See pages 86 and 87.
Note: Do not drive center-pin nails tight. Leave 1/8"–1/16" 
between the nail head and the panel to allow the panel to 
move freely during normal expansion and contraction.
First course
If you are planning to use mitered corners, you MUST use an 
A + B cut pattern to start each course. This pattern ensures 
proper fit into mitered corners. 
Strike a level line around the house and install Cedar Impressions 
Metal Starter. If you plan to use Mitered Cornerpost, make sure 
the starter strip is installed to the edge of the corner. An alternative 
method of starting Cedar Impressions is to use J-channel in place 
of starter strip to receive the bottom edge of the panel.
Create a straight edge on the right side of the panel by cutting the 
top shingle so it is flush with the bottom shingle. Cut the end of 
the top course of the panel at indicator “A,” which is located 
above the nail slots.
Starting on the right side of the wall, hook the bottom locking leg 
of the panel into the starter strip and slide panel into the corner-
post or receiving channel. Leave 1/4" space between the panel 
and the corner for expansion. If you are planning to install the 
Mitered Cornerpost, space the panel 3" from the corner.
Fasten the panel to the wall by first nailing through the round 
center hole in the nailing hem at the top of the panel. Continue 
nailing the panel with 5 nails: one in the right-end nail slot and one 
at each of the QuickReference
™
 Nail Mark Indicators. Leave 1/8" 
to 1/16" between the nail heads and the panel to allow freedom of 
movement during normal expansion and contraction.
Install the next panel by positioning it below the starter strip and 
next to the first panel. Push in and up to lock the panel into the 
starter strip and the side tabs of the first panel. Space the second 
panel according to the panel temperature at the corresponding 
temperature indicator lines.
Nail the panel into position starting with the round center hole and 
then placing the next nail in the right-end nail slot (which overlaps 
the previous panel’s left-end slot) so that the nail goes through 
both panels’ nail slots simultaneously. 
Continue nailing the rest of the panel.
Continue to install remaining panels of first course as described.
When a window or doorway breaks a course, continue the 
application as if the opening were not there.

PRO TIP: When installing Cedar Impressions 
over foam insulation, extra care needs to be 
taken to verify that adequate space is left 
between all nail heads and the panel.
