This is a copy of our Lean-To greenhouse base plan. Dimensions shown are allexternal and allow for a small overhang, (as shown in the diagram at the foot ofthe page) suitable for brick or concrete perimeter bases.

Lean-To Greenhouse Base Plan

It would be useful to read at least the following introduction before attempting toassemble any parts. Please read each section fully before commencing each stage.

It is not possible to erect this Lean-To alone, it is therefore essential that you havean assistant throughout.

Please note that all Lean-To’s of 24ft. or more in length must be bolted down to acontinuous concrete base or strip foundation.

Parts Identification

All the way through these instructions end profile identification charts (I.D. Chart)are on each page for your reference so that you can identify the parts, it is notadvisable to mix parts from various boxes especially when extensions are involved.

ASSEMBLY OF ROOF, FRONT & ENDSNOTE: IDENTIFICATION OF ALL PARTSAND SECTIONS CAN BE FOUND ON THE IDCHARTS (PAGES 14 – 16).THE ROOF

1 Identify the ridge member (no.1 on ID chart), roofglazing bars (No. 2 ID chart), roof end glazing bars (No.3) and the eaves gutter (No. 4 ID chart). For help withidentification, roof glazing bars are the same length asroof end glazing bars.

2 Thread PVC glazing strip (No. 5 ID chart) into thegrooves provided on the roof glazing bars and theinside groove only of the roof end bars. Cut to fulllength taking care not to stretch the PVC strip. A littlewater or washing up liquid used as a lubricant mayhelp; especially in winter months.

3 Lay out the parts roughly in position with PVC stripfacing upwards.

NOTE: If fitting an extension please referto page 13.

4. Insert short square headed bolts (No. 6 ID chart) intothe holes provided in the ridge member and looselyfit nuts.

5. Slide glazing bars and roof end glazing bars onto boltheads and push home fully. Tighten nuts securelytaking care not to over tighten.

6. Fit apex plate (No. 7, ID chart) to both ends as shownand tighten securely.

7. Slide short bolts into opposite ends of roof glazing barsand roof end glazing bars.

8. Offer up eaves gutter to bolts and, taking care to pushfully home, tighten securely both roof glazing bars androof end glazing bars.

FIXING FRAME TO THE WALL AND SECURINGTHE BASE

The complete frame can now be positioned on itsfinal site and fixed to the wall.

24. Butt completed frame tightly against wall and markexact vertical position for long glazing bar on wall. Itis important at this stage that a spirit level should beused to ensure frame is level and square.

25. Holding the plain end bar in its vertical position,check with spirit level, drill through the centre of thebar with a 5mm twist drill ensuring that this holelines up with the centre of a brick, not mortar andcontinues into wall to mark position of hole. Fourholes should be made in this way equally spacedstarting 6” / 13.5cm from the top and bottom.

26. Pull frame away from wall and fir Sealband stripprovided. Cut strip to required lengths, leave a smallgap at each hole to allow screws to pass through.Remove backing paper from strips and fit betweenholes.

27. Now drill the wall with 8mm masonry drill, at thepoints marked, to at least the depth of the roundheaded screws. Fit rawplugs supplied.

28. Repeat stages 24 to 27 for long glazing bar at otherend. Position frame against the wall loosely fittingscrews through the wall glazing bars into therawplugs.

29. To fix ridge to wall drill 5mm holes top and bottomcentrally between each glazing bar.

NOTE: A small V groove is provided the length of theridge to locate your drill tip. continue drilling slightlyinto the wall to mark position.

30. Remove loosely fitted end glazing bar screws, pullframe with ridge away from wall to enable you todrill all holes marked for the ridge with an 8mmmasonry drill (to at least the depth of the screwsprovided). Fit rawplugs. At this stage it isrecommended that the base be secured.

31. Ensure that the frame is square and that the site islevel.

32. Identify the base anchors (No.15, I.D. Chart) or basebrackets (No.15a, I.D. Chart) and lay out at the baseof each glazing bar on the ends and every otherglazing bar on the front. (Only one anchor requiredat each corner - not two.)

33. Dig out a hole below each glazing bar 6”x6”x12”deep and secure base anchors to bolts as shown.

34. Screw both the long glazing bars and the ridge tothe wall

35. Now concrete in each anchor and allow to set.

GLAZING THE ROOFNOTE: The roof glass is over-lapped

NOTE: All bar caps are factory cut to lengthsrequired. Having positioned bottom cap, taphead of bottom screw to ensure it engages in thecorrect position.

36. With reference to the glazing plan identify roof glassand PVC corner bar capping (No.16 I.D. Chart).Secure in position shown using self tapping screws

(No.17 I.D.Chart). Note that the bar capping, whenbutted up against the gutter, will stop short of theglass. This is to allow the next row of sheets tooverlap.

Continue fitting first sheets to each bay usingstandard PVC bar capping (No.18 I.D. Chart) forintermediate roof glazing bars and corner cappingat the opposite end.

ASSEMBLING THE VENT37. Identify the vent kit(s) and assemble with a standard

size pane of glass (610 x 610mm). Do not at thisstage attach the slam rail assembly, this will beattached when the roof glazing is complete.

38. Fit both side vent members to vent hinge, usingM6 x 10 bolts. Slide glass into side vents and intohingeThen fit cill member in place and fix using M6 X 10bolts. Finally, using No. 8 X 12 self tapping screws, fixat each corner, ensuring the vent hinge closures are inplace.

On all models use silicone around the perimeter of theglass to seal any gaps, checking first that the vent issquare.

NOTE: See separate instruction leaflet in openerbox.

39. At this stage, slide first a vent stop (No.22 I.D.Chart), then the assembled vent, followed by afurther vent stop, into the groove provided in theridge. Do not secure at this stage.

NOTE: If you are fitting more than one vent per side,slide all vent stops and vents in at this stage.

40. Decide on the position for the vent(s) and secure alltop sheets up to the vent aperture. All top sheetsshould be pushed into the ridge member. Fit barcap covers after securing top sheets.

41. Position vent over aperture, slide vent stops up eachside and secure both stops firmly.

42. Identify the slam rail (from vent kit) and slide thebrush strip along its length, protruding each end byapproximately 5mm. Then using standard M6 X 10

bolts and nuts attach the fixing cleats (No. 27, IDChart). Next identify 2 cropped head bolts (No. 25,ID Chart) and ensuring that they are located into theglazing bars on either side of the vent, slide raildown onto edge of glass, tighten nuts to secure.

NOTE: See separate instruction leafletin opener box for full details.

GLAZING THE FRONTNOTE: Glass on the front is butt jointed usingseparator strips

43. With reference to the glazing plan identify glassbase panels, PVC standard and corner bar cappings(No. 16 / 18, ID Chart), black or white separatorstrips for glass (No 26 ID Chart). Bar cappings will beshorter than front glazing bars by 16mm.

44. Starting from one corner, position first base panelfitted with 4mm white or black separator strip.

Select corner bar capping and secure with bottomself tapping screws (No.17, ID Chart) only at thisstage.

45. Continue fitting the base panels finishing the rowwith another bar capping.

46. With reference to the glazing plan fit the first full rowof small glass sheets complete with separator stripand secure with further self tapping screws.

47. Secure panes in position one side only by screwingall self tapping screws into the bar capping and fitbar cap covers (18a I.D. Chart)

48. Repeat instructions 47 until side glazing is complete,finishing the side with a further corner bar capping.

GLAZING THE PLAIN END49. Locate and roughly lay out corner bar cappings and

standard cappings. Corner caps are used against thewall.

50. Following established procedure, fit all base panelsand all glass panes up to (but not including) the topangled sheets and secure as work proceeds.

51. With reference to the glazing plan, identify the topangled sheets and fit by pushing up into the roofend bar recess, and align bottom edge withseparator strip allowing glass to drop in. Secure allbar cappings.
