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.
