Resumen del manual
2. Center inner slip section in inner flue pipe- slip down. 3. Center outer locking section over outer flue pipe. Push down until locking tabs are firmly engaged. 4. Pull up slightly on CTD to ensure locking joint has fi rmly engaged. Note: It is recommended that all exterior exposed metal fireplace components; such as terminations, flashings, storm collars and/or flue be painted with a premium quality, high temperature, rust preventative paint designed for metal. This is especially important when installations are made in abnormally adverse or corrosive environments; such as near lakes, oceans or in areas with consistently high humidity conditions. Consult the paint manu- facturers instructions for proper preparation and application. TEN FOOT RULE SUMMARY The minimum chimney height above the roof and/or to adjacent walls and buildings is speci- fi ed by all major building codes. If the horizontal distance from the peak of the roof is less then 10', the top of the chimney must be at least 2' above the peak of the roof. If the horizontal distance from the chimney edge to the peak of the roof is more than 10' a chimney height reference point is established on the roof surface 10' horizontally from the chimney edge. The top of the chimney must be at least 2' above this reference point. In all cases, the chimney cannot be less then 3' above the roof at the edge of the chimney. The 2' in 10' rule is necessary in the interest of safety but does not ensure smoke-free op- eration. Trees, buildings, adjoining roof lines, adverse wind conditions, etc., may require a taller chimney should the fireplace not draft properly (Figure 28). Note: If chimney extends more than 8' above roof surface, guy wires are also recommended. Use three (3) guy wires, attach to locking band assembly, extend and secure to roof in a trian- gular pattern (Figure 26). Guy wires are not supplied by the manufacturer.

CTD Termination Chimney FTF8 CHIMNEY COMPONENT CALCULATIONS The minimum installed height of the completed fireplace system is 10' 6". The maximum height is 40' 0" when the chimney is exposed. To determine the number of chimney sections and chimney components required, follow these steps: 1. Determine total vertical height of the fi replace 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 thimbles, extensions, roof fl ashing, etc. 3. The effective heights of the components are: The Fireplace = 37” FTF8-12 = 10-1/4” FTF8-18 = 16-1/4” FTF8-24 = 22-1/4” FTF8-36 = 34-1/4” FTF8-48 = 46-1/4” FTF8-CTD Termination = 6” 4 Determine amoun of chimney height required 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 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 F8FS30-2 firestop spacer as shown in Figure 29. Support the chimney at fl oor or ceiling penetration with a FTF8 stabilizer if distance of chimney below ceiling is 10' or more. Maintain 1" minimum air space to combustibles from chimney sections. The chimney must pass vertically through the attic space. Room Above F8FS30 Firestop Spacer 1" Min. Air Space 1" Min. FTF8-S4 Stabilizer Air Space 10' 30° Firestop Max. And Room Above Figure 29 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 fi replace fl ue 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 (see Figure 30). 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' (see Figure 31). 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 1/2" sheet metal screw located at the underside of the joint (see Figure 33). A 1/8" diameter hole must be drilled in the chimney joint using a 1/8” diameter drill. Hole should be drilled in center of joint overlap (see Fig...
