I am planning to install my new Harman Accentra insert myself withing the next week and would like to know if anyone out there has done this for themselves. I have never installed a stove by myself, but I consider myself fairly handy. I purchased the Harman Zero Clearance cabinet, so I feel that it is safe to install the unit into my frame fireplace "bump-out" that my gas insert sat in. My main concern is obviously getting the venting right. I'd appreciate recommendations on what brands of pipe are good, or at least easy to work with. Any other tricks or helpful hints would also be appreciated. Thanks!
