2. Install the firestop spacer as required from beneath the
ceiling unless the space above is attic space. In an at-
tic, the firestop spacer should be installed at the floor
level of the attic. You must have joists or headers on
all four sides of the spacer and use a minimum of four
8-penney nails to secure the spacer.
3. To install the chimney sections, insert the male end of
the flue, the smallest diameter pipe, into the flue outlet
of the fireplace and press down until the snap locks
engage. Continue the process, adding the chimney
sections on top of each other until the chimney is at
least six inches above the roof opening on all sided. As
the chimney sections are installed, check each joint to
make sure it is properly locked to the previous section.
If additional strength of the outer pipe joints is desired,
you may use two or three sheet metal screws placed
through the area where the outer pipes overlap one
another. To install these screws, drill a 1/8-inch diame-
ter hole through the chimney sections, taking care not
to penetrate the inner flue pipe. WARNING: Be very
careful when drilling the holes into the outer pipe. The
drill must not penetrate the inner stainless steel pipe.
NOTE: If you intend to have a total fireplace installation
of more that 30 feet you must use chimney support model
11CS at or below 30 feet to support the weight of addi-
tional chimney pipe.
