SAFETY PRECAUTIONS
• Wear eye protection.
• Wear head protection.
• Wear gloves when handling metal tubes.
• Use a portable GFCI (Ground Fault Circuit Interrupter)
when working with power tools and cords.
• Do not climb on the greenhouse or framing during or
after construction.
• Do not occupy the greenhouse during high winds,
tornadoes, or hurricanes.
• Provide adequate ventilation if the structure is
enclosed.
• Do not store hazardous materials in the greenhouse.
• Provide proper ingress and egress to prevent
entrapment.
ANCHORING INSTRUCTIONS
Prior to assembling this greenhouse, please read the
MUST READ document included with the shipment.
WARNING: The anchor assembly is an integral part
of the greenhouse construction. Improper anchoring
may cause greenhouse instability and failure of the
structure. Failing to anchor the greenhouse properly
will void the manufacturer’s warranty and may cause
serious injury and damage.
LOCATION
Choosing the proper location is an important step before
you begin to assemble the structure.
The following suggestions and precautions will help you
determine whether your selected location is the best
location.
• Never erect the structure under power lines.
• Identify whether underground cables and pipes are
present before preparing the site or anchoring the
structure.
• Location should be away from structures that could
cause snow to drift on or around the building.
• Do not position the greenhouse where large loads
such as snow and ice, large tree branches, or other
overhead obstacles could fall.
• Always check local building codes before you begin.
SITE
After choosing a location, proper preparation of the site is
essential. The following site characteristics will help ensure
the integrity of the structure.
• A level site is required. The site must be level to
properly and safely erect and anchor the structure.
• If the site is not level, use footings to provide a secure
base to assemble the structure. Pre-cast concrete
blocks, pressure-treated wood posts, or poured
footings are all acceptable when properly used. (Some
shelters use ground posts or rafter feet.)
• Drainage: Water draining o the structure and from
areas surrounding the site should drain away from the
site to prevent damage to the site, the structure, and
contents of the structure.
WARNING: The individuals assembling this structure
are responsible for designing and furnishing all
temporary bracing, shoring and support needed during
the assembly process. For safety reasons, those who
are not familiar with recognized construction methods
and techniques must seek the help of a qualified
contractor.
POLYCARBONATE PANELS
Do not allow panels to remain in direct sunlight with
protective film in place. Doing so will cause protective
film to become difficult if not impossible to remove before
installation.
Store panels indoors or cover with a light-colored
tarp until you are ready to install.

LAY OUT BUILDING SITE
After the 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.
Drive ground posts 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 the parts:
• Ground posts
• 5/16" x 2-1/2" machine bolts
• 5/16" nuts
1. Identify a corner where a ground post will be positioned
and drive the rst ground post into the ground.
NOTE: Insert the ground post driver into the top of
the ground post to protect the post and drive the post
into the ground. The top of the post will be twelve (12)
inches above the nished grade when properly driven.
3. Use a transit or line level to drive the second corner
post to the same depth as the rst ground post.
4. String a line at least as long as the building from the
rst 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.
Ground Post
Outside of
Shelter
Inside of Shelter
ATTENTION: Position the pre-drilled holes facing to the
inside/outside of the shelter so they can be aligned with
the bolt holes in the rafter legs.
To align the bolt holes in the ground posts with those
in the rafter after driving the ground posts, insert a
tapered rod or pry bar into a ground post bolt hole and
turn the post using the rod or pry bar.
2. After the rst corner ground post is in place, string a
line the width of the building (center-to-center) and
drive the second ground post into the ground just
enough to hold it in place.
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: The distance measured diagonally between
corner posts must be equal for the building to be
square.
7. Check all dimensions (and adjust if needed) before
driving the remaining posts to the required height.
8. After all corner posts are accurately installed, tie a
string line between the tops of the corner ground posts
on the same side of the shelter. The string is used to
identify the tops of all remaining ground posts. The
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 the remaining ground posts into the ground at the
required 48" on-center width and the height identied
by the string. See Step 1 if needed.
NOTE: Verify that the holes in the ground posts are in
the proper position and that each post is plumb and
driven to the correct depth.
