High Energy Spark Igniter rod should be fitted such that the tip end should be placed at a distance of ~50 mm
back from the stabilizer plate. High Tension Igniter should be placed closer to the stabilizer plate, at a distance of
~10 mm.
It should be noted that the rod tip positioning against the stabilizer plate in the pilot gas part assembly (pos. 1
on Fig. 1) should be done outside the air tube only (do not install the rod in the gas head already mounted in
the air tube). Only after proper rod positioning, should the rod be fixed by tightening the rod holding gland
and the whole gas assembly with igniter rod inserted into the air tube pos. 4.
The rods of both types of devices are held in the gas head by means of a fixing gland 1/2"BSP.
The ignition device is not in gas pilot scope of supply. It is normally specified and ordered separately.

6. OPERATIONAL SAFETY
When operating and handling the pilot burner please follow the rules below:
6.1
Use pilot only for its intended purpose.
6.2
At the time of installation, operation and maintenance follow the procedures described in the instructions
and documentation of the pilot, ignition device and the main burner.
6.3
Check environmental conditions and ensure that the specified operating temperatures of pilot
and igniter components will not be exceeded
(
see p. 5 and igniter Manual).
6.4
Follow the warnings contained in the documentation.
6.5
Do not make any modifications or changes to the pilot construction.
6.6
Before starting, make sure that all parts of the pilot and electric ignition device are in good condition.
6.7
Circuits of power packs as well as igniter enclosures and junction boxes must be properly grounded.
6.8
Before igniting, check the tightness of gas tube connections.
6.9
During the observation of the pilot flame wear special goggles to protect the eyes from UV flame radiation.
6.10
Do not remove the protective ground when the ignition device is energized.
6.11
Before working on the ignition device, make sure that power is disconnected.
6.12
Before maintenance or repair works check if the gas shut-off valve is closed.
6.13
During installation, start-up or maintenance works on the pilot or burner/heater always wear protective
clothing and use protective gloves
.
