VL SERIES STEAMERS - GENERAL
Pa
e 12 of 88
Handhole Cover Assembly ....... When unbolted and removed, allows internal examination and cleanin
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 pipin
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 pipin
assembly option, allows the boiler and
other internal components to be delimed, easily removin
calcium, lime
and rust build up.
Gas Pilot ..................... Should always remain lit to li
ht the main burners upon a call for heat
unless the steamer will not be in use for an extended period. If the pilot
flame
oes out, wait 5 minutes before reli
htin
.
Gas Burners................... Heats the water in the boiler to
enerate steam.
Gas Combination Control Valve . . . A
as solenoid valve that opens to allow
as flow when a call for heat is
made. Also re
ulates the manifold
as pressure and supplies the
as
pilot.
Transformer ................... Provides 24VAC power to i
nition control module. (
as models with
electronic i
nition)
Ignition Control Module ......... Controls and monitors
as heatin
. Ener
izes pilot valve coil to supply
as to pilot,
enerates spark to i
nite
as at the pilot, monitors the
presence of flame and ener
izes main valve coil upon a call for heat to
supply
as to the main burners. The pilot and main solenoids are part of
the
as combination control valve. (
as models with electronic i
nition)
Ignition Control Module
Reset (ON/OFF) Switch .......... Controls power to the i
nition control module and allows a reset of the
module if the
as i
nition exceeds trial time. (
as models with electronic
i
nition)
Heater Contactor
(Electric Boilers) ............... When coil is ener
ized, supplies power to the electric heatin
elements.
Heating Elements
(Electric Boilers) ............... Heats the water in the boiler to
enerate steam.
Steam Header Assembly ......... Main steam supply line from the boiler to the steam header inlet in the
cookin
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 buildin
steam (direct and
re
enerated models) to supply the compartments a steam pressure of 6
psi. Standard on PS, option on MS, SS and AS compartment controls.
