FRAME ASSEMBLY (CONTINUED)
SQUARE THE ASSEMBLED FRAME
Gather the parts: Measuring tape and Tek screws
Complete these steps:
1. Square the frame by measuring diagonally corner-to-
corner and align all rafters as shown below.
2. Verify that the width of each rafter is 20' center-to-
center. The frame is square when the two diagonal
measurements are the same. See previous diagram.
3. Continue by anchoring the frame.
ANCHOR THE FRAME
Once the frame is anchored properly, continue with these
instructions.
WARNING
: Securing the rafter mounting feet (if
equipped) to baseboards set on the site is not a
substitute for properly anchoring the shelter. You must
anchor the shelter as described in the MUST READ
document.
FAILING TO PROPERLY ANCHOR THE SHELTER
WILL RESULT IN DAMAGE TO THE SHELTER AND
MAY CAUSE PERSONAL INJURY.
READ THE MUST READ DOCUMENT TO PROPERLY
ANCHOR THE SHELTER.
After anchoring the frame, check the frame for rough
edges as described in the following procedure.
2. Remove the bolts and attach a strut between the band
clamp on the purlin and the band clamp on the end
rafter. Position the strut so that it forms a triangle as
shown below.
Actual strut and position may vary.
FINAL FRAME CHECK
1. Return to the frame connections and verify that all bolts
are tight.
2. Verify that each purlin splice is secured with a Tek
screw.
3. Verify that each purlin is secured to the end clamp and
cross connector and that each cross connector and
end clamp is secured to the rafter. See diagram below.
4. Inspect the frame for sharp areas that could damage
the cover. If found, file smooth and cover with layers of
duct tape to protect the cover.
5. Verify that all bolts are positioned with the heads to the
outside of the frame. Tape the bolts and rafter joints
before
installing the cover.
6. Continue by installing the main cover.
