in the tube on the right side of the overflow deck. The
upper sensor controls the water level and the lower
sensor controls the low water safety shut-off system.
Once the water On/Off switch is turned on, the blue light
will come on and start to fill until the water level reaches
the upper sensor. The burners will not come on until the
water level reaches the lower sensor, preventing the
P
asta System from being damaged if there is little or no
water in it. Both sensors must be cleaned with the
sensor brush (like the one provided) on an hourly basis
or whenever starch foams up to maintain the proper
water level. Sensors must be cleaned more often in
areas with hard water, in installations with softened
water (due to the salt in the water) or when oil or salt is
placed in the water for cooking.
The brush must be checked on a regular basis and
replaced whenever it starts to wear. Replacement
brushes can be ordered under part number 009297.
Do not store the sensor brush in the sensor tube as
it could contact the sensors, which could allow the
water level to drop below the heat tubes and
damage the Pasta System.
Using a worn brush could damage the sensors.
NOTE: Water level problems caused by the sensors
not being cleaned adequately will not be covered under
warranty.
WHEN THE WATER LEVEL FALLS BELOW THE
LOWER SENSOR THE BURNERS WILL SHUT OFF.
IF THEY STAY ON, TURN THE MAIN POWER
ON/OFF SWITCH TO THE “OFF” POSITION AND
CLEAN THE SENSORS THOROUGHLY. IF THE
PROBLEM STILL OCCURS, HAVE THE WATER
AUT
O-FILL SYSTEM CHECKED BY A QUALIFIED
SER
VICE TECHNICIAN.

V SERVICE DIAGNOSIS
The burners when on will produce clear blue flames
directed at the inside walls of the heat transfer tubes.
The radiant’s fins, located towards the rear of each
transfer tube, will glow bright red, helping to ensure
optimum heat distribution into the Pasta System
vessel. All radiants should be pushed to the rear and
then pulled gently forward (until their retaining clips
engage the rear of the tubes) for optimum heat
distribution.
On constant pilot models, the pilot light will be
between
3
/8" to
1
/2" high and will use about 180 BTU’s
of gas per hour.
The runner pilot tube is used to ignite the burners.
Flames from the tube should be clear blue and
between
3
/8" to
1
/2" high spread across the entire tube.
The burners will ignite almost instantly after the
thermostat calls for heat.
A. Water Fill and Safety Shut-Off Circuit Board and
Sensor Check
When properly maintained, the Automatic Water Fill and
Low Water Safety Shut-off Systems maintain the water
at the proper level and prevent the burners from coming
on if the water level is too low.
NOTE: Hard water, excessive starch and salt in water
may cause water to not fill. Oil in water may cause water
to not stop filling.
B. Trouble shooting
The following trouble shooting charts are only to be
used as a guide to qualified service personnel. See
pages 12-15. Keating recommends that you use a
qualified service company.
