LAY OUT BUILDING SITE
After site is prepared, lay out building site.
Taking these steps
before
assembling the shelter saves
time and ensures that the structure is positioned as
desired.
Ground posts must be driven to the proper depth. Width of
the shelter is measured from the center of one ground post
to the center of the remaining ground post.
SQUARE THE SITE
Gather parts:
• Ground posts
• 5/16" x 2-1/2" hex bolts (FAG336B)
• 5/16" nuts (FALB02B)
1. Identify a corner where a ground post will be positioned
and drive the first ground post into the ground.
NOTE:
Insert ground post driver into top of ground post
to protect post and drive post.
Top of post will be one
(1) foot above finished grade when properly driven.
3. Use a transit or line level to drive the second corner
post to the same depth as the first ground post.
4. Sting a line at least as long as the building from the first
stake at 90°.
NOTE:
A transit can be used to ensure an accurate 90°
angle, or the 3-4-5 rule can be used. Refer to diagram.
Using multiples of 3-4-5 such as 6-8-10 or 12-16-20
helps to maintain an accurate 90° angle.
5. After squaring the position of the building, measure
the length (center-to-center) and drive the next corner
ground post.
6. Repeat the same step for the last corner post.
NOTE:
Distance measured diagonally between corner
posts must be equal for building to be square.
7. Check all dimensions (and adjust if needed) before
driving remaining posts to the required height.
8. After all corner posts are accurately installed, tie a
string line between tops of corner ground posts on the
same side of the shelter. String is used to identify the
tops of all remaining posts. String must remain tight
and level.
9. Use a tape measure to mark the 48" on-center
locations of the remaining ground posts.
10. Drive remaining ground posts at the required 48" on-
center width and the height identified by the string.
NOTE:
Verify that holes in posts are in the proper
position and that each post is plumb and driven to the
correct depth.
11. Continue with the
Rafter Assembly
steps that follow.
ATTENTION:
Position pre-drilled holes facing inside/
outside of shelter so they align with bolt holes in rafter
pipes.
To align bolt holes in ground posts with those in the
rafter
after driving posts,
insert a tapered rod or pry bar
into a ground post bolt hole and turn post.
2. After first corner ground post is in place, string a line
the width of building (center-to-center) and drive the
second ground post into the ground just enough to hold
it in place.
