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 21 and 22 ).

For Canada Only
When installing the chimney system through an open attic space, the attic shield assembly- firestop spacer must be used (Figure 25 ). This installation is required only for use in Canada.

Note: For Canadian installations, all chimney installedoutsidethebuildingmustbeconstructed with galvalume (outer sections only) effective January 1, 1992. The appropriate model desig- nations are located in the back of this manual.
Step 4. Note: Chimney sections are constructed with a unique locking tab design, which en- sures an immediate, tight assembly between sections. Plan your chimney requirements carefully before assembly as chimney is diffi- cult to disassemble after installation. If disas- sembled, the tabs might become damaged. Be certain tabs are properly formed to ensure locking tabs engage properly.
The Security FTF8 chimney system is a two piece chimney, 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 fire- place. At all subsequent joints, the upper flue section fits into the preceding flue sec- tion. 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.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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 (Figure 26 ).
Figure 26
Outer pipe section installs in just the opposite way; the lanced end goes down and each new section goes OVER the outside of the previous section installed (Figure 27 ).
Locking Tabs (Lances)

Note: Assemble one component of chimney at a time (inner section first, then outer section last) before proceeding with the next complete section.
Continue to assemble the chimney up through framed opening. Assemble just enough to pen- etrate the roof flashing openings (Figure 28 ). Always maintain 2" minimum air space to com- bustible materials and always check each chim- ney joint (inner and outer) to ensure proper engagement. Check vertical alignment of chim- ney so that it projects from the roof in true vertical position.
