What type of liner is required to vent a furnace into a chimney?

A suitable liner is specifically designed to meet the safety and performance requirements for venting furnaces through a chimney. This type of liner ensures that the exhaust gases produced by the furnace are effectively contained and channeled outside the building, reducing the risk of carbon monoxide buildup and other hazardous conditions.

When venting a furnace, it is critical to select a liner that can withstand high temperatures and corrosive flue gases. A suitable liner will be made of materials that are non-combustible and can resist the elements that may cause deterioration over time. This is essential for maintaining the integrity of the chimney system and ensuring that the furnace operates efficiently.

The other options, while they may imply different features or applications, do not convey the specific safety and performance standards needed for furnace venting. Therefore, understanding the importance of using a suitable liner is key to ensuring proper venting and maintaining the safety and efficiency of HVAC systems.
