LT300 Igniters

Gas Air Mixer Assembly
The Gas is supplied to the mixer and is prevented from entering the Igniter by 2 off solenoid valves. At the same time the air is supplied via a filter and regulator mounted on the ignition plate. This air is prevented from entering the Igniter by a single solenoid valve. When a voltage is applied to the solenoids the valves are opened allowing the gas and the air flow through to the mixer. The gas and air is metered entering the mixing chamber to give the correct gas air ratio for ignition. The flame is lit by a high tension spark at the tip of the pilot.

LT300s Gas/Air Pre Mix Igniter
This Igniter, of the gas-air mix design, produces a very hard stable gas flame and will light the main fuel all conditions of combustion air flow. It is possible to totally discriminate between the Igniter gas flame, and the main flame by incorporating our gas flame ionisation detection system. The igniter uses a high tension spark to ignite the primary mixture supplied from the gas/air mix valve complex. The pulse coil is directly mounted on the non firing end of the Igniter. The central ignition rod is also used to provide the ionisation signal. One stainless steel flexible hose is connected from the ignition plate to the Igniter. The Igniter is then fitted in a fixed position with the firing end behind the air stabiliser of the burner.

LT300XL Gas/Air Pre Mix Igniter
This igniter comprises an internal pre-mix pilot as described above, with an additional neat gas annulus providing additional heat input for special applications where a larger ignition flame or pilot is required.
