sounds good. Layout the vent on the siding so you can shove the top flange of the vent up underneath the siding for better water shedding. If you have cedar shingles take them off around it and redo up against vent to look neat. Siding a little more diffucult. If you have soffit vent or ridge vent than another vent is probably not necessary. If not 2 would be better.
