Question: We recently bought a house with a huge stone fireplace (opening 54" x 45" x 30" deep), but the flue is totally inadequate. We'd like to install a wood burning stove into this space so it can be used for heat and cooking during power outages. The existing chimney is clean, inspected, solid and has a good draft. What do we need to retrofits the flue to accommodate a wood burning stove? Answer: --- You need to reline the existing chimney with an approved stainless steel liner system (6" i.d.), this will take care of the integrity of the flue, make it easier to clean and provide the proper diameter for todays hi-efficiency stoves. Depending on the construction of your fireplace, you may have to select a "rear-exit" flue stove (most cast iron stoves offer this option). Some of the models available are by Waterford (Trinity, Ashley), Vermont Castings and Dovre. For more questions contact your local hearth specialty retailer.
