10 Adjustments
When the boiler is installed it is ready for use. All adjustments of the boiler control
are already pre-programmed for a heating system with radiators/convectors with a
supply temperature of 185°F. The adjustments are described in the Parameter chapter
on page 44.
In certain cases parameters have to be altered in case of :
- Lower supply temperature
- High altitude/long vent length
Read through the Parameter chapter to adjust the boiler to its installation.
Contact Rinnai in case of doubt.
Only qualified personel who are trained for servicing these boilers are permitted
to make alterations in the controller to calibrate the boiler to the installation.
