Installing a pellet stove - 24' pacific yurt

[MSHAW]

Howdy folks! Wondering if anyone has a recommendation for common wall boot or thimble to vent a Heat Tech 26" free standing pellet stove. We have 3in vent pipe that would be used with the 8in flashing provided by

pacific yurts

. We are hoping that the pipe would have minimal protrusion out of the wall, and minimal support would be needed. Also wondering if a tee is necessary for a pellet? I have been doing research*but can't find the exact parts. Again I know there are many options that can be applied here, but hoping the community might have some intel for first timers!
