Hello, fellow pellet stove owners.
I went thru many pages on this forum, but haven't seen an answer to my question (at least not complete answer).
I have paid for the installer to put in the stove for me (I've build my own hearth to pellet stove specifications). He used a 45degree elbow and attached a 2ft DuraVent pipe to it and ran it straight thru a wall, with an angled end cap. Combustion air pipe, he said, doesn't have to draw air from outside, since the house is old and drafty.
3 Weekends ago I fired up the stove. No leaks at pipe joints inside the house, none outside. Stove fired up fine, but then immediately started to emit some bad odor, as if plastic/paint was burning. I ran it for an hour in thermostat mode and had to shut it down and open all the windows in the house.
Last weekend, I've installed a T-cap, 3ft of vertical pipe, 90degree elbow and the same end cap (see pictures). Resealed every joint inside, outside the house with High Temp silicone (red). Waited 1 week for everything to cure.
Finally, last weekend, fired her up again. No leaks whatsoever, but the same bad odor (no smoke, just smells like burnt paint or plastic). I couldn't keep it overnight, so we wouldn't get CO2 poisoning. I fired her up with 3 open windows early in the morning, again, and we left for 4-6 hours. When we came back home, boy, it was HOT. Same smell, not as strong. but the glass was covered with black soot. I shut it down, let it cool off. Then thoroughly cleaned fire pot, walls, glass. All were covered with black soot.
Is this smell normal? Why black soot only after 5 hours of using the stove in thermostat mode on lowest blower settings?
Very concerned.
Thank you
