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.

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.

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.

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 Loctite® 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
Never use matches, candles, or any other ignition source to check for leaks.

If gas odors are detected, shut off the gas supply to the fryer at the main shut-off valve and contact the local gas company or an authorized service agency for service.

The rethermalizer and any shut-off valves installed between the rethermalizer and the gas supply line must be disconnected from the gas supply line during any pressure testing of the supply line at pressures equal to or greater than ½ PSIG (3.45kPa, 14 inches W.C.).

3. Close the drain valve and press the power button into the ON position. The pot will automatically begin to fill and the burners will light when the lower float switch is satisfied. Perform the boil-out procedures as described in Section 2.6, “Boil-Out Instructions” in this manual.
4. It is suggested that the burner manifold pressure be checked at this time by the local gas company or an authorized service agent.

2.5 Converting to Another Gas Type

This equipment is configured at the factory for either natural gas or LP (propane) gas.

If you desire to switch from one type of gas to the other, a gas conversion kit must be installed by a Factory Authorized Servicer.

DANGER
Switching to a different type of gas without installing the proper conversion kit may result in fire or explosion! NEVER attach your fryer to a gas supply for which it is not configured.

CHAPTER 5: Troubleshooting

5.1 Introduction

This chapter provides an easy reference guide to the more common problems that may occur during the operation of this equipment. The troubleshooting guides in this chapter are intended to help you correct, or at least accurately diagnose, problems with the equipment. Although the chapter covers the most common problems reported, you may very well encounter a problem not covered. In such instances, the Frymaster Technical Service Department will make every effort to help you identify and resolve the problem.

When troubleshooting a problem, always use a process of elimination starting with the simplest solution and working through to the most complex. Never overlook the obvious. Anyone can forget to plug a cord into a receptacle or open the valve on the water supply line. Don’t assume that you are exempt from such occurrences. Most importantly, try to establish a clear idea of why a problem has occurred. Part of your corrective action involves taking steps to ensure that it doesn’t happen again. Keep in mind that failure of a small component may often be indicative of potential failure or incorrect functioning of a more important component or system.

If the troubleshooting and corrective actions in this chapter do not solve the problem, the problem is probably beyond the scope of most operators and you should call your Factory Authorized Servicer for assistance. If you have doubts as to the proper action to take, do not hesitate to call the Frymaster Technical Service Department or your local Frymaster Factory Authorized Servicer for assistance.

Before calling a servicer or the Frymaster HOTLINE (1-800-551-8633):

• Verify that electrical cords are plugged in and that circuit breakers are on.
• Verify that water supply valves are open and that drain valves are fully closed.

DANGER
Hot water can cause severe burns. Never attempt to move this equipment when filled with hot water or to transfer hot water from one container to another.

DANGER
