They've we planned to buy our 36" Bluestar range from had told us we only need a 36" hood with a600 CFM blower. I know they say to go 6" wider than your range, but the appliance place said that since we will have 6 burners and no grill or griddle, then 36" was fine.
But after reading the range instructions, DH has decided we should just get the 42" hood. We have a very open floor plan and DH doesn't like the house to smell. We think we will stick to 600 CFMs though,but were wondering how easy it is to switch the blower if we decide we need to upgrade to 1200 down the line.
