Description
Manthorpe GTV CS Castellated Roof Tile Vent Red / Grey / Terracotta Red / Brown
The Manthorpe GTV CS Castellated InLine Tile Ventilator (Brown / Red / Grey / Terracotta Red) is designed to provide a quick and simple solution to the problems of roofspace ventilation and mechanical extraction or soil stack termination through a square topped profile tiled roof.
The low profile vent replaces a single roof tile and maintains an unbroken appearance to the roofline whether used at high or low level, and suits roof tiles from the leading roof tile manufacturers and is available in a range of colours with a textured finish.
The tortured path through the 4mm louvred grill and internal weathering geometry is designed to maintain a 10k m square metres of airflow whilst channelling any water ingress out of the vent and on to the roof covering.
Notes: The tile vent should not be used to extract hot exhaust gases, nor be placed close to other potentially hot elements of the roof structure.
When ventilating at high level, the vent should not be placed on the course directly below the ridge tile.
For mechanical extraction, use the Manthorpe GTV AD Flexi Pipe Adaptor and one of the GRPA Flexible Pipe Range in conjunction with the vent.

Fixing
Application:
1: Prepare the roof tiles in the conventional manner up to the point at which you require the tile ventilator to be positioned
2: Directly below the batten that the vent is to be placed on, mark out a rectangle 170mm x 240mm wide on the underlay in line with the centre of the tile below. Also mark an X in the centre of this rectangle from corner to corner
3: Cut the underlay along the diagonal X lines and fold back the triangular tabs to reveal the spigot opening. Fold the top tab tight up against the batten above it and secure it in position with a staple or tack.
If you are fitting Marley Mendip or Redland Grovebury Interlocking Double Pantiles, proceed to step 4a
If you are fitting Redland Renowns, proceed to step 4b
For all other styles within the range proceed to step 5
Installing Marley Mendips or Redland Groveburys:
4a: When installing the Double Pantile profile tile ventilator onto Marley Mendip or Redland Grovebury tiles, remove the blanking profile tabs visible on the inside of the front face. These areas allow the vent to sit flush onto other double pantile profiles but can be easily trimmed away with a knife to allow the vent to conform to the Mendip/Grovebury profile
Installing Redland Renowns:
4b: When installing the Castellated profile tile ventilator on Redland Renown tiles, the two marked tabs on the front face of the vent should be removed by trimming down the marked channels with a knife allowing the tabs to be snapped off the main body. The removal of these tabs will allow the front face to locate within the profile of the Renown tile
5: Insert the vent into the correct position. Make sure the spigot passes fully through the felt so that it is accessible from the loftspace. Also ensure that the tile fits correctly into the interlock of the adjacent tile
6: Nail the vent down into position by perforating the skins over the preformed holes. Clip the vent in place using the tile manufacturers specified clips for the relavent profile
Once fixed, continue tiling around the vent in the normal manner
