Installing The Chimney System - Superior TM-4500 Installation Instructions Manual

Step 5. Fireplace should be secured to side
framing members using nailing flanges. Use 8d
nails ( Figure 20 ).

Note: The nailing flange and the area directly
behind the nailing flange is exempt from the
clearances described on the fireplace clearance
label.
For Canadian Installations
Proceed with Steps 6–9
Step 6. Remove one of the knockouts from the
fireplace transition and attach the 4" (102 mm)
collar from the air kit to the transition with four
(4) No. 8 x " screws provided ( Figure 21 ).

Step 7. Connect the 4" (102 mm) Class 0 air
duct to the collar with two (2) No. 6 x " screws
provided in the hardware kit.
Step 8. Route the Class 0 air duct out the back
wall or side wall, up through the ceiling or floor
joists to an outside wall. The air duct should be
located above snow level.
Note: If the fireplace is installed against an
inside wall, the Class 0 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 nothing blocks the hood
opening. This air duct must never terminate
higher than the chimney.

Step 9. Cut or frame hole through the outside
wall for the installation of the duct inlet hood. A
4 " (114 mm) diameter hole is sufficient. Feed
the loose end of the flexible duct through the
hole cut for the inlet hood and attach to collar on
inlet hood using two (2) No. 6 x
provided. Insert hood into opening. Secure
hood in place with the No. 8 x 1
provided or with nails driven through holes in
hood flange. Seal with noncombustible water-
Nailing Tab
proof silicon type caulking. If additional duct is
needed, use Class 0 metallic duct.

INSTALLING THE CHIMNEY SYSTEM

Step 1. Check flue damper for proper opera-
tion. When the damper is in the fully closed
position, the damper control lever is pushed all
the way to the rear of the firebox. When the
damper is in the fully open position the damper
control lever is pulled all the way to the front of
the firebox.
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" (51 MM)
CHIMNEY AIR SPACE TO COMBUSTIBLE
Optional
Connection
FRAMING MEMBERS THROUGHOUT VERTI-
CAL OR OFFSET CHIMNEY INSTALLATION.
A minimum 2" (51 mm) air space must be
reserved for all combustible materials ex-
tending for any continuous length surround-
ing the chimney.
Reference Figures 18 and 19 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)
( Figure 22 ). 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 10FS-2, if
chimney penetrates ceiling vertically. If chim-
ney penetrates ceiling at 30 angle (offset chim-
ney), use 30 firestop spacer, Model 10FS30-2.
Use one nail on opposite sides to hold firestop
spacer in position. Nail permanently, using at
least two (2) more 8d nails, after chimney
sections have been assembled through the
firestop spacer and after any necessary adjust-
ments have been made. Firestop spacer must
be secured by at least four (4) 8d nails when
completely 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 23 and 24 ).
