Preparation Before Installation 
NOTE: TO AVOID DAMAGE TO YOUR HOOD, PREVENT 
DEBRIS FROM ENTERING THE VENT OPENING. 
Decide the location of the venting pipe from the hood to the 
outside. Refer to Figure 1. 
A straight, short vent run will allow the hood to perform more 
efficiently. 
Try to avoid as many transitions, elbows, and long run as 
possible. This may reduce the performance of the hood. 
Temporarily wire the hood to test for proper operation before 
installing. 
Important: Peel protective film off the hood, if any. 
Use duct tape to seal joints between pipe sections. 
 CAUTION: If moving the cooking range is necessary to 
install the hood, turn off the power in an electric range at 
the main electrical box. SHUT OFF THE GAS BEFORE 
MOVING A GAS RANGE. And use a protective covering 
to protect cooktop and/or countertop from damage. 
Custom Hood Preparation 
1. The custom hood frame must be designed based on the 
shape and the weight of the hood. Refer to Measurements 
and Diagrams of hood on Page 13-15. 
2. A sturdy base (3/4 inch thick plywood recommended) is 
needed to sustain the weight of hood. 
3. It is recommended to install front & rear stud support (not 
included). Refer to Figure 2. For safety purposes, extra 
installation holes on the side of the hood 
Prepare the side stud support if needed. 
4. Determine and mark the centerlines on the base of the wood 
frame where the hood will be installed. 
5. Determine the 
proper location for the Power Supply Cable. 
Make a wiring access hole using a drill bit. Install the wire 
cable and seal the gap around hole. 
6. Cut out the opening where the hood will be installed. (Refer to 
Figure 3 for appropriate dimensions based on width of hood.)
Wiring to Power Supply 
CAUTION: If moving the cooking range is necessary to 
install the hood, turn off the power in an electric range at 
the main electrical box. SHUT OFF THE GAS BEFORE 
MOVING A GAS RANGE. RISK OF ELECTRICAL SHOCK. 
TH
IS RANGE HOOD MUST BE PROPERLY GROUNDED. 
MAKE SURE THIS IS DONE BYQUALIFIED ELECTRICIAN 
IN ACCORDANCE WITH ALL APPLICABLE NATIONAL 
AND LOCAL ELECTRICAL CODES. BEFORE 
CONNECTING WIRES, SWITCH POWER OFF AT 
SERVICE PANEL AND LOCK SERVICE PANEL TO 
PREVENT POWER FROM BEING SWITCHED ON 
ACCIDENTALLY.
