VC Encore 2 in 1 used as fireplace(doors open)

I recently installed a VC encore 2 in 1 in my home. It has a 6" pipe that goes into a sleeve in a chimney through the center of the house. A few months ago we were doing major renovations to the house and we were down to bare studs. I could run the stove perfectly fine with the doors open with no smoke coming out. After insulation and drywall went in the stove seems to not breathe as well and smoke a little when the doors are open. I open windows to try to help with the draft but whether they are open or not it still smokes. The house isn't particularly tight now because the renovation was only one large room. We live in an old farm house so there are plenty of places for air to come in.

I'm looking for any suggestions to help with the small amounts of smoke that escape when im burning with the doors open and screen in. Thanks!

Have you cleaned the flue recently? That's the place to start.

Last I checked, you aren't suppose to run the Encore with the doors open while using a 6" pipe. 8" pipe is required if you plan on using the the stove in "fireplace" mode.

I know they say fireplace mode won't work with a 6" pipe but it was working before..... I'm looking for any suggestions to make it work with the 6" pipe.

It won't consistently and goes against manual recommendations.

It will work sometimes and not other times. Also, as the fire dies down, the draft will diminish making it an even worse idea, and dangerous to your health, to run the Encore with the doors open with a 6" pipe.

Don't do it.

If you want to run the stove with the doors open, use 8" pipe.

+1 on the 8" pipe if you wish to run it with open doors
