STEAMER OPERATION

Ensure that all utility connections to the steamer
have been made and are turned on.
On models that are CSD-1 equipped, amber colored
lights for hi pressure and low water level will
illuminate and stay on until the boiler is full and the
manual reset switch pressed.

Gas Powered Steam Boiler

5.
Open the cabinet door and turn main power
switch ON. The red light will illuminate, water
will begin filling the boiler and the blowdown
solenoid valve will close. The boiler should fill,
in four to eleven minutes. Observe water level
gauge glass to verify that water is in boiler and
that the level in the gauge glass is about half
full. Both valves on gauge glass assembly must
be open to fill the gauge. Older models
equipped with a manual "ball" type blowdown
valve must be closed for the boiler to fill. The
cycling pressure switch will maintain the proper
steam pressure in the boiler by cycling the
heating system on and off to generate steam
pressure.
A.
On Models with Manual Ignition - The
knob on the gas combination control valve
has three positions (On-Pilot-Off) for
control of main burners and pilot. Turn
knob on gas combination valve to PILOT
then depress and light pilot burner with a
lit taper. Maintain knob in depressed
position for about 30 seconds and release.
Observe that pilot burner flame stays on. If
the flame should go out, wait 5 minutes
before relighting.
Turn knob on gas combination control
valve to ON. If the water level in the boiler
has reached the minimum level, burners
will ignite and begin to heat the water in
the boiler. After approximately 15 minutes,
steam should be present for cooking
product. Observe that the boiler pressure
gauge indicates steam pressure of 9-11
psi for models with a pressure regulating
valve or 4-6 psi for models without the
valve.
B.
On Models with Automatic Ignition -
The knob on the gas combination control
valve has two positions (On-Off) for
control of main burners and pilot. For the
automatic ignition system to work, the
knob must be set in the ON position or gas
for the pilot and main burners will not flow.
VL SERIES STEAMERS - GENERAL

Electrically Powered Steam Boiler

Open the cabinet door and turn main power switch
ON. The red light will illuminate, water will begin
filling the boiler and the blowdown solenoid valve
will close. The boiler should fill, in approximately 11
minutes. Observe water level gauge glass to verify
that water is in boiler and that the level in the gauge
glass is about half full. Both valves on gauge glass
assembly must be open to fill the gauge. Older
models equipped with a manual "ball" type
blowdown valve must be closed for the boiler to fill.
If the water level in the boiler has reached the
minimum level, the heater contactors will close, the
heaters will energize and begin to heat the water in
the boiler. After approximately 15 minutes, steam
should be present for cooking product. Observe that
the boiler pressure gauge indicates steam pressure
of 9-11 psi for models with a pressure regulating
valve or 4-6 psi for models without the valve.

Regenerated Steam Powered Boiler

Open the cabinet door and turn main power switch
ON. The pilot light will illuminate, water will begin
filling the boiler and the blowdown solenoid valve
will close. Models equipped with a manual "ball
type" blowdown valve need to be closed for the
boiler to fill. The boiler should fill, in approximately
15 minutes.

Also, the ignition control module
ON/OFF/RESET switch must be in the ON
position to operate. This switch is located
on the upper left side of the electrical
control box for the ignition control module.
A red light will illuminate when the switch
is in the ON position. DO NOT ATTEMPT
TO MANUALLY LIGHT THE PILOT IN AN
AUTOMATIC TYPE IGNITION SYSTEM.
After the main power switch is turned ON
and the ignition control modules RESET
switch is in the ON position, sparking will
begin three seconds later to light the
standing pilot. If the pilot lights, a signal is
sent back through the ignition cable
indicating the presence of pilot flame and
sparking stops. If the water level in the
boiler has reached the minimum level, the
burners will ignite and begin to heat the
water in the boiler. After approximately 15
minutes, steam should be present for
cooking product. Observe that the boiler
pressure gauge indicates a steam
pressure of 9-11 psi for models with a
pressure regulating valve or 4-6 psi for
models without the valve. If a pilot flame
is not established immediately, sparking
will continue for 90 seconds. After that
duration, the ignition control module will
lock out and needs to be reset to start the
pilot and burner lighting cycle again.
