2. INSTALLATION INSTRUCTIONS (continued)
PREPARING THE INSTALLATION

For household use only. Not to be used to exhaust explosive or dangerous fumes or materials.

For your safety and for optimum performance, refer to the 'Installation Drawings' for the distance
required between the cooktop and the range hood taking into consideration the height of the ceiling.
If the instructions for installation of the gas hob specify a greater distance, this has to be taken into
account as well.

The exhaust air must not be discharged into a chimney which is used for exhausting fumes from
other appliances burning gas or other fuels.

Determine the exact location of the vent hood. Mark
the location. Find the centerline of the cooktop. Use a
level to draw a vertical straight pencil line on the wall.

Plan the route for venting exhaust to the outdoors. Use the
shortest and straightest duct route possible. Make sure the
first duct runs is at least 12'' before redirecting. Long duct
runs, elbows and transitions will reduce the performance of
the hood. Use as few of them as possible. Larger ducting
may be required for longer duct runs.

Install a wall cap with damper or roof cap at the exterior
opening / wall. Join the wall or roof cap to the ductwork.

Connect round metal ductwork to cap and work back towards the hood
location. Use 2" metal foil duct tape to seal the joints.
