If the water pressure switch on your PEERLESS Boiler is open, ensure the system pressure exceeds 10 psig. Also, check for leaks in the system piping. To check the switch operation, apply a jumper. Replace the switch if it's not functioning correctly.
How to fix a high limit exceeded error on a PEERLESS Gas?
If the high limit has been exceeded on your PEERLESS Boiler, first check the circulation pump operation. Then, ensure adequate flow through the boiler by checking the status menu, making sure there's less than a 50°F rise from the return thermistor to the supply thermistor. Finally, replace the switch if it's faulty.
What to do if the blocked vent pressure switch is open in my PEERLESS Gas?
If the blocked vent pressure switch is open on your PEERLESS Boiler, make sure that the vent is not blocked. Check the switch operation by applying a jumper. Replace the switch if it is not functioning properly.
Why is the combustion fan speed high on my PEERLESS Boiler?
If the combustion fan speed is too high on your PEERLESS Boiler, begin by checking the combustion air fan wiring. If the wiring is correct, consider replacing the combustion air fan. If problems persist, the control board may need replacement.
Why is the combustion fan speed low on my PEERLESS Gas Boiler?
If the combustion fan speed is low on your PEERLESS Boiler, first check the combustion air fan wiring. If the wiring is correct, consider replacing the combustion air fan. If problems persist, the control board may need replacement.
