Duo-Therm Lighting Instructions

Duo-Therm's 901 is a gas furnace designed for use in recreational vehicles or mobile homes. The 901 uses liquid propane gas and is thermostat controlled. A 12-volt, DC blower wheel circulates hot air through two outlet air connectors for ducting through the recreational vehicle. BTU rating varies according to the volume of propane present in the supply tank. A 30-pound propane tank that is 50 percent full will provide approximately 22,600 BTU's per hour. The Duo-Therm features a direct spark ignition system to light the heater elements.
