Install the continuous front-rail, if ordered. 9. Slide control knobs onto their shafts (to operate the sections during the installation procedure), but do not yet reattach valve panels or front-panel trim pieces. STEP 5: CONNECT ELECTRICITY (OVEN BASE) A wiring diagram is located behind on the rear of the oven.
INFRARED BROILER INSTALLATION Minimum supply pressure is 7” W.C. for natural gas, 11” W.C. for propane. An external pressure regulator and shut off valve are provided. If using a flexible-hose gas connection, the I.D. of the hose must not be smaller than the connector on the equipment, and must comply with ANSI Z21.69. Provide an adequate means of restraint to prevent undue strain on the gas connection.
OPERATION INFRARED BROILER OPERATION DANGER EXPLOSION HAZARD In the event a gas odor is detected, shut down equipment at the main gas shut-off valve and immediately call the emergency phone number of your gas supplier. Improper ventilation can result in headaches, drowsiness, nausea, and could result in death. Do not obstruct the flow of combustion and ventilation air to and from cooking appliances.
INFRARED BROILER OPERATION 3. Turn the burner control(s) to HIGH and visually check that the burners have ignited. When the burners ignite, a blue flame will cover the surface of the ceramics for 10-15 seconds. Within 30 seconds this haze will disappear and the ceramics will glow red. The flame on the surface of the ceramics should be barely visible, with practically no blue haze. 4.

INFRARED BROILER OPERATION Figure 11 Operation of Oven Each oven has a thermostatic control that can be set in the oven 175°F to 550°F (66°C to 260°C). Convection ovens have a fan that can be set to HI speed or LO speed. For advice on using a convection oven, see the information on the following two pages of this manual. While cooking, if the door is opened on a convection oven, the fan and heat will temporarily stop until the door is closed.
OPERATION INFRARED BROILER SUGGESTIONS FOR COOKING USING A CONVECTION OVEN As a guide, set oven temperatures 25 to 50 degrees lower than called for in recipes using conventional (non-convection) ovens. FROZEN ENTREE PRODUCTS: Punch holes in lid before heating. Tent lid if product has a tendency to stick, i.e., lasagna or macaroni and cheese. Use manufacturer’s convection oven directions for time and temperature or reduce conventional oven temperature 50 degrees for a 6-1/2 size pan load.
INFRARED BROILER OPERATION CORRECTING PROBLEMS WHEN COOKING WITH A CONVENTION OVEN If... Then... Cakes are dark on the sides and not done in the center… lower oven temperature Cake edges are too brown… reduce number of pans or lower oven temperature Cakes have light outer color… raise temperature Cake settles slightly in the center… bake longer or raise oven temperature slightly. Do not open doors too often for long periods. Pies have uneven color… reduce number of pies per rack.
COOKING HINTS INFRARED BROILER COOKING HINTS Due to the speed of the Infra-red broiler, broiling times will be reduced and cooking techniques may need some modification. For most broiling of steaks, chops, etc., the burners should be operated on “HI” and the degree of internal rareness and surface condition can be controlled by raising or lowering the rack mechanism.
INFRARED BROILER COOKING HINTS TROUBLESHOOTING BY OPERATOR The following table lists the possible causes and solutions of problems that may occur during operation. Problem Possible Causes and Solutions A top burner will not light. – Check pilot position. – Check and light the burner’s pilot. – Check gas supply to unit. Oven will not heat up. – Check and light the oven pilot. – Check gas supply to unit. Blower of convection oven is not running.
CLEANING INFRARED BROILER CLEANING WARNING Disconnect the power supply to the appliance before cleaning. Do not remove panels that require tools to remove. WARNING Adjustments and service work should be performed only by a qualified technician who is experienced in, and knowledgeable with the operation of commercial gas cooking equipment. To assure confidence, contact your authorized service agency for reliable service, advice and other assistance with your appliance.
INFRARED BROILER CLEANING Rubbing cleanser, as gently as possible, in the direction of the polished lines will not mar the finish of the stainless steel. NEVER RUB WITH A CIRCULAR MOTION. Soil and burnt deposits which do not respond to the above procedure can usually be removed by rubbing the surface with SCOTCH-BRITE scouring pads or STAINLESS scouring pads. DO NOT USE ORDINARY STEEL WOOL as any particles left on the surface will rust and further spoil the appearance of the finish.
