This article explains installing the kitchen range hood vent, not wiring it. Consult the manufacturer’s instructions and the local electrical building code to determine the proper wiring method for the unit. In the building code, it may be listed under “duct systems”.
This type of exhaust fan removes cooking odors, smoke, and air-borne grease from the kitchen in the same fashion that a bathroom exhaust fan removes moisture.
Planning the Duct Installation
The first thing to determine is if it makes more sense to route the exhaust through the roof or through the wall on the side of the home. On brick veneer homes, exhausting through the roof may be the only choice.
Another consideration is the length of the duct. It’s a good idea to use as few elbows as possible and the shortest length of duct as possible.
Installing Straight through the Wall to the Exterior
First, be sure there’s nothing in the way that would make this method impossible. For example, are there plumbing pipes in the way? If there is anything attached to the exterior of the home directly opposite the hood, see the round duct installation below. Then, the duct can be routed higher up the siding.
If a straight shot is possible, the process will be easier. First, the range vent hood should have a knock-out panel on the rear. Remove this. Next, determine exactly where the hole in the wall should be cut out.
Use the rectangular damper as a template to mark the wall. Before actually cutting the wall, hold the unit in place to ensure the alignment is correct. Make any corrections.
Cut through the Wall
The easiest way to make the penetration is to drill pilot holes at each of the 4 corners first. Then use a drywall saw to cut out the rectangle. Cut out and remove the insulation. Next, drill pilot holes through the siding.
Cut out the section of siding. Which type of saw is used depends on the siding material and the tools on hand. Two effective choices are a jigsaw or a Sawzall. Then it’s a simple matter to slide in the exterior wall vent to mate up with the damper on the range hood.
It may be necessary to extend the vent with the correct size sleeve or cut it down using aviation or tin snips.
Finally, be sure everything is aligned properly, mount the range hood, and secure the exterior vent to the siding.
Round Duct Installation
When using a round duct to vent through the roof, there are generally 2 options: straight up, or an elbow. The option used depends on individual circumstances. After routing the duct up into the attic, determine where it will exit the roof.
Mark the hole on the underside of the roof sheathing and drill pilot holes through the roof from the attic side. Then, cut the hole from the outside of the roof. Install the vent, making sure the upper shingles cover half of the vent flange.
Finally, connect the duct in the attic to the vent. Chances are that that an adjustable elbow will be necessary to make the final connection. Apply metallic duct tape on all duct joints and secure the duct to a rafter or roof truss with a metal strap.
Tips on Buying a New Kitchen Range
Consumer Reports has an online site, but they charge a subscription fee for the service. Instead, go to the nearest public library and compare the ratings for the different brand appliances. Manufacturers’ Internet sites How Stuff Works are also good sources of information about kitchen stoves and ranges.
Next, make a list of all the appliance dealers in the area. Many furniture stores, like Sears also sell brand name appliances. But when looking at after sale service, furniture stores usually contract out their appliance repair or refer to the manufacturer. Retailers who specialize in selling only large appliances generally service what they sell. Sometimes a better deal can be made by purchasing a stove and refrigerator together.
Appliance manufacturers offer a “Limited Warranty” usually good for one year from the date of purchase. This warranty only covers factory defects in materials and workmanship. Most appliance retailers offer Extended Warranties, which are good for three to five years, after the manufacturer’s warranty has expired. The decision to purchase an extended warranty may depend on the consumer’s confidence in the product.
Types of Range Ovens
When choosing a new electric range, don’t be confused by the terms Self-Cleaning and Easy Clean oven. A self-cleaning oven has an element either around the door opening or on the door itself that reaches a high temperature, usually one thousand degrees Fahrenheit. The high heat burns off all the residues inside the oven leaving a small pile of ash that can be wiped up with damp cloth. The oven racks, however, must still be removed and cleaned separately. An Easy Clean oven has a special coating, which makes it easier to clean, but still requires some scrubbing.
Convection ranges are a bit pricier because they have a fan, which is usually located at the back of the oven. The fan forces the heated air inside the oven to circulate around the food being cooked. The forced, hot air cooks foods much faster than a conventional oven. This oven also cooks foods at about 20 percent lower temperatures than the recipes’ suggested, cooking time. The down side for cooks is the need to recalculate recipes times and temperatures.
Kitchen designers suggest the range hood or vent hood match the color and finish of the range. Also check to ensure the range hood or vent has a fan motor large enough to quickly exhaust all cooking odors.
Smooth top or coil burners
Smooth top ranges have a ceramic top with heating units underneath. The advantage of this system is the ease of cleaning. Simply give the top a quick wipe with a damp cloth after each use. If foods do splash over and burn onto the ceramic, there is a ceramic, stove cleaner that can be bought at many hardware or home improvement stores.
The down side to ceramic is it scratches easily. Therefore, aluminum, glassware or cast iron cookware is not recommended. Coil burners have been around for a long time, however, over time the coils may burn out and have to be replaced. And cleaning involves removing and washing the drip pans underneath the coils.
Cook stoves and ranges come in a wide variety of colors, finishes and styles sure to compliment any kitchen design. Some people prefer a gas range to an electric range, but whatever the choice, today’s appliances are definitely more energy efficient than they were even five years ago.
