Abstract: A gas fireplace includes a firebox, a translucent cover provided on the firebox, and a separate assembly. The separate assembly is provided in the firebox, and divides the firebox into an air chamber and a combustion chamber which corresponds to the translucent cover. An exhaust passage is formed between the separate assembly and the translucent cover, and communicates the air chamber and the combustion chamber, wherein an inner width of the exhaust passage gradually reduces from the air chamber toward the combustion chamber. During the combustion, the exhaust passage guides cold air to flow through the semi-enclosed air chamber, and to evenly blow into the translucent cover, which forms an even air curtain on a surface of a bottom portion of the translucent cover to block out the heat. Whereby, the temperature of the translucent cover and the bottom portion of the combustion chamber could be lowered.
