How to properly position the shelves: 1. Hold the front of both sides of the 2. Put the shelf on the slot horizontally. shelf firmly to keep it in horizontal position. 3. Lift the front about 15 degrees upward until the tag of the shelf clears the safety stop of the side rack.
COOKTOP SAFETY GUIDELINES There are dual ring burners that have the same low turn-down setting (SIM) for gentle simmering (680 BTU/hr). Use the SIM setting for melting chocolate and butter, cooking rice and delicate sauces, simmering soups and stews, and keeping cooked food hot. •...
SURFACE BURNER IGNITION Turn On Turn Off To light the top burners, push and turn the appropriate control knob counter clockwise to the "HI" position. You will hear a clicking noise - the sound of the electric spark igniting the burner. Once burner ignition has been achieved, turn the burner control knob to adjust the desired heat setting.
FLAME SIZE When you select the flame size, watch the flame when you turn the knob. Any flame larger than the bottom of the cookware is wasted. The flame should be steady and blue in color. Foreign material in the gas line may cause an orange flame during initial operation.
BURNER GRATES The grates must be properly positioned before cooking. Improper installation of the grates may result in scratching of the cooktop and/or poor combustion. OVEN BURNER USE Turn On Turn Off To light the oven burner, push and turn the appropriate control knob counter clockwise to the (150°F-500°F) position.
COOKTOP SAFETY GUIDELINES • Do not block the ducts on the rear of the range when cooking in the oven. It is important that the flow of moist warm air from the oven and fresh air into the oven burner never be interrupted. Avoid touching the vent opening or nearby surfaces during oven or broiler operation because they are hot.
OVEN FUNCTION NATURAL AIRFLOW BAKE Natural airflow bake occurs when heat is transferred into the oven from the bake burners in the bottom of the oven cavity. Heat is then circulated by natural airflow. This is a traditional bake setting. CONVECTION BAKE The oven convection fan circulates and distributes the heat in the oven for faster even cooking.
CONVECTION ROAST For best results use the broiler pan. The pan is used to catch grease spills and has a cover to prevent grease splatter. The convection fan circulates heated air over and around the food being roasted, sealing juices quickly for a moist and tender product while at the same time, creating a rich golden-brown exterior.
BROILER OPERATION CAUTION Door must be closed during broiler operation. Broiling is a method of cooking tender cuts of meat directly under the infrared broiler in the oven. Broiling in the oven is accomplished with the oven door closed. It is normal and necessary for some smoke to be present to give the food a broiled flavor.
To set the oven to Broil: 1. Place the broiler pan insert on the broiler pan. Then place the food on the broiler pan insert. 2. Arrange the interior oven rack and place the broiler pan on the rack. Be sure to center the broiler pan and position directly under the broil burner.
GRIDDLE OPERATION BEFORE USING THE GRIDDLE 1. Clean the griddle thoroughly with warm, soapy water to remove dust or any protective coating. 2. Rinse with clean water and wipe off to try with soft, clean, lint-free cloth. 3. A stainless-steel cover when the griddle is not being used is provided. Please note that the cover must be removed before turning the griddle on.
CLEANING INSTRUCTIONS DO'S • Read these cleaning instructions and the "Range Safety" section before you start cleaning your range. • Before cleaning or removing any part, make sure that everything on the range has been turned off. • Unless suggested otherwise in the following chart, allow any part to cool to safe temperature before cleaning.
CLEANING THE CONTROL PANEL, DOOR HANDLE, CONTROL HOUSING 1. Clean the control panel, door handle and control housing with a solution of mild detergent and warm water. 2. Do not use abrasive cleaners or scrubbers; they may permanently damage the finish. 3.
CLEANING OVEN DOOR GASKET Avoid cleaning this part. If you need to remove large food particles off it, proceed as follows: 1. Dampen a sponge with clean hot water. 2. Gently wipe off the soiling, but do not rub. 3. Press a dry towel gently on the gasket to dry. Do not use any cleaning detergents on the gasket.
REPLACING BURNER PARTS This diagram shows how to replace the burner parts. When replacing the burners, make sure that the two locating pins on the bottom of the brass flame spreader are properly aligned with the locating pin holes on the top of the simmer ring.
REPLACING OVEN DOOR REMOVING OVEN DOOR 3. Hold the door firmly on 1. Open the door very carefully both sides 2. Open the levers fully on 4. Close the door about halfway both sides then gently, disengage the hinges. Place on a protected surface.

DUAL BURNER CLICKING PROBLEM STEP 1 Make sure the burner design is correct. Our current design for the burner has the electrode on the left side (10 o'clock) and cross-over on the right side (2 o'clock). There are four parts for the dual burners.
STEP 3 For the flame ring base, make sure that the electrode will go through the hole on the 10 o'clock position. Make sure the electrode is not going through the hole next to the cross- over. STEP 4 Make sure the electrode is vertical to the surface of the burner base.
