Wall Thimbles and Firestops

When installing a venting system it is essential that clearance to combustibles is met. Installation instructions of the appliance or venting system will determine the specific requirements. When passing through a wall or a floor a firestop and wall thimble will assure the proper clearances are met. Only use thimbles and firestops that are listed for the system you are installing.
