NoBurst, Rhomar, and Fernox are NOT to be used in the boiler itself.
The boiler must be closed off (valves closed) 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 flushed with
clean water to remove all the system cleaner.
Approved inhibitors:
•
Sentinel X100 (available from AERCO)
•
Rhomar Pro-tek 922
•
Noble Noburst AL inhibitor
•
Intercool NFP-AA
•
Cryo-tek 100/Al
2.9 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
•
Manometer that is capable of reading both positive and negative pressures
•
Combustion analyzer
•
Digital multimeter
•
pH digital meter
•
Metric Allen wrenches
•
Metric socket wrenches
