1.  INTRODUCTION 

This Instruction Manual contains a description of the type 

SureFire II

 HDHESI Heavy Duty High Energy Igniter 

construction, operation principle and the instructions for installation, start-up and service, including the industrial health 
& safety recommendations.  
Type 

HDHESI 

igniter is designed for direct ignition of gaseous or liquid fuels like light and medium oil, heavy oil 

which can be steam, air or mechanically atomized.  

The igniter creates 3 sparks per second of a very high energy of 24 Joules per spark, sufficient for self-cleaning 
of the rod tip and for direct firing of heavy fuels in particularly difficult operating conditions 

e.g. in wet, dirty 

(slag, ash, unburned fuel) environment.  
In case of special fuels or difficult operating conditions consult Fireye before ordering.  
This High Energy Igniter is intended for intermittent operation as Class 3 Special igniter.  
The igniter is made of high quality materials, and its components are rigorously checked and tested prior to dispatch. No 
moving parts and parts requiring adjustment ensure long and trouble-free operation at low service costs.  
All of this makes 

HDHESI 

a reliable and effective source of direct ignition of gas burners and oil burners in heavy duty 

applications.  
Familiarization with the following instructions will reduce the possibility of equipment failure to a minimum and ensure 
safe operation.
