Anleitung Zusammenfassung
Determine total vertical height of the fireplace installation. This dimension is the distance from the surface the fireplace sets on to the point where smoke exits from the termination. 2. Determine the number of chimney components required, except chimney sections. This would include firestop spacers, stabilizers, roof flashing, etc. 3. The effective heights of the components are: The Fireplace = 43 ..." FTF8-12 = 10 ..." FTF8-18 = 16 ..." FTF8-36 = 34 ..." FTF8-48 = 46 ..." FTF8-CTD Termination = 4" FTF8-CT1 Termination = 12" to 18" FTF8-CT2 Termination = 15" to 23" FTF8-CTDT Termination = 12" to 18" FTF8-CTT Termination = 6" to 14" FTF8-ATT Termination = 8" to 14" FTF8-S4 Stabilizer * = 3"* * Required for every 30' of vertical chimney and/or 10' of offset chimney. 4.4.quired by subtracting total combined height of all pre-selected components (fireplace and chimney components from total desired height.) Reference Vertical Elevation Chart and determine the number of chimney sections (quantity and length) required. SPECIAL OFFSET INSTRUCTIONS To clear any overhead obstructions, you may offset your chimney system using Security's 30° offset and return elbows. Use two elbows an offset elbow to initiate the offset and a return elbow to terminate it. A 30° offset elbow, angling in any direction, may be the first component used off the top of the fireplace flue collar. The offset and return elbows may be attached together, or a section or sections of chimney may be used between, but do not exceed 20' in total length between elbows. If sections of pipe exceed 10' between elbows, a chimney stabilizer must be used at the midpoint (Figure 37). The stabilizer support straps must be attached under tension (in shear) to structural framing members above. When two sets of elbows are used, the maximum combined length of chimney used between elbows cannot exceed 20' (Figure 38). Example: If C1 = 10' then C2 cannot exceed 10'. If an offset exceeds 6' in length, each chimney joint beyond the first 6' of offset to the return elbow, must be secured by a No. 8 x ..." sheet metal screw located at the underside of the joint (Figure 39). A ..." diameter hole must be drilled in the chimney joint using a ..." diameter drill. Hole should be drilled in center of joint overlap (Figure 40). Be sure to drill only through the outer chimney casting. Do not puncture the inner flue. Maximum offset of chimney system is 30°. Two offsets must not be assembled to form a 60° offset. However, two sets of offset and return elbows may be used on a single flue system, provided the total height of the system exceeds 25'. Return elbow support straps must be securely attached under tension (in shear) to structural framing members above. Do not substitute a FTF8-30 offset elbow in place of a FTF8-E30 return elbow. OFFSET CALCULATIONS Step 1. Use Offset Chart to determine amount of horizontal offset (A) and height (B) for various chimney section assemblies. FTF8 VERTICAL E2. Use “Height of Chimney Only” column e Vertical Elevation Chart to determine combinations of chimney used above return elbow to achieve desired heights. Reference Components Effective Height Chart in vertical elevation chart section. Step in ThLEVATION CHART Step 3. Use Elevation Chart as job estionly. Add necessary firestop spacers and lizers as required. Firestop spacers muused as shown in Figures 23 and 24and lizers as shown in Figure 29. mator stabist be stabi- Height Of Chimney Only Number Of FTF8 Chimney Lengths Height Of Chimney Only Number Of FTF8 Chimney Lengths Inches Feet/Inches 12" 18" 36" 48" Inches Feet/Inches 12" 18" 36" 48" 11 17 21 ... 27 ... 0 11 1 5 1 9 ... 2 3 ... 1 0 2 1 0 1 0 1 0 0 0 0 0 0 0 0 386 ... 390 ... 396 ... 404 ... 32 2 ... 32 6 ... 33 0 ... 33 8 ... 0 2 1 0 1 0 1 0 0 0 0 1 8 8 8 8 35 47 51 ... 57 ... 2 11 3 11 4 3 ... 4 9 ... 0 0 0 1 0 0 1 0 1 0 1 0 0 1 0 1 414 ... 416 ... 420 ... 426 ... 34 6 ... 34 8 ... 35 0 ... 35 6 ... 1 0 0 1 0 0 1 0 1 0 1 0 8 9 8 9 63 ... 67 ... 73 ... 81 ... 5 3 ... 5 7 ... 6 1 ... 6 9 ... 0 2 1 0 1 0 1 0 0 0 0 1 1 1 1 1 432 ... 437 443 450 ... 36 0 ... 36 5 36 11 37 6 ... 0 2 1 0 1 0 1 0 0 0 0 1 9 9 9 9 93 ... 97 ... 102 ... 109 ... 7 9 ... 8 1 ... 8 6 ... 9 1 ... 0 0 1 0 0 1 0 1 0 1 0 0 2 1 2 2 461 462 ... 466 ... 472 38 5 38 6 ... 38 10 ... ... 39 4... 1 0 0 1 0 0 1 0 1 0 1 0 9 10 9 10 113 ... 119 ... 127 ... 137 ... 9 5 ... 911 ... 10 7 ... 11 5 ... 2 1 0 1 0 1 0 0 0 0 1 1 2 2 2 2 478 ... 483 489 496 ... 39 10 ... 40 3 40 9 41 4 ... 0 2 1 0 1 0 1 0 0 0 0 1 10 10 10 10 139 ... 143 ... 149 ... 155 ... 11 7 ... 11 11 ... 12 5 ... 12 11 ... 0 0 1 0 0 1 0 1 0 1 0 0 3 2 3 3 507 508 ... 513 519 42 3 42 4 ... 42 9 43 3 1 0 0 1 0 0 1 0 1 0 1 0 10 11 10 11 159 ... 165 ... 173 ... 183 ... 185 ... 189 ... 195 ... 13 3 ... 13 9 ... 14 5 ... 15 3 ... 15 5 ... 15 9 ... 16 3 ... 2 1 0 1 0 0 1 0 1 0 0 0 1 0 0 0 1 1 0 1 0 3 3 3 3 4 3 4 525 529 ... 535 ... 543 553 ... 555 559 ... 43 9 44 1 ... 44 7 ... 45 3 46 1 ... 46 3 46 7 ... 0 2 1 0 1 0 0...
