Lucent Technologies TM-4500 For Canada Only, Roof Pitch Model Flat to 6/12, 12 to 12/12

For Canada Only

When installing the chimney system through an open attic space, the attic shield assembly- firestop spacer must be used (Figure 23 ). This installation procedure is Warnock Hersey Inc. listed only for use in Canada.

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 Chimneys FTF10 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 24 ).

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 25 ).

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 26 ). 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 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 FTF10-S4 stabilizer in- stalled at 30' intervals.

Note: The Model FTF10-S4 adds 3" net effective height to the total chimney system.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Install the Model FTF10-S4 stabilizer by fitting inner section down into respective section of proceeding flue pipe and locking outer stabilizer section into place over the outer chimney pipe. Position for proper clearance through framed opening and fasten straps securely (under ten- sion in “shear”) into place on framing. Use 8d nails or equivalent. Attach successive lengths of chimney pipe directly to stabilizer using same techniques as described in Step 4 (Figure 27 ).

Note: Do not apply excessive pressure to any subsequent chimney sections following the sta- bilizer when installing. Ensure each subsequent chimney section is securely attached by testing as noted in Step 4.

Step 6. Select the proper Security Chimneys roof flashing based on pitch of roof. Use chart below for selection:

Roof Pitch	Model
Flat to 6/12	F10F6
6/12 to 12/12	F10F12

Next, slide roof flashing over extended chimney section that previously has been installed above the roof opening in Step 4. FTF10 flashings require flashing spacers. Slide flashing all the way down until the flashing base rests flat on the roof (Figure 28 ). Again, check the vertical position of the chimney and the 2" minimum air space to combustibles.
