A smoke generator for smoke testing heat exchangers of gas furnaces for the presence or absence of leakage or fluid-tight integrity, the generator having: a smoke chamber housing having upper and lower portions; at least one heating element in the upper portion of the smoke chamber housing; a pump which supplies a gas to the smoke chamber housing; a liquid which fills the lower portion of the smoke chamber housing, wherein the at least one heating element is suspended above the liquid; an applicator of liquid to the at least one heating element; and a smoke vent in the upper portion of the smoke chamber housing. A method of smoke testing a heat exchanger of a gas furnace for the presence or absence of leakage or fluid-tight integrity, the method having the following steps: closing an intake and an outtake of the heat exchanger; fluidly communicating a smoke generator with the heat exchanger, wherein the smoke generator comprises: a smoke chamber housing having upper and lower portions, at least one heating element in the upper portion of the smoke chamber housing, a pump which supplies a gas to the smoke chamber housing, a liquid which fills the lower portion of the smoke chamber housing, wherein the at least one heating element is suspended above the liquid, an applicator of liquid to the at least one heating element, and a smoke vent in the upper portion of the smoke chamber housing; filling the heat exchanger with smoke from the smoke generator; and observing smoke exiting the heat exchanger.

[ The invention claimed is:] [1.] A smoke generator for smoke testing heat exchangers of gas furnaces so as to determine the presence or absence of leaks therein via observing any escape of a pressurized visible smoke tracer, the generator comprising:a smoke chamber housing having upper and lower portions;at least one heating element in the upper portion of said smoke chamber housing;a pump which supplies a pressurized carrier gas to the upper portion of said smoke chamber housing;a liquid which fills the lower portion of said smoke chamber housing, wherein said at least one heating element which generates a smoke vapor as a visible leak tracer is suspended above said liquid;an applicator of liquid to said at least one heating element; anda smoke vent in the upper portion of said smoke chamber housing which releases said smoke vapor and said pressurized carrier gas into said heat exchanger.
