Module Cooktop Installation with 45" Downdraft


  • Is a support bracket required for the DD45 when installing cooktops or Module Cooktops?
  • Why is there no integrated module support bracket available for the DD45?
  • Why is a support bracket required for the DD30 but not the DD45?
  • Can the 45" Downdraft be installed with a single cooktop cutout that is less than the downdraft width?


Unlike Downdraft model DD30, model DD45 does not require an additional support bracket when installing 3 - 15" Module Cooktops or a 30" Cooktop with a 15" Module Cooktop.

  • The DD45I and DD45R have a support bracket built into the frame of the downdraft to support cooktop and module installation.
  • Models DD30I and DD30R do not have this support bracket built in.
  • New 14” Downdrafts (DD30, DD36, DD45) do not require a support bracket for use with a cooktop as they all have a rear support bracket built into them.
  • The support bracket runs the width of the downdraft, and the back edge of the cooktop sits on the edge of the bracket.
  • Downdraft model DD45 cannot be installed with a single cooktop. If the cooktop cutout is less than the downdraft, there is not enough space to insert the downdraft into position.
