Rinnai I-Series Condensing Boiler Solo Manual

IMPORTANT

 On inial startup of the system, it is necessary to put the boiler into a deaeraon process to

remove all air from the system piping and boiler. Failure to properly deaerate the boiler

and system may result in damage to the boiler, which is not covered by the boiler

warranty.

 It can take up to a week before all the air has disappeared from a newly-lled and

pressurized installaon. During the rst week of operaon, noises can be heard which

indicate the presence of air. The automac air vent in the boiler and air separator in the

heang system will remove the air, which means the water pressure will reduce some

during this period; therefore, addional water is necessary to maintain proper pressure in

the heang system. Water pressure needed for operaon:

 The boiler is in normal operaon between 17 - 26 PSI (1.2 - 1.8 bar).

 Below 7 PSI (0.5 bar), the boiler will have an error code (E430 diagnosc code will be

present on the controller display) and will not operate. Increasing the heang system

water pressure is necessary for operaon.

 Between 7 - 13 PSI (0.5 - 0.9 bar), operaon will be limited (E430 diagnosc code will

be present on the controller display).

 The maximum pressure permied inside the heat exchanger is 45 PSI (3.0 bar).

 The pressure relief valve supplied with the boiler is rated to 30 PSI (2.1 bar).
