An adjustable duct coupling and deformable gasket let one venting assembly fit varied water heater duct layouts while enabling flue gas checks.

By integrating the combustion air duct into the wall plate, this case cuts wall clearance, hides the duct, and cools the plate during stove operation.

A wall bracket and movable blanking plate let a coaxial flue connect from the rear without opening the heater housing.
