I've just been through it the very bad experience. Ran a Regency classic 3100 l and Accord with the owners manual. After 7 years it has obviously been over fired and cracked. Taking measurements for draft my 30 ft flu had the 3100 at 0.25 to full pegging the meter when running.There was no omission. Customers were chasing a specific draft value for their own particular installation. For example, saying .04 w.c., folks would tune their chimneys to reach this value. And in many, far too many, .04 didn't work! Some paid to reduce chimney draft while others took measures and paid to increase draft. That specific value did not take into account user interface and each unique installation.
Once we implemented the minimum "15'" of chimney length, it help a great deal. Of course their are still cases where the minimum of 15' is still not enough. So for one particular install that comes to mind, 15' did result in .04-.05 w.c." However, when the customer opened the door, there was spillage into the room. So the customer added a 2' section of Class A and the draft changed minimally, but there was no additional spillage.
As I have posted dozens of times, as have any others......"Each installation is unique and your mileage may vary!"
I've got my replacement down to two units The princess insert 29 and the Pacific Energy Summit LE.
A local blaze King dealer has been to the house and looked at the installation. I showed him how I was taking the readings and the spreadsheets of the data showing overdrafting.
Folks in the forum said before taking the 3100 out to run some experiments. So I installed the damper and The damper needed to be fully closed and the holes closed in the damper in order to bring the draft down to some reasonable level 0.1ish at full rolling burn with air choked.
I hesitate to purchase the blaze King because with this much draft now I have another lever to operate, the thermometer, the bypass for the cat, and now a damper. The local dealer mentioned a restrictor plate, but that is not dynamic I might be too restrictive during lighting, or not restrictive enough during full burn.
So I'm really in a pickle what to do appeared leaning to the Pacific Energy just based on the simplicity of the operation and the ash and things won't get into the cat that's the place King has.
On the fence. Any thoughts could be helpful. Local people are really nice guy says he talks to you frequently.
