GFS plus
GFS PLUS is the original pipe-in-pipe, pre-sleeved CSST solution available in the UK. This innovative pre-sleeved CSST system means you don’t have to sleeve your CSST on-site.
GFS PLUS is designed to create a gas safe, easy to install end-to-end gas connection. It will typically save an installer 70% installation time against rigid pipe and traditional plumbing materials.
The flexible piping system can bend during installation around obstructions.
BS6891 (8.7) states:
- Pipework passing through a wall or a floor, whether or not it contains a cavity, shall pass through a sleeve
- No sleeve shall have joints along its length
- Any sleeve shall pass through the full width of the wall or the full thickness of the floor. The outside of the sleeve shall be secured and sealed at each end to the structure of the building with a suitable building material, e.g. cement mortar or flexible sealant
NOTE: The internal diameter of any sleeve should allow for an annular space around the pipework to enable satisfactory insertion and withdrawal of the pipework and allow adequate sealing between the pipework and the sleeve.
GFS PLUS
Complies with BS6891 installation requirements
Support
When installing GFS PLUS vertically in unventilated areas you should support GFS CSST, not from the sleeve, but before and after the unventilated area on the CSST pipe. In the unventilated area you should clip GFS PLUS from the sleeve.
Cost Effective
Removes the need to pre-sleeve CSST pipe. This saves valuable installation time on site, a real time saver.
