I bought a house with gas fireplace in it, has gas line to it but no gas log. I would like to know if I can burn wood in it. I found manuals covers in the house for a Martin Industries Model LF 36B and M36 so I have one of these models. Martin Industries is out of business so no help from them if I wanted to buy gas log but if I can I would like to burn wood. It has a 8 inch sheet metal chimney going out the roof. All information is appreciated,thanks
