YOUR NEW CEDAR GREENHOUSE 

Introduction

Thank you for buying an Alton Cedar Greenhouse.

Please read carefully through these instructions

before beginning to put your greenhouse up. 

Optional Extras

It is extremely important that you assemble your

optional extras in the correct position. Throughout

these instruction references will be made to each

optional extra. Please refer to the appropriate page

or leaflet for full details.

Safety advice

It is advisable that the greenhouse should be

assembled by two people. Particular care should

be taken when handling glass and the wearing of

gloves is strongly recommended. Favourable

weather conditions should be chosen. Do not try

to erect the building in windy conditions - the

panels are difficult to handle in high winds.

All side frames should be suitably propped until

the roof frames are secured.

Keep children and pets away until the work is

finished.

Take your time - rushing causes accidents.

Fitting service

Please call your local dealer if you would like to

have a quote for the erection of your greenhouse

by an installer.

Tools required to erect the greenhouse

Drill & bits (for pilot holes), screwdrivers (for slot

and posi-drive), spanners 10mm & 17mm, small

hammer, pliers, spirit level, step ladder, tape

measure, bradawl, mastic gun, saw & props.

Planning and preparation

All of the illustrations relate to a 10’6”/3.20m long

Amateur Greenhouse. For other models you will

have a greater or smaller number of Side and Roof

Sections for your chosen model.

Before you commence assembly of the frame it is

advisable to pre-determine the layout of individual

sections to ensure the roof vents are in the

position you require. To assist you in this each

section has been individually wrapped and

labelled. 

If you do not want to cut one of the roof cover

strips please avoid positioning a roof vent at either

end of the greenhouse.

A bradawl or drill should be used to pilot all screw

holes, especially on the shelving and staging, to

help prevent the timber from splitting. Sometimes

the pre-drilled holes in the frames can be blocked

- simply insert a screwdriver to clear them. 

Unpacking the greenhouse

Before removing all the packaging please note the

individual named pieces of greenhouse. This is not

only a convenient way to check you have all the

correct sections, but also to help you when

determining the layout and assembly of your

greenhouse. You will also notice all fixtures, nails,

screws, bolts etc., come pre-packed and labelled

for your convenience. Keep these in their bags

which will make identification easier.

If using a knife be careful not to cut into the cedar

wood.

Future Reference

Please keep these assembly instruction safe as you

may need them for reference in the future.
