After our report, the manufacturer, Travis Industries, told us it linked the clogging problem to a fuel gate installed on a limited number of Leyden stoves. Travis says the fuel gate was added to address problems related to poor-quality fuel and is no longer installing the part as standard equipment, though the company still offers it to correct fuel-quality issues. Our subsequent tests show that removing the fuel gate appears to correct the clogging problem we experienced with longer, roughly 1½-inch pellets. If you experience clogging or other problems with your stove, contact the manufacturer ([email protected]) and the local authorized dealer for corrective action.
