Yoder YS 640 Dangers, Warnings and Cautions Failure to follow the “Dangers, Warnings and Cautions” may result in serious bodily injury, death or in a fire. • Read this manual completely before using your Yoder for the first time. • Keep the grill a minimum of 12 inches away from combustible surfaces. • The cooking chamber door must remain closed during the cool-down cycle. Failure to do so can cause burn back in the hopper. • Do not modify the holes in the burn grate.
Yoder YS 640 • When you are finished cooking, turn the power switch to the “off” position. The fan will continue to run for 18 minutes or until the temperature inside the cooking chamber falls below 125° F., whichever occurs first. During this period the cooking chamber door must remain closed. Failure to do so can cause burn back in the hopper. • Check the Yoder website (www.YoderSmokers.com) occasionally for updates and new product information for the Yoder.

Yoder YS 640 Smoker Assembly Smoker Arrival Your Yoder Smoker will arrive on a pallet wrapped and held on with metal bands. Cut the bands and remove the plastic wrap and foam from the smoker. Remove the smoker from the pallet. It is recommended that two people remove the Yoder from the pallet due to its size and weight. Open the hopper lid and remove the grease bucket that contains the power cord and a spare fuse and set aside. Open the cooking chamber and remove all the wrapped components.
Yoder YS 640 Place the cooking grates inside the cooking chamber. See FIG 3. FIG 3 Attach the front and side shelves to the Yoder. See FIG 4. FIG 4 Use the side shelf to assist in moving the Yoder into positon. It is recommended that two people move the Yoder due to its size and weight. Once in position, follow the setup instructions (Page 15) to prepare your new cooker for use.
Yoder YS 640 Leveling the Smoker The smoker must be level front to back and side to side. Use a level to help you with this. If the smoker is not level there could be problems with grease running towards the burn grate which could result in a grease fire. Operating the Smoker Initial Burn Off Before cooking on your smoker/grill for the first time, burn off the grill to rid it of any foreign matter. Follow the instructions on Page 18 for initial start-up.

Yoder YS 640 The Controller… In-Depth This is an in-depth overview of the controller’s feature set. The controller has been designed to make it as hands-off and user-friendly as possible. At its most basic level, the cooker has three modes of operation: Heat up, Maintenance and Cool Down. Beyond these basic modes are the concepts of aggressiveness, anticipation and micromanagement that have been learned as the result of many thousands of hours of testing.
Yoder YS 640 Faster Startup in Cold Weather or For High Temperature Cooking Even though the heat up mode is automatically selected, the cook can benefit from starting the pit in “H2” when the outside temperature is below 50° F., this will provide a more aggressive start over the first eight minutes. Secondly, if the target temperature is greater than 350° F. starting the pit in “H3” will get the pit to temperature much quicker. Examples Ambient temperature of 70° F. and a set point of 350° F.
Yoder YS 640 Door Open Function When the cooker has been in maintenance for more than 10 minutes and the cooker loses more than 15 degrees, the program interpretes this as the cooking chamber door has been opened. When this happens there is a specific piece of programming that is executed to help to quickly recover and get back to the set point. Prime Button The prime button overrides the program altogether and turns the auger continuously, feeding pellets as long as the button is depressed.
Yoder YS 640 Pre-Grill Checklist/Routine Maintenance Perform the following services when the grill is cool 1. Open the cooking chamber door and remove the cooking grates. FIG 8 2. Remove the heat diffuser/drip plate, remove and discard previously used protective foil cover. Install a new layer of protective foil. Select heavy duty foil that is wide enough to wrap around the edges of the diffuser plate and cut long enough to cover the entire plate.
Yoder YS 640 3. Remove the burn grate from the firebox. Inspect and clean thoroughly. Make certain that the combustion holes in the burn grate and the igniter tube in the firebox are free of debris or ash build up. Visually inspect the air way between the combustion fan and the firebox to be certain that it is free and clear of ash and debris. (A shop vacuum works well for ash and debris removal.) BURN GRATE FIREBOX FIG 10 4.
Yoder YS 640 7. Reinstall the heat diffuser/drip plate. The heat diffuser plate attaches to the hook on the auger shield and rests on the grease divider on the right hand side of the grill. Once installed check to be certain that the edges are approximately one-quarter inch below the grate rails at the hopper end and that the plate is adjusted evenly from front to back. (The diffuser is angled toward the right side of the grill to channel grease into the grease container.
Yoder YS 640 Startup Procedure (When using the Yoder with the heat diffuser/drip plate in position, it is best to start your grill 20 to 30 minutes prior to cooking. This allows the grill and cooking grates to heat completely improving heat retention and recovery when opening the cover during cooking.) 1. Confirm the power switch is in the “off” position. 2. Plug the female end of the cord in the receptacle on the back of the pellet hopper. Plug the male end into a 120 volt 15-amp GFI-protected outlet.
Yoder YS 640 6. Adjust the variable displacement damper to wide open (fully on the right side) prior to starting the grill. VARIABLE DISPLACEMENT DAMPER FIG 15 7. Check to see that the burn grate is properly seated in the firebox.
Yoder YS 640 8. Place 1/8 cup (about a palm full) of pellets on the burn grate. NOTE: This step is only necessary when the unit is first put into service or if it runs out of pellets. 9. Reinstall the heat diffuser/drip pan and cooking grates (See FIG 14). 10. Turn the power switch “on.” This starts the combustion air fan and illuminates the power light. Press the “start” pad on the control panel to activate the auger feed system. (The default temperature set point is 350°F).
Yoder YS 640 • The fan will continue to run until the grill temperature reaches 125°F or 18 minutes, whichever occurs first. • When the procedure is complete the fan and power LED will turn off. • Disconnect the Yoder from its power source. When the grill is completely cool, cover the grill to protect your investment and keep the pellets dry.
Yoder YS 640 Manual Start Up Here are the steps to manually light the grill in the event that the igniter fails. (Steps 2 & 3 only apply if the igniter has developed a dead short and is tripping the GFI or blowing the fuse.) 1. Remove the cooking grates, diffuser plate and the burn grate.
Yoder YS 640 2. Reach into the hopper cavity on the left side of the igniter tube and pull the igniter wires into the firebox. 3. Unplug the igniter’s weather tight connection and then push the wires back into the hopper cavity. TO IGNITER IN COOKING CHAMBER TO CONTROL BOX FIG 20 4. Reinstall the burn grate and place a small handful of pellets onto the grate. 5. Light the pellets with a torch, starter gel or starter stick. 6.
Yoder YS 640 Getting the Most From Your Yoder: Direct & Indirect Grilling, Smoking & Baking Heat Up Times and Grate Temperatures The question is regularly asked: “How long does it take from the time I press “start” until I am ready to cook?” When the cooker is setup traditionally (diffuser plate installed) the heat up time is 20 to 30 minutes. When the cooker is setup for direct and indirect grilling (diffuser plate out) the heat up time is about 15 minutes.
Yoder YS 640 VARIABLE DISPLACEMENT DAMPER FIG 21 Setup #2: Moderate temperature grilling such as wings and boneless chicken breasts (grate temperatures up to 350°F): Heat with the diffuser plate in place and a set of Grill Grates installed on the left side of the cooker. The “Direct Grilling Kit” consists of three custom-made aluminum panels and replaces one standard cooking grate (see FIG 22). Option: Two sets of grill grates for extended direct grilling surface.
Yoder YS 640 Setup #3: Direct grilling with searing capability: Remove the heat diffuser plate, set the variable displacement damper in the full open position (FIG 26) and install the Grill Grates on the left side of the cooker. (With the heat diffuser/ drip plate removed, some users prefer to line the bottom of the cooker with foil to facilitate cleanup).

See FIG 25. EXAMPLE: DIVIDED AREAS (Top View) HANDLE DAMPER POSITION FIREBOX HEAT ZONE @300 DEG. F • HEAT ZONE @240 DEG.
Yoder YS 640 Grill Maintenance Preparing the Grill for the Season Begin with a thorough inspection of the entire grill correcting any issues you find. Follow the steps found in the Pre-Grill checklist (Page 15). Painted Surfaces Yoder smokers are painted with high heat silicone paint. When cleaning the smoker, surfaces should be washed down with warm soapy water using a neutral detergent and rinsed with clean water.
Yoder YS 640 Firebox and Burn Grate Assembly Maintenance It is recommended that the firebox assembly is regularly inspected to be certain that it remains free of ash and debris which will insure proper performance. The firebox is a fully welded structure that carries the burn grate and channels the combustion air. The firebox is bolted to the cooking chamber floor and the seams on the hopper wall and the floor of the cooking chamber are sealed with a high temperature silicone.
Yoder YS 640 If the gap is greater than 3/16” the below steps should be followed. 1. Start by removing the burn grate from the firebox and placing it on its top. 2. Next, step on the burn grate and apply enough pressure to bend it back to its original shape. DO NOT apply too much pressure or you will overcorrect the burn grate and it will not fit back into the firebox. FIG 28 3. Place the burn grate back into the firebox and check the gap between the back wall and the burn grate to insure a proper fit.
Yoder YS 640 Igniter When inspecting the firebox assembly, confirm that the igniter assembly, tube and igniter rod are free of ash or other debris. Periodically check the four set screws that secure the igniter rod into the tube. (See FIG 30). Verify that the igniter rod is centered in the tube and that the tip of the igniter rod is extended approximately 1/8” out from the igniter tube. Extending 1/8” out of igniter tube.
Yoder YS 640 FIG 31 Grease Management Area and Bucket Always be sure the grease catch area is clean and free of debris and empty the grease bucket regularly. Additional Maintenance: In addition to regular cleaning, perform the following procedures every 30 days: 1. Use a stiff brush to remove any build-up on the inside walls of your grill. Inspect and clean the inside of the lid, the heat diffuser/ drip tray and the inside walls of the cooking chamber. 2.
Yoder YS 640 FIG 32 Storing Your Grill Cover your Yoder Smoker to protect it from the weather and to keep the pellets dry. If storing your cooker inside, be sure the smoker is cool to the touch before moving it inside. Inspect the hopper and cooking chamber for any remaining embers before storing the unit.
