Before you begin, take time to complete this check list.
Take inventory of all parts using the parts list in MANUAL 3.
Be cautious where you place the polycarbonate panels as they will burn grass or
plants if left on top of them in direct sunlight. Note that clear film side of panels
should always face the sun and white film side faces inside greenhouse. Panels may
scratch easily so be careful what you clean them with.
Plan out when and where you are going to place the greenhouse, we recommend
that you place it in an area that will receive direct sunlight and will be protected from
the wind as much as possible
It will take at least (2) people to put the greenhouse together, if assembling any
greenhouse longer than 8x16 you will need at least (3) people.
Before you build, make sure you are allowed to build it! Consult all building codes,
as well as City or Municipality ordinances and HOA’s, as you may need a permit or
documentation before you build.
Contact your insurance company to make sure your Grandio Greenhouse will be
covered on your policy.
Call your local utilities companies before digging.
Do not attempt to begin construction on a windy day, plan to complete assembly in
one day. Damage caused by incomplete assembly is not covered by warranty.
Your greenhouse should be built on a flat, level surface allowing for drainage.
Read all 3 Manuals to get familiar with all pieces and parts prior to beginning assem-
bly. Follow the steps outlined in the order presented!
IMPORTANT! PLEASE READ BEFORE BEGINNING ASSEMBLY

• SECURING BASE KIT TO SURFACE FOR ALL SIZES
• WARRANTY
IMPORTANT! SAFETY INSTRUCTIONS
FAILURE TO FOLLOW THESE WARNINGS MAY RESULT IN SERIOUS INJURY OR
PROPERTY DAMAGE AND WILL VOID WARRANTY.
To ensure safety, do not attempt to assemble this product without following the instructions carefully. Check entire
box and inside all packing material for parts and/or additional instruction materials. Before beginning assembly,
locate and read the instruction Manuals 1, 2, and 3. Complete assembly and proper usage are essential to reduce
the risk of accident or injury when using your Grandio Greenhouse.
CAUTION: Do not leave polycarbonate panels laying on grass, in direct sun light, or extreme heat. Keep in a cool dry place until
they are to be installed!! (May cause burning to plants or grass if left directly on top of them, also may damage panels due to the
protective film adhering to panels.) Panels may scratch easily.
* DO NOT USE SOLVENT BASED CLEANERS ON POLYCARBONATE PANELS.
• Each of the polycarbonate panels have a clear film side that should always face the sun, and a white film side which faces inside.
The clear side has a UV coating and we recommend marking a small “x” on a corner of each panel to determine which side has the
UV Coating as you cannot visually determine with your eye in the case of future disassembly.
• Due to shipping, the grooves of some of the aluminum profiles may be too small to insert into the polycarbonate sheet, you may
carefully use a screwdriver to pry the framework open so the polycarbonate sheet can be inserted smoothly.
• Do not use or store hot objects such as grills, blow torches, welding equipment, etc. in or near your greenhouse.
• Do not allow children or pets to play in greenhouse or in the set up area until assembly is complete.
• If using a ladder during assembly, use extreme caution.
• A clean level surface is essential to maintaining the solid integrity of the structure. Install the base correctly as described in this
manual for your surface. The greenhouse must be anchored down to a firm and level base. If not properly installed warranty will
be void.
NEEDED FOR ASSEMBLY
• Tape Measure • 2-4 Ladders For Larger Sizes • Safety Glasses
• Level • Work Gloves • Drill
• Carpenter Square • Permanent Marker • Folding Utility Table
• At Least 2 Adults • Masking Tape

SUMMIT BOX CONFIGURATION LAYOUT
We recommend laying all of your boxes out as shown on the graphic below for an organized assembly.
Locate your greenhouse size and situate your boxes near your assembly site as shown in the order listed below.
Inventory the parts and lay out on a tarp as to not lose items in the grass or dirt near your building site, a folding table is very helpful as well.
*See the reference diagrams for each greenhouse size in MANUAL 1. For more information about how the parts will go together and what makes
up each section for the assembly see MANUAL 2. See MANUAL 3 for detailed parts lists. See videos on our website at www.GrandioGreenhous-
es.com.
* If building a back door you will follow the instructions in the manual included with the Back Door Kit box, the parts will be in box GRA-SUM-BD.

PRE-PLANNING YOUR GREENHOUSE PLACEMENT
Pre-Plan The Placement Of Your Structure: The best placement depends on the features of your property, it is suggested in
most scenarios to have your greenhouse face South on its broadest side and to have the door face East or West depending on
typical wind directions in your area. Do not worry if your orientation will not allow for the suggested placement, as a greenhouse
that is facing North is better than having no greenhouse at all.
Avoid building your greenhouse at the base of a slope as these are often frost pockets where cold air collects, this will not be
good for your greenhouse in keeping the temperature up inside.
Allow enough room to get a wheel barrow in and around your structure. Be sure you have adequate room around the exterior
sides and rear of your greenhouse for maintenance of your property and the structure.
Drainage: Be sure the orientation will allow for proper drainage in and around your greenhouse.
Sunlight and Wind Protection: It is recommended that you place your greenhouse in an area of your property that receives the
most sunlight but is also somewhat protected by trees, fencing or your home for wind protection. The more direct sunlight will
keep the temperatures up during early spring and late fall. Typically the goal is to get at least 6 hours of sunlight daily throughout
the year.
Extreme Wind Conditions: If you live in a windy location there is no way to build a 100% storm safe greenhouse, but there are a
number of things you can do to minimize the chance of damage. Ensure that the base is level and square, be sure all panels are
secured in place and that all aluminum extrusions are tight. The main problem is usually that wind gets into the greenhouse and
the pressure pushes a panel out and then the force of the wind on the interior causes more damage. It is best if you are expecting
an extreme weather event that you disable any auto roof vents and make sure all doors and windows are closed and locked shut.
Also you may need to build a wind break for extreme condition areas where wind is constant and extreme.
Utilities: It is ideal for your greenhouse to have water, electricity and even gas plumbed into place before construction. This will
make watering plants and keeping temperatures and air circulation to the max efficiency.
You will need to choose an anchoring system prior to installation, see our website for options:
www.GrandioGreenhouses.com or call 1-866-448-8231
For Cement Base Installation: You will use Tapcon® style screws to secure your Flat Mount Base Kit to the concrete surface.
For Deck Base Installation: You will use wood screws to secure your Flat Mount Base Kit to the wood surface.
For Earth Installation: You will use the Grandio Summit Steel Base Kit with the BA-A1 / L-BOLT anchoring system. With this
method you will dig holes, place the L-Bolts into the ground and secure into place with quickrete.
* YOUR CHOSEN ANCHOR KIT OPTION SHOULD BE FOUND IN YOUR WELCOME KIT OR ACCESSORY BOX.

WARNING: BASE KIT MUST BE LEVEL AND SQUARE, AN UNLEVEL BASE WILL AFFECT THE INTEGRITY OF YOUR GREENHOUSE.
1. Align the Steel Base Kit to your desired location. Measure corner to corner to confirm square, check that all sides are level, then mark the
ground where the BA-A1 L-Bolts will reside with a marking paint. You will then move base aside in order to dig out the holes.
2. Dig out the holes for the BA-A1 anchors, then confirm the base is square and level again with the base kit moved back into place and BA-A1’s
in their respective holes. Check with your local building code for depth requirements.
3. We recommend you use a concrete mix such as Quikrete® fast setting concrete to secure the BA-A1 L-Bolts into place.
4. Follow the directions on your concrete mix. Confirm as the mix sets that the base is level and square. The BA-A1 L-Bolts may be adjusted up or
down by turning the nuts attached to each BA-A1 that sandwich the base kit to assist in leveling the base kit after curing.

* The Flat Mount Base is included in each Summit Greenhouse Kit. The Flat Mount Base is designed to be installed on a wooden deck or concrete
slab type surface. If you are using a Steel Base Kit for installing into the earth you will follow these instructions to assemble the Flat Mount
section, but will then attach the Flat Mount Kit onto your Steel Base Kit.
The Flat Mount Kit will be assembled as shown in this section, then secured to the surface of your choice using the proper anchoring hardware.
You will drill all holes into your surface for the entire base kit and temporarily affix into place, you will need to remove the front and back
sections in order to build your front and back walls as will be shown in the Summit Greenhouse Assembly Manual 2.
