Introduction

DESCRIPTION

The ST-5G is a gas red countertop pressureless cooker.
The cooking compartment is equipped with a three-piece

door with inner gasket plate isolated from the exterior sur­face. Door latch operates by action for positive sealing on
inner door. Operation controls are displayed on a front­mounted panel and included timer with indicator lights for
selection of constant steam or selectable timed cooking.
The unit is equipped with a gas red, stainless steel gen­erator operating at 0 PSI and rated at 45,000 BTU.

BASIC FUNCTIONING

The cooker becomes operational when it is set to con­stant steam, or the timer is set at the desired cooking time
and the compartment door is closed.

At the end of the set interval, timer contact switch to shut
off the cooking operation and sound a signal buzzer. The
buzzer is silences by returning the timer dial to the OFF
position. In the constant steam mode, cooking operation
will be continuous.

Steam emitted from the compartment along with liquid

cooking drainage is directed through a drain screen inside
the compartment into the cooker drain line to the genera­tor drain box. A cold water condenser in the rear of the
cooking chamber helps to condense the steam prior to
discharge into the drain.

The steamer freely vents itself by the negative pressure
created by the condensate water drainage. This negative
pressure prevents steam leakage around the door gasket
and helps draw steam though the cooking compartment.
Steam leakage at the door may indicate a plugged or im­properly installed drain screen.
