In an in-wall heater, in which control equipmentis disposed in a side spaceon one lateral side of a combustion housingwithin an outer caseand an exhaust ductis disposed in a side spaceon the other lateral side of the combustion housing, the cooling performance of each of the side spaces is increased and noise due to a sucked-in sound of room air can be reduced. In a side plate portion of the outer caseon both lateral sides, an air intake opening, which is vertically long, is provided in a position in a front side portion exposed to a front of a room wall. Each side spacewithin the outer caseis formed in a ventilation flue on the suction side where the room air from each of the air intake openingsis conducted into the warm air fan

In-wall heater

A combustion safety device for the counter-action against oxygen deficiency in a gas heater which is provided with a main burner of the surface combustion type and with an oxygen-deficiency detecting burner of a Bunsen type, in which a primary-air hole of the oxygen deficiency detecting burner is made to communicate with the primary-air supply chamber or distributing chamber of the main burner.

Combustion safety device for a gas heater

A combustion safety arrangement in which a switch is connected in an electrical power circuit for an electromagnetic valve in a fuel passage. A combustion detecting element responds to a change of a flame caused by incomplete combustion or the like, and generates a signal or change in an electrical characteristic. The switch and the combustion detecting element are interconnected through a control circuit which has a level detector for detecting a predetermined level of the change in electrical characteristics. The arrangement is such that the switch may be opened by the predetermined level of the change in electrical characteristics. The control circuit has a time limit operation circuit so that only when the generation of the change in electrical characteristic is continued for a delayed time set by that time limit operation circuit, the switch may be opened. A timer circuit included in the control circuit is provided with a condenser which is charged through a resistance by closing a power switch in the electrical power circuit.
