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-FD (32 mm outer diameter, NG - Natural Gas or PG - Propane Gas or LPG, FD - forced draught)
gas pilot is a reliable and effective source of ignition for oil and gas burners.
Pilot Part Number for Natural Gas is "SP-48-NG-FD-xxx", for Propane Gas or LPG gas is "SP-48-PG-FD-xxx"
where "-xxx" is the insertion length "L" from 0.5 to 3.0 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 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.

    304/316 SS and heat-resistant steel 310/330 SS Notes: 1. If the above parameters are different than those required please contact Fireye 2. For Imperial Units please refer to the Appendix 4 Unit Conversion Table 3. Device complies with the requirements of the European Directive 2011/65/EU (RoHS 2)

  • Page 5: Appendix 2 Should Be Strictly Observed

    WARNING: ALL ACTIONS RELATED TO THE INSTALLATION, SERVICE AND OPERATION OF GAS PILOT MAY ONLY BE CARRIED OUT BY A TRAINED AND QUALIFIED PERSONNEL. REMARK: IN CASE OF ANY DOUBTS REGARDING INSTALLATION OF THE PILOT CONSULT WITH THE MANUFACTURER. INSTALLATION During the installation, all components have to be protected from impact or bending.
  • Page 6 It should be remembered that the rod tip positioning against the stabilizer plate in the pilot gas part assembly (pos. 3 on Fig.1) should be done outside the air tube only. 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.
