1. Select Circular in the Categories drop-down list and then Roof Cowl in the Available Type drop-down list to display the Circular Cowl window:

   

2. You are required to input the following dimensions:

   • Duct Diameter

   • Cowl Diameter

   • Cowl Height

   • Duct to Cone

3. To visualize how the dimensions equate to the actual piece of HVAC, click Picture to display a detailed drawing for Circular Weather Cowl (CAC).

   Note: The fields will be pre-populated with default dimension. These dimension are governed by the details defined in the HVAC Catalogue.

4. Specify a type of joint to use for the Arrive Joint. Refer to Create/Modify HVAC Component for a detailed description.

5. In the Position list, select Connect or Unchanged:

   • Click Connect (default when Create is selected) - connects the piece of HVAC to the previous one.

   • Click Unchanged (default when Modify is selected) - positions the component at the co-ordinates 0.00.

     Note: Unchanged is usually used, when Modify is selected, it does not connect the component but positions it at 0.00, in effect in a floating position.

6. Click Defaults to reset all the fields back to when the Roof Cowl window was opened.

7. Click Fit to orientate the Roof Cowl to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.
