DESCRIPTION
The Surefire II High-Energy Ignition System is used for direct spark ignition of most gas or liquid
fuels used in oil or gas igniters or main burners. The High-Energy Ignition System is available in
various versions. To ensure optimal operation, the first part of the ignition tip should always be in an
ignitable fuel-air mixture, during all modes of operation.
After successful ignition, the ignition tip should be disconnected from the power supply and taken
out of the flame. Optionally, when an automated process is required, a pneumatic retraction unit and
systems for hazardous areas are available.
The Surefire II range includes:
Integrated power pack with spark rod.
Split Power pack and separate spark rod.
Portable battery powered Integrated power pack and spark rod.
ATEX, Power pack, and spark rods.
Co-axial Retractors, with / without integrated solenoid valve.
ATEX Solenoid.
Features
Selectable voltage ( 115/230 vac ).
Visual indication of spark operation
Proof of spark relay
Choice of system, Integrated or Kit or Kit with Quick Disconnect
Thermal cutout protection integrated in transformer
ATEX options
Compact "co-axial" retractors

High Energy Igniters DESCRIPTION The Surefire II High-Energy Ignition System is used for direct spark ignition of most gas or liquid fuels used in oil or gas igniters or main burners.

Page 2: Typical Applications
APPLICATIONS High Energy Spark Igniters ( HESI ) are well suited to ignite most gaseous and liquid fuels, either by first igniting a pilot or directly igniting the main burner. The HESI is classified as being a class 3 special igniter (NFPA regulations). Burner designers should ensure the correct position of the igniter tip, and the maximum capacity of flame to be ignited to ensure compliance with prevailing regulations. -

Page 4: Safety Instructions And Precautions
Safety instructions and precautions Safe use and operation: Improper handling can result in significant personal injuries and damage to property. Only an appropriately qualified operator or electrician should perform work on this high-energy igni- tion system. Operator is a person who is responsible for installing, operating, adjusting, maintaining, cleaning, repairing or transport of equipment, so that possible dangers can be recognized and avoided. -

Switching on the power will immediately generate 4-5 ignition sparks per second. The transition of the ignition spark can be seen through the built-in inspection window.

- Page 9 Assembly: The kit, consisting of the individual parts above, will make an igniter 1m long, and must be assembled by the user. The advantage is the reduced packed size, and resulting low shipping costs. Start the assembling with the ignition rod. The length of the ignition electrode, including the ignition tip, starts at 1m up to a maximum of 3 m The complete length of the igniter is adjustable by addition of stainless steel extension tubes, each with male and female threading, in increments of 0.5 m and 1m.

Page 14: Operation
Operation With the High-Energy Ignition System Surefire II, the ignition sparks are turned on or off by applying or removing the power supply. After starting the ignition and subsequent positioning of the ignition electrode tip (see image below), the ignition spark must be exposed to an ignitable fuel-air mix. - Page 15 Please follow the instructions on page 15 and observe the general safety instructions on page 4 before you open one unit. Fireye recommends the following spare parts: HE-CRD: Exchangeable full completed printed circuit board to be used in Power Pack for all versions (except...

Page 16: Maintenance
Maintenance Please carefully read the safety instructions on page 4 before undertaking any maintenance work. In principle, the high-energy ignition system is maintenance-free, but inspections should be carried out at regular intervals to check for dirt and structural integrity (e.g. possible damage to the metal protection sleeve). - Page 17 A standard power pack circuit board is fitted into the ATEX enclosure. This enclosure also has pro- vision for mounting a Fireye MBCE, Flame rod ( Ionization rod) amplifier. This should be defined at the point of order and is priced according to the standard Fireye price list.

Page 18: Retraction Systems
Retraction systems The Surefire retraction system uses a "co-axial" mounting of the HESI rod to provide a compact fixing arrangement. The standard retractors are available in 6", 9", 12", and 18" retraction lengths, all of which are pneumatically operated from a nominal 6Barg. ( maximum 10Barg, minimum 3Barg ) pressure line. - Page 19 B=648mm C=100mm D=1175mm INSTALLATION. There are 4 available methods of installation recommended by Fireye. RET FB2 The first utilizes angled brackets shown on right. These brackets are mounted onto the front and/or rear of the cylinder, and then mounted onto support steel work of the customer supply.
- Page 20 It can be seen from the diagram that the 2 critical measurements are B and D, these are fixed for each stroke length. The fourth shows the second of the Fireye distance pieces, shown below This consists of a flange, attached to short length of pipe, with a 1"...
- Page 21 Both of the above arrangements have allowed a 100mm distance between the end of the cylinder and the burner or boiler front. This distance is fixed for Figure 14/2, using the Fireye mounting piece, but can be site set if required for Figure 14/1 above. The mount tube in the burner is customer supply only, and generally requires to be 1 inch nominal bore, or bigger.
- Page 22 FIGURE 13. Attaching the HESI to the retractor. The mounting rings come as a pair. One ring (A), will fit on the retractor tube, the other (B), will fit on the HESI rod (P/N “RET CLMP”). The ring for the retractor rod is fitted first, allowing a small overhang beyond the end of the retractor rod of no more than 1mm.
- Page 23 give the required return speed. The two valves should then be finely adjusted to give the correct speeds in each direction. It should be noted that the two valves have to be adjusted together as their actions are related one to the other. Having achieved the correct stroke speed, the 2 cushion valves are adjusted to give an acceptable de-acceleration at each end of the travel.
