A downdraft stove looks and operates much like a typical selection, with the exception that a downdraft stove has a built-in ventilation system, which permits steam, gasses and grease in the cooking process to be captured and vented to the outside from beneath or behind the stove. This system eliminates the need for an overhead range hood, which enables the stove to be more easily set up in a kitchen in which an overhead-mounted range hood would be difficult to install.
Venting Through the Wall
Switch off the breaker into the outlet that forces the stove in the circuit breaker panel.
Measure the size and location of the port opening on the back of the stove, and using a pencil, mark the opening to the wall where the stove will be located. Locate the studs in this wall using a hammer, and mark the stud locations on the wall. If the vent opening does not reside cleanly in between the two nearest studs, check the installation guide to the range about ways to correct the position of the port so you do not have to cut any wall studs. Then reposition the port along with the marks on the wall accordingly.
Cut around the perimeter of the port markers using a utility knife, and remove the piece of drywall. Gently push back the insulation to attain the outside wall sheathing, checking for any electrical cables which might be in the way. If any wiring is impeding the port setup, stop and call an electrician for help in relocating the wiring.
Drill pilot holes at the exterior sheathing and siding corresponding to each corner of the port opening with a very long 1/2-inch drill bit and a power drill. Then, go out and cut the perimeter of the port opening between the four corner holes using a reciprocating saw.
Apply a bead of exterior caulk into the flange around the wall cap included using the stove, then slide the duct throughout the opening and attach the wall cap into the ground with the stainless steel mounting screws. Wipe away any caulking that seeps out of the flange around the ground.
Rank the downdraft stove in front of the opening. Combine the flexible vent link between the duct at the wall along with the port opening on the back stove, then thrust the stove into position. Connect the power cord into the wall outlet. Turn the breaker and test the performance of the stove.
Venting Between Floor Joists
Switch off the breaker into the outlet that forces the stove in the circuit breaker panel.
Tilt the stove back and measure the size and location of the port opening on the bottom of of the stove, and using a pencil, mark the opening onto the ground under the installation place. Locate the floor joists using a stud finder, and mark the joist locations around the ground. If the vent opening does not reside cleanly in between the two nearest joists, check the setup guide to your range about ways to correct the position of the port so you do not have to cut any joists. Then reposition the port along with the marks onto the ground accordingly.
Drill a 1/2-inch hole at each of the four corners of the cutout, taking care that you do not push the bit too deeply into the crawl space below. Then enter the crawl space and locate the four holes of the mounting place. Pull back the insulation, checking for any electrical cables which might be in the way. If any wiring is impeding the port setup, stop and call an electrician for help in transferring the wiring.
After checking for electrical wiring at the install location, go back to the kitchen and cut the perimeter of the port opening between the four corner holes using a reciprocating saw. Then position the stove into position over the hole.
Crawl underneath the kitchen and slip the rectangular duct to the cutout and to the foundation of the port casing beneath the stove. Attach a 6-inch metallic elbow into the duct, and attach the elbow using 6-inch metallic duct clamp.
Add a part of 6-inch duct into the end of the elbow, then connecting the two with a metallic duct clamp. Wrap a part of steel vent strap around the duct and attach it to the nearest joist using a 1 1/2-inch wood screw. Keep adding sections of hanging and duct straps until you arrive at the perimeter wall of the house in which you would like to mount the port.
Drill pilot holes at the exterior sheathing and siding corresponding to each corner of the port opening with a very long 1/2-inch drill bit and a power drill. Then, go out and cut the perimeter of the port opening between the four corner holes using a reciprocating saw.
Apply a bead of exterior caulk into the flange around the wall cap included using the stove, then slide the duct throughout the opening and connect the ducting under the house before attaching the wall cap into the ground with the stainless steel mounting screws. Wipe away any caulking that seeps from the flange around the siding.
Connect the power cord into the wall outlet. Turn the breaker and test the performance of the stove.
