4-Inch Firestop Radiation Shield for Selkirk Model HT

The 4-inch firestop radiation shield is used where a compatible Selkirk 4-inch insulated chimney passes through certain floor or ceiling assemblies. Selkirk identifies this component as HT4FRS.

Current Selkirk literature specifies that the firestop radiation shield is used in floor and ceiling penetrations other than those that include a ceiling support. Selkirk also notes that it is not required when passing through the roof.

When to Use a Firestop Radiation Shield

The correct penetration component depends on how the chimney passes through the structure. A supported ceiling may use a listed ceiling support, while other floor or ceiling penetrations may require the firestop radiation shield.

Do not choose between these components based only on appearance. Follow the chimney manufacturer's installation diagrams and use the part specified for your exact framing and penetration type.

Installation Notes

Maintain the airspace and framing clearances required by the Selkirk chimney system. Do not fill the required chimney clearance with insulation, wood trim, or other combustible material.

The firestop radiation shield is not a substitute for a roof flashing, storm collar, ceiling support, attic insulation shield, or other component required elsewhere in the chimney system. Follow the current Selkirk instructions for the specific penetration and structure.
