Introduction 1. INTRODUCTION Product Description n The Phoenix VH (Velocity Heat) burner is a direct-fired nozzle-mix burner, that utilizes ambient combustion air to supply a focused high temperature flame with flexibility of fuel options. n The Phoenix VH burners are available with high velocity and medium velocity combustor options.
Introduction Major Components The Phoenix VH Burners consists of the following components (Refer to Figure 1.2): n Burner Body n Burner Nozzle n Burner Rear Cover n Combustor n Fuel Inlet Block n Air Inlet Block n Igniter n Flame Supervision...
Installation 2. INSTALLATION Handling n Verify that the area is clean. n Protect the burner from weather, dirt, and moisture. n Protect burner from excessive temperature and humidity. n Take care not to drop or damage the burner. Storage n Verify that the burner is clean and free of damage. n Store burner in a cool, clean, dry room.
Installation Checklist Before Installation Intake To admit fresh combustion air from outdoors, provide an opening in the room of at least one square inch per 4,000 BTU/hr. In the presence of corrosive fumes or materials in the surrounding environment, supply burner with clear air from an uncontaminated area or provide a filtering system which shall not impede burner operation.
Installation Rotate the Rear Cover (Optional) To rotate the rear cover, do the following (see Figure 2.1). n Disconnect the fuel piping at a union in the piping or the inlet block provided on the burner (1). n Remove the four bolts used to hold the fuel inlet (1). n Remove the inlet block, O-rings, and Orifice Plate from the rear cover (1).
Flame Supervision Igniter Figure 2.2 – Installing the Flame Supervision Phoenix VH burners are offered with UV scanner and flame rod flame supervision options. Check the Phoenix VH specification sheets for availability. Install the flame supervision into the ½” or ¾” NPT opening/adapter in the rear...
Installation Installing the Igniter Verify the gap between the center electrode and grounding rod is no less than 1.5mm and no more than 2.0mm. Install the igniter into the opening opposite to the flame supervision in the rear cover. CAUTION: Do NOT apply any assembly compound to the threads of the igniter.

Installation n The combustor shall not extend beyond the inside of the furnace wall more than 1”. Beyond this length it is necessary to add a spacer on the outside of the furnace to keep the end of the combustor within 1” of the furnace wall.
Installation Alloy Combustor Mount the burner to the chamber wall using customer supplied M10 X 1.5mm bolts (4x) and M10 lock washers (4x), or equivalent. Verify that the mounting gasket (1) that was supplied with the burner is installed between the burner and the chamber wall (2). Verify that the mounting gasket (1) does not leak.
Installation Silicon Carbide (SiC) Combustor Mount the burner to the chamber wall using customer supplied M10 X 1.5mm bolts (4x) and M10 lock washers (4x), or equivalent. Verify that a mounting gasket (1) is installed between the burner flange and chamber wall (2). Verify that the supplied retaining ring gasket (5) is installed between the SiC combustor and retaining ring (6).
Installation Refractory Combustor Verify that a mounting gasket (1) is installed between the burner flange and the refractory combustor (2). Mount the burner onto the threaded studs on the refractory combustor and fasten the nuts included with the refractory combustor in a crosswise manner and torque to a minimum of 20 ft.lbs and maximum of 25 ft.lbs.
Installation Large Refractory Combustors n On burners VH500 and larger, the refractory combustor must be tightly surrounded by a collar made of brick, plastic refractory, or a castable refractory of at least 4” (100mm) minimum thickness on all sides of the combustor.
Installation Checklist After Installation To verify proper system installation, do the following: n Verify that there are no leaks in the gas and air lines. n Verify all components of the flame monitoring control system are properly installed. This includes verifying that all switches are installed in the correct locations and all wiring, pressure and impulse lines are properly connected.
Operation 3. OPERATION Initial Setup n Fully open the main air valve. n Startup combustion air supply. n Adjust the control valve in the air supply line to the air differential pressure between taps A and B to the stated pressure for high fire in the Phoenix VH specification sheet.
Use a small flat hear screwdriver to open pressure taps A and B. n Attach manometer to taps A and B. n Adjust air valve until differential pressure is at required value specified in Phoenix VH Specification Sheet. Remove manometer and close pressure taps A and B.
Operation On-ratio Gas Systems (Air Flow) n Adjust air valve to low fire. n Use a small flathead screwdriver to open pressure taps A and B. n Connect manometer to taps A and B. n Adjust air valve until differential pressure is approximately 0.2” WC. On-ratio Gas Systems (Gas Flow) n Turn the gas flow limiting valve to 50% open.
Operation Manual Startup Guide n Startup combustion air supply. n Open gas shut-off valve and start ignition sequence. n Visually check for flame to confirm that burner has lit. DANGER: If no flame can be seen, close the gas valve to stop gas flow. Allow flame safety to purge the body of gas before attempting to restart the burner.
Maintenance 4. MAINTENANCE Preventative maintenance is the key to a reliable, safe, and efficient system. The core of any preventive maintenance system is a list of periodic tasks. The following are suggestions for monthly and annual checks: NOTE: The monthly and yearly lists are an average interval. In the case of a dirty environment, service interval may need to be shortened.
Maintenance Annual Checklist n Inspect flame supervision devices for good condition and cleanliness. n Check for proper inlet air/gas ratios. n Test all the alarm systems for proper signals. n Check igniters for proper gap. n Check valve motors and control valves for free, smooth action and adjustment.
Troubleshooting 5. TROUBLESHOOTING Troubleshooting Procedures Potential Problem Possible Cause Proposed Solution Cannot initiate Start-up Malfunction of flame monitoring Have a qualified electrician sequence. control system such as shorted investigate and solve. out flame sensor or electrical noise in sensor line. Flame safety purge cycle not Check flame monitoring control completed.
