Want to know what happens when you put wood into a gas log fireplace? See pics below. This damage was a result of a property management company telling a renter they could add wood to the gas log fire place. This could not be further from the truth! The flue pipe for the gas fire place is designed for the heat from the gas logs only. With the addition of the wood, additional heat load was added. This created an overheating situation that could not be vented out quick enough.
