INSTALLING OFFSETS
First, review the Offset Elevation Chart and see
Figure 39 for reference.
Step 1. Determine the offset distance where
chimney is to pass through the first ceiling-
dimension “A.” To find this point on your ceil-
ing, first determine the center point for a verti-
cal chimney following the instructions for ver-
tical installation.
Measure height to the ceiling from the top of
fireplace-dimension “B.” Use the appropriate
Offset Elevation Chart to find dimension “A.”
Mark point where you will drive your nail to
show the center point for your offset ceiling cut.
Step 2. Proceed by using the Straight Up Instal-
lation Instructions for cutting and framing ceil-
ing and roof openings.
