SAFETY PRECAUTIONS

• Wear eye protection.

• Wear gloves when handling panels and frame parts.

• 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
without proper ventilation.

• Provide proper ingress and egress to prevent
entrapment.

• 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. For safety reasons, those who
are not familiar with recognized construction methods

must seek the help of a qualified contractor.

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

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.

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 in
the diagram below.

2. Measure diagonally from corner-to-corner.

Insert shows how the support post is attached to the
base channel.

9. Continue with the next procedure.

IMPORTANT: Customer must determine how to attach
the assembled greenhouse to the permanent structure.
Fasteners for this procedure are not included due to the
variety of exterior finishes.

All silicone, fasteners, and weather stripping included
with this greenhouse are used during the construction of
the greenhouse.

Consult the services of a qualified contractor for
suggestions to secure and seal the greenhouse to the
permanent structure.

FRAME ASSEMBLY

After assembling both gable end frames and sidewall
frames, the assemblies are attached to each other to
construct the greenhouse frame.

NOTE: The greenhouse frame must be assembled on a
clean, flat surface such as a driveway or patio. An uneven
surface will not allow the sides and ends to join properly.
In many instances, the greenhouse frame can be moved
(with assistance) to the site after it is assembled or onto the
optional base if that was purchased.

The frame in the following photos may be of a different
model. The assembly process is the same. Consult
diagrams in the Quick Start section for details.

Complete the following steps.

1. Position the assembled frame sections as shown
below.

3. Slide a red-headed bolt into the bolt track of the end
wall frame support (14). See inside view below.

Slide red bolt
into the track.

9. Verify that the end wall lower support is seated to the
top of the sidewall base rail.

10. Tighten the bolt to secure the sidewall base rail to the
end frame lower support.

11. Recheck all bolts to verify they are tight.

12. Repeat the procedure to connect the remaining gutter
rail ends to the end wall frame of the greenhouse to
complete the assembly of the greenhouse lower frame.

IMPORTANT: See the Exploded Frame diagram in the
Quick Start section if you are assembling the 104715
home-attached greenhouse. The 104715 frame

includes a 2-piece base rail for the sidewall, a
2-piece gutter rail, and a 2-piece ridge beam.

The ridge beam connects the two end wall frame
assemblies at the peak. Because it is the main support of
the roof framing, the ridge beam is installed before the roof
rafters.

For the 104715 greenhouse, consult the EXPLODED

FRAME COMPONENTS diagram in the Quick Start section
for important information before you continue.

Complete the following steps to install the ridge beam:

1. Choose a bolt and slide it into the bolt track of the
upper support for one end wall.

NOTE: Bolt will slide to the bottom of the track. Use a
small piece of tape to keep it near the peak where it is
used.

2. Locate roof parts and unwrap them.

3. Select the ridge beam (this will be the longest frame
member in the package) and position it between the
end wall frames at the peak. Assemble the beam for

the 104715 frame. See Exploded Frame diagram.

REMEMBER: Photos show the inside of the
greenhouse unless otherwise noted. All bolt tracks are
positioned to the inside of the greenhouse.

Photo above may be of a similar but different model.

13. To this point, all gutter rails are secured to the end wall
frame assemblies and all angle bracket bolts are tight.

14. Continue with installing the ridge beam of the roof.

INSTALL THE ROOF RAFTERS

View below shows the ridge beam as seen from the
inside looking at the peak of the end wall frame. Bolts
are slid into the pre-punched mounting slots in the
ridge beam.

Ridge Beam

The roof rafters are installed with the bolt tracks to the
inside of the greenhouse. Longer greenhouses (104713
and 104715) include a support (52) with double bolt tracks.

ATTENTION: Greenhouses 104713 and 104715 include a
main support (52) with a double track (see photo below);
begin with Step 1 and install this support (52) first.

For greenhouse 104711: If you are assembling the roof for
the 104711 greenhouse, begin with Step 11.

Complete the following steps as instructed:

1. Move the double track support (52) to the inside of the
assembled frame and locate the required bolts and
nuts.

NOTE: The double track support (52) is installed in
line with the double bolt track vertical support (14) of
the sidewall. The double track support (52) is installed
so it is attached to the sidewall vertical support (14) as
shown below. See Special Note on the Roof/Sidewall

Frame diagram in the Quick Start section if you are
assembling the 104713 greenhouse.

4. Add a nut to the bolt installed in Step 1 and slide the
bolt toward the peak and into the mounting slot of the
ridge beam.

5. Verify that the ridge beam is seated properly and
tighten the bolt.

6. Repeat the procedure to secure the remaining end of
the ridge beam.

2. Count the number of bolts needed to mount the 94,
100, and 101 brackets, and slide these into the bolt
track of roof support 52 and sidewall support 14.

3. Add mounting bolts and one additional bolt to the
double-track sidewall support (14) for the horizontal
brace (103). Use tape to keep bolts from sliding out of
the track.
