The closest thing we offer to meet your request is a prefabricated wood burning fireplace fitted with a gas log lighter. The lighter is essentially a length of pipe with perforations that must be lit manually with a lighter or match after the gas valve is opened. We have received several requests for an automatic style of log lighter with its own ignition system, but I have not come across a company that has gotten past the development stages. The issue is that the amount of wood ash generated would either foul or suffocate the ignitor, necessitating frequent service or replacement.
