ABOUT THIS DOCUMENT
This document is an Assembly Guide intended for persons who
have a moderate level of experience building small structures.
It is specific to the six-meter Riga XL VI, but can be applied to
Riga XL models of other lengths. If you are an experienced Riga
greenhouse builder, this is the guide for you. Keep these pages
for reference as you proceed with your assembly project.
If you lack experience, or if you wish to approach building your
Riga XL with all uncertainties resolved, you should download
and study the Riga XL Owner’s Reference Manual. It is
enhanced for online reading and is packed with valuable
information that can be otherwise gained only from experience.
Once you understand the details you can refer to the Assembly
Guide throughout your project to assure a trouble-free
experience and optimum results.

INTRODUCTION
Welcome to the Exciting World of Riga XL Ownership
Congratulations on your wise decision to acquire a Riga XL greenhouse. You have chosen the finest
personal greenhouse available.
This manual will guide you through all aspects of Riga XL ownership with special emphasis on assembly.
Please read it thoroughly, even before you unpack your shipment, and refer to it throughout the
assembly process. If you follow the instructions and use the recommended tools, you should be able to
easily assemble the greenhouse by yourself.
Riga XL Models
All Riga XL models are identical in width and height but there are five different lengths. The model
variations are identified by a Roman numeral suffix equal to the number of 1-meter length sections for
that model.
The Riga XL VI is the standard 6-meter length and is the subject of this manual. Available by special
order are the smaller Riga XL IV and Riga XL V, which are 4 and 5 meter lengths respectively. Also
available by special order are the stretch models Riga XL VII, Riga XL VIII, and Riga XL IX, which are 7, 8,
and 9 meters long respectively.
The models differ only in the lengths of the horizontal side profiles, the number of side glazing panels
and curved center profiles (arches), the number of roof windows and window openers, and the
quantities of supporting fasteners and seals. The horizontal side profiles for all models are one piece
except those of the Riga XL IX which are two pieces spliced near the center. The IX model includes a
robust welded aluminum truss for additional support of the roof beam at the splice.
Available Options
Three options and an accessory kit are manufactured for the Riga XL.
A shelving kit to be installed along one wall.
A door extension kit to lower one door if the greenhouse is built on a stem wall.
An aluminum foundation frame to use if you want your greenhouse at grade level.
Adjustable hanger accessory kit provides attachment points for plant support.
Two shelving kits are required if you want shelving on both sides, and two door extension kits are
required if you want both doors lowered into stem wall openings.

RECEIVING INSPECTION
Your Riga XL came all the way from Germany without damage, but domestic motor freight will expose it
to more serious hazards. Have a camera ready when your Riga XL is delivered and carefully inspect the
packages for damage before the delivery driver leaves. The polycarbonate panels are most vulnerable; a
gentle kiss from a fork lift tine can do serious damage.
Photograph any damage and describe it on both your copy and the driver’s copy of
the Bill of Lading. This evidence will be needed to file an insurance claim.
Immediately notify Exaco Customer Service at [phone] or [phone].
Take Inventory
One of the most helpful things you can do to make your project go smoothly is to carefully inspect and
inventory the materials in your shipment. This will familiarize you with the parts and give you time to
replace any that are missing or damaged before you start construction. An illustrated check list is
provided in this section to help make inspection easy and accurate. Report any shortages or damage to
Exaco Customer Service within 30 days.
Your Riga XL VI will arrive on a very long pallet. Bound to the pallet are two large flat bundles of glazing,
two curved wrapped bundles, and three long boxes. In addition to the pallet is a very long cardboard
tube containing a fourth long box. If you ordered any accessories you will receive additional boxes or
bundles. Some accessories, such as heaters, ventilators, and solar lights, might be shipped separately.
Start your inspection with Box 3 and continue with Box 2 and then Box 1. Inspect Box 4 last. Then open
and inspect Arch bundles 1 and 2 and finish with the Glazing bundles.
Components are identified by Pos. numbers. The extruded aluminum components are referred to as
profiles. Some of the extruded parts are referred by more specific names, such as edge stay bar,
crossbar, lateral supports, roof beam, and reinforcement bar.

9
Box 3: Small Parts
Box 3 contains the small parts, most of which are fasteners. Several sizes of screws may be mixed in a
single bag. Sort and count them, then put each size in an individual marked bag. Count carefully; extra
screws are rarely provided.
