3. Enclose the chimney where it passes through the living spaces to prevent contact with and possible dam-age to the

chimney.

4. Install ﬁrestop spacers at each ceiling level.

5. Install the proper chimney cap or chimney housing on the chimney to prevent the entry of rain and debris into the

chimney and to assure the proper venting of smoke.

6. Do not use more than four elbows in the chimney.

NOTE: To select the proper chimney height, refer to Figure 1. The ﬂue outlet must be a minimum of three feet above

the highest point where the chimney penetrates the roof and a minimum of two feet above all portions of the building

within ten feet. If the chimney is to include elbows to offset the chimney, refer to the Chimney Offset and Cap Installation

section of this manual. There must be at least two inches air space between all sections of the chimney and combus-

tible materials between ﬂoors.

1. Lay out, cut and frame openings through all ceilings and the roof at the point where the chimney will pass through.

Unless the chimney is to be offset, the point where the center line of the chimney will pass through the ceiling and

roof can be determined with a plumb line as shown by Figure 15. The ﬁreplace should be located in the planned

installation position. After the center line is established and a nail is driven to mark the point, the opening can be

cut if you are satisﬁed with the chimney location relative to ceiling and roof joists and/or any other obstructions. The

roof opening center line should be marked by driving a nail through the roof from underneath that will penetrate the

roof and can be located from the rooftop. If the chimney is to penetrate a pitched roof, the hole in the roof must be

rectangular instead of square and should be sized according to Table1.

2. Install the ﬁrestop spacer as required from beneath the ceiling unless the space above is attic space. In an attic, 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 "S" series 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 sec-

tions 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 diameter 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.
