Empire 30 Inch Super Sassafras Refractory Vent Free Gas Log Set for Slope Glaze Burners

Regarding your Marco B-Vent Fireplace Model # 794091, unfortunately, Marco has been out of business for some time, and their parts, including log sets, are discontinued and no longer available through any manufacturer channels. We cannot provide replacement parts for obsolete brands like Marco due to safety concerns and the inability to ensure compatibility. The only logs safely approved for that unit will be the ones listed in the Marco manual. It should list the specific model number, and your best bet might be a Google search for distributors with overstock or trying a local fireplace shop. We would be happy to explore other replacement options if you decide to go that route.
