  • Page 5: Preliminary Information

    PRELIMINARY INFORMATION The most important single point in the successful operation of a York-Shipley Global burner is proper installation. Please read these instructions carefully before starting the installation. For special compo- nents and arrangements, refer to factory. Failure to follow these instructions and precautions could result in voiding the York-Shipley warranty on this product.

  • Page 6: Breeching, Stack And Draft Controls

    (in compliance with local requirements) is satisfactory. York-Shipley strongly recommends the use of round breechings (to avoid excessive noise and vibration) with gaskets and flanged joints. Boilers which are not normally sealed and gasketed must be inspected and measures taken to insure overall gas tight conditions including boiler proper, breeching connections, brick settings, etc.

  • Page 7: General Fuel Instructions

    GENERAL FUEL INSTRUCTIONS NV, FV-20 & FV-40 burners are designed for use with gas or #2 oil only, either separately or as dual fuel burners. Maximum oil viscosity; 40 SSU @ 100 F., 0.85 specific gravity. FUEL OIL SYSTEMS Fuel oil supply and return connections to system oil lines are made at or adjacent to the fuel oil pump on the burner.

  • Page 9: Gas Fuel Systems

    GAS FUEL SYSTEMS GAS TRAIN CONTROLS All gas burners are assumed to fire natural gas, 1000 btu/cu. ft., 0.6 specific gravity. For other fuels, consult the factory. All standard U/L gas trains for main flame include an upstream shut-off cock and electric gas valve, a downstream shut-off cock with test connection, and a gas volume control (butterfly) valve.

  • Page 17: Boiler Room Ventilation

    BOILER ROOM VENTILATION Each boiler requires sufficient fresh air to assist the combustion process. Insufficient air will result in smoky fires and large deposits of soot and carbon inside the boiler which will lower the boiler operating efficiency. There are times when incoming air is not desirable. These will be periods of normal shutdown of the equipment.

    STARTING INSTRUCTIONS To obtain the best burner operation, three adjustments are usually necessary: 1. The iris shutter that regulates the volume of air should be set to produce the proper flame color. Increasing the volume of air will produce a flame changing from yellow toward white. Too much air usually produces a fire having sparklers and can be detected by a strong odor.

  • Page 19: Yearly Service

    B. If Fire Is One Sided 1. Follow steps A-3 and A-4 and if fire is still one sided, install a new nozzle. C. If Fire Is Well Centered But Rough 1. Check oil pressure - standard setting 100 PSI. 2.
  • Page 20 NVA BURNERS (Full Modulation) After all pipelines have been tested and all electrical connections have been made, the fuses should be fastened in their proper places, the automatic controls adjusted to operate the burner, and the burner motor oiled with SAE No. 20 motor oil. There should be sufficient oil in the tank.
  • Page 21 GENERAL SERVICE If electrode setting is correct, clean nozzle as follows: a. Remove nozzle from nozzle adapter. b. Screw out nozzle strainer and insert. c. Wash all nozzle parts in very hot water or in carbon tetrachloride, making certain there are no dirt particles in the slots or nozzle orifice.
  • Page 22 E. If Fire Puffs on Start 1. Follow step A-3 2. Check for air leaks in suction line on suction side of fuel unit (See C-5). 3. On a two-pipe system, check for leaking check valve in suction line by putting pressure on suction line between fuel unit and check valve with a pressure gauge so placed as to show if pres- sure is holding or not.

The iris shutter that regulates the volume of air should be set to produce the proper flame color. Increasing the volume of air will produce a flame changing from yellow toward white. Too much air usually produces a fire having sparklers and can be detected by a strong odor.
  • Page 24 GENERAL SERVICE 5. Check transformer for proper spark as follows: a. Remove motor lead from transformer terminal. b. Remove nozzle pipe assembly from burner and connect buss bars to transformer clips. WARNING: BUSS BARS CARRY HIGH VOLTAGE - KEEP CLEAR OF THEM WHEN BURNER IS ON.
  • Page 25 GENERAL SERVICE F. If Fire Is Smoky 1. Increase air by rotating iris shutter to point where fire is clean. 2. Check for dirt and lint in fan wheel or at air intake. 3. Check for obstruction in chimney. 4. Clean nozzle as described under A-4. 5.
  • Page 26 FV-20 BURNERS 2. The oil pressure at the pump should be adjusted between 90 and 120 PSI. To get the best setting, vary the pressure between these two settings until needle on pressure gauge remains stationary or has the least movement. If gauge is not available, do not alter this setting more than 1-1/2 turns from the original setting.
  • Page 27 GENERAL SERVICE 7. Increase air by rotating air damper slightly. D. If After Fire or “Bump” Occurs on Shut-Down 1. Adjust nozzle pipe assembly to rear position (toward burner cover plate). 2. Make certain air is purged from fuel unit and nozzle pipe assembly. 3.
  • Page 28 FV-40 BURNERS After all pipelines have been tested and all electrical connections have been made, the fuses should be fastened in their proper places, the automatic controls adjusted to operate the burner, and the burner motor oiled with SAE No. 20 motor oil. There should be sufficient oil in the tank.

  • Page 32 GENERAL SERVICE Therefore, it is advisable to set proper gas rate with butterfly valve while keeping the main gas pressure regulator open 2/3 or less. This allows the regulator to work efficiently both at light-off and during the run. D. If main gas valve will not open after pilot is established, check to see that burner air switch contacts are made.
  • Page 33 NVBG BURNERS After all pipelines have been tested and all electrical connections have been made, the fuses should be fastened in their proper places, the automatic controls adjusted to operate the burner, and the burner motor oiled with SAE No. 20 motor oil. NOTE: Remove dust plug from bleed port of main valve.
  • Page 34 GENERAL SERVICE D. If main gas valve will not open after pilot is established, check to see that burner air switch contacts are made. When burner safety control is a TFM-2, this switch is connected between the terminals 6 and 8 of the control.

  • Page 37 STARTING INSTRUCTIONS Turn burner off and set fuel valve switch to “Oil”. Start burner and check light-off and combustion of oil fire. Since oil and gas rates are matched, an oil CO sample should be 10 to 11%. If air settings or fuel rates of either fuel are changed, combustion of both fuels should be rechecked.
  • Page 38 NVBGO BURNERS After all pipe lines have been tested and all electrical connections have been made, the fuses should be fastened in their proper places, the automatic controls adjusted to operate the burner, and the burner motor oiled with SAE No. 20 Motor Oil.

    The starting and operation of the burner is just as important as the installation. If a good installation is made but the unit is not properly started and the operator not properly instructed, maximum operating efficiency cannot be ob- tained. York-Shipley Global provides these instructions for the proper procedures of starting and maintaining the equipment.

Check grease level in bearings each month adding grease only if necessary. Too much grease may be just as damaging as too little. Housing should be at least 1/3 full, but never more than 2/3 full.

  • Page 45 FULLY MODULATED LIGHT OIL (#2) BURNERS USING PRESSURE ATOMIZATION (OPTION) As an optional arrangement, pressure atomized light oil burners are available for full range modulation. This is accomplished by using a by-passing nozzle which produces a variable firing rate by by-passing fuel from the nozzle swirl chamber. The nozzles are rated and stamped with capacity when operating at 100 PSI with the by-pass closed.
