So getting ready to install my stove I figured the 3" pipe would slide easily into the thimble. Not happening, It is so tight I feel like I will need to hammer it thru? Is this normal?
 
I have not run into that. I don't think it is normal with a standard thimble. Does it have a donut gasket ? I see some thimbles now include a gasket to tighten up the usually loose fit. Just my two pennies.
 
Are they the same Manufacturer? Pellet vent pipe, through Excel thimble?
 
When i installed my pellet vent pro piping the outside diameter of the piping was 3.625 inches and the thimble was 3.75 inches so there was a small gap that was easily caulked.
