RTM states not to use an extension cord or use the deep fryer
outdoors. Okay, I get the safety around children, but miss why the
fryer cannot be used outdoors (under patio ) or with a short
extension cord?

No children at home or weather conditions that would cause a problem
for short term use outside and then moved back inside. The unit is
1800W 120V. Power is from a GFCI receptacle outside. UL approved
fryer.

What am I missing? I'm all ears.
