Product description

The United States Stove 40258 Front and Rear Liner is an essential protective component for the firebox of your wood or coal furnace. These cast iron liners are strategically placed at the front and back of the combustion chamber to shield the furnace's outer shell from the most intense direct heat of the fire. By absorbing and reflecting heat back into the firebox, they help maintain higher combustion temperatures for better efficiency while preventing the steel structure of the furnace from overheating and warping. This protection is critical for the long-term structural integrity of the appliance. Made from durable cast iron, these liners are built to endure thousands of heating cycles. Replacing damaged or missing liners is a fundamental part of furnace maintenance that ensures safe operation and maximizes the life of your heating equipment.
