IMPORTANT SAFEGUARDS
2
Gas must be installed by a qualified service technician in accordance with all applica-
ble codes and requirements of the authority having jurisdiction. Before proceeding
with any conversion, ensure the gas supply is shut off and the electrical power to the
range is disconnected. Do not operate the cooktop or oven burners of this range when
using LP (bottled) gas before converting the pressure regulator and burner orifices for
LP gas use. Failure to do so could cause high flames and toxic fumes which can
result in serious injury.
●Do not use an adapter or extension cord to connect this appliance to electricity.
Extension cords do not guarantee the required safety of the appliance.
●To guarantee the electrical safety of this appliance, continuity must exist between
the appliance and an effective grounding system. It is imperative that this basic
safety requirement be met. If there is any doubt, have the electrical system of the
residence checked by a qualified electrician.
●Do not operate the appliance until it has been properly installed and grounded by a
qualified technician.
●Have the technician show you the location of the gas shut off valve and how to shut
it off in case of an emergency situation.
●Before servicing, turn off the gas valve and disconnect the power supply by either
removing the fuse, unplugging the unit, or manually "tripping" the circuit breaker.
●Under no circumstance open the outer casing of the appliance. This is a safety
hazard and may damage the appliance.
●Service or repairs should only be carried out by a qualified service technician. Do
not attempt to repair the appliance yourself.
●For safety, only use parts / components recommended by the manufacturer.
●The appliance is not designed for use with an external timer or a remote-control
system.
●Do not operate the appliance if the power cord or plug is damaged, or if the appli-
ance has been damaged in any manner.
●In the event of damage or defect, turn off the appliance immediately. Turn off the
gas shut off valve and disconnect completely from the electrical supply. Do not use
the appliance until it has been repaired. Ensure power is not supplied to the appliance
while repair work is carried out.
●IMPORTANT: Gas appliances can cause minor exposure to four of these substanc-
es, namely benzene, carbon monoxide, formaldehyde, and soot, caused primarily by
the incomplete combustion of natural gas fuel. When operating your range on natural
gas, the flames from the burners should be blue in color. In addition, the flames
should be stable, free of yellow tipping, excessive noise and lifting. However, this
yellow tipping should be restricted to the primary flame kernels only. Properly adjust-
ed burners, indicated by a bluish rather than a yellow flame, will minimize incomplete
combustion. Exposure to those substances can be minimized by venting with an
open window or use of a ventilation fan or hood.
●Before discarding an old appliance, disconnect it from the gas and electrical supply,
and cut off the power cord to prevent it from becoming a hazard.
●To reduce the risk of burns, do not move this appliance while hot.
CHILDREN
●Children should not be left alone or unattended in an area where the appliance is in
use.
●Never allow children to sit or stand on any part of the appliance.
●CAUTION: Do not store items of interest to children above or at the back of the
appliance. Children climbing on the appliance to reach these items could be injured.
●The appliance is hot during use and remains so for some time after being switched
off. Keep children away from the appliance.
●Keep all cookware and their handles out of the reach of children. Danger of burning
or scalding.
WARNING: Ensure that any packing material, including any plastic bags or film, are
disposed of safely and kept out of the reach of children. Do not use plastic bags in
cribs, beds, carriages or play pens. These bags are not toys. Danger of suffocation!
TECHNICAL SAFETY
●Installation, repair, and maintenance work must be performed by a licensed install-
er, an approved service agency or your gas supplier in accordance with local building
and safety codes. Work by unqualified persons could be dangerous and may void the
warranty.
●Before installation, make sure that the voltage and frequency listed on the rating
label correspond with the household electrical supply. This data must correspond to
prevent injury and appliance damage. Consult a qualified electrician if in doubt.
●Before installation, select a suitable area that abides by the clearance measure-
ments noted in the ‘RANGE INSTALLATION’ section of this manual.
●Before installation, ensure the area will be well ventilated, with a suitable ventilation
system.
IMPORTANT: Do not install a ventilation system that blows air downward toward this
gas cooking appliance. This type of ventilation system may cause ignition and com-
bustion problems with this gas cooking appliance resulting in personal injury or unin-
tended operation.
●Before installing the range, check for externally visible damage. Do not operate a
damaged appliance. A damaged gas range is a hazard.
●This appliance is equipped with a three-prong (grounding) plug for your protection
against shock hazard and should be plugged directly into a properly grounded
three-pronged receptacle. DO NOT cut or remove the grounding prong from this plug.
●The range has been adjusted for Natural Gas at manufacture. Any conversion to LP

experience with the appliance should not use it without supervision or instruction by
a responsible person.
●Do not use this range while under the influence of alcohol or other substances that
affect your reaction time or perception.
WARNING: TIP-OVER HAZARD
TO REDUCE THE RISK OF THE APPLIANCE TIPPING OVER, THE RANGE MUST BE
SECURED BY THE ANTI-TIP DEVICE PACKED WITH THE APPLIANCE. IF THE
ANTI-TIP BRACKET IS NOT PROPERLY INSTALLED, THE RANGE MAY TIP, CAUSING
DAMAGE TO THE APPLIANCE AND SERIOUS BURNS OR INJURY TO PERSONS OR
POSSIBLE DEATH. See 'RANGE INSTALLATION' for further instructions.
COOKING SAFETY
● Make sure all components of the range are assembled correctly before using the
cooktop or oven.
● Do not leave the range unattended while in use. Boil-overs cause smoking, and
greasy spillovers may ignite.
● The range and its parts will be extremely hot during use. Always use protective
gear such as oven mitts or potholders when using the appliance. Do not touch the
open flame.
● Use only dry, heat resistant potholders. Moist or damp potholders used on hot
surfaces can result in steam burns. Do not let the potholder touch the hot heating
elements. Do not use towels or other bulky items near the appliance.
● The appliance is hot during use. Do not touch the Burner Grates, Burner Caps,
Burner Heads, Griddle, Oven Racks, oven glass, or any other parts in proximity to the
flame or oven heating elements. These components may be hot enough to cause
burns.
● Be sure to turn all controls off when not in use. The appliance will remain hot for
some time after turning off. Do not touch the cooktop area or interior of the ovens
until cool.
● Be sure the oven cool air intake (at top of oven door) and oven exhaust vent (below
the door) are unobstructed at all times.

6
● When using the oven, open the door carefully to allow hot air or steam to escape
before placing or removing food.
● The Burner Grates supplied with the appliance must always be used, unless
replacing with the Griddle. Never place cookware on the burner by itself.
● Do not operate a Burner for an extended period of time without cookware on the
Burner Grates. The finish of the grates might chip without cookware to absorb the
heat.
● Ensure the cookware you are using is suitable for a gas cooktop or oven. Only
certain types of glass, ceramic or other glazed cookware are suitable for use on a
cooktop without breaking due to the sudden temperature change.
● Cookware that conducts heat slowly, i.e., glass pots, should be used in conjunction
with burner flames at a low or medium setting.
● Do not use cookware with a base that extends past the Burner Grate. Using larger
cookware may cause the flames to spread out and damage the surrounding coun-
tertop or other countertop appliances.
● For safety and stability, do not use cookware with a bottom diameter smaller than
the burner grate opening.
● Do not use cookware so large that it covers several burners. The resulting heat
accumulation can damage the appliance.
● Select a heat source size that is as close as possible to the bottom diameter of the
cookware. Also, keep gas flames confined to the base only and not the sidewalls of
the cookware.
● Do not heat empty pots or pans. This may cause damage to the cookware and the
surrounding area. Danger of fire.
● Always turn pot handles to the side or back of the range. Do not turn handles
towards the area where they can be easily burned. Handles should not extend over
the adjacent burners.
● Do not heat unopened food containers, such as baby food jars or cans. Built-up
pressure may cause the container to explode and result in injury.
● Do not use plastic or aluminum foil to line any part of the range. It melts at high

absence of local codes, in accordance with the National Electrical Code (ANSI/NFPA
70, latest edition). A copy of this standard may be obtained from the National Fire
Protection Association.
● The power supply must be the correct polarity. Reverse polarity will result in contin-
uous sparking of the electrodes, even after flame ignition. If there is any doubt as to
whether the power supply has the correct polarity or grounding, have it checked by a
qualified electrician.
● Use 120V, 60Hz, properly grounded branch circuit protected by a 15-amp or
20-amp circuit breaker or time delay fuse.
● A separate circuit, servicing only this appliance is required.
● Place the power outlet so that it is accessible after the appliance has been installed.
WARNING: Disconnect the appliance from the main power supply before installation
or service.
GROUNDING
● The power cord is equipped with a three-prong (grounding) plug which mates with
a standard three-prong grounding wall receptacle to minimize the possibility of elec-
trical shock hazard from the range.
WARNING: DO NOT cut or remove the grounding prong from the power cord.

GAS SUPPLY REQUIREMENTS
● Installation and service must be performed by a qualified installer.
● The range has been equipped and adjusted for use with natural gas (NG) at manu-
facture.
● For use with liquid propane (LP) gas, the range must be properly adjusted by a qual-
ified installer. The appliance has been supplied with a liquid propane (LP) Conversion
Kit. Each orifice has been clearly identified on the orifice packaging to identify with
which burner it corresponds with. Refer to the ‘PARTS’ section of this manual for a
table listing orifice sizing.
● Ensure the gas appliance pressure regulator has been set for the gas which the
appliance will use. The gas appliance pressure regulator is located at the bottom
right, rear of the range.
● Installation of this range must conform with local codes, or in the absence of local
codes, the National Fuel Gas Code, ANSI Z223.1 / NFPA 54. This range has been
design-certified according to ANSI Z21.1b-2012 latest edition.

CONNECT RANGE TO GAS SUPPLY
● When all connections have been made, check
that all range controls are in the ‘OFF’ position
and open the main gas supply valve.
● Leak testing of the appliance shall be conduct-
ed according to the manufacturer’s instructions.
Use some soapy water (50% water and 50%
liquid detergent) or a leak detector at all joints
and connections to check for leaks in the
system. Open the valve and check for leaks by
placing the liquid solution onto all gas connec-
tions. Bubbles around connections indicate a
gas leak. If a leak appears, close the shut-off
valve, and adjust connections. Do not use a
flame to check for gas leaks.
● The appliance must be isolated from the build-
ing’s gas supply piping system by closing its
individual manual shut-off valve during any
pressure testing of the gas supply piping system
at test pressure equal to or less than ½ psi
(3.5kPa).
Gas shut-off valve
● The range must be connected to a regulated gas supply. The supply line must be
equipped with an approved external gas shut-off valve located near the range in an
accessible location. Do not block access to the shut-off valve.
● All connections to the gas piping must be wrench-tightened. Do not overtighten or
allow pipes to turn when tightening.
● Any pipe connections must be made using a thread sealant approved for gas
connections. Failure to correctly install these items could lead to a gas leak and
subsequent explosion.
● Install male ½” flare union adapter to ½” NPT internal thread elbow at inlet of regu-
lator. On models equipped with standard double burners, install the male pipe thread
end of the ½” flare union adapter to the ½” NPT internal thread at inlet of pressure
regulator. Use a wrench on the regulator fitting to avoid damage.
● Install male ½” or ¾” flare union adapter to the NPT internal thread of the manual
shut-off valve, taking care to secure the shut-off valve to keep it from turning.
● The gas supply pressure for checking the regulator setting is 7” (Natural Gas) and
11” (LP gas). Connect flexible gas line connector to the regulator on the range. Posi-
tion range to permit connection at the shut-off valve.
