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 care- fully before assembly as chimney is difficult to disassemble after installation. If disassembled, the tabs might become damaged. Be certain tabs are properly formed to ensure locking tabs engage properly.
Security's 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 into 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 (Figure 23 ).

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 24 ).

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 pene- trate the roof flashing openings (Figure 25 ).
**Note: 1" (25 mm) when installed with FTF10 in the U.S. only.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Always maintain 2" (51 mm) minimum air space to combustible materials and always check each chimney joint (inner and outer) to ensure proper engagement (See **Note). Check verti- cal alignment of chimney so that it projects from the roof in true vertical position.

Security's chimney sections do not need to be screwed together. Additional reinforcement is not necessary except in certain offset condi- tions (refer to page 14, Figure 36 ).
Step 5. The height of vertical chimney pipe supported only by the fireplace must not ex- ceed 30' (9.1 m). Chimney heights above 30' (9.1 m) must be supported by a Model
