Wire will assure proper spacing between
innerandouterpipesections.
Note: For Canada, use chimney parts des-
ignated HT.
Opening in collar around
chimney at top of replace must
not be obstructed. Never use
blown insulation to ll chimney
enclosure.
Continue to assemble chimney sections as

combinations of 12", 18", 24", 36" and
48"lengthofdoublewallpipe(seeoffset
chart,page7,andFigure9).
Note: For systems with 2 elbow sets, mini-
mum height is 22 feet. Maximum height
for any system is 50 feet.
