Hi there, I assume that you are a new Piazzetta owner, at this moment if you are on this forum it usually because you need help with your new stove, I would like to introduce myself, my name is Pascal Maertens I’m from Mont-Laurier, Quebec in Canada I’m also a certified Piazzetta technician. I have been selling Piazzetta products for now five years and since then owned too stove, one was a Sabrina and recently bought a P962 only for the look of it, and believe me, at first I had my share of problem too but today Piazzetta stove have no secret for me. Here are my recommendations if you own a Piazzetta; The less you have chimney the less it cost and the less you have problem First have it adjusted with the proper tools to the proper settings by a technician Always run your stove with the type of pellets you made your settings with soft of hard wood Have your stove and chimney totally cleaned every 2000 to 2400 pounds of pellets In winter run on power level P3 and more then adjust the temperature with thermostat Energy saver mode in fall and spring time only unless you have a very well insulated house OAK or no OAK I don’t care it’s your money but be aware in some states there’s laws on this but this stove is fully adjustable so it dosent really need it It is also possible to run a Piazzetta on solar panel and minimize the effect on batteries Please, note that for all of these recommendations, I made a little explanation text below, that I hope, will help you out, but don’t forget I’m also there if you need further professional assistance or have any other issue that would not be covered by this document. Now before you go out there looking for answers please read this A to Z help guide that I have built after many e-mail and post that I have exchange in the past years in Canada, Europe and in the states. I do not represent Piazzetta opinion; this document is made as an individual interest in the product, and in accordance with my ready to lend a hand, way of life. And like many other member on this forum, I do not get paid for this. Cleaning the stove properly First thing I would ask you to do, if you have burn at least 2000 pounds of pellets or if you have any black soot problem on your door window. If not got to ( 2.) You should clean your stove, simply clean the complete air channel step by step, starting with the oak entrance, then the stove grate in and under it, the back of baffle and also disconnect the chimney and clean inside the exhaust careful there is an impeller in there, the chimney itself should also be cleaned. If the prior adjustments have been correctly done most of the time this simple cleaning should do the job and everything should be fine, if not let me know. For your own information this cleaning operation is needed after a certain time. After 2000 to 2400 pounds if installed on 3’’ chimney if not it caused a lack of air and will result in a large lazy flame, an accumulation of black soot on the door window that can also end up on the outside walls like on this picture below Figure 1 Mont Vernon on this picture the chimney installation is a little too low, but it was only to show you the soot cause by a lack of air, this wall has been cleaned with a pressure washer and still shows trace of soot from a none adjustable stove.
