Installation Instructions
If the brighter cell is between the numbered temperature 
cells, position the panel between the corresponding 
temperature indicator lines (gure 2). Example: If the 
PanelThermometer reads 65, align the second panel to 
the 65 temperature indicator line on the rst panel. If the 
cell between the 65 and 100 is brighter, position the panel 
between the 65 and 100 temperature indicator lines. 
First Course 
Strike a level line around the house and install Shingle 
Starter Strip, holding it back 2-3/4" from each end of 
the wall. If you plan to use Cedar Impressions Mitered 
Cornerposts, 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. 
1. Create a straight edge 
on the right side of the 
panel by cutting the top 
two shingles so they are 
ush with the bottom 
shingle, as shown in 
gure 3. Cut 4" off the 
top course of the panel 
at the 4 mark on the 
tape measure located 
on the hanger, below 
the nail slots.
2. 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 
cornerpost or receiving 
channel (gure 4). 
Leave 1/4" space 
between the panel 
and the corner for 
expansion. If you are 
planning to install the 
Mitered Cornerpost, 
space the panel 2-3/4" 
from the corner.
3. Fasten the panel to the wall by rst 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 (gure 5). Leave 
1/8" to 1/16" between the nail heads and the panel to 
allow freedom of movement during normal expansion 
and contraction. The T5 panel features NailStop™ to 
guide in correct nail head clearance.
4. Install the next panel by positioning it below the starter 
strip and next to the rst panel. Push in gure 6. Space 
the second panel according to the panel temperature at 
the corresponding to position panel into place. Gently 
tap the outside of the HammerTapper™ ribs to properly 
position the panel left or right.
5. 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 using the procedure in step 3.
6. Continue to install remaining panels of rst course as 
described in steps 3 through 5.
Second Course
7.   Cut 30" off of the right side of the T5 shingle at indicator 
30, which is located on the hanger below the nail slots, 
cutting straight through the panel (gure 7). Drill a 
3/16" hole in the center of the nail hem and nail siding 
through this hole to control direction of expansion and 
contraction. Another option is to nail each end of a nail 
slot located at the center of the panel.
8.  Set the spacing using the PanelThermometer and 
temperature indicator lines and repeat steps 4-6.
Third Course
9.  Continue to stagger panel courses according to steps 1 
and 7, alternating each time to ensure a random shingle 
pattern up the wall.
NOTE: If two temperature cells on the 
PanelThermometer show a color change, use the 
brighter color as the indicator.
