Step 4. Fireplace should be secured to side
framing members using the full length nailing
tabs at the top and bottom of the fireplace front
face. Use 8d nails or equivalent (
Figure 17 ).
Figure 17
Note: The nailing tabs and the area directly
behind the nailing tabs are exempt from the
clearances described on page 5. Maintain at
least 1/2" clearance from the firebox wrapper to
the framing at the closest point of contact,
directly adjacent to the flange.
For Canadian Installations Proceed
with Steps 5 through 8
Step 5. Attach the cold climate kit, Model
FTF8-CCK1-LD, around the chimney collar with
the screws provided (
see Figure 18 ).
Note: CCK1-LD model requires a 6" diameter
Class 0 metallic air duct, acquired locally by
installer.

Step 3. Position appropriate firestop spacer at
ceiling and fasten temporarily with two (2) 8d
nails or equivalent. Use flat firestop spacer,
Model F8FS-2, if chimney penetrates ceiling
vertically. If chimney penetrates ceiling at 30
°
angle (offset chimney), use 30
°
firestop spacer,
Model F8FS30-2. Use one nail on opposite
sides to hold firestop spacer in position. Fasten
permanently, using at least two (2) more 8d
nails or equivalent, after chimney sections have
been assembled through the firestop spacer
and after any necessary adjustments have been
made. Firestop spacer must be secured by at
least four (4) 8d nails or equivalent when com-
pletely installed.
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 ).

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
extended 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
6
¹⁄₂
" (165 mm) diameter hole is required. Feed
the loose end of the flexible duct through the
hole cut for the inlet hood and attach to the
collar on inlet hood using two (2) screws. Insert
the hood into the opening. Secure in place with
nails driven through the holes in hood flange.
Seal with noncombustible waterproof silicon
type caulking. If additional air duct is needed,
use Class 0 metallic duct.
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 2" CHIMNEY
AIR SPACE TO COMBUSTIBLE FRAMING MEM-
BERS THROUGHOUT VERTICAL OR OFFSET
CHIMNEY INSTALLATION.
A minimum 2" air space must be reserved for
all combustible materials extending for any
continuous length surrounding the chimney.
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
center line, use plumb line from roof or ceiling
above fireplace to center of flue collar on fire-
place.
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.
