1100 cfm may be adequate, but I'd certainly question the 36.5" over a 48" range?

As Cookncarpenter says, Power is acceptable, 1200 cfm would be more normal.

Width is not.. you should be looking for an insert with a minimum width of 46" preferably 52" if you can make that work.

Depth is also a concern there. I would recommend the Best CP37I482 at minimum or a CP57IQT52SB. Those are 22.5" deep inserts which has a ton more coverage area. Worst case there is also a PK2245 which is the same, but around 43" wide (i can't recall exact width but its in that neighborhood).

Ventahood is another quality option. BH346PSLDSS or the larger 352 model. You can also step up to the BH4 which has a little more power.
