Service Hotline at 1-888-875-2722. DANGER The front ledge of the fryer is not a step! Do not stand on the fryer. Serious injury can result from slips or contact with the hot oil.
  • Page 4 18 in. (450 mm) should be maintained between the flue outlet and the lower edge of the grease filter.” The Montague Co. recommends that the minimum distance be 24 in. (600 mm) from the flue outlet to the bottom edge of the filter when the appliance consumes more than 120,000 BTUs per hour .
  • Page 5 INSTALLATION ALL DEEP FAT FRYERS MUST BE INSTALLED WITH AT LEAST A 16 INCH SPACE BETWEEN THE FRYER AND SURFACE FLAMES FROM ANY ADJACENT COOKING EQUIPMENT. A minimum of 24" should be provided at the front of the unit for servicing and proper operation.
  • Page 6 INSTALLATION CURB INSTALLATION: Place shim under the low side. This operation is impor- tant since variation in floor and curbs are common. Unless ranges are level, difficulty will be encountered in aligning the gas supply manifold and the ranges will not butt together tightly. Remove the upper valve panel from the fryer.
  • Page 7 Montague recommends that the minimum distance from the flue outlet to the bottom edge of the filter be 24 in. (600 mm) when the appliance consumes more than 120,000 BTU per hour.
  • Page 8 INSTALLATION Connection to Gas Line The size of the gas line used for installation is very important. If the line is too small, the gas pressure at the burner manifold will be low. This may cause pilot outage, slow recovery and delayed ignition.

  • Page 9: Installation

    INSTALLATION Before connecting new pipe to your unit, the pipe must be thoroughly blown out to remove any foreign particles. If these foreign particles get into the burner and controls, they will cause improper and sometimes dangerous operation. 1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting under the front of the fryer and to the building gas line.
  • Page 10 Your fryer is configured at the factory for either natural gas or Propane (LP) gas. If you desire to switch from one type of gas to another, a gas conversion kit must be installed by a Montague Company Authorized Service techni cian. DANGER...
  • Page 11 INSTALLATION GAS CONNECTION Before connecting the range and fryer battery to the gas supply line, be sure that all new piping has been cleaned and purged to prevent any foreign matter from being carried into the controls by the gas. In some cases, filters or drops are recommended. A separate Gas Shut Off Valve must be installed upstream from the range and fryer battery and located in an accessible area.

  • Page 14 INSTALLATION DANGER Never leave the fryer unattended during the boil-out process. If the boil-out solution boils over, turn the fryer off immediately and let the solution cool for a few minutes before resuming the process. 1. Before operating the burner, close fryer drain valve and fill empty frypot with a mixture of cold water and boil-out solution.
  • Page 15 INSTALLATION 4. To melt solid shortening without scorching, the burner should be turned ON for about three seconds and OFF for about 10 seconds; alternate until melted. If any smoke is seen during this process, the oil is heating too quickly and scorching. This melting process is not necessary with liquid shortening.

  • Page 16: Operation

    OPERATION For maximum frying compound life, good operators find they do best by frying at the lowest temperature that will give a high-quality product. Thus with a super-fast fryer, such as yours, you do not have to fry potatoes at 375° or 400°, you fry at 325°. A little experimenting will determine just the right temperatures for your menu items.
  • Page 17 OPERATION Draining and Manual Filtering DANGER Allow oil/shortening to cool to 100ºF (38ºC) or lower before draining to an appropriate container for disposal. The cooking oil or shortening must be drained into another suitable container. FOR SAFE, CONVENIENT DRAINING AND DISPOSAL OF USED COOKING OIL OR SHORTENING, FRYMASTER RECOMMENDS THE USE OF THE FRYMASTER SHORTENING DISPOSAL UNIT (SDU).

  • Page 18: Maintenance

    MAINTENANCE EXTERIOR Painted Surface: Allow equipment to cool after use and wash with a mild detergent or soap solution. Dry thoroughly with a dry cloth. Stainless Steel Surface: To remove dirt grease or product residue from stainless steel, use ordinary soap and water (with or without detergent) applied with a sponge or cloth. Dry thor- oughly with a clean cloth.
  • Page 19 Inspect the ceramic burner targets. Ensure the targets are in position above each orifice, and that the flame ignites approximately 2½ inches (60mm) above the orifice. The flame should strike the center of the target and be a rich blue color. Call your Montague Company Autho- rized Service Agency if you see any problems.
  • Page 20 MAINTENANCE The cooking oil or shortening must be drained into another suitable container. FOR SAFE, CONVENIENT DRAINING AND DISPOSAL OF USED COOKING OIL OR SHORTENING, FRYMASTERRECOMMENDS THE USE OF OUR SHORTENING DISPOSAL UNIT (SDU).

  • Page 36 SERVICE Problem Probable Cause Corrective Action CAUTION Before installing thermostat/temperature probe, high-limit thermostat, and drain valve on replacement frypot, clean their threads and apply Loctite™ PST56765 thread sealant or equivalent to the threads. Troubleshooting and Problem Isolation This section is intended to provide technicians with a general knowledge of the broad prob- lem categories associated with this equipment, and the probable causes of each.
  • Page 37 SERVICE Problem Probable Cause Corrective Action Problems Related to the Gas and/or Electrical Current The main indicator of a gas or electrical circuit problem is an entire battery of fryers fails to light. Verify that the quick disconnect hose is properly connected, the fryer is plugged in, the main gas supply valve is open.
  • Page 38 SERVICE Problem Probable Cause Corrective Action Problems Related to the Gas Valve If the problem is not in the millivolt circuit of the pilot system, it is most likely in the gas valve itself. Follow these steps to check a Honeywell valve: 1.
  • Page 39 SERVICE Problem Probable Cause Corrective Action Follow these steps to troubleshoot a Robertshaw Valve: 1. Complete System check: With thermostat contacts closed and gas cock dial “ON”, main burner should ignite. If not, measure across TP and TH terminals. If the reading is more than 100 MV, replace the gas valve.
  • Page 40 SERVICE Flames “rolling” out of the fryer are usually an indication of negative pressure in the kitchen. Air is being sucked out of the fryer enclosure and the flames are literally following the air. If negative pressure is not the cause, check for high burner manifold gas pressure in accor- dance with the procedures in Maintenance Section.
  • Page 41 SERVICE Leakage Problems Leakage of the frypot almost always will be due to improperly sealed high-limit switches, ther- mostats/ temperature probes, and drain fittings. When installed or replaced, each of these components must be sealed with Loctite™ PST56765 sealant or equivalent to prevent leak- age.
