Self-Aspirating Gas Fired Igniters

Self-aspirating gas fired igniters guarantee the reliable and safe ignition of main burners in furnaces and boilers if no air supply lines are available. SMITSVONK gas igniters can be equipped with one additional gas tube for increased heat release and flame stability.



Self-aspirating gas fired igniters guarantee the reliable and safe ignition of main burners in furnaces and boilers if no air supply lines are available. SMITSVONK gas igniters of size Ø38 mm can be equipped with one additional gas tube for increased heat release and flame stability.

The design is insensitive to moisture as the initial ignition is based on the proven high energy ignition technology of SMITSVONK. Integrated long-lasting spark plugs and ionisation electrodes assure a long service life with a minimum of downtime for maintenance.

The intake of combustion air is easily  adjusted at all models. If needed the conversion to a forced-air gas fired igniter is possible with little effort.
