How to troubleshoot high stack temperature in my PEERLESS PureFire PF-140?
If the flue pipe is hot, check the flue temperature and compare it to the values shown in Table 8.5. Also, check for proper gas input and combustion readings, and inspect for a dirty heat exchanger. If the flue pipe is not hot, check the flue sensor and harness.
How do I fix a blocked condensate drain on my PEERLESS PureFire PF-140 Boiler?
If your PEERLESS Boiler shows a 'BLOCKED CONDENSATE DRAIN' error, check the condensate tanks, hoses, condensate switch, and harness.
What to check if my PEERLESS PureFire PF-140 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.
What to do if there is a false flame detected before ignition in my PEERLESS Boiler?
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.
Why is the return temperature higher than the supply temperature in my PEERLESS PureFire PF-140?
Check the system piping to ensure that the water is entering the return connection and exiting the supply connection.
What to do if my PEERLESS PureFire PF-140 has a blocked condensate drain?
Check the condensate tanks, hoses, condensate switch, and harness.
How to troubleshoot stack sensor short error on PEERLESS PureFire PF-140 Boiler?
If your PEERLESS Boiler displays the error 'STACK SENSOR SHORT', check the harness and sensor.
How to fix DHW sensor short error on PEERLESS Boiler?
If your PEERLESS Boiler displays the error 'DHW SENSOR SHORT', check the harness and sensor.
How to troubleshoot high return temp on PEERLESS Boiler?
If your PEERLESS Boiler displays 'HIGH RETURN TEMP', check for reversed supply and return piping or a pump installed backwards.
Why is the return higher than supply on my PEERLESS Boiler?
If you see 'RETURN HIGHER THAN SUPPLY' on your PEERLESS Boiler, check the system piping to ensure water enters the return connection and exits the supply connection correctly. Also, compare the supply thermistor reading to the temperature gauge; if they don’t match, replace the supply thermistor.
