BS high backguard/shelf oven vent location
I'm considering a Blue Star range with a high (24") backguard and high shelf. In this configuration, where does the oven vent:
at the height of the burners or
does the high backguard contain a channel to conduct oven gases through the shelf and vent directly above, or
something I'm not thinking of?
The range I'm considering comes with island trim so I'd have to discard that and purchase the high backguard. Do others recommend this high backguard/shelf configuration or should I just install a generic sheet of stainless and a stainless shelf to backsplash instead of these expensive BlueStar accessories?
