Installing the STUDOR® MAXI-VENT™

The MAXI-VENT™ is suitable for internal or external installation. (* see note below)

In images 1 & 2, an external vent pipe, which previously protruded through the roof, has been cut down below eave height and has been fitted with a MAXI-VENT™ and the optional aluminium cover.

In image 3, a MAXI-VENT™ has been installed internally, terminating the vent pipe within the loft space and avoiding the need to penetrate the roof.

* N.B. The current UK BBA certificate only mentions internal use. However, many Building Control Officers agree that the EN12380 A1 rated operating temperature range of the Studor MAXI-VENT™ (-20C to +60C) make it suitable for outdoor use and have passed it for external use on that basis. Please check with your local Inspector before ordering.

There is only one model of MAXI-VENT™ which can be adapted to fit most common pipe sizes as shown in the following diagrams. Determine the size of your pipe and select the appropriate button below - a window will open up to show you what components are necessary to adapt the device to your pipe. These components are available at most DIY stores and cost just a few euros.

Pipe diameter markings The easiest way to determine pipe size is to read the lettering printed vertically on the pipe. The "DN" number will tell you what the External Diameter is. If this is not possible use a ruler, taking care to avoid parallax error.
Installation Hints
  1. Lubricate the rubber gaiter with washing-up liquid to make it easier to insert.
  2. If installing in a loft space the polystyrene packaging can be used as a cover to provide heat insulation.
