VSX SERIES STEAMERS - COMPONENT FUNCTION AND LOCATION
Pressure Gauge - indicates boiler steam pressure.
Normal operating pressures are listed below.

Regenerated
Drain - drains steam condensate and water from
cooking compartments and 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 easily be delimed to remove
calcium, lime and rust build up. See "BOILER"
under "SERVICE PROCEDURES".
Standing Pilot (Gas Boilers) - 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.
Main Burners (Gas Boilers) - heats the water in
the boiler to generate steam.
Combination Control Valve (Gas Boilers) - a gas
solenoid that opens to allow gas flow when a call for
heat is made and also regulates the manifold gas
pressure.
Pressure Regulating Valve (Direct &
Regenerated Steam) - regulates the manifold
steam pressure between 10-12 psi.
Magnetic Contactor (Electric Boilers) - when coil
is energized, supplies power to the electric heating
elements.
Heating Elements (Electric Boilers) - heats the
water in the boiler to generate steam.
