f. To remove burned-on foods, use a brush,
sponge, cloth, plastic or rubber scraper, or
plastic wool along with the cleaning solution.
To reduce effort required in washing, let the
detergent solution sit in the kettle for a few
minutes and soak into the residue. Do NOT
use abrasive materials or metal tools that
might scratch the surface. Scratches make
the surface harder to clean and provide
places for bacteria to grow. Do not use steel
wool, which will leave particles in the surface
and cause eventual corrosion and pitting.
g. The outside of the unit may be cleaned with a
warm water (100°F or less) spray.
Do not
use a high pressure spray.
h. The outside of the unit may be polished with
a recognized stainless steel cleaner like
“Zepper” from Zep Manufacturing Company.
i. When the equipment needs to be sanitized,
use a sanitizing solution equivalent to one
that supplies 200 parts per million chlorine.
Obtain advice on the best sanitizing agent
from your supplier of sanitizing products.
Following the supplier’s instructions, apply the
sanitizing agent after the unit has been
cleaned and drained. Rinse off the sanitizer
thoroughly.
j. It is recommended that the unit be sanitized
just before use.
k. Clean the kettle thoroughly. If there is
difficulty removing mineral deposits or a film
left by hard water or food residues, then
use a de-liming agent, such as Groen
De-limer De-Scaler (Part Number 114800),
Lime- Away from ECOLAB or an equivalent,
following manufacturer directions.
l. Rinse and drain the unit thoroughly before
further use.
m. If especially difficult cleaning problems
persist, contact your cleaning product
supplier for assistance. The supplier has a
trained technical staff with laboratory facilities
to serve you.
Sequence of Operation
The following “action-reaction” outline is provided to
help understand how the equipment works.
1. When the power switch is turned on, it starts
the spark igniter and opens the automatic valve
for the pilot burner. The spark ignites a pilot
flame, which heats the sensor. The sensor then
sends a signal to turn off the spark. The flame
thereafter acts as a standing pilot until the
power is turned off.
2. If the pilot flame is not sensed within 90
seconds after spark begins, a timer shuts down
the entire operation. To attempt a second trial
for ignition, turn off the power switch. Check
the gas supply valves and wait five minutes
before trying again by switching power on. If
you cannot establish a pilot flame in four tries,
close all valves, turn off the power, and contact
an authorized Groen Service Agency.
3. When the operator sets a temperature on the
thermostat, it causes the automatic valve to
admit gas to the main burner, where it is ignited
by the pilot flame. When the kettle reaches the
set temperature, the thermostat switch opens.
This stops the signal to the gas control valve
and shuts off gas to the main burner. The pilot
flame remains lit. When the kettle cools below
the set temperature, the thermostat switch
closes and starts another cycle. On and off
cycling continues and maintains the kettle at the
desired temperature. This action is indicated by
the Heat indicator light.
The kettle has the following safety features in
addition to the 90-second ignition timer:
1. Low water cutoff relay that will shut off gas
supplies to all burners until the jacket water
level is corrected.
2. High limit pressure switch, set to open at about
43 PSI and to shut down the burners until jacket
pressure is decreased.
3. Pop pressure relief valve, which will release
steam if jacket pressure exceeds 50 PSI.
4. Tilt switch, which shuts off all burners when the
kettle is tilted.
5. Gas pressure regulator built into the gas control
valve.
