Harman P61A. Stove pipe size? Odd....

[Cory S]

Going to be installing my P61A soon, and I am gathering install items. I THOUGHT 3" double wall pipe was what the normal pipe used is.

The iron exhaust outlet on the back of the P61A measures just a titch under 3.5" OD......So I assume 4" double wall pipe is what I need? I am looking at the Duravent piping pieces and adapter from Home Depot.

Does the Duravent 4" pipe have closer to a 3.5" inside diameter due to the double wall? If so, I guess thats why the P61A outlet is close to 3.5" OD....

You can use either 3" or 4". How far do you have to go?

3" pellet pipe, duravent in my case, no adapter, just pipe with orange RTV directly on the cast iron exhaust cone.

You'll need a connector piece for attaching to the stove - even my Hastings needed one. You can buy one for either the 3" or 4" double wall pipe (3" is the standard unless you have a lot of elevation or horizontal). The 3" aren't all that expensive on Amazon (just got one for my baby Harman): http://www.amazon.com/gp/product/B00EUVVSS8?psc=1&redirect=true&ref_=od_aui_detailpages00

As Bogieb states. Get the adapter and I would run 3" if you can. It's cheaper. Duravent is fine. Look online for deals. Good luck and let me tell you that you will like that Harman P61. Great stove!
