11 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
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.
