La Cornue's US catalog is built around its handmade ranges and the matching Chateau hoods sold to sit above them, and the maker's own hood instructions read like a fitting job for two people rather than a quick drop-in: duct sizing, a minimum clearance above the burners, and a warning about depressurizing a kitchen that also burns gas. The La Cornue lineup ### Builds 1 appliance type Cooking appliances ### Called out for Hood Not Drawing Smoke: Duct Size, Damper and Makeup Air and 4 more problems on La Cornue ### Installations we do 10 installations, on any make Pre-installation site check · Gas hookup and leak check · Water supply and shutoff connection · Drain and air gap connection ### Error codes La Cornue publishes no setup codes for its ranges or Chateau hoods: both use mechanical dials, pilot ignition and simple switches rather than a digital control board, so there is no display to show a demo mode or an alert.

La Cornue's US line is cooking appliances only: its handmade ranges and the Chateau hoods built to hang above them, so an installation visit for this brand is always a range-and-hood fitting rather than a laundry, dishwasher or refrigeration job. ### A Chateau hood is installed by at least two people La Cornue's own installation guide for the Chateau hood says plainly that the hood is large and heavy enough that one installer working alone is not enough, and calls for safety gloves during the lift and mounting. ### Duct diameter has to match the hood's own outlet, not shrink The Chateau hood instructions warn against ducting that is smaller than the hood's outlet spigot, and call for the shortest run with the fewest bends, since more than two 90-degree turns measurably cuts performance. ### A powerful hood can starve a gas cooking appliance of air Because the range and its hood share the same kitchen, La Cornue's install guide requires enough make-up air that the negative pressure a running hood creates never exceeds a set limit, so the range's own burners keep drawing air correctly. ### Mounting height is set from the burners, not the counter The hood's recommended mounting distance is measured up from the range's own burners, with a shorter minimum distance specified for an electric cooktop than for a gas one, since overheating the hood body is the risk being managed. Parts The Chateau hood's blower and remote motor are treated as separate components from the hood body in La Cornue's own instructions, wired and ducted in before the decorative trim goes on, so an installer confirms the right blower model has arrived with the hood. Repair or replace A La Cornue range or hood that will not draw properly right after installation is almost always a ducting or clearance detail rather than a failed part, since the maker's own guide ties hood performance directly to duct length, diameter and bend count.

The maker's own installation guide says so directly, describing the hood as large and heavy enough that at least two people are needed to lift and mount it safely, with gloves recommended during the work. ### Can a La Cornue hood be ducted through a longer run to reach an outside wall? It can, but La Cornue's guide warns that a route with more than two 90-degree bends measurably degrades performance, so a longer, twistier run should use a larger duct diameter rather than the minimum size. ### Why does a gas cooking appliance burn poorly right after a new hood goes in? A high-performance hood can pull enough air out of the kitchen to affect a gas flame nearby, which is why La Cornue's install guide requires enough make-up air to keep the room's negative pressure under a set limit whenever a fuel-burning appliance is in the same space. --- **[Read on the site: La Cornue Appliance Installation](https://applianceinstallation.center/brands/la-cornue/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
