offset installation Sequence

1. Determine the location and amount of offset required, then select the combinations of chimney sections

and elbows required from the offset chart. Refer to Page 15.

2. Install the first elbow by placing the extended flue into the mating part of the fireplace or chimney sec-

tion. Push down until the outside or inlet air duct of the elbow overlaps and the snaps lock the elbow
into the fireplace or chimney section.

3. Nail the support straps to the framing member with a minimum of two 8-penny nails per strap.
4. Install the sections of pipe between elbows until the proper number of chimney sections have been in-

stalled.

5. Install the second elbow to return the run of the chimney to vertical.
6. Nail the support straps of the second elbow to a building frame member.
7. Continue installing the vertical portion of the chimney.
Note: If the inclined portion of the chimney passes through a floor or ceiling, a firestop spacer should be
installed to provide the firestop and support required. Be sure proper spacing in maintained between the
chimney and combustibles.
