NOTE: Hot water maximizes steam production but is not
required. Cold water may be supplied to both in-
lets if hot water is not available.
Connect the appliance to quality cold water via a pressure
hose with 3/4” (1/9 cm) couplings. Cold water is connect-
ed to the left solenoid/pressure regulator as viewed from
the rear of the oven. Hot water connection, right solenoid/
pressure regulator, to the boiler is recommended. A shut
off valve must be provided adjacent to the oven.
NOTE: Hot water must not be applied to the cold water
inlet.

A 2” (5 cm) copper pipe with standard drain pitch must
be run to an open drain or connected to a standpipe
equipped with a vent.
NOTE: The waste water can also be directed to a nearby
floor drain. Flexible hose which allows trapped
water to accumulate in sagged runs must be
avoided.
1. Find the drain connection on the lower rear of the unit.
2. Loosen the coupling clamps. Attach a 2” (5 cm) cop-
per drain pipe to the drain connection. Retighten the
coupling clamps.
NOTE: The open end of the drain should be installed
facing the floor. Copper line, used for installation
to an open drain or floor sink, must be supplied
by the installer. Use of a trap inline will cause
drain backup.
