MODELS: STHE-7-TGG, STHE-12-TGG, STHE-16-TGG
2.0 INTRODUCTION
DESCRIPTION
The STHE series steamers are pressureless steam cookers consisting of two independently
controlled compartments enclosed in a single cabinet. Each compartment is equipped with a
separate heavy duty door with inner gasket plate isolated from the exterior surface. Door
latches operate by action for positive sealing of inner door. Operation controls are displayed on
a single front-mounted panel and include separate timers with indicator lights for selection of
constant steam or 60-minute-long duration cooking. Two gas fired, stainless steel generators
operating at "0" psi (0 kPa) and rated at 70,000 BTU (STHE-7-TGG) or 95,000 BTU (STHE-12-
TGG and STHE-16-TGG) are located in the bottom cabinet and may be operated separately.
BASIC FUNCTIONING
The steamers may be operated with only one compartment in use; or both may be used
simultaneously. Each compartment is equipped with identical controls, allowing selection of
constant steam or 60-minute timer operation. 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.
When steam flowing inside the compartment has raised the interior temperature to 195 degrees
F, the contacts of a thermostatic switch close, completing the circuit to the timer motor and
starting the coking time period. At the end of the set interval, timer contacts switch to shut off
the cooking operation and sound a signal buzzer. The buzzer is silenced by returning the timer
dial to the OFF position. In the constant steam mode, 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 that is
automatically actuated by a thermostatic cooling valve to condense the steam to water prior to
discharge into the floor drain.
