A. GENERAL INFORMATION
The Hauck StarJet Burner combines reliable operation with a unique, adjustable flame shaping
feature, eliminating the weight and maintenance problems of ignition tiles. Matching burner flame
shape to dryer design is the real secret to overall dryer efficiency. Some dryers work best with a
long, narrow, hard driving flame, while other dryers with the same rated capacity require a short
bushy, turbulent flame. Frequently, problems such as overheating of the combustion chamber,
excessive exhaust gas temperatures, and poor heat transfer can be eliminated by shaping the
burner flame. The burners in the StarJet series have an extremely wide range of flame shape
adjustment.
Burner air consists of primary air (atomizing air) and secondary air. Both are supplied by the
Hauck Turbo Blower. The plant exhaust air provides the remaining air required for complete
combustion and exhaust gas removal.
The StarJet will burn all clean commercial grades of fuel oil, natural gas, landfill gas, and liquid
propane. The burner provides a 7 to 1 turndown from the maximum firing rate.
Flight design in the combustion zone is important. The combustion zone should be clear of veiling
material and large enough to accommodate complete combustion. Consult Hauck for
recommended combustion zone requirements.
B. RECEIVING AND INSPECTION
Upon receipt, check each item on the bill of lading and/or invoice to determine that all equipment
has been received. A careful examination of all parts should be made to ascertain if there has
been any damage in shipment.
WARNING
This equipment is potentially dangerous with the possibility of serious personal injury
and property damage. Hauck Manufacturing Company recommends the use of flame
supervisory equipment and fuel safety shutoff valves. Furthermore, Hauck urges rigid
adherence to National Fire Protection Association (NFPA) standards and insurance
underwriter’s requirements. Operation and regular preventative maintenance of this
equipment should be performed only by properly trained and qualified personnel.
Annual review and upgrading of safety equipment is recommended.
NOTE
StarJet burners firing liquid propane and heavier
fuel oils could have less than 7 to 1 turndown.
IMPORTANT
If installation is delayed and the equipment is stored outside,
provide adequate protection as dictated by climate and period
of exposure. Special care should be given to all motors and
bearings, if applicable, to protect them from rain or excessive
moisture.

F. BURNER MOUNTING
Figure 7. Burner Mounting Tube Detail
1. The burner should be mounted on the drum centerline at the same pitch as the drum.
Install a structure to support and position the burner's skid. Burner repositioning may be
required for final burner adjustment.
2. Position the mini-skid on the support and securely bolt it in place.
3. Position the burner so that the distance from the inlet of the mounting tube to either the
bracket supporting the pilot, scanner and spin vane, or to the heatshield (whichever is
applicable) satisfies the “F” minimum dimension (see Figure 7).
4. Position the burner so that the end of the flame cone holder is flush with either the start of the
flared section or the open end of the burner mounting tube (whichever is applicable).
IMPORTANT
The pilot flame UV scanner must be aligned to view just
above the pilot as it passes through the flame holder
cone. The main flame UV scanner should be sighted just
over the edge of the flame holder cone, in line with the
flame.

5. Shim under the burner skid, if necessary, to align the burner horizontal and vertical
centerlines with the horizontal and vertical centerlines of the dryer drum (or combustion
chamber). The assembled burner must be on the combustion chamber centerline and
at the same pitch as the combustion chamber (follow the dryer manufacturer’s
recommendation for burners used without combustion chambers).
G. FUEL MANIFOLD INSTALLATION
The Long Nose StarJet burner system is supplied with a separate fuel valve manifold. Depending
on fuel or fuels specified, the manifold(s) will be designated as POM - Prepiped Oil Manifold,
Prepiped Gas Manifold, or PLPM - Prepiped Liquid Propane (LP) Manifold. Refer to dimension
drawings supplied for component dimensions.
IMPORTANT
Valve manifolds must be mounted in a horizontal position. Valves will not
function properly mounted vertically. Liquid fuel manifolds should not be
mounted above the burner centerline. POM and PLPM manifold should be
mounted as close to the burner as possible.
For all heavy fuel oil applications, i.e., any oil requiring heating for use, oil
piping must be heat traced (electric or steam) and insulated. Self-
regulating heat tracing is recommended to maintain the desired temperature
of a given fuel oil to achieve 90 SSU (1.8x10-5 m2/sec) or less at the burner.
Electrical heat tracing with a nominal rating of 12 W/ft (39 W/m) covered with
a nominal 2" (50mm) fiberglass type insulation is sufficient for most
applications. Fuel oil temperature should not exceed 250°F(120°C). Oil
viscosity should be checked prior to burner operation.
Hauck recommends the use of solid pipe to connect fuel manifolds to the
burner fuel inlets. Schedule 40 iron pipe is recommended for gas and oil
systems. LP applications require the use of schedule 80 pipe and
fittings rated for 350 psig (2410 kPa). Flexible hoses should not be used in
LP applications to connect to the burner fuel inlet.
Page 13
LNSJ -9
H. NATURAL GAS FUEL PIPING SYSTEM
1. Install a controlling gas regulator in the main gas line within 25 ft (7.6m) of the burner. For
optimum control, supply 15-25 psig (103 – 172 kPa) to this regulator. This regulator should
be sized to provide the required gas flow at the inlet of the burner manifold; 2 - 5 psig
(14 - 35 kPa) is a nominal expected gas pressure. Exact gas pressures will be set at start-up.
2. A manual equipment isolation valve, sediment trap and gas strainer must be installed
upstream of the gas control regulator to ensure compliance to NFPA requirements. The
manual equipment isolation valve facilitates servicing of the gas control regulator, sediment
trap, strainer, and sediment trap, strainer, and other components in the gas manifold.
3. The gas company should purge the main gas line to remove scale and dirt before it is
attached to the burner gas manifold.
4. Connect the main gas line (see Figure 8).
WARNING
It is important to remove the high velocity oil sleeve
and install the low velocity gas sleeve in the 360 –
750 model burners when firing natural gas.
NOTE
Hauck recommends the use of gas manifolds
that meet NFPA guidelines. NFPA requires
two safety shutoff valves wired in series, a
shutoff valve downstream of the second
(blocking) shutoff valve, and high and low gas
pressure switches that are interlocked with
the burner’s safety shutoff valves. Hauck gas
manifolds have been designed to ensure
compliance to NFPA requirements.
IMPORTANT
Install a flexible fitting in the gas manifold to reduce flexing of the manifold resulting
from plant vibrations. Be sure to install the gas metering orifice section (see
Figure 9) provided with the gas valve metering kit to measure gas flow.
Excluding the gas metering orifice section will make initial setup and tuning
difficult.

5. The piping from the gas regulator outlet to the burner gas manifold should be sized to
minimize pressure losses.
6. Check blower rotation. The impeller should rotate toward the blower discharge.
7. Inspect and operate the plant exhaust damper control. The exhaust damper should be
capable of maintaining a consistent negative pressure at the drum front bulkhead of
negative 0.2 to negative 0.5 "wc (negative 5 to negative 13mm wc) from low to high firing
rates for most applications.
8. Install a gas sampling probe in the dryer rear plate (see Application Sheet GJ73).
9. Set the low gas pressure switch to an initial setting of 0.5 psig (3.4 kPa).
10. Set the high gas pressure switch to an initial setting of 5 psig (34.5 kPa).
11. Complete the initial adjustment of the gas butterfly valve as follows: The valve is factory set
to travel 90 degrees from position 1 to position ‘Run’. This travel can be modified to increase
or decrease low fire by choosing a lower or higher starting point.
12. Open all manual shutoff valves in the gas line upstream of the gas pressure switch.
13. Start gas flow to the gas manifold.
14. Adjust the gas regulator until the pressure gauge upstream of the main gas automatic shutoff
valves indicates a pressure of 2 psig (13.8 k Pa).
15. High fire can be modified by increasing or decreasing gas pressure. After setting high fire
gas pressure, low fire must be rechecked. Refer to individual Burner Gas Orifice Meters
Graph for gas flows through the gas orifice meter (see Figure 10).
16. Burner flame adjustment spin vanes can be set at 0 to 60 degrees; 0 degrees narrows the
flame, 60 degrees widens the flame, and 30 degrees is a nominal starting point.
17. Burner air adjustments: (see Section P).
18. Recheck all linkages for tightness.
19. Install a U-tube manometer across the gas orifice meter taps.
20. Connect a gas analyzer to the gas sampling probe.
21. Exhaust gas readings should be taken with the burner firing at operating tonnage
(see Application Sheet GJ73).
WARNING
Adjustment of this equipment and its components by
unqualified personnel can result in fire, explosion, severe
personal injury, or even death.

see Table 3. For POM oil manifold installation instructions, see Section G.
Table 3. Minimum Pipe Size for Hauck Oil Supply Pumping Units
NOTE
Hauck requires the use of oil manifolds that meet
NFPA guidelines. NFPA requires two safety
shutoff valves piped in series in the burner’s main
oil line. A low/high oil pressure switch must be
interlocked with the burner’s safety shutoff valves.
WARNING
Adjustment of this equipment and its components by
unqualified personnel can result in fire, explosion,
severe personal injury, or even death.

2. Before attaching fuel oil lines, purge the piping to remove scale and dirt that could clog and
damage oil equipment.
3. Open all shutoff valves upstream of the fuel oil metering valve(s).
4. Be sure that the metering valve(s) is in the low fire position.
5. Open the mini-ball valve to the pressure gauge.
6. Slowly adjust the bypass relief valve until the initial set-up fuel oil pressure is achieved (see
Table 4). Final pump pressure will have to be adjusted to attain desired burner output and
stack exhaust gas analysis.

8. Inspect and operate the plant exhaust damper control. The exhaust damper should be
capable of maintaining a consistent negative pressure at the drum front bulkhead of
negative 0.2 to negative 0.5 "wc (negative 5 to negative 13mm wc) from low to high firing
rates for most applications.
9. The low/high oil pressure switch is factory set at a low set point of 15 psig (103 kPa) and a
high set point of 80 psig (552 kPa). Set point adjustments may be required depending on the
burner and fuel oil piping specifics.
10. Inspect the complete fuel oil system for leaks. Repair as necessary.
11. The burner oil metering valve is factory set to travel 90 degrees from position 1 to 10.
12. The low fire oil valve is manually set and regulates low fire flow. This valve can easily be
changed to regulate low fire oil flow. Start this valve at position 9. The low fire valve can
easily be cleaned:
a. Mark the valve pointer position.
b. Turn the valve counterclockwise to the ’clean’ position.
c. Return the valve pointer to its original position.
Page 19
LNSJ -9
13. High fire oil flow can be adjusted by increasing or decreasing fuel oil pressure. After
changing fuel oil pressure, low fire flow should be rechecked. Low and high fire rates in
gal/min or liters/min can be checked and recorded with the in-line oil flow meter provided
with the prepiped oil manifold.
14. Burner flame spin vane adjustment can be set at 0 to 60 degrees. 0 degrees narrows the
flame, 60 degrees widens the flame, and 30 degrees is a nominal starting point.
15. Burner air adjustments: (see Section P).
16. Recheck all linkages for tightness.
17. Connect a gas analyzer to the gas sampling probe (see Application Sheet GJ73). Exhaust
gas readings should be taken at operating tonnage.
