INTRODUCTION
The model 369RAN Furnaces are available in 2 sizes. Each size unit is capable of 3 heat/airflow combinations by a simple nozzle change. Unit 036105 covers inputs of 70,000, 91,000, and 105,000 Btuh, and unit 060120 covers inputs of 119,000, 140,000 and 154,000 Btuh. This eliminates the need to stock 6 separate units
This furnace is a multipoise unit. It may be installed in the upflow, downflow or horizontal configuration.
The furnace is shipped as a packaged unit, complete with burner and controls. It requires a line voltage (115 vac) connection to control box, a thermostat 
The air handling capacity of this furnace is designed for cooling airflow. Refer to Table 12 for expected airflows at various external duct static pressures.
