Reznor Reznor® EEDU Series Indoor Duct Furnaces Model EEDU75

Reznor® Venturion® EEDU series 80% thermal efficient indoor duct furnaces were developed to provide an annual fuel use improvement of up to 25% when compared with gravity-vented duct furnaces. The use of a factory-installed power venter, with metered combustion air, limits burner flue losses while reducing the required vent pipe size. A sealed vent product collection chamber, in lieu of a draft diverter, reduces the loss of dilution air from the room in both the on and off cycles. The series EEDU duct furnaces are available for use with either natural or propane gas, as specified, in sizes from 75,000 through 400,000BTUH gas input. They are designed for use as heating components in heating, heating/cooling, or makeup air systems and require a separate blower system for air delivery. The furnace has a Reznor® Thermocore® aluminized steel heat exchanger with venturi-design tubes. The die formed burners are of aluminized steel and include flared ports with stainless steel insert. The EEDU model is approved for temperature rise range of 50° to 90°F and includes "finger-baffles" for proper air distribution at these lower air volumes. Included as standard on the EEDU series are an intermittent sparkpilot and a single-stage 24-volt gas valve. Model EEDU series units are designed for field connection to a 24-volt thermostat for automatic operation. All required limit and safety controls are provided, including a combustion air pressure switch, which verifies proper vent flow prior to allowing operation of the gas valve.
