Step 4. Fireplace should be fastened to side framing members using the nailing tabs at the top and bottom of the fireplace front face. Use 8d nails or equivalent (Figure 17 ).

For Canadian Installations Proceed with Steps 5 through 8
Step 5. Attach the cold climate kit, Model

Step 6. Connect the 6" (152 mm) Class 0 metallic air duct to the collar on the chimney collar enclosure with the screws provided in the hardware kit.
Step 7. Route the Class 0 metallic air duct out the back wall or side wall, up through the ceiling or floor joists to an outside wall. The air duct’s inlet should be located above any anticipated snow level.
Note: If the fireplace is installed against an inside wall, the Class 0 metallic air duct may be ex- tended into a ventilated attic space at least 18" (457 mm) above the attic floor. Secure the duct hood to a vertical post with the inlet positioned downward. Ensure that nothing blocks the hood opening. This air duct must never terminate higher than the fireplace chimney.
Step 8. Cut or frame a hole through the outside wall for the installation of the duct inlet hood. A
INSTALLING THE CHIMNEY SYSTEM
Step 1. Before continuing, check the operation of the damper, as described on page 4, (refer to Figure 3 ).
Step 2. Using standard construction framing techniques, construct opening for chimney route up through the ceiling(s) and roof or through an outside chase.
Framing must maintain adequate minimum air space clearance at all times.
CAUTION: ALLOW MINIMUM 1"* CHIMNEY AIR SPACE TO COMBUSTIBLE FRAMING MEM- BERS THROUGHOUT VERTICAL OR OFFSET CHIMNEY INSTALLATION.
A minimum 1"* air space must be reserved for all combustible materials extending for any continuous length surrounding the chimney.
*Note: 2" clearance to combustibles required in Canada.
Reference Figures 15 and 16 and charts Fram- ing Dimensions for Ceiling and Roof, which specify minimum ceiling and roof dimensions.
In new construction, to determine chimney cen- ter line, use plumb line from roof or ceiling above fireplace to center of flue collar on fireplace.
For remodeling, plumb to center of flue collar from ceiling above, drive nail through ceiling from below to mark position, then mark and cut to passage from above ceiling (around nail) (see Figure 19 ). Then plumb from ceiling or roof level directly above hole which has just been completed.

Step 3. Position appropriate firestop spacer at ceiling and nail temporarily with two (2) 8d nails. Use flat firestop spacer, Model
Note: If there is a room above ceiling level, firestop spacer must be installed on the bottom side of the ceiling. If an attic is above ceiling level, firestop spacer must be installed on top side of ceiling joist (Figures 20 and 21 ).
