Roof cowl CTM 200 (metal) colour tuile (roof tile)





The CTM roof cowl is used on air intakes or discharges in installations using forced ventilation, notably controlled single and dual flowrate systems, air conditioning systems, or domestic kitchen hoods.

 

It can be used on practically every type of tile or slate roof covering and provides excellent weather-tightness.

  

- Remove the weather cowl  held by 4 screws (2 screws on CTM 200 / 250 / 315 models).

- Fasten the support plate  to the frame using a maximum number of holes provided for this purpose.

- Shape the lead sheet by moulding it to the reliefs while avoiding the crimped edges.


- Install the weather cowl with the airflow perpendicular to the roof slope (see figure opposite).


- important: refit and lock the four fastening screws.

- Connect the metal sheath to the  ventilation duct.
