INSTALLING OFFSETS

First, review the Offset Elevation Chart and see
Figure 39 for reference.
Step 1. Determine the offset distance where
No. 8 x 1/2" SMS
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.
