P. LIQUID PROPANE (LP) FUEL PIPING SYSTEM
Adjustment of this equipment and its components by unqualified personnel can result
in fire, explosion, severe personal injury, or even death.
LP is highly flammable and heavier than air. It will accumulate near the ground in the
area of a leak and will dissipate relatively slowly. LP or Butane in its liquid state can
cause freezing and severe injury.
Eclipse does not recommend installation of a line-reducing regulator in the LP
supply line. If the regulator diaphragm were to total system pressure would be applied
to the burner and could result in damage to equipment, including the baghouse, and
result in serious injury to personnel.
Eclipse recommends the use of LP manifolds that meet NFPA guidelines. NFPA
requires two safety shutoff valves piped in series in the burner's main LP line. A
low/high pressure LP switch must be interlocked with the burner's safety shutoff
valves. Eclipse LP manifolds have been designed to ensure compliance to NFPA
requirements. All piping must be installed in compliance with applicable piping codes
and regulations. Equipment must meet the ratings for service as indicated in NFPA
58. Compressed air is required for the pneumatic LP shutoff valves if supplied.
1. LP or butane is supplied to the MegaStar™ burner in a liquid form and is vaporized as the
fuel exits the burner nozzles.
2. Eclipse recommends using a flexible connection to connect the LP line to the burner. A
flexible connection will reduce vibration stress on the LP connection. Refer to Table 12 for
recommended flex connection. Follow Figure 13 for the suggested piping layout.
MegaStar™ Model No.
Flexible LP Hose Part No.
3. Before attaching LP fuel lines, purge the lines with compressed air. Then, leak test piping
with compressed air.
4. Connect the main LP line at the appropriate connection on the burner skid. The capacity of
the LP fuel system should be 1.5 times the rated capacity of the burner.
5. If Eclipse has supplied the LP pump set for this application, consult the pump installation
instructions for information on the unit.
If the burner is being converted from natural gas or oil to LP firing, the diverter ring
located on the end of the primary air tube assembly must be removed (consult
Hauck service for details). Also, the LP nozzle must be removed prior to converting
the burner to natural gas firing to avoid damage to the LP nozzle.
