I bought a Harman P35i for a split-level home where one side of the house is halfway in the ground. I called ion and told them about the smell they said it is "curing" so I left it on the highest temp for longer than 24 hours. I don't think this is the problem. I think the problem is if I close all of my windows and screen door there is a smoke smell being distributed from the distribution fan. My father told me that our second-level pellet stove has an air intake hole that is drilled through the bricks and leads to the outside of the chimney but there isn't one for my bottom level. The fireplace is in the ground since it is a split-level home and I cannot get to the same level as the pellet stove for the air intake compared to the top-level fireplace. Do I need to make the intake for the ground fireplace to be as low as possible? Please look at my crappy picture.

Its a little hard to understand your concern, so brand new stove and install right. Intake air goes through the combustion fan so you shouldn't smell it. If the stove has been burned off, and you are smelling pellets burning inside the house which is pretty easy to distinguish, I would suspect the exhaust vent, perhaps they didn't get it sealed up at the back of the stove or one of the interior connections, those 3-4" adapters if used add a few connections and possible leak source, and another possibility depending on vent type chosen, if using screws to secure connections you must be careful they are not to long and penetrate the inner exhaust pipe, that is a easy way to ruin a pipe and smell smoke and very hard to figure out. Perhaps Combustion blower access panel but unlikely being new. The exhaust smoke would be impossible to see being under pressure but the nose doesn't lie. Could also be the location of your exhaust termination and most houses aren't sealed tight and its getting in.?

the problem is when the pellet stove is burning the distribution fan is distributing some weird smell into my room. When I open the windows in my room and screen door the distribution fan is no longer distributing this weird smell. I do not have an intake hole for air as I do for my envoy pellet stove. Where is the combustion fan getting air from.

It draws air from Your room. Check your heat exchanger tubes for cracks. Silicone all joints on the exhaust vent pipe.
My room is pretty well sealed so where is the next place that the combustion fan will draw air from? Will it draw air from the chimney at the top?

If the chimney install was done properly, no. it should be sealed. If not done right it probably is. Does the chimney liner go all the way to the top with a rain cap?
Yes, it goes all the way to the top. and the cap is sealed with silicone with what I saw. Again when I have the windows and screen door open the distribution fan doesn't have the smell it does with everything closed :/

is this an insert?, either way any stove can be difficult to seal to a liner I assume, I'm not familiar with that transition to make the connection or that type of installation(sounds difficult at best to seal), if your termination is 2 stories up it us unlikely you are pulling smoke in from the termination, and regardless if the window is open or not the intake draws air in from the path of least resistance and smoke out the exhaust pipe, if you are smelling smoke the stove or exhaust is leaking, now perhaps this is exaggerated by the vacuum effect of the intake and pressure from combustion, and the outside air alleviates it accordingly, but the answer is the same, you have a exhaust leak and a few good suggestions to look into and report back your findings, I'd like to see the interior exhaust connections & transitions to help further and understand how they made this connection to the liner, is it a single layer liner, how did they seal off the chimney cavity to interior.

The connection of the flex liner is about the only thing that could be leaking. There is a connector that gets siliconed and screwed to the end of the liner then that gets siliconed and screwed to the take off on the mounting shell. Pretty easy connections if the right connector is used. Maybe they tried to just silicone seal the flex liner to the exhaust stub?

Your stove should slide into a cage. The exhaust pipe is connected to the stationary cage and when you slide it in it will seal to the orange gasket in the back right corner. Make sure the gasket is not crimped ect.

New stove with install. Call them back and have them check the install. Sounds like exhaust piping is leaking and you may be drawing exhaust into the room blower... Watch them if they come again and take pics...

I wonder if they just left the inserts cold air to be drawn from the flue?

Not familiar with the Harmon p35i cold air provisions but you can pull cold air from the far side of the room if you use 3 or 4 inch piping to not restrict cold air.

There is a leak where the flex attaches to the mounting shell. air intake has nothing to do with it. I service probably 50 Harman inserts per year and almost none of them have air hooked up. Usually it is to tough to get a air intake in a standard masonry firebox
