The assembly passes through the roof plane via a roof curb sized per architectural drawings, fitted with an insulated curb cap. A combustion air intake and an exhaust vent penetrate the curb, each secured with a typical storm collar. The exhaust vent terminates at a vent exit cone and maintains a minimum three-foot clearance above the roof level.
