CARE AND CLEANING

(continued)

Burner Assembly

The burner assemblies should be wiped clean often.

Turn all controls OFF before removing burner parts.

The electrode of the spark igniter is exposed 
when the top of the burner is removed. Be careful
not to push in any surface unit controls while the
top of a burner is removed. A slight electrical
shock might result which could cause you to 
knock over hot cookware.

CAUTION: DO NOT OPERATE THE BURNER
WITHOUT ALL BURNER PARTS IN PLACE.

The burner grates and caps can be lifted off, making
them easy to clean. Removing them gives you access
to the burner base and burner bowl. Wash the grate
and cap in hot, soapy water and rinse with clean
water. Dry them with a cloth—don’t reassemble them
wet. When replacing these parts, be sure they fit
securely into position over the burners.

Burner Grates

Cast-iron burner grates should be washed regularly
and, of course, after spillovers.

Wash them in hot, soapy water and rinse with clean
water. Dry the grates with a cloth—don’t put them
back on the cooktop wet. When replacing the grates,
be sure they’re positioned securely over the burners.

To get rid of burned-on food, place the grates in 
a covered container or plastic bag. Add 1/4 cup
ammonia and let them soak for 30 minutes. Wash,
rinse well, and dry.

To prevent rusting, apply a light coating of cooking
oil on the bottom of the grates.

Although they’re durable, the grates will
gradually lose their shine, 
regardless of the best care
you can give them. This is due to their continual
exposure to high temperatures.

Do not operate a burner for an extended period 
of time without cookware on the grate. 
The finish
on the grate may chip without cookware to absorb 
the heat.
