Question to Venting Experts

I built a new pipe connection from my stove to the chimney, both are the same length.

The old one had a uphill slant from stove to chimney of approximately 5 inches.

The new pipe has an uphill slant from stove to chimney of approximately 9 inches.

Will the newer connection provide a better draft?

I guess what I am asking is "as slant increases, does draft increase"?

Appreaiet your thoughts.

thanks!

Does a steeper pipe angle from Stove to chimney provide for better draft on a warm day then a less steeped pipe?

A steeper pipe has less resistance so will draft better but the increase would be very slight going from 5 to 9.

Thanks! No pics, sorry!

I'm gonna venture to say that the increased angle may help some but would most likely be un measurable. My reason for this is because the draft or negative pressure if you will, is generated by the warm flue gases rising in the vertical section of your chimney.

Hypothetically you could have a flue pipe exit your stove and angle downward several feet to a chimney and it would draft just fine. Getting the draft started though would be challenging hahaha. Think of it as a siphon only upside down.

Franco's got this less resistance, less angles = increased draft... but in your case it may not even be measurable without some seriously computerized testing gear.
