    VENTING PROBLEMS If the venting of any deck oven is either restricted or forced in any way the baking characteristics of the oven will be adversely affected. Examples of restricted venting include: • use of tees and elbows • long horizontal runs Insufficient make-up air can cause heated air and combustibles to remain in the oven shortening the life of the components.
