CTM

Roof vents (metal)

The CTM roof vent is used for the air outlet or air intake of installations using mechanical ventilation systems: single and double flow, domestic kitchen hoods.

It adapts to practically all tile or slate roofing systems, and ensures a good seal.

For CTM Ø 125 to 160 mm:

Before installation, it is advisable to apply patina oil to the lead plate in order to avoid any dirt on the neighboring tiles.

– Remove the rain cover (1) clipped onto the sleeve.

– Form the sheet of lead (2) so that it conforms to the underlying shape while avoiding the crimping area.

– If it is a tiled roof, it is advisable to add some blocks in the direction of the battens to support the sheet of lead in (A) and (B).

– Install the rain cover with the air flow perpendicular to the slope of the roof (see figure opposite).

Warning: it is important to check the airtightness of the duct/ventilation box and the roof duct/vent.

For CTM Ø 200 to 630 mm:

– Remove the rain cover (1) held by 4 screws (2 screws on CTM 200 – 250 – 315).

– Fix the support plate (3) to the framework using the maximum number of holes provided for this purpose.

– Form the sheet of lead (2) so that it conforms to the underlying shape while avoiding the crimping area.

– Install the rain cover with the air flow perpendicular to the slope of the roof (see figure opposite).

– It is essential to replace and lock the 4 fixing screws.

– Connect the metal sheath (4) to the ventilation duct.

Warning: it is important to check the airtightness of the duct/ventilation box and the roof duct/vent.
