ODYSSEY SERIES FIREPLACE WITH GAS LOG SET
Æ
WARNING! RISK OF FIRE.
8. Double-check the Chimney Assembly
Continue assembling the chimney sections up through
the firestop spacers as needed. While doing so, be aware
of the height and unsupported chimney length limitations
that are given on page 12 under “Chimney Requirements”.
Check each section by pulling up slightly from the top to
ensure proper engagement before installing the
succeeding sections. If they have been connected
correctly, they will not disengage when tested.
9. Secure the Chimney System
When offsets and returns are joined to straight pipe
sections, they must be locked into position with the
screws provided, using the predrilled holes. To prevent
gravity from pulling the chimney sections apart the returns
and the chimney stabilizers have straps for securing
these parts to joists or rafters. See Figure 15.
Note:
Be sure to provide support for the pipe during
construction and check to be sure inadvertent loading
has not dislodged the chimney section from the fire-
place or at any chimney joint.

WARNING!
10. Mark the Exit Point of the Roof
Locate the point where the chimney will exit the roof by
plumbing down to the center of the chimney. Drive a nail
up through the roof to mark the center. See Figure 16.
11. Cut out the Hole in the Roof
Measure to either side of the nail and mark the 14-1/2” x
14-1/2” opening required. This is measured on the
horizontal; actual length may be larger depending on the
pitch of the roof. Cut out and frame the opening. See
details.
12. Assemble the Chimney Sections
Continue to add chimney sections through the roof
opening, maintaining at least a 2” air space.
