Safety Practices for Servicer
Safe and satisfactory operation of gas ranges depends
upon its design and proper installation. However, there is
one more area of safety to be considered:
Servicing
Listed below are some general precautions and safety
practices which should be followed in order to protect
the service technician and consumer during service and
after service has been completed.
1. Gas smell—Extinguish any and all open flames and
open windows.
2. Turn gas off—Service range with gas turned off
unless testing requires gas.
Important Safety Information
3. Checking for gas leaks—Never check for leaks with
any kind of open flame. Soap and water solution
should be used for this purpose. Apply solution to
suspected area and watch for air bubbles which
indicates a leak. Correct leaks by tightening fittings,
screws, connections, applying approved compound,
or installing new parts.
4. Using lights—Use a hand flashlight when servicing
ranges or checking for gas leaks. Electric switches
should not be operated where leaks are suspected.
This will avoid creating arcing or sparks which could
ignite the gas. If electric lights are already turned on,
they should not be turned off.
5. Do not smoke—Never smoke while servicing gas
ranges, especially when working on piping that
contains or has contained gas.
6. Check range when service is completed—After
servicing, make visual checks on electrical
connections, and check for gas leaks. Inform
consumer of the condition of range before leaving.
7. Adhere to all local regulations and codes when
performing service.
Receiving Oven
• Installer needs to show consumer location of the range
gas shut-off valve and how to shut it off.
• Authorized servicer must install the range or cooktop
in accordance with the Installation Instructions.
Adjustments and service should be performed only by
authorized servicer.
• Insure all packing materials are removed from the oven
before operating it, to prevent fire or smoke damage
should the packing material ignite.
• Ensure range or cooktop is correctly adjusted by a
qualified service technician or installer for the type of
gas (Natural or LP). Some ranges can be converted
for use with Natural or LP gas.
• With prolonged use of a range, high floor
temperatures could result. Many floor coverings will not
be able to withstand this kind of use. Never install
range over vinyl tile or linoleum that cannot withstand
high temperatures. Never install range directly over
carpeting.
Using the Oven
• Do not leave children alone or unattended where an
oven is hot or in operation. They could be seriously
burned.
• Do not allow anyone to climb, stand or hang on the
oven door. They could damage the oven and cause
severe personal injury.
• Wear proper apparel. Loose fitting or hanging
garments should never be worn when using the oven.
Flammable material could ignite if brought in contact
with hot oven surfaces which may cause severe burns.
• Never use the oven for warming or heating a room.
This may cause burns, injuries, or a fire.
• Do not use water on grease fires.
• Do not let grease or other flammable materials collect
in or around the oven.
• Do not repair or replace any part of the oven unless it
is recommended in this manual.
• Use only dry potholders. Moist or damp potholders
used on hot surfaces may result in a burn from steam.
• Do not let a potholder touch the flame. Do not use a
towel or a bulky cloth as a potholder.
• Never leave the oven unattended while cooking.
• Only certain types of glass/ceramic, earthenware, or
other glazed utensils are suitable for oven use.
Unsuitable utensils may break due to sudden
temperature change.
• Use care when opening oven door. Let hot air or steam
escape before removing or replacing food.
• Do not heat unopened food containers in oven.
Build-up of pressure may cause a container to burst
and result in injury.
• Place oven racks in desired location while oven is
cool. If a rack must be moved while oven is hot, use a
dry potholder.
• Do not use aluminum foil to line oven bottom or racks.
Aluminum foil can cause a fire or will seriously affect
baking results, and damage to porcelain surfaces.
• Do not touch interior surfaces of oven during or
immediately after use. Do not let clothing or other
flammable materials come in contact with bake or broil
burners.
• Other areas of the oven can become hot enough to
cause burns, such as vent openings, window, oven
door and oven racks.
• To avoid steam burns, do not use a wet sponge or
cloth to wipe up spills on a hot cooking area.
• Do not store combustible or flammable materials, such
as, gasoline or other flammable vapors and liquids
near or in the oven.
• Do not clean oven door gasket located on back of the
door. Gasket is necessary to seal the oven and can be
damaged as a result of rubbing or being moved.
• Do not drape towels or any materials on oven door
handles. These items may ignite causing a fire.
!
CAUTI ON
Do not store items of interest to children in cabinets
above the oven. Children may climb on oven to reach
these items and become seriously injured.

Important Safety Information
Baking, Broiling, and Roasting
• Do not use oven area for storage.
• Stand back from oven when opening door (when hot).
Hot air or steam can cause burns to hands, face, and
eyes.
• Do not use aluminum foil anywhere in the oven. This
could result in a fire hazard and damage the oven.
• Use only glass cookware appropriate for use in gas
ovens.
• Always remove broiler pan from oven when finished
broiling. Grease left in pan can catch fire if oven is
used without removing grease from the broiler pan.
• When broiling, keep meat away from flame! Meat that
is close to the flame may ignite. Trim any excess fat to
help prevent excessive flare-ups.
• Make sure broiler pan is placed correctly to reduce
any possibility of grease fires.
• Should a grease fire occur in the broiler pan, turn off
oven, and keep oven door closed until fire burns out.
Connecting Oven to Gas
Install manual shut-off valve in gas line for easy
accessibility outside the oven. Be aware of the location
of the shut-off valve.
Oven Safety Valve Oven valve is designed
to be a safety valve. Two
basic designs are used:
Hydraulic and Electric
Both types are safety
valves because they are
indirectly operated by
the oven thermostat,
which controls a pilot
flame or electric ignitor,
to open and close the
oven valve.
Grounded Oven Frame Ground prong on power
cord is connected to the
frame, usually a green
lead fastened by a
screw. In addition, any
part or component
capable of conducting
an electric current is
grounded by its
mounting.
Product Safety Devices
Safety devices and features have been engineered into
the product to protect consumer and servicer. Safety
devices must never be removed, bypassed, or altered in
such a manner as to defeat the purpose for which they
were intended.
Listed below are various safety devices together with the
reason each device is incorporated in the gas ranges.
Pressure Regulator Maintains proper and
steady gas pressure for
operation of oven
controls.
Regulator must be set
for the type of gas being
used: Natural or LP.
After servicing regulator,
make certain it is set
properly before
completing service.
Gas Burner Orifices Universal orifices are
used on most valves.
They must be adjusted
for the type of gas being
used: Natural or LP.
After servicing a valve
or orifice, verify proper
adjustment before
completing service.
If any ground wire,
screw, strap, nut, etc. is
removed for service, or
any reason, it must be
reconnected to its
original position with
original fastener before
the appliance is put into
operation again.
Failure to do so can
create a possible shock
hazard.

information.
Placement of the Oven
The oven must be placed in the kitchen or comparable
room. All safety guidelines must be followed and free air
flow around the oven is essential (see Chapter 2).
Do Not Block Air Vents
All air vents must be kept clear during cooking. If air
vents are covered during operation, the oven may
overheat. If this occurs, a sensitive, thermal safety device
automatically removes power to the oven, rendering the
oven inoperable. The oven will remain in this state until it
has sufficiently cooled.
