Welcome sopis, be sure to not let that make you cut corners on testing and making sure it is safe.
I almost did not have enough time on my very first build to test it long enough before installing due to the incredible need for heat, we were living in our motor home at the time and winter was only a few weeks away!
I finished it and got it in the day we had a first light snow.
Too much pressure, always do a good deal of testing, never use something like this with pellets unattended, or even sticks unattended.
There is too much that can go wrong and cause back drafts, and smoke to fill the living quarters.
Ask me how I know, as well bigalow farms.
