a) The smoker and controller location. The smoker should not be placed directly in the

sun. Direct sun light can heat the smoker to above 140 ° F in the summer time, making

controlling the temperature at 140 ° F impossible. This is especially the problem for the

Bradley Original Smoker because of its black color. The controller should be placed

away from direct sun light also. Although the controller uses a high intensity LED display,

it will still be difficult to read when sun light is directly shined to its surface. Users should

also avoid exposing the controller to water and rain, which could damage the controller.

b) Low temperature control. The control result for temperatures below 125 ° F will not be

as accurate as for higher temperatures when the smoker generator is on. This is

because there are two heaters in the smoker tower. One is the smoker heater controlled

by the PID controller. The other is the heater from the generator that is not controlled.

Our test shows that the heater in the generator itself can raise the temperature of the

smoker tower by 60 ° F (2 hours, in the shade with damper open). That means when the

ambient temperature is at 70 ° F, the smoker can be heat up to 130 ° F in 2 hours by the

heater of the generator (without using the heater in the smoker).

c) Damper position. Keeping the damper open will result in better temperature stability

because more heat loss is created. This is important when the temperature is set below

140 ° F. When the damper is closed, the temperature will take longer time to drop if it is

overshot during initial heat up. At higher temperatures, closing the damper will not affect

the performance much because the heat loss from the walls of the tower is increased.

Closing the damper at high temperature will keep the moisture of the food.

d) Temperature uniformity of the smoker tower. Our test shows that when all the shelves

were empty, the temperature inside the smoker tower was fairly uniform except the back

half of the lowest shelf that is close to the heater. Users should avoid placing the sensor

too close to the heater because it does not represent the temperature of the rest area.

When the shelves are filled, temperature variation might depend on how the foods were

placed. The bottom shelf can become hotter if more food is placed in it to block the hot

air from going up.

e) Operating the controller when ambient temperature is below 32 ° F (0 ° C). The

controller reading is only accurate for temperature ≥ 32 °F (0 °C). In addition, if the

ambient temperature is below 14 ° F (-10 ° C), the controller will not function because it

can't read the temperature correctly. In that case, users can warm the sensor by holding

it with their hands. Once the sensor is above 14 ° F (-10 ° C), it will turn on the heater.

Once the inside of the smoker is heated to above 32 ° F, the controller will run by itself.
