d. Dip Switches:
- Why eliminate dip switches? Dip switches are very small creating a possibility of mistakes
when selecting a switch. For this reason, Rinnai decided to move to the parameter settings
method. This procedure allows you to confirm your settings with the controller’s display.
e. Gas Valve:
- Why use a zero governor gas valve? Rinnai switched to this valve system in order to satisfy
the PVC 2” air/exhaust venting requirement. The current proportional gas valve would
not provide the air-fuel ratio with respect to the air quantity to accomplish this task.
- This system eliminates having to set operational gas pressures.
- Maintain good combustion under blocked flue conditions and low gas pressure.
- Will dramatically reduce code 11.
