I would say under most conditions, you would never have fumes in the house.
But... In my installation I detected a faint sulfur smell in the house. It turned out that my exhaust was being drawn back into the fresh air intake. From there, the combustion blower leaked enough of that "smelly" air to get noticed in the house.
I think under normal circumstances this would not happen often enough to get noticed. As usual, my install was not normal. My stove is in the basement and the vent is located between a walk out bay window and a stoop. Exhaust gases were pooling by the combustion air intake.
I did two things to solve my problem.
Plugged the bottom of my vent tee with a cap ( actually I used my wife's smallest mixing bowl - fit almost too well) - this immediately stopped the smell.
The second thing I did was to seal the combustion blower mounting flange to the stove body with high temp silicone. ( blower mounts with two bolts, 5 min job)
The interesting thing is that I almost think Harman wants you to smell it if exhaust is being drawn into the intake. There is a round 1/8" hole on the combustion blower housing that I sealed as well.
I just got my DVC-500 (after waiting for it for 8 months
). After a successful and easy install, I too, smell a little smoke. But I'm just "testing" the pot with a couple handfulls of wood pellets. Not sure if that makes a difference, but I don't think it should. One thing the dealer told me was I did not need all of the external stove pipe shown in the instructions, just a vent cap. So I installed the horizontal vent cap from DuraVent, directly to the Harmoan Termination. I will take your advise on sealing the conbustion blower housing, and if I still smell any smoke during more 'tests', I will definately install the external vent pipe as per the instructions, with the "T", then straight pipe, then 90, then the cap I just bought. Thanks for the info.
