“New” Type Pilot for gas logs, IPI system explained

Several years ago many of the direct vent gas logs manufactories,  in response to high natural and propane gas prices, started installing the IPI (Intermittent Pilot Ignition) systems on their products. You may have this system and not know it at first.

The IPI system is different from regular gas logs system as when you flip the switch on wall to start the logs the system goes through a start up process the starts a sparker and opens the pilot gas line. When the pilot flame is established a sensor tell the control module its OK to open main gas burner and the pilot ignites the gas and the burner if lite and you see flames and feel warmth.

All this takes less than 5 sec or so depending on how long it been sitting not running. This can take longer if the unit has sat over the summer and this is first time starting in the all.. I have seen it where you need to cycle (turn the wall switch off, wait 5 seconds, turn wall switch back on) to get the burner to go. It can take bit to get old gas out of line.

 

So how can you tell if my gas logs system is an IPI..

 

here are some photos of the gas valve 2016-01-19 11.33.27 you can see two small wires connecting to valve one is red the other is green. The red or orange one is pilot valve control and green is main burner control.

 

Another sign is you have a green or black control module some where near the gas valve with several wires plugged in it. 2016-01-19 11.33.23 Here you see the module with power from transformer in upper right of photo.. That supplies power to system to run. the transformer is plugged into to a large rectangle power port with some writing and put out 3 v AC. One thing to remember if the power goes out this system will NOT work. But have no fear, there is a backup way to make the logs run.

 

Another way to tell you have an IPI system is you have a box like this under there. the battery pack you see here 2016-01-19 11.33.30 this is designed for D cell but you can use AA as well.. (the batteries are 1.5v each so 2 batteries is 3 volts.  This is used to power the control module during a power outage. You put batteries in the case flip the wall switch and the logs should come on. Remember to remove the batteries when power comes back on. I recommend removing the transformer from the elec box under the front to remind you.

The IPI system is a good, low maintenance system that rarely give problems. Mainly we see lack of power or issue with the pilot and sensors.

They do need service every so often more for the burner and embers than the controls. We recommend every 5 yrs unless you are have issues.

Give us a call to set up an appoitntment to have your IPI, or regular system serviced for many years of problem free usage.
