A:Answer Hello. We appreciate you letting us know of this situation with your double oven; we know a concern related to venting may be worrying, and we’d like to assist. This model is designed to vent from the bottom front; there is no need to also vent from the rear. We regret any inconvenience the bottom front vent may cause, but as long as the installation instructions and clearance needs were correctly followed, the venting from the bottom front should be working as it’s supposed to. A vent in the rear wouldn’t necessarily reduce or redirect the venting from the front. If it may help, the Installation Instructions are available if you go to our Café website, look up the model number, go to the product page and click the ‘For Owners’ link. We hope this helps to clarify the matter – if you have any other questions or concerns, we are happy to offer assistance any time. All the best! -Sarah@Cafe
