Step 3: Drain Connection
The drain outlet is located on the back of the steamer, as shown in Figure 4 on page 9. The drain connector
on the unit is 3/8" NPT male.
Position the unit near, but not on top of, an open floor drain. DO NOT directly plumb to the unit unless you
also install an “open funnel” downstream of this connection in the drain system. Make the drain line from the
unit to the air gap above the “open funnel” as short as possible. There should be no horizontal piping
between the unit 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 unit (such as a reduction
in pipe size to a line smaller than 3/8", 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 unit
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 6 below.
