They use an AA battery for spark- this is a good option if A/C power cannot be obtained at the fire pit site.

The FPPK inserts are perfect if flame sensing safety is desired, and there is no power available to the fire pit site. The FPPK system also uses a spark generator, so no match lighting is required, and your flame height is adjustable with the use of a manual knob.

Once power is applied to the unit (120vac or 24vac), the system will allow gas to flow to the pilot assembly- the hot wire igniter will glow igniting the gas. The thermocouple on the pilot assembly will sense this pilot flame and safely open the valve to the main burner- the pilot flame then ignites the main burner. If at any time the pilot flame is lost, the unit will turn off the gas for safety, and then automatically restart.
