Jenn Air downdraft stove tops get their name from the built-in ventilation system that pulls odors and smoke downward and into a hidden filter so they do not dissipate throughout your home. Jenn Air stove tops are available in gas and electric-powered models, all of which are installed atop the cabinet framework. Stove tops are independent of an oven element, and as such are favored in tight spaces and for those who do not have a need to bake or broil.
Things You'll Need
- Reciprocating saw
- Tape measure
- Large screw-tight vent clamp
- Wire nuts
- Electrical tape
- Pipe joint compound
- Flexible gas line
- Hole cutter
- 6-inch aluminum venting
- 6-inch wall cap
- Work gloves
- Eye goggles
Turn off the power to your stove junction box. Use a reciprocating saw to cut the top of your cabinet base into a suitable opening for your Jenn Air stove top. If you are installing a 30-inch model, you will need a top opening that measures 28 1/4-by-21 1/8 inches. If your are installing a 36-inch model, you will need a top opening that measures 34 1/8- by-21 1/8 inches.
Rest the stove top face down onto a padded flat surface. Install the self-stick foam padding included with your stove top around the entire underside rim. Peel off the wrapper and press the strip into place firmly. Place the stove top onto the opening with the blower side down.
Slide a large screw-tight vent clamp over the end of your vent pipe, and fit the pipe over the vent outlet at the rear of the blower. Use your screwdriver to tighten the clamp. If you are installing an electric stove top, move on to step 4 -- if gas, move to step 5.
Use your screwdriver to remove the cover from your stove junction box. Stretch out the power wires inside the box and connect them to your stove top power wires. Match each wire color for color, placing black with black, white with white, red with red and green or ground with ground. Twist each set of wires together tightly, then use wire nuts to tighten the connection. Wrap each wire nut and about 1 inch of coated wire with two twists of electrical tape to protect the connection. Close the junction box cover with your screwdriver.
Apply a coating of pipe joint compound to the threads on the gas fitting, which extends from the underside of your stove top. Install the gas flow regulator --included with the stove top -- by threading it onto the gas fitting by hand, then use your wrench to tighten it fully. Apply a coating of pipe joint compound to the threads at one end of a flexible gas line. Screw the line into the regulator and tighten with your wrench. Apply compound to the other end of the line, and screw it into the wall-mounted, gas shutoff valve behind your installation location and tighten with your wrench. Turn the valve to the "On" position and test the stove.
Tips & Warnings
- Your Jenn Air Downdraft stove top requires at least 30 inches of space between the top edge of the cook top and the bottom of the cabinet on which it is installed. It also requires at least 30 inches of space between the top edge of the cook top and the bottom edge of the cabinet above.
- Your stove top requires a vent pipe through which vapors it absorbs are released. If you do not have an existing vent system, vent piping can be run directly through the back wall of the cabinet and the exterior wall of the home. Use a hole cutter to make the hole, and use 6 inch aluminum venting to create the system. Close the outside of the vent with a 6-inch wall cap. The blower beneath the stove top can be rotated to face whichever direction is necessary to suit your venting system.
- Check your local building codes to ensure what type of venting system and gas line connection are required in your area.
- Use caution when installing gas-powered stove tops. Natural gas is flammable, explosive and hazardous if inhaled. Contact your local gas company and 911 immediately if you smell gas in your home.
- Never attempt to perform maintenance or repairs on an electrical appliance that is plugged in. Electric current can cause serious injury or death.
- Use caution when working with dangerous tools, such as saws. Serious injury can occur. Wear work gloves and eye goggles for protection.
