Features Highlights Ten-Year Warranty 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.) Quiet Operation Trane unit heaters incorporate an exceptionally balanced fan blade to assure quiet operation.
Features and Benefits Propeller Fan / Tubular Heat Exchanger Unit Heaters Trane has added a new unit heater to enhance its broad line of heating products. The Trane 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.
Features and Benefits Separated Combustion Propeller Fan Unit Heaters The Trane separated combustion propeller type unit heater keeps energy costs down by offering 80 percent thermal efficiencies. With model inputs available from 100 through 400 MBH, they are designed to be installed in mildly hostile environments where dusty, dirty and mildly corrosives exist or high humidity or slightly negative pressures prevail.
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 special orifice selections are required. Table 8, p. 24 contains correction factors that can be applied to the unit’s cataloged heating capacity, fan rpm, and fan bhp to obtain actual values for elevations above 2,000 feet. Corrosive Atmospheres Corrosion of heat exchangers and draft diverters have two basic variables—moisture (condensation) and sulphur. These two ingredients form to make sulfuric acid in the combustion process.
Application Considerations heated air being discharged toward the outside walls. Throw data for standard unit heaters and unit heaters utilizing optional discharge nozzles is shown in “General Data,” p. 20. Locations where extreme drafts can affect burner operation should be avoided. Strong drafts may cause pilot outage. Units with intermittent pilot ignition may be preferable in areas where drafts are likely. Minimum clearances required for accessibility and safety are listed in Table 2, p. 20.
Application Considerations distribution over a large floor area. (Five-way nozzles are not available on propeller fan unit heaters.) Indoor Units—Venting Gas fired indoor units require venting to remove the products of combustion. To help assure safe, trouble-free operation, follow the guidelines listed below: 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.
Application Considerations as standard equipment. However, for natural gas units, you need to specify on the order “Natural Gas, 100 percent shutoff.” 2. All units require AGA certification or UL “listed” controls. Our units are AGA certified and meet this requirement. 3. Models with inputs of 150,000 to 400,000 Btu require “mechanical exhaust” and a “safety interlock.” For our units, this means a power vented or drafter-equipped unit.
Application Considerations Table 1.
Application Considerations Figure 3. Power vented unit heater Mechanical venting occurs when a power blower provides a positive air flow to exhaust vent gas. The blower may be mounted at the unit heater or at the point of termination. With a factoryinstalled power venter, a pressure switch detects the flow of vent gas before the gas valve is allowed to open. With third party drafters, a centrifugal switch usually monitors the operation of the blower motor.
Application Considerations Beyond satisfying the codes, vents should be positioned away from shrubs and plants that might be affected by unseasonable warming by the exhaust. Sidewall vents release a considerable amount of water vapor that may condense on cold siding, adversely affecting painted surfaces. Placing these vents in locations that get natural air circulation from prevailing winds may help to reduce these negative effects. 1 2 1. Heat 2. Fumes 3.
Application Considerations temperatures. Use of PVC, CPVC and other plastic vent materials are inappropriate and hazardous. Check the manufacturer’s instructions before piping any appliance. The vent gases of power vented and separated combustion unit heaters may condense on a cold start-up or when vent piping runs through unheated areas. To protect the heater always pitch both intake and exhaust piping toward the outside of the building.
Selection Procedure Determine the total heating load requirements in accordance with methods recommended by the ASHRAE Handbook of Fundamentals or other acceptable means. High Efficiency 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.
Selection Procedure High Efficiency Duct Furnace 1. From the performance data tables, select the unit whose heating output meets or exceeds the heating load requirement. 2. Given the airflow to be supplied to the duct furnace, temperature rise and pressure drop through the duct furnace can be read directly from the performance data charts. If the air temperature rise is below 30°F, some supply air must be bypassed around the duct furnace.

Controls Pilot Control 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. Intermittent pilot ignition contains a solid-state ignition control system that ignites the pilot by spark for each cycle of operation. When the pilot flame is proven, the main burner valve opens to allow gas flow to the burners.
Controls Electronic Modulating, 4–20 mA/0–10 Vdc Input Provides modulated heat output. Ignition is at full fire (100 percent input), and modulates the gas input from 100 percent to 40 percent rated input. The modulating gas valve shall operate in response to a 4–20 mA or a 0–10 Vdc input from an external DDC control.
