Another first. Just completing another residentual project and about to install and wire a convection oven/gas cooktop combination. This unit was purchased at a local retailer and special ordered. Manufactured By Amana. Guess what no nameplate, no UL listing, no KW rating, no accompaning manuals,schematics not attached, nothing. Appears to have the typical 4 wire attachment for a conventional range, wiring at terminals 12 gauge stranded. Local retailer has no information, nor their supplier. The manufacturer cannot elaborate on the specs without at least a model number or style name (there are none, not even on the shipping order) and the owner has no idea on the model style or number because he's lost the original invoice. Occupancy is in 3 days what would you do??
