PURPOSE:To prevent the heat of combustion tube from being transferred to both sides of the heater and make a fan invisible from the outside of the heater by guide plates by a method wherein the guide plates are provided at both sides of rear part of the combustion tube to guide air from a warm-air fan to the sides of a fuel tank and electric parts for controlling, which are arranged at both sides of the combustion tube, and cool them. CONSTITUTION:The guide plates 33, 33 are provided so as to be protruded to both sides of rear part of combustion tube 29 of a burner for the warm-air space heater. When the fan 4 is driven, air is guided by the guide plates 33, 33 to both sides of the combustion tube 29 and cools the fuel tank 30 and the vicinity of electric parts for controlling the heater, which are arranged at both sides of the heater. The guide plates 33, 33 are provided to both sides of the combustion tube 29, therefore, the fan 6 is hidden by the guide plates 33, 33 and invisible from the outside of the heater when it is seen from the direction of a warm-air blow-off louver 2.
