Our Zephyr Cyclone range hood is now installed. No assistants were needed. The trick was to screw and tape the 3.25 x 10 to 6" round adapter pipe to the new hood so that when lifted into position the pipe pokes through the wall and supports most of the hood weight. By holding the front of the hood up to the cabinet bottom the 1" electrical shielded electrical cable access hole and the four support screw holes were marked. Using a 9" drill bit extender I was able drill the the support holes with the hood in place. The hood was functioning by the time dinner needed to be cooked. DW's only critical comment was that the two 40 watt lamps were too bright on the high setting. They are not recessed enough to be completely shielded by the hood for shorter folks, so they become a glare source. A PAR 20 50W halogen lamp also works in the hood fixtures but sticks out about an inch rather than being almost flush like the 40 watt non-halogen bulbs supplied with the hood. To finish tomorrow I will install a new Broan exterior duct cap with damper. There is an impressive outflow of air at all three fan speeds as felt from the outside vent opening. The lower two speeds should be adequate for nearly all cooking activities and the noise is acceptable. If we had billowing smoke then the 650CFM third speed would be welcome. The prior hood was rated 180CFM and was very loud at anything beyond the minimum speed. This black hood looks great with our new black Electrolux slide-in range. The 22.5 inch hood depth matches the 22" maximum front burner distance from the back wall.

Manufacturer's preference primarily. Microwaves (even ones combined with a kitchen fan) are "expendable" consumer items and tend to be cord-and-plug connected. Hoods and regular stoves/ranges tend to be "fixtures" and hardwired, but that's not a rule.

Whether or not the bathroom lighting circuit is legitimate to tap in to depends one whether it also feeds the receptacles in the bathroom. The receptacle circuits are not allowed to have non bathroom loads on it. You need to read the installation instructions on the hood to see if it requires it's own circuit.

Hi everyone. Been reading a lot on this site and got tons of good info. Just purchased and installed a Best by Broan 48 inch range hood with external 1200 cfm blower. Used rigid duct, Fantec silencer, one 45 degree bend, one 90 degree and a total physical length of 13 feet - calculated at maybe 25 feet. Hood is super quiet - basically you can not hear anything until until about mid speeds (variable adjustement) and max speed is mostly lots of air rushing thru the baffles - lots of air. Question - how do I know if the hood blower is working properly. For example I don't feel lots of air being drawn in down below the baffles. Air is felt about 6 inches below the baffles and a sheet of paper will stick to the baffles as others stated for a test. Should the air being drawn in be felt lower or is this about normal. I also had a window open when testing. How much below the baffles should I feel air being drawn in when on full speed Thanks
