Before purchasing a replacement piston firstly check that piston rod is located in the hole in the top block.
The rod is designed to disengage in windy conditions and may need to be reset manually. If the piston has stopped working you may be able the slide the piston assembly out from the bottom block by loosening the m6 bolt in the block.
Earlier models prior to 2007 have a smaller diameter hole in the bottom block that will not allow the piston assembly to be withdrawn. In this case a new complete ridge autovent will need to be purchased.
If the placement of your piston is correct and is still not working the piston will need to be replaced. These are available to purchase for £20 each. As the pistons are filled with an organic wax compound there is no specific expiry date however we do offer a 2 year warranty.
If you are unsure as to whether or not you need a replacement piston please feel free to call us on 01242 662926. One of our team will be happy yo assist you.
Circa. 2006 Bayliss changed the design of their ventilation system so that the piston can be removed, making the mechanism much simpler and more cost effective to maintain. I you purchased your greenhouse before this time then you will probably need this mechanism to replace the old.
This can be easily figured out by loosening the M6 bolt on the lower fixing block. If the piston can be easily slid out then you have the new design and only need to purchase the replacement piston.
If your piston cannot be removed because the fixing block is too tight around the piston, then you have an old style mechanism and need to replace it with this new design.
Our unique full length ridge ventilation of our structures has been designed to work specifically with the Bayliss automatic opening system.
They require no electricity to operate relying simply on the contraction and expansion of wax to open and close the greenhouse vents. The warmth of the greenhouse interior causes the wax to expand and push the vent open. Similarly as the greenhouse cools the wax contracts and vents close.
All our greenhouses have these fitted to the ridge vents as standard. The autovents will operate efficiently for a number of years but, like any moving part, will need replacing over the extensive life of the greenhouse. Such an important greenhouse accessory is held in stock and are simple to replace.
If you are unsure as to which vent you have, please get in touch with us. One of our team will be happy to help.
MK7 autovents are used as standard in the roof opening lights in our glasshouse range.
You may also choose to install autovents to the side windows of your greenhouse using the Bayliss triple sprung Mk7 autovent.
Measuring approximately 12 inches (30cm) in length the MK7 can lift a vent weighing up to six kilos. At full stretch on a hot day the autovent will give a maximum opening of approximately 12 inches ensuring good air flow around the greenhouse – especially if used in conjunction with our unique ridge ventilation.
We provide stainless steel fixings and a cedar block with the autovent to ensure that it is correctly mounted to a Gabriel Ash greenhouse.
Please give consideration as to the positioning of the autovent in relation to any greenhouse staging or greenhouse shelving. It is often best to place such autovents on the opposite side of the greenhouse to the staging or shelving in order to avoid complications.

Easy to operate, our greenhouse roller blinds are made from a green hard wearing synthetic material that is well suited to a greenhouse environment.
Designed specifically for our greenhouses, the roller blind is mounted and secured to the generous cedar framework of our structures and offer 60 percent shade, helping to prevent the greenhouse, plants and user from getting too hot in the warmer summer months.
These blinds are fitted internally and operate on a spring loaded roller allowing greater control of the temperature in your greenhouse.
