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
li
g
hts 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 li
g
ht will illuminate, water
will be
g
in fillin
g
the boiler and the blowdown
solenoid valve will close. The boiler should fill,
in four to eleven minutes. Observe water level
g
au
g
e
g
lass to verify that water is in boiler and
that the level in the
g
au
g
e
g
lass is about half
full. Both valves on
g
au
g
e
g
lass assembly must
be open to fill the
g
au
g
e. Older models
equipped with a manual “ball” type blowdown
valve must be closed for the boiler to fill. The
cyclin
g
pressure switch will maintain the proper
steam pressure in the boiler by cyclin
g
the
heatin
g
system on and off to
g
enerate steam
pressure.

On Models with Manual Ignition
- The
knob on the
g
as combination control valve
has three positions (On-Pilot-Off) for
control of main burners and pilot. Turn
knob on
g
as combination valve to PILOT
then depress and li
g
ht 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
g
o out, wait 5 minutes
before reli
g
htin
g
.
Turn knob on
g
as combination control
valve to ON. If the water level in the boiler
has reached the minimum level, burners
will i
g
nite and be
g
in to heat the water in
the boiler. After approximately 15 minutes,
steam should be present for cookin
g
product. Observe that the boiler pressure
g
au
g
e indicates steam pressure of 9-11
psi for models with a pressure re
g
ulatin
g
valve or 4-6 psi for models without the
valve.
B.
On Models with Automatic Ignition
-
The knob on the
g
as combination control
valve has two positions (On-Off) for
control of main burners and pilot. For the
automatic i
g
nition system to work, the
knob must be set in the ON position or
g
as
for the pilot and main burners will not flow.
Also, the i
g
nition 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 i
g
nition control module.
A red li
g
ht 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 i
g
nition control modules RESET
switch is in the ON position, sparkin
g
will
be
g
in three seconds later to li
g
ht the
standin
g
pilot. If the pilot li
g
hts, a si
g
nal is
sent back throu
g
h the i
g
nition cable
indicatin
g
the presence of pilot flame and
sparkin
g
stops. If the water level in the
boiler has reached the minimum level, the
burners will i
g
nite and be
g
in to heat the
water in the boiler. After approximately 15
minutes, steam should be present for
cookin
g
product. Observe that the boiler
pressure
g
au
g
e indicates a steam
pressure of 9-11 psi for models with a
pressure re
g
ulatin
g
valve or 4-6 psi for
models without the valve. If a pilot flame
is not established immediately, sparkin
g
will continue for 90 seconds. After that
duration, the i
g
nition control module will
lock out and needs to be reset to start the
pilot and burner li
g

Electrically Powered Steam Boiler
Open the cabinet door and turn main power switch
ON. The red li
g
ht will illuminate, water will be
g
in
fillin
g
the boiler and the blowdown solenoid valve
will close. The boiler should fill, in approximately 11
minutes. Observe water level
g
au
g
e
g
lass to verify
that water is in boiler and that the level in the
g
au
g
e
g
lass is about half full. Both valves on
g
au
g
e
g
lass
assembly must be open to fill the
g
au
g
e. 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 ener
g
ize and be
g
in to heat the water in
the boiler. After approximately 15 minutes, steam
should be present for cookin
g
product. Observe that
the boiler pressure
g
au
g
e indicates steam pressure
of 9-11 psi for models with a pressure re
g
ulatin
g
valve or 4-6 psi for models without the valve.
