Cut and frame the hole. It is good practice to use fram- ing lumber that is the same size as the rafters. Install the frame securely because the chimney top and flash- ing anchored to the frame must be able to withstand heavy winds.
Install Remainder of Chimney Sections
Since you have already preplanned the height of your termination according to the Ten Foot Rule, continue to install pipe to the predetermined height.
Check the chimney top installation instructions for details on how high above the roof top the chimney sections (all pipes) should extend.

Installing Chimney In a Chase
Refer to Page 4, Figure 3 for an illustration of a typical chase installation.
CAUTION: Treatment of firestop spacers and con- struction of chase may vary with type of building. These instructions are not a substitute for local building codes. You must check your local building codes to determine specific requirements for your city or state. NOTE: Other building materials may be required in ad- dition to CFM Corporation Firestop Spacers.

Finish Wall
Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 12"
(305 mm) from the top of the fireplace opening. Do not install a mantel face plate less than 6" (159 mm) from top of fireplace opening. (Fig. 21) If a combus- tible material is used below a flat mantel shelf, consult your local building codes for minimum clearance from top of fireplace opening to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or deco- rative facing material meets fireplace surround must be completely sealed with a noncombustible material. (Figs. 20 and 21)
Fig. 19 Minimum clearances to combustibles.
NOTE: No side wall protection is required for fireplaces installed at 45° to two (2) side walls (corner installation).
Often a decorative surround or vertical portion of the mantel is desired. If this is constructed of any combus- tible material it must be within the safe zone indicated in Figure 22.
