INSTALLATION
Step 7: Water Drains
Each oven has two drain tubes: a 2" O.D. tube that drains the oven cavity and a 3/4" O.D. tube that drains
the drain trough on the front of the oven below the door (see illustration on page 12). Position the oven near,
but not on top of, an open floor drain. DO NOT directly plumb to the oven unless you also install an “open
funnel” downstream of this connection in the drain system. Make the drain lines from the oven to the air gap
above the “open funnel” as short as possible. There should be no horizontal piping between the oven and the
air gap over the “open funnel.” The “open funnel” is intended to eliminate any water from entering the oven
because of a blocked drain, and it also prevents any back pressure within the oven cavity. The oven must
be free-venting to the atmosphere. Any connection that allows the build-up of back pressure in the oven
(such as a reduction in pipe size to a line smaller than 2" or a 90 degree angle in the line prior to the “open
funnel” drain discharge point) may cause personal or property damage and therefore will void the warranty.
The EZ Com is a pressureless, free-venting oven and will not operate properly unless the drain lines are
short, at a steep angle, and open!
