If this is not done, flame disturbance canresult which can lead to flame impingement on the heat exchangerand eventually heat exchanger failure. It can also cause pilotoutage problems leading to nuisance service calls or loss of heat inthe structure.If the Fan-Jet end of the structure is colder than the remainder of thestructure, correct by adjusting one or two of the lower louvers of theheater to a downward position to divert part of the heated air to theend wall area.CAUTION: Avoid combustion malfunctions when two heaters areused with one Fan-Jet. The minimum heater from Fan-Jet openingdistance must be maintained. Both heaters must operatesimultaneously, unless center baffle is used and the dischargelouvers must be directed toward the top of the Fan-Jet opening.CAUTION! These units have rotating parts and safety precautionsshould be exercised during installation, operation andmaintenance.Notice. In cases where motor with capacitor is used, the motorbase screws must be loosened and the motor housing rotated suchthat the capacitor is approximately 45 degrees above the horizontalposition when viewing the shaft end of the motor as shown in Figure1 on Page 2.1. These instructions are intended to be used in conjunction withthe installation instructions for the Fan-Jet convection tubesystem which comes attached to the Fan-Jet unit. Follow thelocation and framing in the Fan-Jet instructions and theinstallation instructions that come with the unit heater.2. The horizontal struts shipped with the Fan-Jet will not be usedwith the heating accessory. The proper spacing of the Fan-Jetunit will be accomplished with the heat intake top and bottompieces and the diagonal extended struts shipped with theFan-Jet.3. The heat shield should be assembled to the Fan-Jet unit usingthe appropriate exploded view (shown on page 2) as a guide.4. The Fan-Jet unit should now be supported as indicated in items8 and 9 of the Fan-Jet instructions, Form 610001.5. Attach the heat shield assembly to the framed opening with thefasteners provided.6. Continue with the installation of the tubing as directed in items12 through 32 of the Fan-Jet Installation Instructions 610001.The center baffle must be installed whenever two unit heatersare used with a Fan-Jet unit and are staged to operate atseparate times. The baffle will prevent “blow thru” from one unitheater to the second that may result in reverse rotation of thesecond heater fan or may affect the pilot light of the secondheater.FAN-JET PERFORMANCE DATAFramed opening furnished by others.* The output BTU rating of gas fired heaters is 80% of their input BTU rating.See CAUTION* |
