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.

READ THIS DOCUMENT BEFORE YOU BEGIN.

Thank you for purchasing this GrowSpan™ greenhouse. When properly assembled and maintained, this product will provide years of reliable service. These instructions include helpful hints and important information needed to safely assemble and properly maintain the greenhouse. Please read these instructions before you begin.

If you have any questions during the assembly, contact Customer Service at 1-800-245-9881 for assistance.

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.

• 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.

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.

ASSEMBLY NOTE: Install Tek screws using a clutched drill driver running approximately 750 RPM while applying approximately 50 lbs of force.

Do not use an impact driver to install Tek screws!

SQUARE TUBING INSTALLATION

Use the 102897 square tubing for all end wall framing. Use the 104779 square tubing (plain ends) to secure overlap seam between roof panels.

ASSEMBLY PROCEDURE

Following the instructions as presented will help ensure proper assembly of your greenhouse. Failing to follow these steps may result in an improperly assembled and anchored greenhouse and will void all warranty and protection owner is entitled.

Steps outlining the assembly process are as follows:

1. Verify all parts are included in shipment. Notify Customer Service for questions or concerns.

2. Read these instructions, the Must Read document, and all additional documentation included with shipment before you begin assembling.

3. Gather the tools, bracing, ladders (and lifts), and assistants needed to assemble greenhouse.

4. Check weather before you install roof and polycarbonate panels. Do not install panels on windy or stormy days.

5. Re-evaluate location and site based on information and precautions presented in documentation.

PANEL AND RIDGE CAP INSTALLATION NOTE

Depending on available equipment, it may be necessary to construct a support structure to allow a person to reach top of greenhouse from outside.

If a support structure has to be used, design structure to support both the weight of structure and the person using it.

Use of a lift is strongly recommended.

CAUTION: Under no circumstances should support structure allow any force or weight to be applied directly to polycarbonate sheets! All supports must span

from rafter-to-rafter.

Consult a contractor if needed for additional information. Take the necessary steps to protect polycarbonate panels.

POLYCARBONATE PANELS ARE NOT DESIGNED TO SUPPORT WEIGHT.

NOTE: Position supports so they span from rafter-to-rafter to protect panels. DO NOT use materials that will damage or scratch panels. Cover panels to protect panel surface.

6. Prepare site (if applicable).

7. Assemble frame components in the order they are presented.

8. Assemble frame including struts (if equipped).

9. Consult MUST READ document and properly anchor assembled frame.

10. Install end wall framing.

11. Install, tighten, and secure end panels and doors.

12. Install main roof panels.

13. Read the care and maintenance information in next column.

CAUTION: DO NOT place support structure directly on polycarbonate panels; serious injury may occur. Polycarbonate panels are not designed to support excess weight.

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.

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 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 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 one (1) foot above the finished grade when properly driven.

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.

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.

2. After the first 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.

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 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.

11. Continue with the Rafter Assembly steps that follow.

ASSEMBLE AND PRE-MARK THE PURLINS

The following steps describe one way to speed the assembly process and eliminate the need to measure each purlin as it is installed. Pre-marking the purlins ensures that an accurate spacing of the rafter assemblies is achieved and maintained during assembly.

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.

ATTENTION: The XX" represents the remaining length required to reach the end of the shelter. Consult the Spec Sheet for part identification.

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

2. Verify that each pipe joint is properly seated.

NOTE: These pipes must be separated during the assembly procedure. Do not fasten them together at this time.

3. For the 48" rafter spacing, measure forty-eight and 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.

END PANEL INSTALLATION

After the end wall framing is attached to the greenhouse, attach the polycarbonate panels to the end wall framing. The steps that follow describe one way to complete the end wall panel installation.

The materials and parts needed to assemble the End Panels include:

• Polycarbonate panels and white vent tape

• Aluminum U-Channel profile (#104213)

• Aluminum 8' H-Channel profile

• Tek screws (#FA4484B)

Complete the following general steps to install the end wall panels.

1. Consult the panel location diagrams, select one polycarbonate panel, begin at the edge of the opening for the double door, and work to the outside edge of the end wall.

See the X in the diagram below for the first panel.

• Neo-bonded galvanized washers (#102921B)

Read the following information before starting:

• U-Channel profile is used to finish the roll-up side edges of the polycarbonate panels.

• H-Channel profile is used to join two (2) separate polycarbonate panels at the seam.

• Tek Screws and galvanized washers are used to secure aluminum channel and panels to end wall frame.

• Install the polycarbonate panels with the UV-protected side to the outside. Mark this side with a marker if needed after removing the protective film.

ATTENTION: The protective film must be removed from the polycarbonate panels. Allowing the film to remain intact and in direct sunlight will make the film difficult if not impossible to remove.

• During preparation, rest the edges of the panels on cardboard or other material to protect them from dirt and damage.

Dashed line and small arrows (above) show where to install the white vent tape. Do not install tape in any other location on any other end panels.

NOTE: Remove the protective film. When needed, an upper panel is cut to length after attaching it to the end wall frame and rafter.

Always remove the protective film and mark and install the UV-protected side to the outside of the greenhouse.

Mark UV Side

• Seal the bottom edge of the panels with white vent tape.

• Consult the polycarbonate panels (Quick Start section) for the location and lengths of each panel. The diagrams are located at the back of these instructions.

ATTENTION: Panels must be position as shown on the panel diagrams. Using a panel in the incorrect place can affect the placement of subsequent panels. In addition, the amount of aluminum profile used between panels and to finish the panel edges may not be adequate if additional seams are created. Begin at the door end of the building.

NOTE: Install all accessories (fans, vents, heaters, etc.) after installing all polycarbonate sheets.

2. Apply white vent tape to the bottom of the lower panel and then install the aluminum U-channel profile to the edge of the panel adjacent to the door as shown on the Polycarbonate Panels diagram.

INSTALL ROLL-UP PANELS

ASSEMBLE THE ROLL-UP SIDE CONDUIT

This model includes a roll-up side panel for each side of the greenhouse. The panel film material is typically shipped as a single, 6' roll. Complete the following steps:

1. Locate the roll of side panel for the roll-up sides and cut a length from the roll that is the length of the

greenhouse plus two (2) feet.

2. Stretch the roll-up panel out along the side of the greenhouse and center it from end-to-end.

Gather the parts:

• Pipe 1.315'' x 75'' swaged 17 GA (#131S0075)

• Pipe 1.315'' x XX'' plain 17 GA (#131P0XX)

• Tek screws (#FA4482B)

The roll-up side conduit assembly is attached to the bottom of the roll-up side cover material. This assembly runs the length of the frame and serves as the center pipe that the roll-up cover wraps around when it is opened to ventilate the shelter. This conduit is identical to the purlins that were

assembled and attached to the frame.

NOTE: The number of pipes used in the roll-up conduit assembly varies with the length of the greenhouse.

Roll-up conduit assemblies consist of multiple sections of swaged 1.315" pipe at 75" in length (part #131S075) and one (1) additional plain 1.315" pipe at a shorter length (part #131P0XX) determined by the greenhouse, where XX represents the remaining length required to complete the roll-up conduit assembly and to reach the end of the greenhouse.

Complete these steps to assemble the roll-up side conduit.
