STR/CVR Series Woodburning Fireplaces
WARNING: DO NOT PACK REQUIRED AIR SPACES WITH INSULATION OR OTHER MATERIALS.
Mark an outline of the roof hole around the center of the point nail. NOTE: Hole dimensions given in the chim- ney top installation instructions are horizontal dimen- sions; therefore, the hole size must be marked on the roof accordingly.
Cover the opening of the installed chimney so debris cannot get into the system.
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.

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 sec- tions (all pipes) should extend.
Installing Top Housing or Termination
Follow the installation instructions provided with the chimney termination you have selected.
Installing Chimney In a Chase
Refer to Page 5, Figure 4 for an illustration of a typical chase installation.
CAUTION: Treatment of firestop spacers and construc- tion 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 addition to

Finishing
CAUTION: All joints between the finished wall and the fireplace surround (top/sides) must be sealed with non- combustible material to prevent cold air leakage into the room. Only noncombustible material may be applied to the facing of the fireplace surround. (Black painted area) (Fig. 20)
Finish Wall
Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 12" (305mm) above the front opening. Do not install a mantel face plate less than 6" (159mm) from top of fireplace opening. (Fig. 21) If a combustible mate-

rial is used below a flat mantel shelf, consult your local building codes for minimum clearance from top of fire- place opening to bottom of mantel shelf.
NOTE: No side wall protection is required for fireplaces installed at 45° to two (2) side walls (corner installation).
Adjacent combustible side walls that are within 16" (406mm) (STR33/36 and CVR36) and 20" (508mm) (STR42 and CVR42) of fireplace opening must be pro- tected with CFM Corporation Wall Shield Model SP40 or a specifically built wall shield described in Figure 20 & 24.
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 24.
