PURPOSE: A gas heater is provided to prevent damage to a igniter of a gas burner by counter inflow of air and to reduce the size of a combustion chamber. CONSTITUTION: A gas heater comprises a housing main body, a combustion chamber, a gas burner, a turbo fan, a hot air outlet, an exhaust control part, a distribution key board(26) and a rotation control panel(28). The combustion chamber is built in the housing main body. The gas burner is formed inside the combustion duct. The combustion duct is cylindrical shape. The connection duct has the turbo fan driven with a motor. The turbo fan discharges the heat of the connection duct to the hot air outlet. The exhaust control part is formed on the hot air outlet. The distribution key board is installed at a bifurcation of the branch duct. The rotation control panel is installed in a branch passage of the branch duct. |
