8ft Wide “Poly-Pitch” Assembly Instructions Work Safely When you tackle a job it is important to work safely. Please consider the following points when building your Polytunnel.  Keep your work area tidy. A tidy site is a safe site.
Page 4 8ft Wide “Poly-Pitch” Assembly Instructions Slot the Foundation Tubes into the concrete, to the outside of the string lines. Make sure the Foundation Tubes are vertical, touching the string line and spaced at 5ft centres. The Foundation Tubes should be protruding above ground by approximately 35cm.

Please note the orientation of the fittings. Tip! If you have ordered crop/tie bars, it’s easier to put the KH25 fittings onto the inner hoops now.
Page 8 8ft Wide “Poly-Pitch” Assembly Instructions The A20 fitting is slotted over each foundation tube for the hoop to rest on. Set the A20 fittings on the end foundation tubes so that they are level across the width of the ‘tunnel and approximately 5cm above top of the base rail.

Page 26: Polytunnel Maintenance
8ft Wide “Poly-Pitch” Assembly Instructions POLYTUNNEL MAINTENENCE Your polytunnel should require very little maintenance during normal use. 1. “Moving” parts of your polytunnel are the most susceptible to damage from extreme weather conditions. These include items like doors and roll up curtains. To minimise the likelihood of damage, ensure that the doors and curtains are operating correctly and adjust where necessary.
