NOTICE: When installing in a chase, you should insu- late the chase as you would the outside walls of your home. This is especially important in cold climates. Insulation should be considered a combustible ma- terial. Maintain proper clearances to all combustible materials.

NOTICE: Treatment of firestops and construction of the chase may vary from building type to building type. These instructions are not substitutes for the requirements of local building codes. You must fol- low all local building codes.
