Ok, I've got gas logs myself. There was a manual I could download from the model information. It told me how to service the unit and how it was supposed to work. I had a switch to the side of my bookshelf that activated the logs. There was a mechanical igniter that was used to create a spark,.I had to turn on the gas and light the pilot light. The flame sensor told the gas valve to stay open if there was a flame. The logs came on and created lots of heat, but the co detectors went off. Once the logs burned off the dust and particles, they did not set off the alarms. The logs look great and I really like having them for a heat back up. If you need some pointers call or email me.
