How to fix poor ground error on PEERLESS PureFire PF-110 Boiler?
- SSarah SmithAug 31, 2025
If your PEERLESS Boiler is showing 'POOR GROUND' error, check the boiler ground and harness.
How to fix poor ground error on PEERLESS PureFire PF-110 Boiler?
If your PEERLESS Boiler is showing 'POOR GROUND' error, check the boiler ground and harness.
What causes high stack temperature in PEERLESS Boiler?
If your PEERLESS Boiler has a 'HIGH STACK TEMPERATURE', and the flue pipe is hot, check the flue temperature and compare it to the values in Table 8.5. Also, inspect for proper gas input and combustion readings, and check for a dirty heat exchanger. If the flue pipe is not hot, check the flue sensor and harness.
How to troubleshoot a blocked vent in PEERLESS Boiler?
If you have a blocked vent in your PEERLESS Boiler, check for a blocked vent pipe or blocked heat exchanger. Also, check the switch and tubing connected to the switch.
What to do if PEERLESS PureFire PF-110 Boiler showing false flame detected?
If your PEERLESS Boiler shows a 'FALSE FLAME DETECTED' error, first verify there is no flame in the observation port, then check the sensor.
How to fix hot/neutral reversed error on PEERLESS PureFire PF-110 Boiler?
If your PEERLESS Boiler displays the error 'HOT/NEUTRAL REVERSED', verify the polarity of the incoming wiring and check the boiler ground and harness.
What to do if there is a false flame detected before ignition in my PEERLESS PureFire PF-110?
If you're experiencing a false flame detected before ignition with your PEERLESS Boiler, check the flame sensor and igniter to ensure there are no shorts to ground.
What to check if my PEERLESS PureFire PF-110 shows a low water error?
Check the boiler water level, low water cut-off, and harness. If a LWCO is not used, a jumper should be placed between terminals #9 and #10, LWCO Contact.
How do I fix a blocked condensate drain on my PEERLESS Boiler?
If your PEERLESS Boiler shows a 'BLOCKED CONDENSATE DRAIN' error, check the condensate tanks, hoses, condensate switch, and harness.
