Summary of Contents for MONTAGUE DG Series

  • Page 1 INSTRUCTION MANUAL ONTAGUE Gas Fired Deluxe Griddles MODELS: All "DG" Series Griddles These instructions should be read thoroughly before attempting installation. Set up and installation should be performed by qualified installation personnel. Keep area around appliances free and clear from combustibles. PLEASE RETAIN THIS MANUAL FOR FUTURE REFERENCE.
  • Page 2 IMPORTANT WARNING: FOR YOUR SAFETY: Improper installation, adjustment, alteration, service or maintenance Do not store or use gasoline or can cause property damage, injury or death. Read the operating and other flammable vapors and maintenance instructions liquids in the vicinity of this or thoroughly before installing or any other appliance.

  • Page 3: Installation

    INSTALLATION Montague gas griddles are manufactured for use with the type of gas indicated on the nameplate. The Montague heavy duty gas griddles are produced with the best possible material and workmanship. PROPER INSTALLATION IS ESSENTIAL FOR SAFE AND EFFICIENT TROUBLE-FREE OPERATION.
  • Page 4 INSTALLATION THIS APPLIANCE, WHEN INSTALLED, MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES, OR IN THE ABSENCE OF LOCAL CODES, WITH THE NATIONAL ELECTRICAL CODE, ANSI/NFPA No. 70 OR THE CANADIAN ELECTRICAL CODE, CSA C22.2. VENTILATING HOOD The griddle(s) must be installed under a properly designed ventilation hood. The hood should extend at least 6"...

  • Page 5: Wiring Diagram

    WIRING DIAGRAM The wiring diagram is located on the rear of the griddle. If it cannot be found please call your local Montague Servicer or Montague Dealer. SETTING IN PLACE Using an accurate carpenter’s level, level the griddle front to back and side to side using the adjustable foot at the bottom of the legs.

  • Page 6: Gas Connection

    INSTALLATION GAS APPLIANCE REGULATOR The gas regulator supplied with the griddle must be installed on the manifold inlet at the back of the unit and adjusted for the manifold pressure specified on the equipment nameplate. Unless otherwise specified, a manifold pressure of 6.0 inches of water column for natural gas and 10.0 inches of water column for propane gas is appropriate.

  • Page 7: Pilot Adjustment

    INSTALLATION PILOT ADJUSTMENT Pilots on all griddles, except those models with suffix “-MFF”, are controlled by fixed orifices and are not adjustable. If the “-2,4OB” model option for open burners is included, then these pilots are adjustable. The front and rear pilots are controlled by one valve. To adjust the pilots, turn the adjusting screw counter-clockwise to increase or clockwise to decrease the pilot flame.

  • Page 8: Operation

    OPERATION OPERATING INFORMATION FOR THE GRIDDLE HAS BEEN PREPARED FOR USE BY QUALIFIED AND/OR PROFESSIONAL OPERATING PERSONNEL. CAUTION DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATION AIR TO THE GRIDDLE. KEEP THE APPLIANCE AREA FREE AND CLEAR FROM COMBUSTIBLES. GAS CONTROLS IN THE EVENT A GAS ODOR IS DETECTED, SHUT DOWN UNITS AT MAIN SHUT OFF VALVE AND CONTACT THE LOCAL GAS COMPANY OR GAS...
  • Page 9 OPERATION MODELS WITH SUFFIX “-SAT, SST, MST, & -TSF” These models contain standing automatic pilots with 100% pilot safety valves that automatically shut off the gas supply if the griddle pilot goes out. To light the griddle pilots, first make certain all burner manual valves or thermostat dials are rotated fully clockwise to the “OFF”...
  • Page 10 OPERATION SUFFIX “-(PR)” PILOT RE-LIGHT OPTION On griddles with the “-(PR)” Pilot Re-light Option, an electronic spark module auto- matically lights the pilot. To light the griddle pilots, follow the procedure above up until the point where you would push the piezo igniter button. Instead, simply turn the main power switch on (the “I”...

  • Page 11: Care And Cleaning

    MAINTENANCE CARE AND CLEANING CAUTION: TURN OFF GAS SUPPLY WHEN SERVICING GAS CONTROL SYSTEM. ALWAYS DISCONNECT POWER FROM GRIDDLE BEFORE REMOVING EITHER CONTROL PANEL FOR SERVICE OR CLEANING. The complete griddle should be given a periodic general cleaning. Lint and grease suspended in the air tend to collect in passages.

  • Page 12: Griddle Section

    MAINTENANCE To remove heat tint: Darkened areas sometimes appear on stainless steel surfaces where the area has been subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of the stainless steel and are not harmful. Heat tint can normally be removed by the foregoing, but tint which does not respond to this procedure calls for a vigorous scouring in the direction of the polish lines, using SCOTCH-BRITE scouring pads or a STAINLESS scouring pad in combination with a powdered cleanser.

  • Page 13: Component Access

    Removal of several equipment panels will provide easy access for performing adjust- ments and service to the Montague Deluxe Griddle. Always make certain that the gas supply shut-off valve is closed and the power cord or electrical connection is disconnected before removing access panels.

  • Page 14: Thermostat Installation

    SERVICE MODULATING THERMOSTAT (MODEL SUFFIX “-T & -TSF”) The Model BJ Robertshaw is a combination thermostat and gas valve. The gas is turned on and the temperature setting made by a single rotation of the dial. This valve automatically locks itself in the OFF position. To use, push dial inward, rotate counter- clockwise to the desired temperature.

ADJUSTMENT OF BYPASS (MINIMUM BURNER) FLAME This is the flame which must be maintained on the burners when the griddle has reached the temperature set on the dial.
  • Page 16 SERVICE THE BYPASS MUST BE SET CAREFULLY AND ACCURATELY AS FOLLOWS: Light burners and turn Dial (A) counter-clockwise and to a point midway between the "Gas On" mark and the next graduation to the right of it (shown by "X"). If the burner goes out entirely, the bypass is closed.
  • Page 17 SERVICE SNAP-ACTION THERMOSTAT (MODEL SUFFIX “-SAT”) The Robertshaw KX is a 120V snap-acting single pole thermostat. Its rugged compact design, silver contacts and heavy duty terminals are responsible for its dependable performance record. CALIBRATION CHECK: Place a reliable thermometer in the center of the top of the griddle plate over the thermal bulb.
  • Page 18 SERVICE THERMOSTAT INSTALLATION With the upper head shield and both control panels removed, slide the thermostat bulb assembly into the support brackets and the slot in the underside of the plate. Tighten the two holding screws. The excess capillary tube should be pulled forward and down as low as possible out of the heat zone, so that there is no chance of it coming in contact with the burner flame.

  • Page 19: Calibration Check

    SERVICE SOLID-STATE THERMOSTAT (MODEL SUFFIX “-SST”) The 950FT Series solid-state temperature controller features a faster reacting 100K NTC thermistor sensor and a narrow on-off differential to achieve closer control with minimal overshoot. The remote panel mount potentiometer allows for easy component placement and a cooler location for the controller module.

  • Page 20: Offset Adjustment

    SERVICE OFFSET ADJUSTMENT DO NOT USE EXCESSIVE FORCE WHEN ADJUSTING TRIM POTS, DUE TO SINGLE TURN TRIM POT ROTATION. NOTE: Units are shipped factory calibrated. Adjustment should only be made if optimum setting accuracy is desired at only one particular set point. This type of adjustment will reduce calibration accuracy at all other set points in the range.
  • Page 21 SERVICE PILOT BURNER PILOT SERVICE IN THE EVENT OF PILOT FLAME FAILURE If pilot flame burns yellow, clean pilot orifice and pilot burner to insure a steady blue flame. The orifice can be cleaned by washing in a solvent and/or blowing out with air. Flame must surround the thermocouple tip for approximately 1/2 inch.
  • Page 22 BURNER REPLACEMENT Remove the upper heat shield and control panels. Disconnect the gas line from the solenoid valve to the orifice/elbow assembly. Loosen the orifice/elbow bracket screws sufficiently so the orifice hood will come free of the burner air shutter. Remove the burner out the front of the heat shield opening.
