1. INTRODUCTION
This Instruction Manual contains a description of the type
operation principle and the instructions for installation, start-up and service, including the industrial health & safety
recommendations.
The
SP-32-NG/PG-ND (32 mm outer diameter, NG - Natural Gas or PG - Propane Gas or LPG, ND - Natural
Draught) gas pilot
is a reliable and effective source of ignition for oil and gas burners.
Pilot Part Number for Natural Gas is "SP-32-NG-ND-xxx", for Propane Gas or LPG gas is "SP-32-PG-ND-xxx"
where "-xxx" is the insertion length "L" from 0.5 to 2.0 metres. (see Appendix 1 – the pilot capacity vs. gas pressure
graphs for Natural gas and Propane). For other Fuel gas types or capacity ranges – see p. 11 Ordering Information
for Special Pilots Part Numbering approach.
The pilot is constructed of high quality materials, and each unit is checked and tested before
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.

INTRODUCTION SureFire II™ This Instruction Manual contains a description of the type SP-32-NG/PG-ND gas pilot construction, operation principle and the instructions for installation, start-up and service, including the industrial health & safety recommendations.
- Page 2 Orifice-stabilizer assembly is optimized for Natural gas or Propane gas/LPG. In case of other Fuel gas type or other capacity needed contact Fireye as this may need the pilot construction changes - see p. 11 for Special Pilots. Ignition is initiated by a spark or an electric arc generated at the tip of the igniter rod before stabilizer. The pilot flame stabilizes at stabilizer plate with holes while the main flame stabilizes in the primary combustion zone, at the outlet of the air tube.
- Page 3 ® 3. MOUNTING TUBES For fixing the pilot burner to a burner plate there are two types of mounting tube (material: carbon steel), offered as an optional accessory and to be ordered separately (see Fig. 2): a flange mounting tube allowing the fixing of a gas pilot without the use of welding, to be fixed with bolts to the burner plate.

® WARNING: ALL ACTIONS RELATED TO THE INSTALLATION, SERVICE AND OPERATION OF GAS PILOT MAY ONLY BE CARRIED OUT BY A TRAINED AND QUALIFIED PERSONNEL. WARNING: STRICTLY OBSERVE THE TEMPERATURE LIMITS FOR PILOT AND IGNITER ROD MOUNTED INSIDE. IN THE CASE OF EXPECTED WORK AT THE LIMIT OF PERMISSIBLE OPERATING TEMPERATURES, APPROPRIATE MEASURES SHOULD BE TAKEN (E.G. -
Page 6: Gas Supply Installation
® Only after proper rod positioning should the rod be fixed by tightening the gland and the whole gas assembly with rod inserted into the air tube. Mounting of electrical igniter rod in a pilot: unscrew the rod tip, disassemble the gland, put all gland parts on rod, insert the rod in gas head, screw back the rod tip and then set the appropriate tip position relative to an orifice-stabilizer assy. - Page 7 ® 8. PILOT START-UP, OPERATIONAL TESTS Before proceeding with the start-up and operational tests of SP-32-NG/PG-ND pilot check the following: 8.1 Gas installation is correctly connected, tight and functionally checked, including: valves, flaps, strainers, fittings and joints (flanged and screwed) as well as control and interlock devices. 8.2 Gas connection to the pilot made in accordance with the above instructions and the assembly drawing.

Page 9: Inspection And Maintenance
® 10.1 INSPECTION AND MAINTENANCE SP-32-NG/PG-ND pilot because of simple design does not require complicated maintenance procedures. Checking and cleaning of air and gas tubes: Close the manual gas valve and disconnect the pilot gas line. Disconnect the ignition rod electric supply cable. Unscrew the mounting ring. - Page 10 ® 11.2 In case of air tube wear or damage: if air tube has to be replaced - order a replacement air tube (without mounting ring) of length “L” – prices on request only, if just the end of air tube is eroded - cut 200 mm of the tube tip, order and weld spare part P/N SP-32-ND-END - replacement air tube end, length 200 mm, SS310/330.
