Pull out the inner part (Ø 4 in.) from bothflexible sections and apply a generous bead of latex-basedsealant inside one of the sections. Then assemble the 4 in.connecting tube with the 4 in. flexible pipe. Sections mustoverlap over more than 2 in. Fasten using three self-drillingscrews. Repeat operation to assemble the other 4 in.section to the 4 in. connecting tube. This procedure alsoapplies to 7 in. sections.The use of flexible pipes requires the use of supports every3 ft. (1 m). These supports can also be used with hard exhaust pipes when necessary.3.2.4.2 HARD VENT SECTION ASSEMBLY• Apply a generous bead high-temperature latex-based sealant inside the female part of each section as shownin figures 3.2.4.2.a and 3.2.4.2.b.• Connect the two sections and have them overlap on at least 1.5 in. (3.8 cm).• Fasten both sections together with three self-drilling screws as shown in figure 3.2.4.2.c.Figure 3.2.4.1.aFigure 3.2.4.2.aFigure 3.2.4.2.dFigure 3.2.3.8.dFigure 3.2.3.8.eFigure 3.2.4.2.b |
