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 rst put into service
or if it runs out of pellets.
9. Reinstall the heat diuser/drip pan and cooking grates (See FIG 15).
10. Turn the power switch “on.” This starts the combustion air fan and illuminates the
power light. Press the “start” button on the control panel to activate the auger feed
system. (The default temperature set point is 350° F). If a higher or lower temperature
setting is desired, use the increase/decrease buttons to set the temperature. This can
be adjusted at any time after the start cycle is activated. (For cool/cold season or high
temperature cooking see the Selectable Heat Up Modes [Page 12]).
Once the start cycle is activated, three lines will appear on the display panel from lower
left to upper right indicating “heat up” mode. Once the grate temperature reaches
110° F, the actual grate temperature is displayed, alternating with the mode lines.
If the grate temperature range is exceeded during the “heat up” mode, dashing lines
will appear from upper left to lower right indicating “cool down” mode. Once the target
temperature range is attained, the lines will ash horizontal indicating “maintenance
mode”. The controller will display grate temperatures when the set point is between
150 and 495° F When the set point is between 500 and 600° F, the display will show
the set point and not the actual grate temperature.
11. Flames should be visible on the burn grate within 3 to 4 minutes. (The igniter is
active for 2 minutes. When you hit “start”, the auger turns continuously for 45 seconds
to prime the burn grate. At 46 seconds, the igniter is powered on; within 2 minutes, the
heat from the igniter and the combustion air from the fans will have a small smoldering
re started.
NOTE: The only way to reactivate the igniter is to turn the cooker o and let it go
through the cool down cycle, or simply pull the plug for a hard reset at which point you
can restart the cooker. Before restarting the Yoder, remove the grates and heat dius-
er and inspect the burn grate for any pellet overow. Remove all pellets from the burn
grate area and from the pit oor if present.
12. Once the temperature reaches the set point, open the cooking chamber and care-
fully oil the grates with vegetable oil. You are ready to cook!
Shutting Down The Smoker
When nished cooking, push the power switch to the “o” position. The controller will
begin its automatic shutdown procedure.
• The auger feed system will stop feeding fuel.
• The combustion cooling fan will continue to run until the re is burned clean.
