Special Pilots:  
Not all applications can be easily coded to cover every requirement. In order to provide for these, there is a 
supplementary Part Numbering system. It is used in case of applications that require: 
-  other Natural gas or Propane gas capacity ranges than standard needed, 
-  other Fuel gas than specified above 

– 

see Remarks in Appendix 3, 

-  other pilot construction needed. 
In such case please provide the data as in Table in Appendix 3, especially the gas composition. It is required 
for the proper selection of materials used for pilot construction and feasibility of operation checking. 
Part Number in such case is SP-32-ZYY-F-xxx where: 

Z

” is capacity range e.g. 

S

-small, 

M

-medium, 

L

-large or possibly others, 

YY

” is the specific 

Project Number 

given by Fireye after analyzing the Proposal Data Sheet, 

F

” is 

Forced draught

xxx

” is the length 

L

REMARKS: Fireye will provide a special price for the pilot after Proposal Data Sheet analysis. 

Fireye may refuse to execute of an order if considered as impossible to complete.
