Operations 

 

Turn the oven ON and set the cooking temperature. Two additional controls are used to control the fan (as described below). 

The timer is a reminder of cooking process done. The timer does not control the temperature of the oven. 

To cook, do the following: 

Turn the oven main power switch ON. 

Choose the fan speed using the Fan Speed switch. The appropriate fan speed (HI or LOW) depends on the type of food to be 

cooked. 

Switch the Fan Mode switch to COOK. The fan will run continuously when the oven doors are closed (the fan works 

independently of the gas system). (If this switch is turned to COOL, the only difference is that the fan will continue to rotate 

when the oven doors are open.) 

Set the cooking temperature by turning the Cook Temperature Control until the indicator mark on the knob is pointed to desired 

cooking temperature. The HEAT ON indicator will be on when the burners are on and will remain on while the oven is heated. 

Wait until the HEAT ON indicator cycles on and off for three times, the pre-set temperature has been reached. Open the oven 

doors, load the product into the oven, and close the doors. 

You can use the Cook Timer as a reminder of cooking process. If yes, turn the Cook Timer knob until the indicator mark points to 

the desired cooking time (up to 55 minutes). The timer knob will rotate counterclockwise as the timer runs down, indicating how 

much time remains. You can turn the knob while cooking to increase or decrease the remaining time. When the timer runs out, 

a buzzer will sound for a short time, then turn itself off. (To immediately silence the buzzer, turn the Cook Timer knob to the OFF 

position.) The timer is a reminder to you; the timer does not control the oven. 

If you open the oven doors, the burners and fan will shut off until the doors are closed. However, the timer will continue running 

even if the doors are open. 

For ovens that are equipped with an oven interior light, to turn on the light, press and hold the switch located at the bottom of 

the control panel. 

When the load has finish cooking, you can rapidly cool the load by opening the oven doors (which will shut off the burners) and 

switching the Fan Mode to COOL (which will cause the fan to run even though the doors are open). For the most rapid cooling, 

also switch the Fan Speed switch to HI. 

After cooking is done, turn the Cook Temperature Control to the lowest setting (fully counterclockwise) and switch the Power 

Switch to OFF. 

 

CLEANING - NOTE: To maintain cleanliness and increase service life, this item should be cleaned daily. Do not water jet to spray 

water directly on the unit, if liquid enters the electrical compartment it may cause a short circuit or electrical shock. 

Before cleaning or attempting to move this item always turn off, unplug and let the unit to cool down completely. 

Wipe the entire unit with a clean soft cloth until it is completely dry. 

To avoid damage to the unit, do not use abrasive cleaners or scouring pads. 

If soap or chemical cleaners are used, be sure they are completely rinsed away with clean water immediately after cleaning. 

Chemical residue could damage or corrode the surfaces of the unit. 

To avoid serious injury or damage, never attempt to repair or replace a damaged power cord yourself. Contact a professional 

technician for repair service. 

 

MAINTENANCE: 

 A qualified service company should check the unit for safe and efficient operation on an annual basis. 

 Gas piping shall be a certain size and installed to provide a supply of gas sufficient to meet the full gas input of the equipment. 

 A manual shut off valve should be installed upstream from the manifold within 4 ft. (1.2m) of the equipment and in a position 

where it can be reached in the event of an emergency. 

 Check entire gas piping system for leaks every so often. Using a gas leak detector or soapy water solution is recommended. 

 Install equipment under efficient exhaust hood with flameproof filters with a distance of no less than 4 feet between the top 

of the equipment and the filters or any other combustible materials.
