The damper should be on the cold air side of the thermal break. The break should be as close as possible to where the ducting enters the heated portion of the house. • •••••Make up air: Local building codes may require the use of Make-Up Air Systems when using Ducted Ventilation Systems greater than specified CFM of air movement. The specified CFM varies from locale to locale.

Refer to “Ductwork installation guidelines Ductwork installation guidelinesDuctwork installation guidelinesDuctwork installation guidelinesDuctwork installation guidelines Ductwork installation guidelines” paragraph for further informations. • Install a wall cap with damper or roof cap at the exterior opening. Order the wall or roof cap and anytransition needed in advance. • Use 8" round metal ductwork only.

The hood must be secure to vertical studs in the wall, or to a horizontal support. • The vent hood should be on site before final framing and wall finishing. This will help to accurately locatethe duct work and electrical service. • Installation will be easier if the vent hood is installed before the cook-top and countertop are installed.

Ductwork installation guidelines For safety reasons, ducting should vent directly outdoors (not into an attic, underneath the house, into the garage or into any enclosed space). Keep duct runs as short and straight as possible. Duct fittings (elbows and transitions) reduce air flow efficiency. Back to back elbows and „S“ turns give very poor delivery and are not recommended. A short straight length of duct at the inlet of the remote blower gives the best delivery. Transition to duct from the integral blower or remote duct transition as close to the downdraft as is possible. In order of preference, use 1st. 10" round duct 2nd. 8" round duct 3rd. 3-1/4" x 14" duct 4th. 7" round duct 5th. 3-1/4" x l0" duct 6th. 6" round duct The use of flexible metal round duct should only be used when no other duct fitting exists. Limit use to short lengths and do not crush when making corners. .
