Reduce the value if the water heater activates during the purge cycle
TROUBLESHOOTING:
Insufficient or no heat:
•
Check filter, replace if dirty
•
Verify the hydronic coil is not clogged.
•
Verify there no air trapped in the heating loop. Purge the loop if air is present.
•
Verify Rinnai Engine operation and water temperature. Clean inlet water filter on Rinnai engine.
•
Verify there are no restrictions in the heating loop. Verify all valves are fully open and functional.
The pump does not run:
•
Verify 120V power is present to the pump
•
Hard water may cause the pump to seize. Recirculation mode will prevent pump seizing.
The pump is noisy at start-up:
•
Purge the hot water loop of air.
Heating during the fan on mode:
•
Verify the check valve in the heating circuit is present and is not stuck.
