Help.
I have just had a 36" Cavaliere Island hood installed at 36" above my BlueStar 30" cook top. My contractor has placed the chimney covers upside down. In other words, the louver vents which should be at the ceiling end of the chimney are at the hood end. The unit is being vented directly through the roof (not recirculated). Will this make any difference to the efficiency/safety of the appliance? It is 950cfm with baffle filters.
I was not present for the installation and only noticed it after the fact.
