Electrical Connection

120volt, 60 Hertz, properly grounded dedicated circuit protected by a 10A circuit breaker or time-delay fuse.
NOTE: Use of automatic, wireless, or wired external switches that shut off power to the appliance are not recommended for this product.

Extension Cord Cautions

Because of potential safety hazards associated with certain conditions, we strongly recommend against the use of an extension cord. However, if you still elect to use on extension cord, it is absolutely necessary that it be a UL- listed, 3-wire grounding-type appliance extension cord and that the current carrying rotting of the cord in amperes be equivalent to, or greater than, the branch circuit rating.

Grounding – Importance

For personal safety, this appliance must be properly grounded. The power cord of this appliance is equipped with a three-prong(grounding) plug which mates with a standard three-prong grounding wall receptacle to minimize the possibility of electric shock hazard from this appliance.

Where a standard two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to have it replaced with a properly grounded three-prong wall receptacle.
Do not, under any circumstances, cut or remove the third(ground) prong from this power cord.

Install Burner Heads

• Being sure that the tabs on burner head are aligned and inserted into notch of burner base on
  cooktop. Assemble center burner, when used, as shown in Fig. 6
  

Install Grate

• Grate is located by positioning locating fingers on burner base holder.

Control Test

• Check to see that all controls are in the off position.
• Turn controls on to check unit operation.
• Turn controls off after checking operation.

How To Use The Cooktop Gas Burners

Gas flow to the burners is adjusted by turning the knobs which control the valves. Turning the knob so that the indicator line points to the symbols printed on the panel achieves the following functions:

• When knob is rotated to the maximum position it will permit the rapid boiling of liquids, whereas the minimum position allows the simmer warming of food or maintaining boiling conditions of liquids.
  

• To reduce the gas flow to minimum, rotate the knob further counter-clock- wise to point the o Lo Position.
  

• Other intermediate operating adjustments can be achieved by positioning the indicator between the HI and Lo positions, and never between the HI and OFF position.
  

• When the range is not being used, set the gas knobs to their OFF positions and also close the gas shut-off valve placed on the main gas supply line.

Burner Ignition

• Any film or stickers on the cooktop surface should be removed before use.
• All operations are performed by means of all control knobs. Knob controls electric ignition, safety device & flame level.
• To ignite, push and turn the knob for 1~2 seconds in a counterclockwise direction up to the HI position(Maximum rate), push in and hold the knob until the flame has been lit. The sparks produced by internal igniter will light the designated burner.
  

During a power failure, the burners will not light automatically. In an emergency, a cooktop burner may be lit with a match by following the steps below:

WARNING

Lighting gas burners with a match is dangerous. You should match light the cooktop burners only in an emergency. On models so equipped, check to be sure the cooktop is in the unlocked position.

1. Light a match and hold the flame near the burner you want to light. Wooden matches work best.
2. Push in and turn the control knob slowly. Be sure you are turning the correct knob for the burner you are lighting.
   NOTE: If the burner does not light within five seconds, turn the knob off and wait one minute before trying again.
   • The burner flames Turn each burner on. Flames should be in color blue with no trace of yellow. The burner flames should not flutter or blow away from the burner. The flame should be no less than 1/4″ on the lowest setting and no greater than 1-1/2″ on highest setting.

WARNING

If you attempt to measure the flame, please use caution. Burns could result.

• In the event that the local gas supply conditions mark it difficult to light the burner in the HI position, try again with the knob in Lo position.
• To re-light the burner, return the knob to the OFF position and repeat the operation for light.
• To shut off burner, turn the knob in clockwise direction, to OFF position.
  

Chose Of The Burners And Pans

For greater efficiency and lesser gas consumption, use the pots and pans with the right diameters of the burners. Avoid having flames extending out from underneath the pans(refer to the table). A smaller diameter pot or pan placed on a larger burner does not necessarily mean that the boiling conditions are reach quicker.

Table of recommended pans

Burner| Pan diameter inch
Auxiliary| From dia. 3.2 to dia. 5.5
Semi rapid| From dia. 5.5 to dia. 7.9
Rapid| From dia. 20 to dia. 28
Triple ring| Above dia. 26

How to Select the flame size

For safe handling of cookware, never let the flames extend beyond the edgeof the cookware.
Watch the flame, not the knob, as you reduce heat. The flame size on a gas burner should match the cookware you are using.
Any flame larger than the bottom of the cookware is wasted and only serves to heat the handle.
