36" would be a Charbroiler (CB).
I wouldn't use Traeger pellets in a CB (or ANY pellet machine), that brand of pellets have a lot of ash when they burn and you do burn a lot of pellets in a CB because you're wanting to create a hot grill.
The key is BTU's, how much heat per pellet. the 66% to 100% pellets will give better BTU's. The % is how much hardwood/base wood is there. Traeger uses a lot of lower BTU wood.
Call CS and talk with them. They key will be, for you is sounds, how much will it cost to run.
I don't know the cost of pellets in your location, so CS would be the one to ask for details. They can talk to you about it.
I will say this. I have a new 36" CB, but haven't used it yet, but I do have the Pellet Grill. we LOVE steaks on that because it's 100% wood grilled food.
We'll try to help. If you have more questions, please ask.
