To Next PageTo Next PageWhy does my Patterson-Kelley MACH Boiler show error E12 due to low gas pressure?
If your Patterson-Kelley Boiler experiences low gas pressure because a gas-supply shut-off valve was closed, the E 12 error will appear on the display panel, locking out the boiler. To resolve this, manually reset the low gas pressure switch and then press the front panel reset button once the gas pressure is restored.
What to do if my Patterson-Kelley MACH is locked out due to high gas pressure?
If your Patterson-Kelley Boiler experiences high gas pressure, E 12 will remain on the display with the boiler locked out. To fix this, reset the high gas pressure switch and then press the front display panel reset button once proper gas pressure is restored.
How to reset a Patterson-Kelley MACH Boiler after a high water temperature lockout?
If your Patterson-Kelley Boiler's water temperature exceeds the high-limit, the boiler will lock out. To resolve this, manually reset the switch and press the front panel reset button once the water temperature falls below the high-limit temperature.
What to do if my Patterson-Kelley Boiler indicates a 'Low Air' issue?
If your Patterson-Kelley Boiler is showing a low air issue, verify that the burner is clean and inspect the intake and exhaust ducts for any obstructions to airflow. Refer to Section 5.2, "Cleaning the Burner."
How to recover Patterson-Kelley MACH after loss of water level?
When the correct water level is re-established in your Patterson-Kelley Boiler, pushing the reset button will return the sequence to Step 5, provided that the other limits are satisfied.
What happens after a flame failure in a Patterson-Kelley MACH Boiler?
If the Patterson-Kelley Boiler experiences flame failure, the 3 second trial-for-ignition begins again after the spark ignition is re-energized.
