Chapter 1: General Information and Installation

The Pitco Frialator Rethermalizer is a revolutionary new reheating unit. By using Pitco Frialator's tube fired heating
system, the Rethermalizer is up to temperature and ready to cook in minutes. Each of the heating tanks holds
approximately 15 gallons of water which is maintained automatically by the unit. The temperature of each tank is
monitored and controlled by its own electronic unit mounted in the front panel. Each electronic unit is preset at the
factory to maintain the temperature of its tank at 195 °F. Quick recovery time and even temperatures are assured by using
a 55,000 BTU main burner system for each tank. The Rethermalizer is very easy to use allowing you to cook and not
worry about the unit. How ever, it is important that you familiarize yourself with the operation and safety notices of this
manual. This manual contains the installation, operation, and maintenance procedures for the Taco Bell Rethermalizer.
Do not throw away this manual after use, store in a safe place for reference.

1.1 CHECKING YOUR NEW RETHERMALIZER

Every effort has been made to ensure that your Rethermalizer will be delivered to you in perfect condition. As you
unpack the Rethermalizer, inspect the unit for damage. If somethi ng is damaged, DO NOT sign the bill of lading. Contact
the shipper immediately, because the shipper is only responsible for 15 days after delivery. Check the packing list
enclosed with your Rethermalizer to ensure that you have received everything on the list. If you are missing any parts,
contact the dealer from whom the unit was purchased. As you unpack the Rethermalizer be careful to keep its weight
evenly distributed.

Flue Vents

CAUTION

To prevent equipment damage, don't tilt the unit onto any three
of its casters or pull the unit by the flue vents.

Locate your Pitco Frialator warranty and fill in the serial number of the Rethermalizer and the date received. You will
find the serial number on the plate inside the door. Put your warranty in a safe pl ace for future reference. DO NOT return
the warranty sheet to Pitco Frialator. The Rethermalizer has been assembled for you at the factory and is ready to be
installed.

1.2 ASSEMBLY AND LEVELING

When you receive your Rethermalizer it is completely assembled with the possible exception of the casters.

1.2.1 Caster Installation and Adjustment

Installing the casters on the Rethermalizer is done with a 7/16" wrench and socket. The casters must be installed before
connecting the unit to the gas supply. The casters provide the necessary height to meet sanitation requirements and assure
adequate air supply to the burner. Attach the casters by performing the following procedure.

a. Lay the Rethermalizer on its back being careful not to damage the flue by pulling on it. Protect the outside

of the unit with cardboard or a drop cloth when laying it down.

b. Attach each caster with the hex head cap nut supplied with the

Rethermalizer. Each caster requires four 1/4-20 x 5/8" bolt.

c. Mount the bolts from the inside of the unit with the nut on the outside of

the cooker. The nuts have lock washers attached to them, therefore it is not
necessary to use lock washers.

d. When all six casters are mounted, stand the unit up being careful not to put

too much weight on any one caster.

e. Move the Rethermalizer to the desired location and lock the wheels using

the front locking devices on each caster.

1.3 INSTALLATION

Although it is possible for you to install and set up your new Rethermalizer, it is STRONGLY recommended that you
have it done by qualified professionals. The professionals that install your new Rethermalizer will know the local
building codes and ensure that your installation is safe. This manual provides the installer with valuable information on
the installation of your Rethermalizer.

WARNING

DO NOT obstruct the flow of combustion/ventilation 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 clearances specified in the
installation instructions.

1-2

1.3.1 Installation Clearances
The Rethermalizer needs clearance around it for proper operation. Adequate clearances allow for servicing

and proper burner operation. The clearances shown below are for cooker installation in combustible and non­combustible construction.

Back 6" 0"
Sides 6" 0"
Floor 4" 4"

Combustible Non-Combustible
Construction Construction

1.3.2 Gas Connection
Your Rethermalizer will give you peak performance when the gas supply line is of sufficient size to provide

the correct gas flow. The gas line must be installed to meet the local building codes or National Fuel Gas
Code (NFPA 54-1984) and ANSI Z223.1-1988 (or most current). In Canada, install the Rethermalizer in
accordance with CAN1-B 149.1 and CAN1-B 149.2 and local codes. Gas line sizing requirements can be
determined by your local gas company by referring to National Fuel Gas Code, Appendix C, Table C-4
(natural gas) and Table C-16 (propane). The gas line must be large enough to supply the necessary amount
of fuel to all appliances. The burner manifold operating pressure should be as specified on the data plate
attached to the inside of the door. Other factors that are used to determine the piping requirements are BTU
requirements of the appliances being connected and the length of pipe between the meter (main shut off) and
the appliances.

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.

1.3.2.1 Fuel Types - Each Rethermalizer is equipped to work with one type of fuel. The type of fuel with
which the appliance is intended to operate is stamped on the data plate attached to the inside of the
door.

WARNING

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

1.3.2.2 Gas Line Connection - Connect the Rethermalizer to the gas supply line with a connector that
complies with the Standard for Connectors for Movable Gas Appliances (ANSI Z21. 69-1987). If
you are installing a unit with casters use a quick disconnect discussed in the Quick Disconnect
installation instruction, 1.3.2.3. Connect the gas line to the Rethermalizer using a pipe joint sealant
that is resistant to liquefied petroleum. If the Rethermalizer was disconnected during the fuel line
testing, use a solution of soap and water to leak test the new connection.

1-3

NOTICE

NEVER use an adaptor to make a smaller gas supply line fit the cooker connection.
This may not allow proper gas flow for optimum burner operation, resulting in poor
cooker performance.

1.3.2.3 Quick Disconnect Gas Connection - Units
equipped with casters must be installed with connectors that
comply with the Standard for Connectors for Movable Gas
Appliances, ANSI Z21.69-1987, and Addenda Z21.69A-

1989. This connection should include a quick disconnect
device that complies with the Standard for Quick
Disconnect Devices for Use With Gas Fuel , ANSI Z21.41-

1989. When installing a quick disconnect you must also
install a means for limiting the movement of the
rethermalizer. This device will prevent the gas line or the
quick disconnect from being strained. The restraining device
should be attached to the cooker on the back panel as shown
in the illustration. The quick disconnect, hose, and
restraining device can be obtained from your dealer.

1.3.2.4 Fuel Supply Line Leak and Pressure Testing - The fuel supply system must be tested before the
Rethermalizer is used. If the fuel line is going to be tested at a pressure greater than (>) 1/2 PSIG (3.45 kPa),
make sure that the unit is disconnected from the fuel line. If the fuel line is to be tested at a pressure equal to or
less than (<) 1/2 PSIG (3.45 kPa), the Rethermalizer can be connected but the unit's gas valve must be shut.
Test all gas line connections for leaks with a solution of soap and water when pressure is applied.

1.3.3 Plumbing Connections
The plumbing installation should be done by a licensed plumber and must comply with local and national

codes. The water inlet line on the Rethermalizer is located on the back side of the unit and consists of a hose
with a quick disconnect similar to that used for the gas connection. This line feeds water to the auto fill valves
through the manual shut-off valves also located on the back of the unit. A drain line for each tank is
underneath the unit and can be inserted into a drainage system. The drain lines for each tank are connected
together to form a single common drain line. The drain line also has the overflow line from each tank
connected to it. This connection is made after the drain valve to provide an unobstructed overflow path.

1-4

1.3.4 Electrical Connection
The electrical service used by the Rethermalizer must comply with local codes. If there are no local codes

that apply, refer to the National Electrical Code (NEC) to install the service. In Canada refer to CSA
Standard C22. 1 and local codes. Wiring diagrams are provided inside the front panel of the Rethermalizer.
The power requirements for the unit are shown below.

Input Voltage 120 VAC, 60Hz
Current per Rethermalizer 0.5 Amps

WARNING

This appliance is equipped with a three prong (grounding) plug for your protection
against electrical shock hazard in the event of equipment malfunc tion. DO NOT cut
or remove the grounding (third) prong.

The Rethermalizer has two power cords which supplies power to the unit's controls. The unit must be
grounded in accordance with local code; if there is not a local code, comply with NEC ANSI/NFPA No. 70-

1987. It is advised that these power cords be plugged into a wall receptacle supplied from the ventilation
control. This will ensure that the Rethermalizer can not be operated unless the ventilator is also on to provide
proper ventilation. Disconnect power to the Rethermalizer before cleaning or servicing.

1.3.5 Ventilation and Fire Safety Systems
Your new Rethermalizer must have prope r ventilation to function safely and properly. Exhaust gas

temperatures can reach as high as 1200°F. Therefore, it is very important to install a fire safety system. Your
ventilation system should be designed to allow for easy cleaning. Frequent cleaning of the ventilation system
and the Rethermalizer will reduce the chances of fire. Table 1-1 provides a list of reference documents that
provide guidance on ventilation and fire safety systems. This table is not necessarily complete. Additional
information can be obtained from the American Gas Association, 8501 East Pleasant Valley Road,
Cleveland, OH 44131.

WARNING

Never stand on the rethermalizer to service or clean the hood.

1-5

CAUTION

Underwriters Laboratory

es of Fire Extingushers

Ensure that your ventilation system does not cause a back draft (down draft) at the
unit's flue opening. Back drafts will not allow the Rethermalizer to exhaust properly
and will cause overheating which may cause permanent damage. Damage caused by
backdrafts will not be covered under equipment warranty. NEVER allow anything to
obstruct the flow of combustibles or ventilation exiting from the unit's flue. DO NOT
put anything on top of the flue area.

Excessive ventilation causes drafts, which will interfere with the proper operation of the pilot and the
burner. Leave at least 18 inches of open space between the Rethermalizer's flue vent opening and the intake
of the exhaust hood.

NEVER connect the blower hood vent directly to the flue openings. The direct flow
of air will cause poor temperature recovery, poor ignition, inefficient operation of the
Rethermalizer, and could extinguish the pilot.

NOTICE

1.4 INITIAL ADJUSTMENTS
After your Rethermalizer has been installed as described in section 1.3, it needs to be adjusted to ensure that

it will perform as designed. These adjustments must be performed by a qualified person. To perform these
adjustments the following tools will be needed:

• Manometer (low pressure gauge) • DC Millivolt Meter

1.4.1 Visual Checks and Equipment Locations

Before you begin filling and adjusting the unit, perform the following visual checks:

a. Move the Rethe rmalizer to its permanent cooking position and lock the caster wheels. Ensure that

the Rethermalizer drain is lined up with the floor drain.

b. Check the High Limit probe located inside the tank. Ensure that the mounting screws are tight to

prevent the pr obe from coming loose during operation. Figure 1-1 shows the location of the
High Limit probe, Temperature probe, and the Water Level sensors. Also shown are the over
flow stand pipe and the water entry nozzle. Look down inside the Rethermalizer tanks to see the
probes.

Figure 1-1 Component Locations, Inside Tank

1-7

1.4.2 Filling the Rethermalizer
The Rethermalizer is equipped with an automatic water level

maintaining system. To fill the unit with water place the ON/ OFF
switch in the ON position. This causes the solenoid valve to open
and supply water to the unit through the fill nozzle in the bottom of
the tank. The tank will continue to fill until the water level reaches
the level sensors. When both water level sensors are covered the
solenoid valve will close stopping the flow of water. During
normal operation the automatic fill system will maintain the water level at the proper height.

NOTE

During normal operation the automatic water fill system will continue to control the
water level in the Rethermalizer tank. If the water control system turns on while the
main burners are lit the main burners will turn off. This is normal and will not affect
the operation of the Rethermalizer. When the tank refills to the high level probe the
solenoid will close and the main burners will relight.

1.4.3 Pilot Light System
The Rethermalizer uses a manual pilot light system to light the main burners. The pilot light receives its gas

supply through the electrically controlled gas valve. To light the pilot, perform the procedure below.

a. Each side of the unit has its own gas supply valve. This allows one side to be serviced while the

other is operating. These gas valves should normally be open.

b. Turn the gas valve knob to the PILOT position and push in on the knob. Hold

the knob in for approximately one minute to purge the air out of the line. Hold
a flame to the pilot light until the pilot ignites. This may take a little while the
first time you light the Rethermalizer because of air in the lines. Once lit, hold
the knob in for approximately 60 seconds and then release.

WARNING

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

c. Turn the gas knob counterclockwise to the ON position.

1-8

d. If the pilot goes out repeat step c. If after three tries the pilot will not remain lit, contact a

qualified service technician.

e. Place the ON/OFF switch in the ON position. The

electronic control unit will come on and display the
temperature of the water. There will also be a red light lit
between the left and middle digits of the display. This
light indicates that the electronic control unit is calling
for heat. If the water level is below the low level sensor
the water solenoid valve will open and fill the tank.

f. When the water in the tank is at the

correct level the main burner will light
and be controlled by the electronic
control unit. The pilot burner will
remain lit regardless of the switch
position.

g. The burners will remain lit until the

temperature reaches 195°F where they
will turn off. While the burners are off
the red light in the electronic display
will be off. The burners will maintain
the water temperature be tween 194°F
and 196°F.

h. When the ON/OFF switch is in the ON posit ion the water level will be maintained by the water fill

system.

1.4.3.1 Pilot Flame Adjustment - The pilot flame should be adjusted to produce between 300 and 500
millivolts output from the thermopile. Figure 1-2 shows the pilot assembly with examples of the incorrect
and correct pilot size. Example A illustrates a pilot size that is too small to produce sufficient millivolt
output. Example B is the correct size for proper millivolt output.

Figure 1-2 Pilot Assembly, Flame Adjustment

1-9

a. This test requires the DC millivolt meter set to a scale of 0-l000mV. Using leads with sharp probes

will help in taking the required reading.

b. Locate the thermopile wires coming from the High Limit box going to the gas shut off valve. The

wire insulation size decreases near the gas valve connections.

c. Connect the negative (-) test probe to the pilot tubing (ground).

d. Connect the positive (+) test probe to one of the High Temperature Limit terminal connections.

e. Remove the pilot flame adjustment cover.

Figure 1-3 Gas Valve Showing Location of the Pressure Regulator and Pilot Adjusters.

f. Turning the flame adjusting screw clockwise lowers the flame and the millivolt output. Turning the

screw counterclockwise increases flame size and millivolt output.

g. Rotate the screw in the direction to achieve a reading of 400±50 mV.

NOTE

Allow 3 to 5 minutes between flame adjustments to allow the reading to settle.

h. Replace the pilot flame adjusting screw cover.

1-10

1.4.4 Main Burner System

For the burners to work the gas supply valve must be open and the main power switch must be on. The main
burners receive gas from the main gas supply through the electric control valve. When the electronic control
unit calls for he at (and the tank is at the proper water level), the gas control valve opens. After the burner
system is operating, perform the burner adjustments in the following procedure. Figure 1-4 illustrates the
different conditions possible for the main burner.

The tubes and baffles are badly
carbonized. Check vent and
adjust if necessary. Check for
heat tube or flue blockage.

INSUFFICIENT FLOW

Have gas company check
incoming gas pressure. Adjust
manifold pressure as described in

1.4.3.2.

The flame seems to "lift off the
face of the burner. To correct
adjust main burner as
described in 1.4.3.2.

1.4.4.1 Gas Line Requirements - A properly installed gas supply system will deliver 7.0 ±2.0" w.c. natural

gas (12.0 ±2.0" w.c. LP) to all appliances connected to the line, operating at full demand.

1.4.4.2 Burner Adjustment - The burners must be adjusted to deliver optimum flame. Adjust the burner

flame using the following procedure.

a. Ensure that the gas control valve is in the PILOT position. Remove the manifold pressure tap

plug and connect an accurate pressure gauge (range of 0-16" w.c. in 0.1" increments) or
manometer.

b. Light the pilot burner for the unit being tested and place the

ON/OFF switch in On to light the main burners.

c. The installed pressure gauge reading should be the same, ±0.1",

as that marked on the data plate insid e the door. If the pressure
is correct go to step e, if not, adjust the pressure.

d. To adjust the pressure, remove the regulator adjustment screw

cover (see Figure 1-3). Use a flat tip screwdriver to adjust the screw until the proper pressure is
reached. Turning the screw clockwise will increase the pressure, counterclockwise will decrease
the pressure.

e. When the pressure is correct, install the regulator adjustment screw cover.

f. To remove the pressure gauge, turn the gas control valve to PILOT. Remove the gauge and install

the pressure tap plug.

g. Now that the pressure is set for proper operation, set the main burner flame. Unlock the air collars

by loosening the set screw for the collars. Turn the gas control valve to ON and place the
ON/OFF switch in ON to light the main burners.

h. Adjust the shape and size by raising or lowering the air collars to achieve a soft blue flame with

well defined inner cones.

Chapter 2: Operating Instructions

This chapter describes how to operate your Rethermalizer to obtain the best performance. Included in this
chapter are filling, operating, and cleaning instructions.

2.1 FILLING THE RETHERMALIZER
The Rethermalizer is equip ped with an automatic water level maintaining system. To fill the unit with water

place the ON/OFF switch in ON. This causes the solenoid valve to open and supply water to the unit
through the fill nozzle in the bottom of the tank. The tank will continue to fill until the water level reaches
the level sensors. When both water level sensors are covered the solenoid valve will close stopping the flow
of water. During normal operation the automatic fill system will maintain the water level at the proper
height.

NOTE

During normal operation the automatic water fill system will continue to control the
water level in the Rethermalizer tank. If the water control system turns on while the
main burners are lit the main burners will turn off. This is normal and will not affect
the operation of the Rethermalizer. When the tank refills to the high level probe the
solenoid will close and the main burners will relight.

2.1.1 Manual Operation of The Water Fill System

CAUTION

When the water solenoid is by-passed the automatic water fill system WILL NOT
maintain the water level. The water level control system should remain in automatic
during normal operation.

Although the water fill system is completely automatic, the solenoid valve can be by-passed manually to fill
the tank. To by-pass the water solenoid valve open the valve in the by-pass pipe. This should only be done if
the solenoid valve fails and the Rethermalizer needs to be operated. When finished filling the Rethermalizer
ensure that the solenoid manual by-pass valve is returned to its normal position.

3-1

3.2 FLUE AND BAFFLE INSPECTION
It is recommended that once every six months with the cooker cooled down you examine the flue area and

the burner tube baffles. Check for corrosion or blockage of the flue and erosion of the baffles. The burners
should be removed to thoroughly inspect the baffles. If necessary clean the heat tube area and replace the
baffles if they are eroded or distorted. Ensure that the cooker is shutdown and do not turn it on during the
examination. Examination of the flue area during cooking may cause bodily injury.

3.3 SERVICE
If servicing is required, electrical components can be accessed through the front panel. To gain access to the

front panel electrical components, remove the four screws on the front panel. Remove the front panel and
set aside with the four screws for installation after servicing is complete. An electrical diagram is supplied
inside the front panel for use by an authorized service person. There is also an electrical diagram in the back
of this manual. The electrical diagram can be used to verify the proper operation of the electrical systems.
After servicing is complete, the diagram should be replaced for future reference and the front panel
installed.

To prevent bums, always ensure that the unit is completely SHUT DOWN and
COOLED down before working on the Rethermalizer. Do not break any gas
connections while the unit is connected to a gas supply line.

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

NOTICE

The unit has casters and therefore has a quick disconnect gas connection and a
restraining device. Care should be exercised when moving the unit out to be
serviced. When you are moving the unit back into place ensure that you connect the
restraining device before you move the unit back into place. You should also be
careful not to kink the gas or water hose.

3.3.2 Temperature Controller Calibration

The temperature controller does not need routine calibration. It will maintain its factory set calibration
during normal operations. In some instances if the controller receives a static charge it can become erratic.
Static charge can scramble the controllers program. If this should happen, first try to correct the problem by
draining the tank and allowing it to refill with cool water. This will drop the temperature of the water well
below the normal operating te mperature and may reset the controller program. If this does not reset the
controller, perform the calibration procedure below.

a. Gain access to the rear of the controller by removing the front panel of the rethermalizer.

b. Install a jumper between the +5 and -3 volt terminals. This enables the controls on the front of the

controller.

NOTE

If during the setting procedure you stop for longer than 15 seconds the controller will
revert to the temperature display mode WITHOUT changing its settings.

c. Adjust the differential temperature limit by pressing the °F switch. The display will show dFl.

Press °F again to display the differential setting. For proper operation this number must be a
positive valve. Use the up or down Adjust keys to set the differential number.

d. Press the °F key until the display goes blank. This completes the differential adjustment.

e. To set the setpoint of the controller press the SET key. The display will show SP 1. Press the SET

key again to display the current setting.
