YOU MUST READ THIS DOCUMENT BEFORE YOU
BEGIN TO ASSEMBLE THE SHELTER.

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.

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.

SAFETY PRECAUTIONS

• Wear eye protection and gloves when handling panels
and frame parts.

• Frame is metal. Use a portable GFCI 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

• 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.

• 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.

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.

IMPORTANT! INVENTORY THE PARTS

1. Open one box and use the Bill of Material included in
that box to inventory the contents. See Page 39 for Box

9-4 (104611) or Box 7-4 (104609) for cresting parts.

2. Return all parts and the Bill of Material to the box and
repeat the procedure for all remaining boxes.

3. Call Customer Service at 1.800.245.9881 to report
any missing parts before you begin assembling the
greenhouse.

BASE FRAME ASSEMBLY (OPTIONAL PURCHASE)

The base frame assembly provides a level, square surface
on which to set the greenhouse frame. It is strongly

recommended that you use this base.

The optional base (additional purchase required) is
assembled and squared, its posts set into the ground.
It is then anchored in place using ground posts or
other approved anchoring methods described in these
instructions.

This base is an optional purchase. Contact your sales
consultant at 1-800-245-9881 to purchase the base.

The following steps describe how to assemble the optional
base frame for the greenhouse.

1. Unpack the base kit to identify the parts.

NOTE: The base is assembled upside down and then
is flipped when it is positioned on the site.

2. Identify the base channel lengths used for the ends
(width) and the sides (length).

GROWSPAN™ ESTATE ELITE GREENHOUSES

Cut these only if you plan to place the frame, and
ultimately the greenhouse, on a concrete slab.

the base over and set it on the site.

Top of
base

Before the support posts of the base are driven into the
ground and before the assembled greenhouse frame is
set on and secured to the base, you must square the base
assembly and anchor the base to the site.

ATTENTION: If you are setting the base and greenhouse
on a patio or concrete slab, set the assembled base on site
and continue with the greenhouse assembly procedures
that follow. Do not square the base at this time.

This base and greenhouse require a level site. Before
setting the base or greenhouse frame (or both) in place,
you must level the site.

The easiest way to square the base is to measure
diagonally from corner to corner.

Complete these steps:

NOTE: The following procedure describes how to square
the base on a prepared site and drive the base support
posts into the ground.

1. Position the assembled base on the site as shown
below.

9. Continue with the next procedure.

NOTE: If additional legs are present, use the longer
bolts included with the kit to secure the legs to the
frame.

PACKING LIST NOTE (OPTIONAL BASE FRAME ONLY)

Some packing lists included with the optional base kit may show
J-clips as an included item. These J-clips are no longer used and
are not included in the shipped items.

The self-tapping screws are now included and are used instead.
Consult the anchoring instructions within this document for
additional information.

2. Measure diagonally from corner-to-corner.

Top of
base

NOTE: The frame is square when both measurements
are the same.

3. When the frame is square, tap the support posts into
the ground to set the frame in place and recheck the
measurements.

NOTE: Place a block of wood on top of the base
channel and support post and hammer on the wood to
protect the frame when driving the posts into place.

4. Continue to drive the posts to the desired depth.

NOTE: Use a level (or string a line) to verify that the
base remains level when set into the ground

5. After setting the base on the site, continue with the
greenhouse assembly.
