Silo installers who retrofit your older silo with a ground level opening lid kit are able to install a Silo Vent unit at the same time as renewing your new ground opening lid and cable.
For the D.I.Y., please comply with your state’s OH&S requirements for working with heights, steel, confined spaces and general building construction requirements.
However, if all of the above requirements are met, first remove the silo top opening lid to cut a 300mm hole (depending on the ventilator size purchased) in the centre of the lid. Mould the flashing to the silo lid, with waterproof sealant applied to the underside of the flashing and silo lid. Position and attach tech screws to fasten the unit. Reposition the lid, and it is ready for use.
