What is the only type of venting allowed for wood burning fireplaces?

The correct type of venting for wood-burning fireplaces is Type L venting. This type of vent is specifically designed for the venting of appliances burning solid fuels, including wood. Type L vents have the appropriate construction and materials to safely handle the high temperatures and potential condensation produced during the combustion of wood.

Type L vents are typically made of stainless steel or galvanized steel and include insulation, allowing them to maintain the necessary temperature for efficient draft and reducing the risk of creosote build-up, which is a common concern with wood burning appliances.

Other types of venting like Type B and Type BH are intended for gas appliances and may not offer the same level of safety and efficiency when used with solid fuels. Super A vents are also not suitable for wood burning fireplaces, as they are specifically designed for other heating applications. This distinction is crucial for ensuring safety and compliance with building codes when installing wood-burning fireplaces.
