gas boiler flue temperature sensor failure


Navien boiler troubleshooting | AllBoiler

• If the impeller rotates normally, replace the flow sensor back into the boiler. • The sensor may be reused temporarily after cleaning, but replacement is recommended. Defective hot water temperature sensor: The temperature is sensed higher than the actual temperature due to a defective hot water (cold water) sensor.

Series 3 Gas-Fired Water Boilers Boiler Manual

Water temperature/ LWCO sensor The water temperature/LWCO sensor provides a signal to the control module to turn off the gas valve if the tem-perature in the boiler goes above its setting or if a low water condition is sensed. (The circulator will continue to run as long as there is a call for heat.) ⑥ Boiler …

Sure some water heaters have a flue gas spill switch that can shut down the heater. Attach a photo of the heater's draft hood and we may be able to point out the sensor and its wiring. On Kefid y Bob I just discovered an air leak from the 4" PVC exhaust pipe where it fits into the heater. Waiting on an HVAc guy to come and seal it.

Boiler - Wikipedia

The steam piping is directed through the flue gas path in the boiler furnace, an area in which the temperature is typically between 1,300 and 1,600 degrees Celsius (2,372 and 2,912 degrees Fahrenheit). Some superheaters are radiant type, which as the name suggests, they absorb heat by radiation.

Boiler Efficiency - an overview | ScienceDirect Topics

The improvement in boiler efficiency can be determined by measuring the stack flue gas temperature. The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas temperature…
