1. INTRODUCTION
This Instruction Manual contains a description of the type SP-48-NG/PG-FD gas pilot construction,
operation principle and the instructions for installation, start-up and service, including the industrial
health & safety recommendations.
The SP-48-NG/PG-FD-S/M/L (48 mm outer diameter, NG - Natural Gas or PG - Propane Gas, FD -
Forced Draught, S – Small, M – Medium, L – Large capacity range) gas pilot is a reliable and
effective source of ignition for oil and gas burners (see Appendix 1 – the pilot capacity vs. gas
pressure graphs).
S/M/L capacity ranges: Natural Gas: 20 ÷ 46 / 63 ÷ 132 / 84 ÷ 217 kW at 20 ÷ 80 kPa;
A sample of Pilot Part Number for Natural gas and Medium capacity is "SP-48-NG-FD-M-xxx", for
Propane gas and Large capacity range is "SP-48-PG-FD-L-xxx" (other Fuel gas on request) where
"-xxx" is the insertion length "L" from 0.5 to 3.0 metres.
The pilot is constructed of high quality materials and each unit is checked and tested before dispatch.
Acquaintance with the following instructions and strict attention to the indications reduce the
possibility of equipment failure to a minimum and ensure safety during normal operation.
2. OPERATION PRINCIPLE AND TECHNICAL SPECIFICATION
Unit construction provides
and cooling air. No moving parts ensure long, trouble-free operation with low maintenance costs.
Gas pilot type SP-48-NG/PG-FD-S/M/L.

- Page 2 The orifice-stabilizer assembly is optimized for Natural gas or Propane gas. In case of other Fuel gases contact Fireye as this may need the orifice replacement or changes to the assembly. Thanks to this principle of design, the pilot combustion zone is protected, the main combustion zone is outside the pilot, hence the air tube does not overheat and there is no need for retraction of the ignition device rod.

In case of the High Energy Spark Igniter, the rod tip should be placed further back ~ 50 mm back from the swirler-stabilizer.

7. INSTALLATION During the installation, all components have to be protected from impact or bending. Pilot SP-48-FD is designed such that it can be welded directly to the burner plate, or placed in the mounting tube (see Fig. 2). It should be noted that the distance from the gas head with mounting ring to the burner plate should be not less than 150 mm and insertion depth cannot exceed the “L”... - Page 6 ® In case of any doubts, the position of the pilot should be confirmed with the pilot and burner manufacturer. After determining the position of the complete pilot relative to the mounting tube, the mounting tube clamping screws should be tightened to prevent the device from moving.

Page 7: Operation
8.4 Power supply to the electrical circuit of the ignition device and spark or arc release should be allowed only after assembly of the device, and when installed in the operating position on the burner or outside the burner only to validate the operation strictly according to the device instructions e.g. - Page 8 ® 9.4 Setting the gas pressure at the correct level. 9.5 Starting of pilot trial for ignition sequence performed by the controller or in some cases by the operator: The correct setting of the main burner combustion air. Checking the interlock conditions before firing up. Providing power to the ignition source.

Page 9: Troubleshooting
Pull out the electrical igniter rod by loosening the ignition rod holding gland, only if it is absolutely necessary e.g. when rod is worn or damaged. Check and clean the bleed orifice and main nozzle. For cleaning use a soft copper wire. To remove heavy dirt use a soft wire brush e.g. -
