ignite gas released to pilot assembly. 2—Sensor rod acknowledges pilot flame is present before releasing gas to the main burner for ignition. When a pilot flame engulfs the sensor rod it conducts electrical current from the sensor through the flame to ground in one direction, which acts as a switch to the control module at this connection.

Nov 12, 2014· If your pilot looks like this on page 15, it is an IPI (intermittent pilot ignition) and one metal rod is the sparker and the second is the flame sensor. Once the flame is established it quits sparking and if sensor is clean a small current travels through the sensor to the valve and keeps pilot on and also allows burner valve to open.

Troubleshooting an Electronic Ignition Furnace That …

Jan 12, 2007· Troubleshooting an Intermittent Pilot (IP) Typically found in induced draft furnaces, an intermittent pilot ignites the burner gas with a highvoltage spark only when the thermostat calls for heat. Once the pilot is lit, and the main burner senses the pilot flame (using a flame sensing rod), the main burner ignites.

Flame Sensing The Basics HVAC School

Nov 27, 2019· Flame sensing rods, also known as flame rectifier rods or flame rectification rods, are commonplace in modern hot surface and ISI (intermittent spark ignition) gasfired appliances. Flame sensing rods stick out into the flame and connect back to the furnace board. Once the board sends a call to the gas valve to open, it monitors the current ...

Adjust Pilot Flame The pilot flame should envelop 1/4 to 1/2 in. (6 to 13 mm) of the sensor tip. See Fig. 4. To adjust pilot flame: 1. Turn off the system by setting thermostat below the temperature to call for heat. 2. Disconnect lead to the MV terminal on the gas control. 3. Light the pilot by setting the thermostat to call for heat. 4.

Step 9. Check that the pilot flame makes good contact with the pilot burner flame rod and check for good electrical connections through the pilot tubing if you have the main valve open and the main burner doesn''t light. Cycle the thermostat off and back on. The main burner should light. If it doesn''t, replace the SmartValve.
