GPC

Overview

The Frymaster GPC is a gas-fired Pasta Magic cooker for commercial kitchens preparing pasta, ramen, and noodles. A timer controller and automatic fill and skim functions support repeatable cooking and water management during service. The GPC has a cabinet and door.

The GPC belongs to the Pasta Magic gas cooker family, which also includes GPCB, GPCR, and GPCRB models. The GPC is the subject here: it does not have a basket lift, and its manual notes that it does not have a faucet. Basket-lift and rinse-tank features associated with other family models should not be assumed for this unit.

Key Features

• Gas heating: The GPC uses a gas burner system.
• Automatic water functions: Autofill uses water-level sensing to control the water inlet solenoid. The controller also operates the autoskim function.
• Timed control: The controller has a programmable timer, boil and simmer modes, and a skim switch.
• Basket lift: The GPC does not have a basket lift.
• Cabinet construction: The listed configuration includes a cabinet and door.

Installation & Requirements

Location and ventilation

The installation and operation manual specifies indoor use only. For installation next to combustible construction, allow six inches of clearance at both sides and the back. No clearance is required next to noncombustible construction. Provide at least 24 inches of clearance at the front. Keep the areas around the front, sides, and rear clear so air can reach the burners. The cooker needs adequate air supply and ventilation, and the kitchen ventilation system must not create drafts that interfere with burner operation. Install the cooker so combustion products are removed efficiently.

Gas supply

The Pasta Magic gas cooker family is approved for natural gas and propane, but the appliance is configured for a specific gas type. Do not connect it to a different gas supply unless the appropriate conversion components have been installed by qualified, licensed, or authorized service personnel. The manual gives these incoming gas pressure ranges:

• Natural gas: Minimum 6 inches water column; maximum 14 inches water column.
• Propane: Minimum 11 inches water column; maximum 14 inches water column.

The stated burner gas pressures are 3 inches water column for natural gas and 8.25 inches water column for propane. The manual recommends an incoming gas supply line at least 1½ inches in diameter and lists minimum connection piping sizes as follows:

• Natural gas: ¾-inch for one unit; 1 inch for two to three units.
• Propane: ½-inch for one unit; ¾-inch for two to three units.

For gas-line runs longer than 20 feet or with more than four fittings or elbows, the manual says to increase the connection by one pipe size. Before connection, blow new pipe clear of foreign particles. After connecting, check piping and fittings for leaks with a soap solution; never use a match, candle, or other ignition source for a leak check.

Electrical connection

The manuals list GPC component-box assemblies for 120V and 230V and cordsets for 120V and 208–240V. These are component and cordset options, not confirmation of the configuration of a particular unit. Check the equipment identification and wiring diagram before connecting power. The manual states that the wiring diagram is located inside the cooker door and that wiring must follow the diagram supplied with the equipment.

Operation

Controls and cooking modes

The controller panel has a numeric keypad, LED display, power switch, boil-mode switch and indicator, simmer-mode switch and indicator, timer-start switch, skim switch, and trouble light. Set the required cooking time on the controller and press the timer-start switch to begin the countdown. The manual’s troubleshooting guidance specifically recommends confirming that the correct cook time is programmed and pressing Start if the timer does not count down.

In boil mode, the controller calls for heat according to its operating logic and the temperature probe monitors cookpot temperature. In simmer mode, the controller regulates water to the simmer setpoint. The simmer setpoint can be adjusted using the manual’s controller adjustment procedure.

Water level, autofill, and autoskim

The low-water-level sensor must be in contact with water before the control circuit allows the burners to fire. The separate water-level sensor supports autofill: when water falls below the shorter sensor, the controller opens the normally closed water solenoid; when the water reaches that sensor, the controller closes the valve. On units with autoskim, the controller opens the solenoid for three seconds every minute.

The water-level sensors need to be clean and their electrical leads firmly connected. The manual notes that the water must contain some mineral content for the sensors to ground correctly. Distilled, highly filtered, or deionized water may prevent correct operation; if using such water, the manual instructs adding ⅛ cup of baking soda each time the cookpot is emptied and refilled.

Burner ignition

At startup, the controller checks operating conditions, including water level, before enabling the blower and ignition sequence. The ignition module sparks for four seconds to light the burners and verifies flame through the flame sensor. If a burner does not light or its flame goes out, the ignition module stops gas flow and locks out until the controller power switch is turned off and back on. The temperature probe signals the controller as the programmed setpoint is reached, ending the heat cycle.

Cleaning & Maintenance

• Do not use deliming solution: The cooker manual warns that deliming solution damages stainless steel parts.
• Keep water-level sensors clean: Starch or lime deposits can prevent a sensor from grounding and disrupt autofill or burner operation. Check that sensor leads are firmly connected.
• Use the specified water conditions: Water without sufficient mineral content may not conduct as required by the level-sensing system. For distilled, highly filtered, or deionized water, the manual specifies adding ⅛ cup of baking soda whenever the cookpot is emptied and refilled.
• Before moving for service: Drain the cookpot first. The service manual warns that moving the cooker with hot water in it can cause spills or splashing.
• Gas-system work: The manual directs qualified personnel to perform gas service. After gas connections are disturbed, check for leaks using a soap solution, not an open flame.

Troubleshooting

The service manual provides the following checks for common operating problems. Gas, electrical, and internal component repairs should be handled by qualified service personnel where the manual requires it.

• Burner will not light and trouble light is on: Check whether the cooker gas valve is off or the incoming gas shutoff valve is closed. Open the appropriate valve if it has been shut off.
• Burner will not light, trouble light is off, and blower is not running: The manual identifies a failed 24VAC blower relay or controller as possible causes. It specifies checking for 24VAC at pin 4 of the 15-pin connector; if voltage is present, replace the relay. If the relay is not the cause, the controller may have failed.
• Trouble light is on and blower runs continuously: A failed blower centrifugal switch, ignition module, or gas valve may be responsible. The manual specifies checking for 24VAC at the ignition module and checking for module output to the gas valve and a spark at the ignitor.
• Burner makes a popping sound on ignition: The listed causes are a dirty blower inlet or fan, a clogged gas-valve vent tube, cracked or broken burner ceramic, or a failed ignitor. The manual’s corrective actions include cleaning the blower, cleaning the vent tube, or replacing the affected burner or ignitor.
• Controller display is blank: Check that the controller is on, the power cord is plugged into the appropriate outlet, and the main circuit breaker has not tripped. The manual also lists a failed transformer or controller; it directs checking for 24VAC on the transformer secondary.
• Controller does not count down: Confirm that the correct cook time is programmed and press the Start button. If the timer still does not count down, the manual identifies the controller as a possible failure.
• Water boils in simmer mode: A failed or shorted temperature probe is a possible cause. The manual gives approximate probe resistance of 552 ohms at 60°F, 655 ohms at 100°F, and 1,000 ohms at 212°F; replace the probe if its resistance is out of specification.
• Water temperature is too low in simmer mode: The manual lists an out-of-calibration controller or an open temperature probe. Recalibrate the simmer setpoint as directed, check probe connections, and replace the probe if the connections are secure but the fault remains.

Applications

The GPC suits restaurant and foodservice kitchens that cook pasta, ramen, or noodles in batches. Its timed controls, gas-fired water heating, and automatic water-level functions are relevant for pasta stations preparing menu items throughout service. The product is a water cooker, not a fryer.
