ABSTRACT:
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.
