INSTALLATION DIMENSIONS
The Gemma chimneys are adjustable and designed to meet varying ceiling
heights as indicated in (FIGURE 4). The chimneys can be adjusted for
ceilings between 7' 7" and 8' 10 3/8" depending on the distance between
the bottom of the hood and the cooktop (distance x in FIGURE 4).

1. Disconnect and move freestanding range from cabinet
opening to provide easier access to upper cabinet and rear
wall. Put a thick, protective covering over cooktop, set-in
range or countertop to protect from damage or dirt.
2. Determine and clearly mark with a pencil the center line
on the wall where the rangehood will be installed.
3. Based on your ceiling height and/or personal

5. For the most secure installation, the MOUNTING
SCREWS (D in FIGURE 1) which mount the CANOPY
SECTION (A in FIGURE 1) should be installed into wood.
Mark the wall along the horizontal line 4 9/16" in from the
center line on either side (as indicated in X - FIGURE 5)

and install the MOUNTING SCREWS into the wall leav-
ing about 1/4" gap between the wall and the head of the
screw.
Determine the proper location for each bracket and install
the brackets on the wall. MAKE SURE THAT THE
BRACKETS ARE SECURELY FASTENED TO THE
WALL.
6. Determine and make all necessary cuts in the wall for
the ductwork. Install the ductwork before the rangehood
if ducting outside.
7. Determine the proper location for the Power Supply
Cable. Use a 1 1/4" Drill Bit to make this hole. Run the
Power Supply Cable. Use caulking to seal around the hole.
DO NOT turn on the power until installation is complete.
