9.2 Filling the heating system

Freeze protection
Freeze protection for new or existing systems must use glycol that is specially
formulated for this purpose. This includes inhibitors, which prevent the glycol from
attack the metallic components. This should be for multi-metallic components.
Make certain to check that the system fluid is correct for the glycol concentration and
inhibitor level. The system should be tested at least once a year and as recommended
by the producer of the glycol solution. The allowed maximum concentration is 50%.
Use only Rinnai approved inhibitors. See below for an approved list of inhibitors.
Use only inhibited propylene glycol solutions, which are specially formulated
for central heating systems. Ethylene glycol is toxic and can attack gaskets
and seals used in the boiler and system. Approved glycols are listed below.
Additives in the installation water are not permitted.
• 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 flushed with clean water to remove all the
system cleaner.
