CHIMNEY 30° OFFSET THROUGH FLOOR

OR CEILING

It may be necessary to assemble the chimney at 30° when passing through the floor or ceiling area. Use the F8FS30 firestop spacer as shown in Figures 22 and 23. Support the chimney at floor or ceiling penetration with a FTF8 stabi- lizer if distance of chimney below ceiling is 10' or more. Maintain 1"* minimum air space to combustibles from chimney sections.

For Canada Only

When installing the chimney system through an open attic space, the attic shield assembly- firestop spacer must be used (Figure 24 ). 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 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.

The Security Chimney's 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 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 25 ).

Figure 25

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 26 ).

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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 27 ). Always maintain 1"* minimum air space to combustible materials and always check each chimney 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.

1"* Min. Air Space To Combustibles

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 38 ).

Step 5. The height of vertical chimney pipe supported only by the fireplace must not ex- ceed 30'. Chimney heights above 30' must be supported by a Model FTF8-S4 stabilizer in- stalled at 30' intervals.

Note: The Model FTF8-S4 adds 3" net effective height to the total chimney system.

Install the Model FTF8-S4 stabilizer by fitting inner section down into respective section of proceeding flue pipe and locking outer stabi- lizer section into place over the outer chimney pipe. Position for proper clearance through framed opening and nail straps securely (under tension in “shear”) into place on framing. Use 8d nails. Attach successive lengths of chimney pipe directly to stabilizer using same tech- niques as described in Step 4 (see Figure 28 ).

*Note: 2" clearance to combustibles required in Canada.
