  • Page 9 MODELS 250 R-FS; 250 FSE These machines are solid-fuel fired meat smokers. They are intended to cook and smoke meat from the raw state to the fully cooked state. They are intended to be used in indoors- commercial settings, such as restaurants, institutions, and catering kitchens. The operation of these units is identical.

  • Page 10: Installation Instructions

    INSTALLATION INSTRUCTIONS Your unit will be shipped fully assembled. It can be handled with a 4000 pound capacity forklift. Uncrate and inspect for concealed shipping damage. Install the casters (packed inside the unit). Move unit into position. Vent according to venting instructions on the following pages. Clearances: (in cm.) From Any Combustibles: Above Top From Front...

  • Page 11: Design

    Venting Requirements Our barbecue ovens are listed under multiple standards, including U.L. 737 (Fireplace Stoves), U.L. 2162 (Commercial Wood-Fired Baking Ovens), and U.L. 391 (Solid-Fuel and Combination-Fuel Central and Supplementary Furnaces. These listing provide two alternatives for exhausting our units: direct venting and exhaust hood venting. In all cases, it is imperative to obtain the approval of the AHJ (Authority Having Jurisdiction).
  • Page 12 Option Two: Exhaust Hood Venting U.L. 2162 cites NFPA 96 (Standard for Ventilation Control and Fire Protection for Commercial Cooking Operations) as its ventilation standard. While NFPA 96 allows direct ventilation with factory-built grease ducts or properly constructed welded ducts (with fire-rated enclosures), it also permits the exhaust hood ventilation option for our units.
  • Page 13 DESIGN EMPERATURE ONTROL A thermostat activates and controls the combustion air supply to the firebox and the exhaust from the pit through the flue damper. If the unit is equipped with an electrical heating element, the thermostat also controls it. Heat and smoke flow through refractory lined flues into the cooking chamber and are circulated by a convection fan system.

  • Page 14: Operational Sequencing

    OPERATIONAL SEQUENCING Convection fan and EVAC fan are on. The primary (operator adjustable) thermostat energizes and is in control. When this thermostat requires additional temperature (sensed inside oven) to satisfy the set point, its contacts close thereby energizing the flue damper motor (item 16) and the combustion air delay timer (item 13A).

  • Page 15: Operating Procedures

    Be sure to set the temperature indicator (red arrow) at your desired cooking temperature (see 3 Cook Operation and 4 Cook and Hold Operation). b. Model 250R-FS Smoke-Master. Same procedure as 1 through 4 above, except this unit has seven racks instead of ten. Page 7 of 43...
  • Page 16 “C ” O PERATION a. Set the Selector switch in the “Cook” position and set the thermostat to the desired cooking temperature. If the unit is equipped with an electric heating element turn HTR ELEM on as desired. “C ” O OOK AND PERATION a.
  • Page 17 EMOVAL OF Racks can be pulled out to access and remove the meat. HANDLING OF RENDERED GREASE Grease that collects in the bottom of the cooking chamber should be drained by threading the grease drain extension nipple onto the drain valve fitting and draining the grease into a suitable receptacle.

  • Page 18: Troubleshooting

    EMPERATURE ROTECTION a. This pit is equipped with a safety thermostat control that will close dampers, deactivate fans, etc. if the interior oven temperature reaches 450 degrees. b. If the pit stops (lights go off, etc.) and the front door feels excessively hot to the touch, DO NOT OPEN THE PIT as there may be a grease fire inside.
  • Page 19 12. C OOKING IMES AND EMPERATURE a. The Barbecue Recipe Book gives times and temperatures for non- convection ovens. b. This unit is a Convection Oven and consequently cooks faster than ordinary ovens. c. We recommend that you cook as follows: PRODUCT TEMPERATURE TIME...
  • Page 20 PREVENTIVE MAINTENANCE – CLEANING MONTHLY: The interior fan cowling area should be cleaned. Remove the convection cowling (25), clean, and reinstall. Clean the convection fan impeller (26) at the same time. ANNUALLY: Remove the rear upper exterior skin panel. Remove the bolts that secure the hinged access cover (22) over the rear dampers and open the cover.
  • Page 21 USING YOUR “COOK & HOLD” FEATURE The Cook & Hold timer will reset the oven temperature to 145 degrees F at the end of the time set on timer. However, it will take about 2 hours for the oven to cool down from 250 degrees to 145 degrees. So, cut about 2 hours off the time you want it to cook.
  • Page 22 TROUBLESHOOTING Always de-energize the unit or the component in the unit before servicing and tag switches to warn others that service is in progress. OWER NOTHING WILL ENERGIZE Check the power supply to the unit. If no supply voltage or improper voltage, then check the breaker box.
  • Page 23 OMBUSTION OTOR OMBUSTION AMPER OTOR NOPERATIVE Check the fuse and high limit thermostat. The combustion air fan (12) and the Combustion Air Damper Motor (13) are energized when the unit is in either the “COOK”, “COOK and HOLD”, or “EVAC” modes and the appropriate thermostat is calling for a temperature increase (recall the 60 second delay for this fan after the thermostat contacts close).
  • Page 24 MOKE EAKS Check for proper EVAC fan function. Has the unit been cleaned as per the schedule in the cleaning maintenance section? Check the gaskets for proper seal (see the cleaning maintenance section for adjustment details). If gaskets are to be replaced it is important to remove all old gasket material and mastic material and clean with solvent to degrease before installing a new gasket.
