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 off 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.

UNPACK AND IDENTIFY PARTS
The following steps will ensure that you have all the
necessary parts before you begin to assemble the shelter
frame.
Unpack the contents of the shipment and place where1.
you can easily inventory the parts. Refer to the Bill of
Materials/Spec Sheets.
Verify that all parts listed on the Bill of Materials/Spec2.
Sheets are present. If anything is missing or you have
questions, consult the Pictorial Parts Guide and all
diagrams for clarification, or contact Customer Service.
NOTE: At this time, you do not need to open the plastic
bags containing smaller parts such as fasteners or
washers (if equipped).
SPECIAL NOTE: Baseboards for Frame
These instructions describe installing a baseboard
(recommended) at ground level along each side of the
frame. The baseboard runs from the front to the back of the
frame.
This baseboard is not included with the shipment and must
be supplied by the customer. Treated or recycled plastic
lumber works well for a baseboard.
Use the included 1/4" x 4" (FAH009B) carriage bolts
and the 1/4" zinc nuts (FALB01B) to attach a customer-
supplied baseboard. Depending on the dimensions of the
baseboard, alternative customer-supplied fasteners may be
needed.
During the installation, align the baseboard with the center
of the end rafter. Do not allow the baseboard to extend
beyond the end rafters at either end of the frame. Doing so
will interfere with the installation of the end wall corrugated
panels.
The baseboard, when installed properly, helps prevent the
ground posts from sinking into the ground when anchored.
Depending on the building, it also provides a surface to
attach struts or other building components.
Consult these instructions or contact Customer Service for
additional information regarding baseboards.

Pipe 1.315'' x XX'' plain (#131P0XX)•
Marker and tape measure•
NOTE: The purlins are part of the assembled frame and
run perpendicular to the rafter assemblies. Each purlin
consists of 1.315" x 75" (#131S075) swaged pipes (number
is determined by shelter length) and one (1) 1.315" x XX"
(#131P0XX) plain pipe.
The XX" represents the remaining length required to reach
the end of the shelter. Consult the Spec Sheet for part
identification.
Select the required pipe sections for one purlin and1.
connect these by inserting the swaged ends of the
pipes into the plain ends until the entire purlin is
assembled.
NOTE: Assemble the purlins in a location that is
accessible during the assembly of the frame, but will
not interfere with the process of lifting and setting the
rafters.
Verify that each pipe joint is properly seated.2.
NOTE: These pipes are separated during the assembly
procedure. Do not fasten them together at this time.
For the 48" rafter spacing, measure forty-eight and3.
three-quarters inches (48-3/4") from one end of the
assembled purlin and mark the distance on the pipe.
NOTE: This first measurement is three-quarters (3/4)
of an inch longer than the on-center rafter spacing
to account for the length of purlin pipe that extends
through the end purlin clamp of the first end rafter.

A NOTE ABOUT INSTALLING THE END WALL
FRAMING FOR OPTIONAL HEATERS, VENT FANS, AND
MOTORIZED SHUTTERS (if equipped):
Optional accessories such as heaters, vent fans and
motorized shutter units are typically installed or attached
to the end walls of this greenhouse. Additional horizontal
framing (included) is installed between the vertical end
wall frame tubes to mount these accessories. The spacing
shown for the end wall supports on the end frame diagrams
may be too narrow for the installation of some larger
accessories.
Diagrams do not show framing for the accessories.
When framing the end wall, consult the installation
instructions for the accessories (if equipped), or measure
the width of the accessory to accurately space and position
the end frame tubes.
Consult the panel installation diagrams in the Quick Start
section to identify the verticals that can be moved.
MOVE ONLY THE VERTICAL SUPPORTS LABELED
AS NC (NON-CRITICAL). See Quick Start diagrams.
Before installing any greenhouse accessory, adhere to the
following:

END PANEL INSTALLATION
After the end wall framing is attached, the end wall panels
are installed.
The following procedure describes one way to install the
end panels. This procedure installs the panels so the
corrugated ribs run horizontally.
Complete these steps to install the end panels.
NOTE: End panels overlap each other and are attached to
each frame member of the end wall and to the rafter.
Use Tek screws (#FA4482) and washers (#102921) to
secure all polycarbonate panels to the framing.
ATTENTION: Both end walls are covered using 4' x 8'
panels. Consult the Front and Back End Panel Details
diagrams in the Quick Start section of this document.

end panels, cut all panels to the width of the end wall
using the rafter as a guide.
ATTENTION: The roof panels can be installed on the
outside of a baseboard as shown in the next photo, or
flush with the top edge of the baseboard (not shown).
If you want to attach the roof panels to the outside of a
baseboard, use the installed baseboard as the outside
edge of the end wall at the bottom when cutting the
lower end wall panels to width. See the photo in the
next column for details. Use the rafter as the outer
edge of the end wall if you install the roof panels flush
to the top of the baseboard.
The gray bars in the photo below represent the
horizontal ribs of the corrugated panels. The dashed
line represents the edge of the roof panel that is
installed in the next procedure.
The roof panels are attached to the outside of the
installed baseboard as shown above. When cutting
the corrugated end panels to the proper width, cut the
panel so that it extends beyond the end rafter to cover
the small area above the installed baseboard.
ATTENTION: Allow the roof panels to extend beyond
the end of the rafters an inch or so to create a drip
edge.
Panels can be installed to the top of the baseboard.
Move to the remaining end wall and repeat the steps to14.
install the end panels for that wall.
NOTE: The width of the end wall determines how
the end panels are installed. When setting the end
panels in place, the excess end panel material can be
removed, or the next panel can overlap it, depending
on how much panel remains.
End panels are attached to each frame member of the
end wall and to the rafter. Panels must overlap each
other.
