If you live in Maine and had a propane stove or fireplace installed by Woodman's it was most likely installed by an unlicensed person. Contact the Maine Fuel Board and they will check for you. If you live in New Hampshire and had a propane stove or fireplace installed by them at least one of the installers was likely not licensed. Contact the NH Fire Marshall's Office to check. Propane can be an explosive gas and it produces carbon monoxide when it burns. BE SAFE! Call the appropriate agency to make sure your installation is safe to operate. Your life could depend on it...
