INTRODUCTION

The model 58CMA Furnaces are available in 2 sizes. Each size
unit is capable of 3 heat/airflow combinations by a simple nozzle
change. Unit 105-12 covers inputs of 70,000, 91,000, and 105,000
Btuh, and unit 120-20 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 hook-up as shown on wiring diagram, oil
line connection(s), adequate duct work, and connection to a
properly sized vent.
