FYI - my makeup air solution
The code for makeup air is not enforced where I live, but I wanted some sort of makeup air for peace of mind. We just couldn't/wouldn't pay for conditioned makeup air. So I lurked around here and some builder forums for any info I could find. This is what I came up with:
(A very quiet 500 CFM duct booster fan controlled by a switch under the cabinet next to the range)
(A motorized damper controlled by same switch)
The ducting is all in the ceiling. The intake is the proper distance from the hood exhaust, and the ducting terminates with an unobtrusive vent cover about 5' from the range. Sure, it doesn't turn on automatically when the hood goes on, but I use it only when the hood is on high.
So that's my $166 solution to the makeup air problem (not including the contractor's time to install the stuff). So far so good!
