Pipe sec-tions must be assembled independently aschimney is installed. When connecting chim-ney directly to fireplace, inner flue pipe sec-tion must be installed first with lanced sideup. Outer pipe section can then be installedover flue pipe section with hemmed end up.Press down on each pipe section until lancessecurely engage hem on fireplace starter.Wire will assure proper spacing betweeninner and outer pipe sections.Note: For Canada, use chimney parts des-ignated HT.Opening in collar aroundchimney at top of fireplace mustnot be obstructed. Never useblown insulation to fill chimneyenclosure.Continue to assemble chimney sections asoutlined, making sure that both inner andouter pipe sections are locked together. Wheninstalling double wall snap-lock chimney to-gether, it is important to assure joint betweenchimney sections is locked. Check by pullingchimney upward after locking. Chimney willnot come apart if properly locked. It is notnecessary to add screws to keep chimney to-gether (exception - see Figure 11, page 9).USING ELBOW OFFSETS (30E-8DM)1. To achieve desired offset, you may installcombinations of 12", 18", 24", 36" and48" length of double wall pipe (see offsetchart, page 7, and Figure 9).Note: For systems with 2 elbow sets, mini-mum height is 22 feet. Maximum heightfor any system is 50 feet.2. Chimney weight above offset rests onreturn elbow. Straps must be securelynailed to rafters or joists (see Figure 10,details A and B, page 9).3. Maximum length of pipe between supports(return elbow or 12S-8DM) is 6' of anglerun. Maximum of two 6' angle run sectionsper chimney system (see Figure 9).4. All pipe connections between offset andreturn must be secured with two screwson outer pipe only (see Figure 11, page9). Do not penetrate inner stainless.
