Installing The Chimney System - Superior BCF-3885 Installation Instructions Manual

Step 5. 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 ( Figure 18 ).

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.

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 ( SEE **NOTE ).
A minimum 2" air space must be reserved for
all combustible materials extending for any
continuous length surrounding the chimney
( See **Note ).
**Note: 1" clearance when installing FTF8 on
38" models or FTF10 on 43" models.
Reference Figures 16 and 17 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 ceil-
ing 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) ( Figure 19 ). Then plumb from ceiling or
roof level directly above hole which has just
been completed.

Note: If Desired the optional collar duct kit,
Model FTF8-CDK or FTF10-CDK, should be
installed after the chimney has been attached to
the flue collar.
Step 3. Position appropriate firestop spacer
at ceiling and nail temporarily with two (2)
8d nails. Use flat firestop spacer, Model
F8FS-2, or F8FS30-2, if chimney penetrates
ceiling vertically ( See *Note ). If chimney
penetrates ceiling at 30 angle (offset chim-
ney), use 30 firestop spacer, Model FS30,
F8FS30 or F10FS30 ( See *Note ). Use one
nail on opposite sides to hold firestop spacer
in position. Nail permanently, using at least
two (2) more 8d nails, after chimney sec-
tions have been assembled through the
firestop spacer and after any necessary ad-
justments have been made. Firestop spacer
must be secured by at least four (4) 8d nails
when completely installed.
*Note: Use Models F8FS-2 and F8FS30-2 to
maintain 2" clearance when installing FTF8
chimney on 43" fireplaces.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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 4. Note: Chimney sections are con-
structed with a unique locking tab design,
which ensures an immediate, tight assembly
between sections. Plan your chimney require-
ments carefully before assembly as chimney
is difficult to disassemble after installation. If
disassembled, the tabs might become dam-
aged. Be certain tabs are properly formed to
ensure locking tabs engage properly.
Security Chimneys FTF8 and FTF10 chimney
systems are two piece chimneys, which snap
together from the fireplace up. Start with the
inner flue section with the lanced end up, snap
lock it in to the matching collar on top of the
fireplace. At all subsequent joints, the upper
flue section fits into the preceding flue section.
Each piece snaps together by means of locking
tabs (9 locking tabs per joint). Check each
piece by pulling up slightly from the top to
ensure proper engagement before installing
the next section. If the flue has been installed
correctly, it will not separate when you test it.
Also, the inner flue joint where each section is
joined should be tight and flat without gaps
( see Figure 22 ).
