Maestro MEZZO MMZ430BS Installation Manual And Use And Care Manual - page 17
PREPARE THE INSTALLATION
For safety and optimum performance the vent hood must be installed above the cooking surface at 26”
minimum for an electric range and 30” for a gas cooking surface (If the instructions for installation of the
gas hob specify a greater distance, this has to be taken into account.)
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. 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.
