2.3 Installation Instructions

2.3.1 General Installation Requirements

PROPER INSTALLATION IS ESSENTIAL FOR EFFICIENT, TROUBLE-FREE

OPERATION OF YOUR RETHERMALIZER. ANY UNAUTHORIZED ALTERATIONS

MADE TO THIS EQUIPMENT WILL VOID THE FRYMASTER WARRANTY.

Upon arrival, inspect the rethermalizer carefully for visible or concealed damage. (See Shipping

Damage Claim Procedure in Chapter 1.)

CLEARANCE AND VENTILATION

This equipment must be installed with a 6” (150mm) clearance at both sides and back when installed

adjacent to combustible construction. No clearance is required when installed adjacent to

noncombustible construction. A minimum of 24” (600mm) clearance should be provided at the

front of the unit.

2-3

2.3.1 General Installation Requirements (cont.)

One of the most important considerations of efficient operation is ventilation. Make sure the

equipment is installed so that products of combustion are removed efficiently, and that the kitchen

ventilation system does not produce drafts that interfere with proper burner operation.

The equipment flue opening must not be placed close to the intake of the exhaust fan, and the flue

must never be extended in a “chimney” fashion. An extended flue will change the combustion

characteristics of the equipment, causing longer recovery times. It also frequently causes delayed

ignition. To provide the airflow necessary for good combustion and burner operation, the areas

surrounding the front, sides, and rear of the unit must be kept clear and unobstructed.

This equipment must be installed in an area with an adequate air supply and adequate ventilation.

For U.S installations, information on construction and installation of ventilating hoods can be found

in NFPA Standard 96. This document can be ordered from the National Fire Protection Association,

Battery March Park, Quincy, MA 02269. For installations in countries other than the U.S., the

appropriate regulating authority should be contacted for information related to hood construction and

installation.

DANGER

Do not attach an apron drain to a single rethermalizer. The rethermalizer may

become unstable, tip over, and cause injury to personnel.

NATIONAL CODE REQUIREMENTS

This equipment is to be installed in compliance with the Basic Plumbing Code of the Building

Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation

Manual of the U.S. Food and Drug Administration.

This equipment is manufactured to use the type of gas specified on the rating plate attached to the

door. Connect equipment stamped “NAT” only to natural gas and that stamped “PRO” only to LP

(Propane) gas.

Installation shall be made with a gas connector that complies with national and local codes. Quick

disconnect devices, if used, shall likewise comply with national and local codes.

ELECTRICAL GROUNDING REQUIREMENTS

All electrically operated appliances must be grounded in accordance with all applicable national and

local codes. A wiring diagram is located on the inside of the door. In the United States and Canada,

the electrical supply must be 120VAC, 60 Hz. In other countries, refer to the rating plate on the

inside of the door for proper voltages.

2.4.1 Connecting to the Gas Supply

GAS CONNECTIONS AND PIPE SIZES

The size of the gas supply pipe is very important. If the pipe is too small, the gas pressure at the

burner manifold will be low. This will cause slow recovery and delayed ignition. The incoming gas

supply line should be a minimum of 1½ inches (38mm) ID.

2-6

2.4.1 Connecting to the Gas Supply (cont.)

When configured for natural gas, this equipment requires a standard gas pipe size of ¾ inch (22 mm)

ID for connections within 20 feet (6 m) of the supply line, provided no more than 4 fittings or

elbows are used in the run. For a pipe run over 20 feet (6 m), increase the pipe size to 1 inch (28

mm). For use with LP (Propane) gas, the next smaller pipe size may be used.

IF IN DOUBT ABOUT THE PIPE SIZE TO BE USED, CONSULT YOUR LOCAL GAS

COMPANY.

DANGER

Before connecting new pipe to this equipment, the pipe must be blown out

thoroughly to remove all foreign material. Foreign material in the burner and gas

controls may cause improper and dangerous operation.

1. Connect the equipment to the gas supply line. When making connections, apply a small amount

of Loctitite® PST 56765 or equivalent thread compound to the male threads only. DO NOT

apply the compound to the first two threads. This will prevent clogging of the burner orifices

and control valve.

2. Open the gas supply to the fryer and check all piping, fittings, and gas connections for leaks. A

soap-and-water solution should be used for this purpose. NEVER USE OPEN FLAME TO

CHECK FOR GAS LEAKS.

DANGER

3.5 Computer Operation (cont.)

The FGP55 CM-III.5 computer has 10 programmable product buttons, a Simmer Mode switch, and a

Boil Mode switch. The computer also has two Power switches. Either switch may be pressed to

turn the unit ON or OFF.

The product buttons are multi-functional. In the programming mode, each button can be

programmed for a distinct rethermalizing time for a particular product. In the rethermalizing mode,

pressing a button initiates a timed countdown of the specific product associated with the button.

When the switch is pressed, the programmed setpoint is overridden and the vessel temperature is

raised to and maintained at 212°F (100°C). When the unit is in boil mode, appears in both

LED displays. The unit will remain in the boil mode until the Simmer Mode switch is pressed or the

unit is turned off.

The Simmer Mode is activated by pressing the (R) switch. In Simmer Mode, the vessel

temperature is maintained at the programmed setpoint. When the switch is pressed, if the vessel

temperature is above the setpoint, °- is displayed in both LED widows. If the vessel

temperature is below the setpoint, °- is displayed. If the temperature is within 11°F (6°C) of the

setpoint, (four dashes) is displayed.

3.6 Programming the FGP55 CM-III.5 Computer

CAUTION

It is recommended that the simmer setpoint and the heat/stir times for all 10

products be programmed before the unit is first used in a rethermalizing cycle.

When the unit is tested at the factory, the simmer setpoint and product rethermalizing times are

programmed. These test settings are not default settings. You must program the unit for your own

particular products. Program the setpoint and all product rethermalizing times as follows:

1. Turn the computer on by pressing the switch.

2. Enter the programming mode by pressing the switch. appears in the left display. If

you enter the programming mode by mistake, press the switch again to exit the programming

mode

the new display option.

3. Enter the number 1 6 5 0 by pressing the corresponding product buttons. The computer

cannot be programmed unless this code is entered, thus preventing any unauthorized changes to

current program instructions.

4. (Setpoint) will appear in the left LED display. Any previously programmed temperature

setpoint will appear in the right display. To change the setpoint, enter the desired setpoint

temperature using the corresponding product buttons. The setpoint can be programmed for any

value up to 212°F (100°C). Press the Program Mode switch to lock in the new setpoint (or

the old setpoint, if it was not changed).

5. (Select Product) will appear in the left display. Press the product button to be

programmed (or press to return to the normal operating mode).

6. (Rethermalizing Time) will now show in the left display. Any previously programmed

rethermalizing time will appear in the right display. Pressing will accept the current

rethermalizing time. To change the rethermalizing time, enter the new time using the product

buttons. The rethermalizing time can be programmed up to 59:59. Press to lock in the new

time.

NOTE: The computer can be programmed for either "standard" or "slow" clock. The standard

clock displays minutes and seconds, the slow clock displays hours and minutes. To toggle

between times press the switch, then enter the code 1 6 5 3 using the product buttons.

Press the switch to lock in the clock speed. To determine whether the clock speed is set to

standard or slow, initiate a rethermalizing cycle by pressing a product button. If the computer is

set to the standard clock, the time in the LED display will immediately begin to count down. If

countdown does not begin immediately, the computer is set to the slow clock.

7. SH1 (Stir Time 1) appears in the left display. If your product requires stirring during the

rethermalizing process, set the number of seconds to heat before stirring using the product

buttons. If your product does not require stirring, enter "0". The number entered will appear in

the right display. The stir time can be programmed up to 59:59, but must not exceed the

product rethermalizing time. Press to lock in the programmed time.

For example, entering "30" means the product needs to be stirred after it has been rethermalizing

for thirty seconds. At the end of thirty seconds, an alarm will sound and the product switch will

flash until cancelled by the operator pressing the product button.

3.6 Programming the FGP55 CM-III.5 Computer (cont.)

SH2 will appear. Program the length of the second stir time as above being sure that the time

entered is greater than that for stir time "1" or else is "0".

SH3 will appear. Program the length of the third stir time in the same manner as for stir times

"1" and "2", being sure that the time entered is greater than that for stir time "2" or else is "0".

CAUTION

Remember: Stir time "2" must be greater than stir time "1" (or else be "0"). Stir time

"3" must be greater than stir time "2" (or else be "0"). None of the stir times should

be greater than the rethermalizing time entered in Step 6. If a stir time exceeds the

rethermalizing time, the stir time will be ignored.

8. (Select Product) will again appear in the left display. If more products are to be

programmed, return to Step 5 and follow all instructions to this point, repeating for each product.
