VSX BOILER BASE SERIES CONVECTION STEAMERS - STEAMER OPERATION
The steamer and its parts are hot. Use care when operating, cleaning or servicing the steamer.
The cooking compartment contains live steam. Stay clear when opening each door.

Cabinet Base Boilers

Ensure that all utility connections to the steamer have
been made and are turned on.
On models that are Cal-Code/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
1. Open the cabinet door and turn main power
switch ON.
• The red light will illuminate.
• Water will begin filling the boiler.
• The blowdown solenoid valve will close.
2. The boiler should fill in four to eleven minutes.
NOTE: Both valves on gauge glass assembly must
be open to fill the gauge.
NOTE: On older models equipped with a manual
"ball" type blowdown valve, the valve must be closed
for the boiler to fill.
3. Observe water level gauge glass:
• Verify that water is in boiler.
• Gauge glass is about half full.
4. 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.
NOTE: The knob on the gas combination control
valve has three positions (On-Pilot-Off) for control of
main burners and pilot.
5. Manual Ignition Models
A. Turn knob on gas combination valve to
PILOT then depress and light pilot burner
with a lit taper.
B. 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.

C. 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.
D. After approximately 15 minutes, steam
should be present for cooking product.
Observe that the boiler pressure gauge
indicates steam pressure of 8-10 psi.
CAUTION
Do not attempt to manually light the pilot
in an automatic-type ignition system.
NOTE: The knob on the gas combination control
valve has two positions (On-Off) for control of main
burners and pilot.
6. Automatic Ignition Models
• 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.
• 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.
A. 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.
NOTE: 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.
B. If the pilot lights, a signal is sent back
through the ignition cable indicating the
presence of pilot flame and sparking stops.
C. 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.
