Does a round stainless steel liner require a rain cap?

[clesnick]

Hi.

I am planning to install a 5" round stainless steel liner in my chimney for my wood stove.

I don't want to use a rain cap if I don't have to because of the way it would look on my house. Are rain caps necessary with a metal liner?

The clay liner has been open to the rain for decades and we haven't had any problem with water. I'm not sure how using a round metal liner will change that.

Thanks for your help!

The masonry chimney usually has a sump (small pit filled with rubble) in the bottom of it into which the water falls.
A stainless liner would be more sealed and therefore should have some sort of rain cap.

In terms of style, there is a lot you can do to make it look better than the normal liner rain caps. You can use a regular masonry chimney cap and terminate the ss below it. If you don't like the style of the standard chimney caps, I have some semi-custom stuff in the shop which may be able to help you. If you have interest let me know the size of the flue tile.

Examples enclosed.

Yeah. Not putting a cap on it would turn the liner into a five inch diameter rain gauge. Right into the stove or tee.

Birds, bats, etc., too.
