1. Check the distance between the electrode and thermocouple; a 3 – 4 mm distance is best. When the knob clicks, you should see a spark between the two points.
2. If you do not pause when rotating the knob, it will be difficult to ignite, as the fuel must fill the gas line running from the valve in the front - to the burner in the back.
3. Ensure that all other burners are turned off first. If the valves of the main burner are open but the burners are not lit, the rear IR burner will not ignite.
4. You may need to attempt lighting the IR burner a couple of times if this is the initial time using the grill or if the grill has not been on for an extended period.
