| VL SERIES STEAMERS - GENERAL |
Handhole Cover Assembly | . When unbolted and removed, allows internal examination and cleaning |
| of boiler shell and its components if required. |
Boiler Pressure Gauge | . Indicates the amount of steam pressure in the boiler. |
Check Valve | . On models with the delime piping assembly option, prevents the ejection |
| of hot water and steam out of the delime funnel if the manual delime fill |
| valve were to be opened. |
Delime Port Assembly | . On models with the delime piping assembly option, allows the boiler and |
| other internal components to be delimed, easily removing calcium, lime |
| and rust build up. |
Gas Pilot | . Should always remain lit to light the main burners upon a call for heat |
| unless the steamer will not be in use for an extended period. If the pilot |
| flame goes out, wait 5 minutes before relighting. |
Gas Burners | . Heats the water in the boiler to generate steam. |
Gas Combination Control Valve . . | . A gas solenoid valve that opens to allow gas flow when a call for heat is |
| made. Also regulates the manifold gas pressure and supplies the gas |
| pilot. |
Transformer | . Provides 24VAC power to ignition control module. (gas models with |
| electronic ignition) |
Ignition Control Module . . . . . . . . .

Steam Header Assembly . . . . . . . . .
Controls and monitors gas heating. Energizes pilot valve coil to supply gas to pilot, generates spark to ignite gas at the pilot, monitors the presence of flame and energizes main valve coil upon a call for heat to supply gas to the main burners. The pilot and main solenoids are part of the gas combination control valve. (gas models with electronic ignition)
Controls power to the ignition control module and allows a reset of the module if the gas ignition exceeds trial time. (gas models with electronic ignition)
When coil is energized, supplies power to the electric heating elements.
Heats the water in the boiler to generate steam.
Main steam supply line from the boiler to the steam header inlet in the cooking control compartment.
Pressure Relief Valve . . . . . . . . . . . A mechanical device that opens to relieve steam pressure in the boiler if the pressure exceeds 15 psi.
Compartment Pressure
Regulating Valve . . . . . . . . . . . . . . . Reduces steam pressure form the boiler or building steam (direct and regenerated models) to supply the compartments a steam pressure of 6 psi. Standard on PS, option on MS, SS and AS compartment controls.
