CHIMNEY INSTALLATION

LOCATING CENTER LINE

You will need to lay out, cut and frame openings through all ceilings and the roof at the point where the chimney will pass through.

Place ﬁreplace in planned position for installation. 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. See Figure 16. Drive a nail in the center point.

Note: Make sure the chimney location is well away from ceiling and roof joists and/or anything else that might be in the way.

Drive a long nail through the roof from underneath to mark the roof opening center line. Make sure the nail is long en ought to go through the roof and be seen on 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 Table 1.
