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uid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.

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 o󰀨 (valved o󰀨) 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 ushed with clean water to remove all the

system cleaner.

Approved inhibitors: • Rhomar Pro-tek 922 • Sentinel X100

• Noble Noburst AL inhibitor
