REQUIRED TOOLS

The following list identifies the main tools needed to
assemble the shelter. Additional tools and supports may be
needed depending on the structure, location, and
application.

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.

Tape measure or measuring device•

Marker to mark locations on the pipes•

Variable speed drill and impact driver (cordless with •

UNPACK AND IDENTIFY PARTS

The following steps will ensure that you have all the
necessary parts before you begin to assemble the shelter
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 customer­supplied 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.

Unpack the contents of the shipment and place where 1.
you can easily inventory the parts. Refer to the Bill of
Materials/Spec Sheets.

Verify that all parts listed on the Bill of Materials/Spec 2.
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).

LAY OUT THE BUILDING SITE

After the site is prepared, lay out the 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•

Identify a corner where a ground post will be positioned 1.
and drive the first 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 eleven (11)
inches above the finished grade when properly driven.

Ground
Post

CLEARSPAN™ GREENHOUSES

Use a transit or line level to drive the second corner 3.
post to the same depth as the first ground post.

String a line at least as long as the building from the 4.
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.

After squaring the position of the building, measure 5.
the length (center-to-center) and drive the next corner
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.

After the first corner ground post is in place, string a 2.
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.

Repeat the same step for the last corner post. 6.

NOTE: The distance measured diagonally between
corner posts must be equal for the building to be
square.

Check all dimensions (and adjust if needed) before 7.
driving the remaining posts to the required height.

After all corner posts are accurately installed, tie a 8.
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.

Use a tape measure to mark the 48" on-center 9.
locations of the remaining ground posts.

Drive the remaining ground posts into the ground at the 10.
required 48" on-center width and the height identified
by the string.

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. See Step 1 if needed.

ends of the pipes and secure each joint with a Tek
screw.

NOTE: The baseboards (strongly recommended) shown in
the diagrams throughout these instructions are not included
and must be supplied by the customer.

ASSEMBLE AND PRE-MARK THE PURLINS

The following steps describe one way to speed the
assembly process. Pre-marking the purlins ensures that an
accurate spacing of the rafter assemblies is achieved and
maintained during assembly.

Those familiar with the assembly of similar structures
may elect to skip this procedure and continue with the
ASSEMBLE THE FRAME procedure on the next page.

Gather the parts:

Pipe 1.315'' x 75'' swaged (#131S075)•

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.

NOTE: For longer frames, it may be easier to assemble
a few rafters at a time and then begin to assemble the
frame.

Once rafters are assembled, assemble the frame.3.

Revision date: 07.22.11

Select the required pipe sections for one purlin and 1.
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 and 3.
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:

Complete these steps to install the accessory framing:

Based on the installation requirements and precautions 1.
of the accessory, choose a location in the end wall to
mount the accessory, and cut a 1.5" x 1.5" frame tube
to the required length for framing.

Attach these horizontal frame tubes between the 2.
vertical frame tubes of the end wall (at the required

Once the door end of the greenhouse is covered with 13.
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 to 14.
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.

wall framing.

After identifying and marking the desired height of the 2.
door track on the end wall, determine the locations of
the track brackets.

Repeat the steps to install the remaining sliding track 5.
mounting bolts. All mounting bolts must be installed at
the same height on the end wall frame so that the track
is level.

After installing the mounting bolts, slide the two track 6.
mounting brackets onto the sliding door track.

Align the brackets with the mounting bolts and install a 7.
flat washer, lock washer, and a nut.

The dashed line above represents the sliding door
track. The arrows show where to attach the track
brackets to the end wall framing.

Drill a 3/8" hole through the corrugated polycarbonate 3.
panel and through the vertical end wall frame tube.

The hole must be level to mount the bracket and track
properly.

Insert a 3/8" carriage bolts through a hole from inside 4.
the building and tap it with a hammer to set it tight
against the end wall frame member.

Install a flat washer,
lock washer and nut to
secure the mounting
bolt to the end wall
frame.

Verify that the track is level and flush to the inside edge 8.
of the end rafter and tighten the 3/8" nuts. The carriage
bolts can be trimmed if desired.

Cut if desired

NOTE: The center track mounting bracket will cover
the joint where the separate track sections meet at the
center of the end wall.

After securing the track to the end wall frame, lift one 9.
door up and into place and insert the rollers into the
track.

Repeat the step to install the second door into the 10.
track.

Slide both doors to the center of the door opening to 11.
the closed position and adjust as needed to level the
doors so they meet evenly at the center.

Adjust the lower stay rollers as needed.12.

ASSEMBLE AND ATTACH SLIDING DOORS (continued) SHELTER CARE AND MAINTENANCE

After adjustments are made, slide one door to its open 13.
position and install two Tek screws through the door
track to prevent the door from sliding out of the track.

Arrows show the locations of Tek screws (two at each
end) used as door stops. Tek screws are installed
through the front of the door track.

Repeat the previous step for the remaining door.14.

Install the door handle in the desired location. Door 15.
handle is attached using Tek screws.

Use the FA4482B
Tek screws to secure
handle through the
polycarbonate panel
and into the door
frame.

Proper care and maintenance of the shelter is important.
Check the following items periodically to properly maintain
the shelter:

Regularly check the polycarbonate panels to see •
that these are secure and in good condition. Replace
damaged panels if needed.

Check connections and all fasteners to verify that they •
remain tight.

Do not climb or stand on the greenhouse at anytime. •
(See the ridge cap installation notes.)

Inspect the anchoring system to verify that all •
components remain tight and in good condition.

Remove debris and objects that can accumulate on the •
greenhouse. Use tools that will not damage the cover
when removing debris.

Remove snow to prevent excess accumulation. Use •
tools that will not damage the polycarbonate panels
when removing snow.

Check the contents of the shelter to verify that nothing •
is touching the polycarbonate panels that could cause
damage.

If the greenhouse is moved, inspect all parts and •
connections before it is reassembled.

Depending on the contents, construction of the shelter, •
shelter materials, and shelter location, the potential for
condensation exists. ClearSpan™ offers several items
that can be used to alleviate a condensation condition.
Please contact a ClearSpan™ representative for
additional information.

Continue by reading the 16. CARE AND MAINTENANCE
information that follows.
