    Confidential and Proprietary Flue Connection Most Beech Ovens are supplied with either a Flue Transition or a Spray Filter. The main function of the Flue Transition is to form a transition from the oven spigot to a standard commercial flue duct connection point directly above the oven. The Spray Filter has the same properties as the Flue Transition though it has the added feature of a fine mist spray to remove particulate and dampen embers expelled from the oven.
