hi e & c...
no doubt some1 has done this.
the issue is, stove exhaust fans (solo) are
12v so they can be used boondocking or whenever the GAS is on...
in fact most include a
12v light too.
combo microw'/vents are 115v/AC power, so no 115v ac means no exhaust fan or light over the gas range...
__________
the newest hood/fan/light combos from magic chef are very stylish...
and the typical freestanding microwave/convection ovens
can be mounted LOTS of places and do NOT require venting outside or a fan.
cheers
