Introduction Thank you for purchasing your new Alton greenhouse. We recommend you familiarise yourself with the instructions and read all safety information before you commence assembly. This instruction manual is also available online at www.greenhousepeople.co.uk in the technical help section should you need to reprint it. Should you require any additional advice you can always call us on 01782 385409.
Overview To build your new greenhouse you will need the following tools: Spirit Level Pencil PZ2 Screwdriver Bit Cordless Screwdriver (2 would be ideal, 1 to drill and 1 to screw) 4mm Drill Bit 7mm Masonry Bit Hammer Drill Hammer Wooden/Rubber Mallet Tall step ladders x 2 There are 8 different types of screws used in the construction of the greenhouse.
Choose a site where the greenhouse is relatively easy to get to and convenient to bring water to and possibly a supply of electricity. Finally, and most importantly, choose a site where your Alton Greenhouse will look right so that it will complement your garden.
Side Assembly To start building your greenhouse begin by laying out the components for your sides flat on the ground like the diagram below. Use the tables below to identify your building length and the components with the part numbers and sizes. First of all drill pilot holes through the bottom of each mortise on the cill section (diagram 2, page 9).
Side Assembly Internal Diagram 2 Pilot hole, it is easiest to drill Make sure the side bars are pushed all the down through the way in, you may find they need a light tap middle of the with a wooden mallet or something similar. mortise to make sure you get the (If you are going to glue your joints this is the...
Rear Assembly Internal EV0413 Dia. 5 Dia. 6 EV0406 As with the side cills you will need to drill pilot holes in Diagram 5 the bottom of the mortise holes (diagram 6). Assemble the gable glazing bars (EV0489) with the rear cill flat on the ground as you did with the side sections.
Page 9
Rear Assembly Now slot the 2 longer gable bars into the cill. These also need to locate with the middle Internal rear purling (diagram 7) . Diagram 7 Dia. 7 Next fit both left and right purlings to the standard glazing bars (EV0489). These are handed parts and it is important to fit them the correct way round.
Page 10
Rear Assembly Internal Dia. 9 Dia. 8 You will need to drill a pilot hole in the bottom of each side corner bar as shown in diagram 8. This should come through half way up the mortise slot. Now slot the side corner bar into place, fix the bottom of the bar with an 80mm screw.
Page 11
Rear Assembly Pilot hole Once the side corner bars are secure slot here the above purling glazing bars into place. With all of the gable bars in place drill pilot holes through the lap joints at the end of Internal each bar.

Rear Assembly Diagram 12 External Dia. 13 Dia. 12 Diagram 13 With all the components now in place flip the gable end over so you now have the outside edge facing you. Be careful doing this as some of the parts are not completely supported, it is a good idea to have a helper at this point.
Page 13
Rear Assembly With the outside face of the gable still facing you slide the rear purling brace (EV0412) under the frame (use cardboard or something similar to protect this part when doing this so the internal face is not damaged). Position the rear purling brace so the underside of the brace is flush with the underside of the purlings.
Page 14
Rear Assembly Diagram 14 External You can now fix the brace through the purlings with 50mm screws at the points shown above in diagram 14, mark the purling and pre-drill before fixing. It’s not a good idea to try and screw through the complete sections of glazing bar (unless a countersink is used) as they are likely to split (these are shown below in diagram 15).
Rear Assembly Internal Dia. 14 You will need to measure from the outside edge of the corner bar to get the correct position for Rear Cill the rear base plate. This should be set in 34mm from each end, diagram Use 25mm screws to Rear Base Plate fix this in place.

Front Assembly Internal Dia. 26 Dia. 25 Once you have assembled your gable ends you can fit the aluminium base plates. Do this while the gables are flat on the ground. The front gables are easy to set up as the base plate is fitted flush with the end of the cill which meets the door (diagram 25).
Frame Assembly Before you position your side section onto the dwarf wall you should drill the pilot holes in the bottom of the side corner bars shown in diagram 27. The position of these holes should be about 19mm from the side face and 30mm measured from the bottom end of the bar. You can now position the side section on the aluminium base, you will need a helper to hold this in place or simply strap it to a set of steps.
Page 23
Frame Assembly External Keep faces flush Diagram 28 Diagram 27 Make sure the side corner bar is located correctly and the front face is flush with the end of the eaves bar, mark out the pilot hole positions shown in diagram 29 and 30. Diagram 32 and 33 on the next page show the External Front direction the holes should be drilled in.
Page 24
Frame Assembly Before fixing this corner make sure the inside Diagram 31 faces are all flush (diagram 31). When you are happy that the purling is located correctly (it is normal that the purling is set back slightly from the glass rebate on the front of the building) start by inserting the 80mm screw through the side of the eaves bar into the tenon on the end of the purling.
Page 25
Frame Assembly With help or using props for extra support, position the rear gable on to the dwarf wall and repeat the steps from page 23 to 24. Keep this supported at all times.
Door Installation Your door will arrive already installed in the frame with Diagram 34 the lock and lock plate attached. All you need to do is attach the door handle to install this to the building. Start by sliding the spindle through the top hole in the door (diagram 34), then locate one of the door handles on this and fix with the screws provided.

Page 33
Roof Assembly Now the ridge is in place you can install the roof bars. Slot the bar into the ridge first, the tenon may be a little tight so this might require a tap with a wood or rubber mallet. Once this has located correctly locate the bottom of the bar with the trench in the eaves bar.
Page 34
Roof Assembly With all the roof bars in place drill pilot holes vertically down through the roof bars, refer to diagram 30 (page 23) for the location of this hole. Make sure the roof bars are tight in to the eaves bar on the inside of the building and fix with 100mm screws (diagram 46).
Roof Assembly EV0538M Dia. 48 Internal Now all the roof bars are in place and fully secured you can fit the eaves bracing (EV0537M) and ridge bracing (EV0538M). These are fitted to every roof and side bar in the building. Use 40mm screws to fix these to the building.

Glazing Standard cedar capping or the upgrade aluminium capping? If you have the Aluminium capping you need to slide the glazing NB: Before you start glazing rubber into channels on the back of the capping. Use a Stanley knife check the squarness of the or scissors to cut to length, it is best to use a complete length per greenhouse, installing an side.
Page 39
Glazing Note: All channels in the aluminium capping should have rubber inserted, even if it is going onto the timber. Keep the short flange pointing upwards on the outside. Use the 610 X 153 glass separators between 2 panes of glass and above and The louvre...

Roof Vent Installation Diagram 63 Internal Dia. 64 Now fit your autovents to the slam Diagram 64 rail and to the bottom of the roof vents, diagram 64. Use 19mm screws to secure the top arm of the autovent to the roof vent, do this with the roof vent in the closed position so that you get the bracket in the correct position.
Louvre Glazing If you haven’t already done so you could now install the louvre glass. Make sure the tabs on the glass retainers are pinched slightly they hold the glass tight. Standing on the inside of the building slot the first louvre slat in until it hits the bottom tab of the retainer.
Gutter and Downpipe Installation With help position your gutter Diagram 67 on the side face of the eaves bars, this should be the same length as the eaves bar and fit 25mm Screw between the ends of the roof corner bars. Fix it in place with 25mm screws, diagram 67.
Page 52
Gutter and Downpipe Installation To install the downpipes straight to the floor cut the pipe as per the diagrams below. Use a small amount of silicone at each joint. The brackets can share the same hole as the capping for the panels.
Page 53
Gutter and Downpipe Installation Diagram 71 If you want to connect the pipe to a waterbutt cut the pipe appropriately and simply use the D207 joints to divert the pipe. Its likely you will need to fix the downpipe brackets higher up, again try to use a standard capping screw location.

Finished installation Diagram 78 Internal When you are happy with the final position of your greenhouse and all the sides are vertical and square you can fix the greenhouse to the brickwork using the small ‘L’ shaped brackets (D174M). You can either use the existing 25mm screws that join the aluminium base plate to the timber cills or simply drill new holes in the base plate to fix the bracket elsewhere (you may want to do this to avoid joints in the brickwork etc), diagram 78.
Optional Auto Louvre Installation Once the louvre is installed in the greenhouse you can replace the manual handle with the automatic unit. First of all remove the screw to release the arm (diagram 79). Next Remove the handle from the frame of the louvre (diagram 80).
Page 59
Optional Auto Louvre Installation You now need to mark Diagram 82 the frame to drill the 2 holes, use a 2.5mm drill bit for this. Offer the opener up to the frame with the plates and washers and slide louvre into position.
