Frequently Asked Questions - IP090S Rinnai
How to turn on the Rinnai IP090S boiler?
To turn on the boiler, ensure that the power and gas supply are open. Press the On/Off button on the control panel. The screen displays the temperature and the boiler goes into standby. Set the desired temperature using the +/- keys.
What does error code E01 on the screen mean?
Code E01 indicates an ignition fault. Check that gas is reaching (meter and valve open), that water pressure is sufficient (1-2 bar), and that the flue is not blocked. If the problem persists, contact a professional.
How to bleed the radiators of the heating circuit?
To bleed, turn off the boiler and wait for it to cool. Open the bleed valve on each radiator using a bleed key until water flows without bubbles. Then close. Check the pressure on the gauge and if necessary, add water via the filling valve.
What is the recommended water pressure for the boiler?
The ideal pressure is between 1.0 and 2.0 bar (gauge). If it drops below 1 bar, the boiler may lock out. Use the filling valve to reset the pressure to about 1.2 bar.
How to maintain the Rinnai IP090S boiler?
Annual maintenance by a professional is mandatory to ensure safety and efficiency. This includes cleaning the burner, heat exchanger, checking gas pressure, safety devices, and flue ducts.
Can propane gas be used with this model?
Yes, the IP090S boiler is compatible with propane gas (G31). However, the gas pressure must be adjusted and the injection nozzles changed if necessary. Consult an authorized installer for adaptation.
How to set the domestic hot water temperature?
Use the +/- keys on the control panel in DHW mode. The temperature can be set from 35 °C to 60 °C. To avoid burns, do not exceed 55 °C if you have children.
What to do in case of a water leak under the boiler?
Immediately shut off the cold water supply and the boiler's power supply. Place a bucket to collect the water. Contact a plumber/heating engineer to diagnose and repair the leak (seal, heat exchanger, etc.).
How to fill the boiler water circuit?
Open the filling valve (usually located at the bottom of the boiler) while monitoring the gauge. Fill until reaching 1.2 bar, then close the valve. Bleed the radiators if necessary.
Where to find spare parts for the Rinnai IP090S?
Spare parts are available from the Rinnai after-sales service or authorized dealers. Always use genuine parts to guarantee safety and warranty.
