Wow, I know I should read the fine print, but that's some fine print!If you click on the Contact tab at the top of the Piazzetta.com home page, read the fine print underneath the message box. Outside of that, all warranty processing and tech. support is done through Pacific Energy. Pacific Energy is not manufacturing the stoves, they are 100% Piazzetta product. P.E. is helping with importing/distribution and dealer support which is why you won't see their name in plain site on the Piazzetta site.
Interesting. That's quite a difference! Do the european models run with the same air/fuel ratios?Regarding the air wash- As it was explained to me directly from Piazzetta's North American rep., the air/fuel ratio for Piazzetta stoves is 9 parts air to 1 part fuel as opposed to most other stoves which are in the neighborhood of 35:1. Because of this, the air directed across the glass for the air wash is reduced. This is one reason why the efficiency rating on these stoves start at 85% and head north from there. My justification is if I am benefitting from more "net" btu's being transferred to my house, I am ok with wiping the glass a little more often.

Thanks for the tip. My exhaust flue temps are usually around:I'm not sure about that, I would imagine most of the European models similar in design and efficiency would follow suit but I can't say for sure. That's the nice thing about having a stove with an exhaust probe sensor, lower flue gas temps means more heat transfer to the rooms unless you're burning a low btu content pellet. My flue gas temps range between 230 - 275 deg. F., anything less than 212 and you can start running into condensation issues.
What a Beauty.....
Thanks for the tip. My exhaust flue temps are usually around:
230 degrees for feed rate 3
240 to 250 degrees for feed rates 4 and 5
205 to 215 for feed rates 1 and 2.
I've upped the room blower for for feed rates 3, 4 and 5 to 38, the max, which presumably lowers the exhaust flue temp a little. Likewise I've upped the room blower for feed rates 1 and 2 to 36 and 37, respectively, which are higher than the OEM setting of 34 and 35. Do you think I should lower them back to raise my exhaust temps a hair?
Any other setting recs?
Again, thanks so much for all your comments!All the Piazzetta stoves are set up that they can be calibrated with a magnahelic gauge- If you have already made changes to the stoves settings, I assume you have the codes to access the menu parameters screen. There is a brass acorn nut threaded onto a port on the back of your stove above the power cord, this is where you would attach the tubing on your mag. There are factory recommended vacuum readings for each power level, you would adjust your smoke fan rpms to meet those benchmarks. In my experience, if you are burning hardwood pellets, I have found calibrating the vacuum for approx. .02- .03" W.C. above factory recommendation helps prevent build up in the firepot. I just attended the HPBA expo in Salt Lake city and I saw an updated firepot Piazzetta is offering for the larger units (Sabrina, Sveva, P96 series). Its has a stainless steel deflector bolted to the back of the firepot underneath the auger tube, apparently to increase the venture effect in the firepot and help eject the ash. The target vacuum settings for the Sabrina are as follows- power 1 (18P) .24" W.C., power 2 (19P) .26" W.C., power 3 (20P) .30"W.C., power 4 (21P) .34" W.C., power 5 (22P) .38" W.C. Again, this is the factory recommendation, these stoves are operated almost exclusively with softwood pellets in Europe so results will vary when dealing with hardwoods.
