So after lots of fighting with a existing flue, and liners, and crappy walls we finally finished the install of our new 55-SHP10L today. We ran it on high for awhile as people suggested to get rid of the smell, and have since turned it down. It is still putting out plenty of heat, but when facing the stove, the vent on the top left blows hot and strong, while the right top vent blows very weakly and a bit cooler. Is this normal? Could I have something blocking the vent somehow? Thanks.
