Features Highlights Ten-Year Warranty Burners The complete heat exchanger, draft hood assembly of the unit heater and burners are warranted by Trane to be free from defects in material and workmanship for a period of 10 years from the date of manufacture. (Warranty not applicable on duct furnaces or Separated Combustion units.
Features and Benefits High-Efficiency Propeller High-Efficiency Centrifugal High Efficiency Indoor Duct Furnace Fan Unit Heaters Fan Unit Heaters Trane high-efficiency propeller fan unit heaters achieve annual fuel savings of 20 to 25 percent over conventional gravity vented heaters. Each unit features a factory-installed flue vent fan and sealed flue collector that controls combustion and excess air during the on-cycle. The high-efficiency centrifugal fan unit heater keeps energy costs down.
Features and Benefits Propeller Fan Unit Heaters The Trane gas-fired unit heater is a complete heat generating and distributing plant, equipped with automatic safety controls, all packaged in a modern, streamlined, space saving, attractive casing for mounting near the ceiling. Propeller units are basically zero static pressure appliances. At no time should ductwork be used with propeller units. The designs are certified by AGA and CGA as conforming with standards for safe and efficient performance.
Features and Benefits Tubular Heat Exchanger Propeller Fan Unit Heaters TheTrane Company has added a new unit heater to enhance its broad line of heating products.TheTrane tubular heat exchanger is a very durable unit heater that provides an alternative to the traditional clam shell style.These are propeller style units that combine the latest tubular heat exchanger style with inshot burner technology to create a very efficient operating unit.
Application Considerations General Propeller fan unit heaters and centrifugal fan unit heaters are designed for use in space heating applications.The units are typically used in areas with high ceilings, and are exposed in the space to be heated. Unit heaters offer low installed cost, and are able to heat large volume areas without requiring extensive duct systems. Duct furnaces are designed for use in ducted applications with a separate air handling device such as a horizontal blower assembly.
Application Considerations Indoor Units Throw Data Indoor gas unit heaters and duct furnaces are used primarily in commercial and industrial structures such as manufacturing areas, warehouses, garages, stores, showrooms, lobbies and corridors. Throw data for units with standard louvers and for units with optional discharge nozzles are in the General Data section, pages 19 and 20. Optional nozzles are for use on propeller fan unit heaters, centrifugal fan unit heaters and duct furnaces.
Application Considerations Power Vented Units Units with a factory installed flue vent fan. 1 All units must be vented. Power vented units are designed to use single wallvent pipe. A BreidertType L, Field Starkap, or equivalent unit vent cap must be furnished by the customer. 2 The venting system for these appliances shall terminate at least 4 feet below, 4 feet horizontally from, or 1 foot above any door, window or gravity air inlet into any building.
Application Considerations Minimum/Maximum Gas Inlet Pressures Gas valves are suitable to a maximum inlet pressure of 0.5 psi (14 inches water column) on natural gas. If the main gas supply pressure is greater than 14 inches W.C., a step-down pressure regulator must be field installed ahead of the gas valve. Minimum inlet pressure for natural gas units is 5 inches W.C. For LP (propane) gas, the minimum inlet pressure is 11.0 inches W.C. and the maximum inlet pressure is 14.0 inches W.C.
Application Considerations Mounting Detail (Hanging Hardware Supplied by Others) Steel Construction Wood Construction 12 UH-PRC002-EN
Venting unit heaters and duct furnaces used to be as simple as remembering that warm air rises. With the introduction of new venting equipment and safety controls, things have become a little more technical.Today’s contractor has to know a lot more about proper venting to get the job done within code at a reasonable price. For starters ANSI now categorizes vented appliances into four categories.
Application Considerations Power Vented Unit Heaters (Venting Unit Heaters) Power Vented Unit Heater Mechanically vented appliances have enjoyed increasing acceptance in American facilities. Power vented unit heaters allow installation without the need to penetrate expensive roofing materials. They also offer more flexibility in placement of individual unit heaters. Mechanical venting occurs when a power blower provides a positive air flow to exhaust vent gas.
Heat Fumes Humidity Application Considerations (Venting Unit Heaters) Contractors must also be aware of the conditions at the point of termination. The National Fuel Gas Code NFPA 54/ ANSI Z223.1-1992 mandates that vent system should terminate at least 4 feet below, 4 feet horizontally or 1 foot above any window, door, or gravity inlet to a building.Termination with a vent cap approved by the manufacturer should occur well above the snow line.
Selection Procedure Determine the total heating load requirements in accordance with methods recommended by the ASHRAE Handbook of Fundamentals or other acceptable means. Propeller Fan Unit Heater 1 From the performance data tables, select the unit whose heating output meets or exceeds the heating load requirement. 2 Airflow (cfm) and temperature rise can be read directly from the performance data tables. 3 Knowing the mounting height of the unit, throw can be determined from the performance data table.

High efficiency units (centrifugal, propeller and duct furnaces) ship as standard with intermittent pilot ignition.The separated combustion propeller and centrifugal fan unit heaters also ship as standard with intermittent pilot ignition. Indoor gas heating units are provided with an automatic single-stage gas valve as standard.

Electric Power Sequence of Operation Typical wiring diagrams and sequence of operations for indoor units with intermittent pilot ignition are shown below. On duct furnaces, the fan motor and associated controls shown in the wiring diagrams are not integral to the unit. It is essential, however, that the air handling system be interlocked with the duct furnace to prevent duct furnace operation without airflow. Single-Stage Control With power applied to the unit: 1 The thermostat calls for heat.
Electric Power Two-Stage Control With power applied to the unit: 1 The first stage of the thermostat calls for heat. 2 The pilot valve opens. 3 The ignitor sparks continuously to ignite the pilot. 4 The sensor proves pilot ignition and shuts off the ignitor. 5 With the pilot lit, the main gas valve opens to low fire. 6 Main burners are lit at 50 percent of unit’s rated input. 7 The fan time delay relay (optional on duct furnaces) allows the heat exchanger to come up to operating temperature.
Electric Power Hydraulic Modulating Control With power applied to the unit: 1 The thermostat calls for heat. NOTE: If a thermostat is not supplied, steps 2 through 5 will be constant as long as power is applied to the unit. 2 The pilot valve opens. 3 The ignitor sparks continuously to ignite the pilot. 4 The sensor proves pilot ignition and shuts off the ignitor. 5 With the pilot lit, the main electric gas valve opens. At this time, the fan time delay (optional on duct furnaces) is energized.
