Safety Information
Safety Practices for Servicer
Before Installing
Safe and satisfactory operation of gas cooktops depend
upon its design and proper installation. However, there is
one more area of safety to be considered:
Installing the gas cooktop in compliance with local
electrical and gas building codes results in proper
operation and consumer satisfaction with the cooktop.
Servicing
Receiving Cooktop
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.
Inspect cooktop thoroughly at time of delivery.
Immediately report any visible damage to carrier. Damage
not discovered until after accepting delivery can still be
claimed by using a concealed damage report form,
available from the carrier's agent.
1. Gas smell—Extinguish any and all open flames and
open windows.
2. Turn gas off—Service cooktop with gas turned off
unless testing requires it.
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
cooktops 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
cooktops, especially when working on piping that
contains or has contained gas.
6. Check cooktop when service is completed—After
servicing, make visual checks on electrical
connection, and check for gas leaks. Inform
consumer of the condition of cooktop before leaving.
7. Adhere to all local regulations and codes when
performing service.
©2004 Maytag Services
All shipments, i.e., complete cooktop or parts, are
shipped at the buyer's risk. Maytag's responsibility ends
when the consignment is accepted by the carrier in
"good order." Maytag supports damage claims by
supplying invoices, bills of laden, and other
documentation as needed. providing this assistance,
however, does not imply any responsibility for settling
claims. Do not deduct claims for loss or damage from the
invoice and do not withhold payment pending adjustment
of claims. Do not return any units or parts for credit
without written consent.
Unpacking
• Open the carton and slide cooktop out of packing.
• Remove all literature packed with the cooktop and
place cooktop onto a protective flat surface.

If the burner flame is yellow or is noisy, the air/gas mixture may be incorrect. Contact
a service technician to adjust. (Adjustments are not covered by the warranty.)
With LP gas, some yellow tips on the flames are acceptable. This is normal and
adjustment is not necessary.
• With some types of gas, you may hear a “popping” sound when the surface burner
is turned off. This is a normal operating sound of the burner.
• If the control knob is turned very quickly from hi to lo, the flame may go out,
particularly if the burner is cold. If this occurs, turn the knob to the OFF position,
wait several seconds and relight the burner.
Do not operate the burners without a
pan on the grate. The grate’s porcelain finish may chip without a pan to
absorb the heat from the burner flame.
Although the burner grates are durable,
they will gradually lose their shine and/or
discolor, due to the high temperatures of
the gas flame.
• Leave a minimum of 11/2" between side of pan and surrounding surfaces such as
countertop, back splashes or side walls, to allow heat to escape and avoid possible
damage to these areas.
• To improve cooking efficiency and to prevent possible damage to the cooktop or pan,
the flame must be adjusted so it does not extend beyond the edge of the pan.
