Step 3. Note: All chimney sections are con- structed with a unique locking tabs and hem design, which ensures and immediate, tight assembly between sections. Plan your chimney requirements carefully before assembly, as the chimney is difficult to disassemble after instal- lation. If disassembled, the tabs might become damaged. Be certain that the tabs are properly formed to ensure they engage properly.

The FTF10 chimney system is a two piece chim- ney that snap locks together from the fireplace up. Always start with the inner flue section. With the lanced end up, snap lock the joint into the matching collar on top of the fireplace. At all subsequent joints, the upper flue section fits into the lower or preceding flue section. Each section snaps together by means of locking tabs (9 tabs per joint). Check each section by pulling up slightly from the top to ensure proper engage- ment before installing succeeding sections. If the flue has been installed correctly, it will not separate when tested. Also, the inner flue joint where each section is joined should be tight and flat without gaps (Figure 22 ).

The outer chimney section installs the opposite way; the lanced end goes down and each new section installs OVER the outside of the previ- ous section (Figure 23 ).

Note: Assemble one component of chimney at a time (inner section first; then outer section last) before preceding with the next complete section.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Continue to assemble the chimney up through framed opening. Assemble just enough to pen- etrate the roof flashing openings (Figure 24 ). 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.

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 12, Figure 35 ).
