- 熱交換器の上端開口部に被冠されて該熱交換器を経て上昇する燃焼排気を前方に形成された排出口から排出する排気ダクト本体と、
該排気ダクト本体の内部で、該燃焼排気を、一旦該排出口と反対側に屈曲させた後に該排出口側に屈曲させて該排出口へ案内する整流板とを備え、
該整流板は、熱交換器の上端開口部に臨んで形成され、該熱交換器を経て上昇する燃焼排気を後方に案内する下方整流部と、該下方整流部に連続して形成され、該下方整流部に案内された排気を上方に案内しつつ該排出口側に屈曲させる屈曲整流部と、該屈曲整流部に連続して形成され、該屈曲整流部に案内された排気を該排出口側に案内する上方整流部とからなり、該上方整流部は、該下方整流部の上方に間隔を存して位置しており、
該下方整流部の前端縁部に、内周縁が上方に突出する複数のバーリング孔を備える熱交換器の排気ダクトにおいて、
該上方整流部の前端縁からバーリング孔を備える下方整流部の前端縁部より下方に垂下し、かつ、下方整流部の前端縁部との間に間隙を有し、該排出口から該バーリング孔を遮蔽する遮蔽部材を備えることを特徴とする熱交換器の排気ダクト。
