Greetings,
Currently I'm finishing up a kitchen remodel, tying up the loose ends.
I was able to source a new JennAir 600cfm hood for a great price. The OEM flap vent that attaches directly to the top of the hood provides a 10" x 3.25", I found this to be available at the local Home Improvement store:
3.25-in x 10-in x 7-in Galvanized Steel Straight Stack Duct Boot
The offset will work well for me, there is a ceiling joist almost directly over the hood, this should allow for an easy install straight up through the ceiling.
My question: This provides for 7" ducting. I'll be using 5' lengths of galvanized steel round duct. The run to outside, if I install this as I'm thinking, will be close to 30' through an unheated attic area (mid 1950's ranch, central New England) and exiting out the side of the house. There would be a single 90 degree involved. Will I want to keep the 7" size for the entire run, or could I go down to 6", or smaller. Looking for advice for best operation of the hood, not so much trying to save dollars.
Many thanks in advance for the advice.
