Why has the cowl not got a rain cap?

The Pyroclassic eco flue system and full flow vertical discharge cowl has been in use now for more than 20 years.

The cowl is designed to work with the fire in creating a good draw whilst not inhibiting the flow of the flue gases from the cowl. The design and shape of the cowl ensures that no significant amount of rain water can enter the flue system.

Many customers mistake the full flow cowl as the end of the flue pipe and often question whether something is missing from the cowl assembly when in fact this is the complete unit as it has no raincap or butterfly arrangement and is a straight pipe.
