COOK AND HOLD MODE
The difference between this mode and “Cook” mode (“Standard or “Dual Fuel”)
is the temperature control is shifted away from the primary thermostat to a
fixed secondary (or Hold) thermostat after the operator set timer, located on the
instrument panel, counts down. To utilize this feature, simply switch the black
“COOK/OFF – COOK/HOLD” switch to the “Cook/Hold” position and set the
timer for the amount of time you wish the unit to remain in the “Cook” mode
before going into the “Hold” mode. This feature can be utilized when cooking in
either the “Standard” or “Duel Fuel” modes.
One point to remember when setting the timer, is that there is a slow “ramp-
down” from the primary (initial) thermostat set point to the secondary (Hold)
thermostat set point (non adjustable: fixed at 150º F). During this “ramp-down”
the product will continue to cook, therefore, setting the timer for the same
amount of time (cook cycle) that you would normally use will produce an over
cooked product. The timer setting should be significantly reduced to
compensate for this “ramp-down”. Some experimentation by the operator will
be necessary to fine-tune the use of the “Hold” feature.
Example: Primary thermostat set at 200º F for cooking beef brisket. You might
set the timer for 8 hours (assuming a 4 hour “Hold” period).
Please note: In the “Dual Fuel” mode the convection fan is engaged
continuously. However, when control is shifted to the secondary (Hold)
thermostat in the “Cook and Hold” mode the convection fan will cycle off each
time the fixed thermostat reaches its set point.
IMPORTANT MAINTENANCE NOTE:
In addition to the maintenance procedures described elsewhere in this manual, the electric heating
elements and the convection fan impeller should be inspected regularly, daily if possible, and
cleaned if necessary. If there is a heavy build up of soot or creosote, these surfaces should be
cleaned with a stiff brush and/or a commercial degreaser. This is especially important if the
“Dual Fuel” mode is not used each cook cycle.
