What are the two Pre-Sets for the I-Roast2?

                stage 1             stage 2               stage 3
Preset1:  450 F for 10:00            NA                  NA
Preset2:  455 F for 6:00    400 F for 4:00    435 F for 1:30

How do I record and retrieve my own curves on the I-Roast-2 ?

• Recording: In order to save a roasting profile, press the COOL/TIME button. The display will show "REC". To choose the memory setting of 1-10, press the UP or DOWN arrow buttons.

  For example: you want program #7, use the UP or DOWN buttons until you see #7. then press the COOL/TIME button again. The display will show "END" for three seconds. this will complete the process and set the roaster to "0."

• Retrieving: To retrieve a saved roast profile, push the COOL/TIME button. The display will show "REC." Push the UP or DOWN arrows to locate the number of the curve you have already entered into memory. Press ROAST/TEMP to begin roasting.

• A) Setting temperature:
  This is the target temperature for each roasting stage. Due to possible power limitations and ambient temperatures, it may take several minutes to reach this target temperature. After the setting temperature is reached, I-Roast will maintain this temperature for the rest of time in this stage. In certain extreme cases, it is just impossible to achieve the goal you set, for example, if you set stage 1 for 485¡F for 10 seconds, then you won't be able to get 485¡F in 10 seconds, it's just impossible.

• B) LCD Display temperature:
  this is the temperature as read by the temperature sensor located upstream of the glass roasting pot. If you look down at the top opening of the power base, you will see this little red sensor.

• C) Real bean temperature:
  if you could measure temperature inside the roasting pot, you would measure the air temperature around the beans at the point of measuring. You may get different temperature at different measuring spots, and at different roasting stages you would see the temperature fluctuate. The actual bean temperature is very hard to measure if not impossible.

How does the I-Roast work?

• In the first stage, the I-Roast will have low motor RPM (low air flow) most of the time together with the highest heating power in order to reach the setting temperature as quickly as possible. And because the beans are green and cold in the beginning, they can resist the heat better than later stage.
• After the setting temperature is reached, the I-Roast will kick into high RPM mode and maintain this temperature for the rest of the time remaining in that stage. If you have chosen a relatively high temperature setting, you may find that it takes longer for the roaster to kick into the high RPM range -- This may cause an un-even roast and sometimes burns on the beans. This may be the case if the ambient temperature is cold, it takes a longer time to reach your setting temperature.

What if the bean aren't mixing well enough? if they scorch early on.

• Clean up the chaff collector screen!!! And make sure the input voltage is high enough. The unit is rated at 120V.
• Please refer to "How does the I-Roast work?"
• Most likely, you have a relatively high temperature setting, and it is taking longer for the roaster to kick into high RPM range -- This may cause an un-even roast and sometimes burns on the beans.
• Try to set the temperature lower, for example, set the highest temperature at 440¡F.
• Also you can try reducing the roast amount. Measure carefully. Overfilling will prevent the beans from moving around well in the first stage.

• Most people find the roasting results from Preset1 and Preset2 to be on the darker side. Many people will want to reduce the time or decrease the temperature of the presets to get the desired roasting result.
• However, if you feel your roast is not roast dark enough using the presets, please first check the input power, it is rated at 120V with 1500W.
• It may be due to cold environment. It will always take a longer time to get dark roast if the ambient temperature is low.
• You may have too much hot air leakage -- please make sure all parts are locked in position and  not loose. If too much hot air is leaking from the lid, the gaps or the holes, then you will lose too much heat.

Hearthware has included a dandy thingy (not shown) that fits on top of the chaff collector. It looks sort of like a chrome crown, but in fact a standard 4 inch dryer vent hose fits snugly on top, and can be conveniently tossed out the nearest window while roasting to vent the smoke outside. Be aware that it also changes the roast profile significantly. Your roasts will progress more quickly than when you're roasting vent-less, so keep an eye on it and be ready to hit the manual cool button when you have reached the desired roast level.

• There are four bigger holes on the top lid, (not opened).
• Insert the 4 short straight prongs on the smoke vent attachement into these 4 holes. Then you have the whole assembly looks like this picture: http://www.hearthware.com/images/i-Roast-a.jpg
• Then you can attach an flexible aluminum pipe on the top. You can bend the top 4 prongs to make the pipe fit tight.
• >DO NOT touch any part of the unit, any part of the vent or the pipe during roasting, they will be very hot (~450¡F) and may cause burns!
