Abstract
An access door construction for a gas-fired water heater. The lower end of the outer jacket of the water heater is formed with an access opening and a door or panel bears against the outer surface of the jacket and encloses the opening. Tabs are formed on opposite side edges of the panel and engage the inner surface of the jacket adjacent the opening. In it unassembled condition, the panel is flat and when assembled with the cylindrical jacket, the resiliency of the panel will urge the tabs into tight engagement with the inner surface of the jacket. The panel is formed with a vertical channel having a generally semi-cylindrical cross section. By manually squeezing the sides of the channel together, the distance between the tabs will be decreased to thereby enable the panel to be removed and installed with the jacket.
