2. Start up Mode The Start up mode runs for approximately 17 minutes from the time the On button is pressed The stove will first do a Diagnostic Test of its operation and test all of the sensors The stove will also run the ash dump mechanism 3 times and move the feeder wheel to a position where there is a magnet over the feeder wheel sensor If there are any problems they will be displayed as blinking lights on the control panel These problems can be decoded from the chart in the Owner s Manual or from the chart on the Hopper door We will look at these dialogistic codes after we finish discussing all 4 running modes After the Diagnostic Test the stove will start feeding corn into the Firepot after a minute the air pump will Start up 15 seconds after the air pump starts then the stove will test both igniters After the test is done then both igniters will be engaged There should be a flame in roughly 3 minutes from the point of starting the stove If there is no flame within 10 minutes the stove will shutdown and try to restart The stove will try to restart 2 times before it flashes the 2 light did not reach operating temperature and shuts down When the stove lights normally it will run at pre set levels for the first 17 minutes At the end of Start up mode it will be on level 4 at which time it will change to what ever level the user has set The purpose of the Start up procedure is to get the stove up to operating temperature

51. ough Fuel Another thing that can cause a build up of fuel in the Burn Pot is that there is not enough fuel Unfortunately too much fuel and not enough fuel end with the same result too much fuel in the Burn Pot If there is not enough fuel the fuel in the pot will burn too quickly leaving only a small amount of burning fuel and a small flame The fuel will still be dumping in at the same rate and not all of the fuel will be lit on fire Eventually the corn that is not on fire will catch on fire The excess corn will create a larger than normal flame The excess corn will be burnt up over time since the stove is running in a lean condition This scenario of not having enough fuel will usually oscillate between a flame larger than it should be on that level and then back down to a small flame before it gets bad enough to build up in the pot This oscillation usually takes five to ten minutes per cycle So if the flame gets very large then very small this is probably a case of not enough fuel As corn is delivered to the Burn Pot the flame will drop slightly in size and rise back up again this is normal Do not confuse this with the condition of not enough fuel Too Much Fuel Not enough Fuel Exhaust Leak To distinguish between having too much fuel or not enough fuel the stove needs to be monitored prior to the build up If the Burn Pot slowly builds up with fuel then it is probably getting too much fuel in the Burn Pot The flame will al
