10 Adjustments
When the boiler is installed the software has already been pre-programmed at the
factory. All software adjustments of the boiler control are already pre-programmed for
a heating system with radiators/convectors with a supply temperature of 176°F. The
adjustments are described in the Parameter chapter on the following page.
In certain cases parameters have to be altered in case of :
- Lower supply temperature
- High altitude/long vent length
- Minimum supply temperature
The venting / altitude calculation must always be performed during
commissioning of the boiler.
Read through the Parameter chapter to adjust the boiler to its installation.
Contact Rinnai in case of doubt.
Only qualifi ed personnel who are trained for servicing these boilers are permitted
to make alterations in the controller to calibrate the boiler to the installation.
