STEP 3: DRAIN CONNECTION
The drain outlet is located on the back of the steamer, as shown in Figure 6. The drain connector on the steamer is 1"
(32 mm) NPT female.
Position the steamer near, but not on top of, an open floor drain. DO NOT directly plumb the steamer unless you also
install an “open funnel” downstream of this connection in the drain system. Make the drain line from the steamer to the
air gap above the “open funnel” as short as possible. There should be no horizontal piping between the steamer and
the air gap above the open funnel. The open funnel is intended to eliminate any water from entering the steamer
because of a blocked drain, and it also prevents any back pressure within the steamer cavity. Any connection that
allows the build-up of back pressure in the steamer (such as a reduction in pipe size to a line smaller than 1", or more
than one 90-degree angle in the line prior to the open funnel drain discharge point) may cause personal or property
damage and will therefore void the warranty. The steamer is a pressureless, free-venting steam cooker and will not
operate properly unless the drain line is short, at a steep angle, and open! See Figure 7 on the next page.
