For Mounting on a Cabinet with a Recessed Bottom
1) If you need to move the cooking range to work on the cabinet, turn off the power for an
electric range at the main electrical box. SHUT OFF THE GAS BEFORE MOVING A GAS
RANGE.
2) Measure the space (under the cabinet) between the inside front edge and inside back edge
(Fig. 3). With a saber saw, cut two wood filler strips (not included) to fill in the bottom of
the cabinet. Use 2-1/4” long wood screws (not included) to attach wood strips to the cabinet.
For metal cabinet, use 3/8” x 2-1/2” bolts and nuts to secure the strips to the cabinet. The
hood will be mounted on these filler strips. (For a more secure installation, you can also use
screws from inside the cabinet down into the wood filler strips.) Make sure the filler strips
do not cover the electrical power line access opening.
(Fig. 3)
3) Follow installation instructions from the section For Mounting on a Cabinet with a Flush
Bottom.
Installing the CH178 (42”)(48”) Hood
1) A minimum of 2 people should lift the CH 178 (42”) (48”) hood in installing under
cabinet to avoid injury and damage to the hood.
2) Proceed to the instructions from the section “For Mounting on a Cabinet with a flush
Bottom.”
For Venting the CH 178(48”) Hood
1) The CH7848 should be discharge upward to utilize the maximum power of the fan.
2) For vertical discharge, run ductwork between the hood locations to the roof cap.
For best result use a minimum number of transitions and elbows.
