I purchased a 48" bluestar range top with a 52" wolf vent liner insert with remote blower 1200 cfm. Since the rangetop is on a outside wall I would like to vent out the wall vs. the roof. I have 10' ceilings. Would I be jeopardizing the suction if I went straight out or do I have to run the vent up the 10' ceiling and then elbow 90 degrees to the outside wall. I get really concerned about roof installation due to weakage issues. Also the vent hood insert is 22" deep is that deep enough or does it have to come out further to capture the high 22K btu front burners.
