The tip is typically mounted onto a 1/8” Sch 40 304 SS pipe or 3/8” 0.035” 316 SS tubing and via an adapter
inserted into or adjacent to the pilot mixing tube. The ignition wire passes down through the pipe/tube
which provides mechanical protection and a return path for the igniter current.
The ignition cable must be rated for a minimum 600VAC and 90C and be #14 or #12 multi-strand copper
wire. Connect the high voltage wire to the “IGN” terminal on the “eHEnergizer”.
A ground wire is prewired in pre-assembled enclosures from the enclosure body to the “eHEnergizer” high
voltage “G” terminal. This will provide a common ground path from the pipe/tube to the “eHEnergizer”.
The resistance of the ground path has to be less than 0.2Ω between the outside shell of the igniter tip
and the high side “G” terminal of the “eHEnergizer”.
If using a direct mount assembly, ensure the SST pipe/tube is properly fastened to the adaptor and
enclosure without use of Teflon tape or sealing compound that would impede the ground path.

Remote Field Wiring
The “eHEnergizer” may be remote mounted a significant distance from the igniter tip. This may be
necessary, for example, when mounting in a panel that is located outside of a hazardous area.
The recommended maximum distance for remote mounting of the “eHEnergizer” is 1000ft i.e. the
ignition wire should not exceed 1000ft in length. If the installation requirement cannot satisfy this
please contact Unifire to understand how longer distances can be accommodated.
