Hello, this is my first post here and I'd like to start off by
thanking all of you for your great advice.

I've just bought a Dual-Fuel Frigidaire with a Gas-through-Ceramic
Glass Cooktop (that's how it is described in the literature). One of
the things I was looking forward to was making a pancake
breakfast on a griddle, the kind of griddle that covers two burners.
However, when I read my owners manual yesterday I was appalled to
read:

"CAUTION: DO NOT use two burner units to heat one large pan such as a
roaster or griddle, or allow cooking utensils to boil dry. The bottom
surface of the pan in either of these situations could cause
discoloring or crazing of the appliance cooking surface, and damage to
the grates and burner units."

I've never had a ceramic cooktop before, but to not allow a griddle to
be used on a cooktop seemed very strange to me, so I went to
www.frigidaire.com and looked up my model

http://www.frigidaire.com/products/c..._PLCS389DC.asp

I read the Owner's Manual listed on the page there (the one for my
model) and it says something different regarding using a griddle. It
says:

"WARNING: Do not use stove top grills on the burner grates of your
sealed gas burners. If you use a stove top grill on a sealed gas
burner, it will cause incomplete combustion and can result in exposure
to carbon monoxide levels above allowable current standards. This can
be hazardous to your health."

The Owner's Manual (the one on Frigidaire's web site) does not mention
anything about possible damage to the cooktop.

My question: Has anyone else come across this? Do any of you have a
ceramic cooktop with gas burners and use a griddle that covers two
burners? If so, I would be very interested whether it had any
noticeable effect on the ceramic cooktop.

Thank you for taking the time to read this!

Cheers,
Tara
