NOTICES

There are three different types of notices that you should be familiar with, a NOTICE, CAUTION,
and WARNING. A NOTICE is a special note used to call attention to a particularly important
point. CAUTION is used to point out a procedure or operation which may cause equipment
damage. The WARNING notice is the most important of the three because it warns of an operation
that may cause personal injury. Please familiarize yourself with your new Rethermalizer before
operating it and heed the notices throughout this manual. The WARNINGS are listed below and on
the following page for your review prior to operating the unit.

FOR YOUR SAFETY

DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity of this
or any other appliance.

WARNING: Improper installation, adjustment, alteration, service or maintenance can
cause property damage, injury or death. Read the installation, operating and
maintenance instructions thoroughly before installing or servicing this equipment.

TO THE PURCHASER

POST IN A PROMINENT LOCATION INSTRUCTIONS TO BE FOLLOWED IN
THE EVENT THAT AN OPERATOR SMELLS GAS. OBTAIN THIS INFORMATION
FROM YOUR LOCAL GAS SUPPLIER.

SAFETY SAFETY SAFETY SAFETY SAFETY

WARNING

This appliance is equipped with a three prong (grounding)
plug. This is for your protection against shock hazard in
the event of equipment malfunction. Always plug the unit
directly into a properly grounded three-prong receptacle.
DO NOT cut or remove the grounding (third) prong.

WARNING

DO NOT use an open flame to check for gas leaks! Keep
all open flames away from the Rethermalizer until the
installation is complete.

WARNING

A Rethermalizer equipped with casters and a flexible
power cord, must be connected to the gas supply with a
Quick-Disconnect device. This quick disconnect must
comply with ANSI Z24.41. To limit the movement of the
unit without depending on the connector or quick
disconnect, a restraining cable must also be installed.

WARNING
There is an open gas flame inside the Rethermal izer. The
unit may get hot enough to set nearby materials on fire.
Keep the area around the unit free from combustibles.

WARNING
Ensure that the Rethermalizer can get enough air to keep
the flame burning correctly. If the flame is starved for air
it can give off a dangerous carbon monoxide gas. Carbon
Monoxide is a clear odor -less gas that can cause
suffocation.

WARNING
Carbon monoxide can build up if you block the flue.
Blocking the flue will also cause the unit to overheat. DO
NOT obstruct the flow of combustion/ventilation or air
opening around the Rether malizer. Ensure that you meet
the minimum clearances specified in the installation
instructions. Adequate clearance around the unit is
necessary for servicing and proper burner operation.

WARNING

The power supply must be disconnected before servicing
or cleaning the appliance.

WARNING

DO NOT supply the fryer with a gas that is not indicated
on the data plate. If you need to convert the fryer to
another type of fuel, contact your dealer.

WARNING

The Rethermalizer must be properly restrained to prevent
movement or tipping. This restraint must prevent the unit
from movements that would splash hot liquids on
personnel. This restraint may be by any means (alcove
installation, adequate ties, or battery installation).

WARNING

DO NOT obstruct the flow of combustion/ventila tion or
air openings around the rethermalizer. Adequate
clearance around the rethermalizer is necessary for
servicing and proper burner operation. Ensure that you
meet the minimum clear ances specified in the installation
instructions.

WARNING

The Rethermalizer must be properly restrained to prevent
movement or tipping. This restraint must prevent the
fryer from movements that would splash hot liquids on
personnel. This restraint may be any means (alcove
installation, adequate ties, or battery installation).

WARNING

NEVER supply the Rethermalizer with a gas that is not
indicated on the data plate. Using the incorrect gas type
will cause improper operation. If you need to convert the
unit to another type of fuel, contact your dealer.

THIS MANUAL MUST BE
RETAINED FOR FUTURE

WARNING

Wait 5 minutes before attempting to relight the pilot.
This will allow for any gas in the unit to dissipate.

TROUBLESHOOTING

This section is provided to aid the Authorized Service Technician in the repair of your Rethermalizer.

SYMPTOM POSSIBLE CAUSE

Display will not light Bad Temperature Control, Fuse Holder, Fuse, Transformer or Switch

Maintains wrong temperature Bad Probe or Display

Display lit, but does not heat

Constantly fills, or will not fill

Spark can be heard, Pilot does not light

Pilot Lights but mains do not. Bad Gas Valve or Ignition Module.

Component Diagnosi s:

Before diagnosing any individual components, all appropriate power supplies and wiring terminations must be checked.
Follow the appropriate section below to diagnose the suspected components.

Digital Control:
When 24 VAC is supplied to the Temperature Control, and the control is turned on the display should be lit.
When the water temperature is below the SET Temperature (195°F) 24 VAC Heat Demand signal can be found
between the Gray and Green/Yellow wires at the rear of the controller. The Red LED Heating indicator light will
be ON. When problems with the Temperature Control occur it is important that the Probe be checked also.

Bad K1 Relay, contactor, Probe, Display, Gas Valve or Elements or
Water Level control.

Bad K1 Relay, Level Sensor Seals, Level Control or Water fill solenoid.
Manual bypass valve may be open.

Gas Valve Knob is NOT in the ON position? Plugge Pilot orifice. Bad
Ignition Module or Gas Valve.

Computer Control:
When 24VAC is supplied to the control the display should be lit. When the water temperature is below the SET
Temperature (195°F) a 24VDC Heat Demand signal can be found at the coil of the Heat Demand Relay located
behind the computer.

Water Level Control:
Check for 24 VAC between the COM and 24 V PWR (Power) terminals. Disconnect the HIGH, LOW and COM
terminals, a 24 VAC signal can now be seen between the N.C. and COM terminals. The safety Relay (Kl) and
the Water Fill Solenoid will energize. Using a jumper wire, short the HIGH, LOW and COM terminals together,
this will cause the Control to stop the 24 VAC signal between the N.C. and 24 V PWR terminals.

1

Water Fill Solenoid:

The Water Fill Solenoid should be open when a 24 VAC signal is applied to the two wires leading to the
Actuator. With no voltage present the Solenoid should be closed.

Safety Relay (K1):
With a 24 VAC signal present at the coil section of the relay the switch section should have closed the circuit
between the two Gray wires.

Ignition Control Module:
When the Ignition Control Module receives 24VAC it will send a signal to the spark ignitor at the pilot
assembly. The Module will also send 24VAC to the Pilot Solenoid at the Gas Valve. The pilot will light and
the Pilot Flame Sensor will send a 0.15-0.35 micro amp signal to the Ignition Module at which time the
ignition module will cease the pilot spark and send a 24VAC signal to the Main Solenoid at the Gas Valve. To
test the system look and listen for the above ignition steps and check for the appropriate signals.

Temperature Probe:
Unplug the wiring harness from the rear of the Temperature Control. Measure the resistance between the tw o
black wires on the harness in the cooker, NOT the harness at the control. Measure the water temperature (with
an independent temperature meter or thermometer) and the resistance of the probe at the same time. Consult
the chart below for probe specificati ons.

190°F 8994
195°F 8255
200°F 7585
210°F 6427
212°F 6221

If the resistance varies more than 20% from that specified in the chart the probe should be changed. It is more
important that the probe resistance be correct at 212°F that 70°F, therefore there can be more tolerance given
at 70°F than at 212°F.2
