Pilot ignition
The standard Vortometric spark-ignition pilot requires an ignition
transformer with a minimum of 6000 volt secondary. Mount the
transformer in a location where it will not overheat while allowing
as short an ignition lead as possible.
Pilot assembly positioning
The relation of the pilot assembly to the main burner gun affects air
flow through the throat cone. Therefore, it is important that the pilot
be as far away as possible from the throat cone while maintaining
reliable ignition. For initial start-up, the pilot assembly should be
between 6" and 8" away from throat cone; if necessary, adjust the
pilot assembly gland to achieve this distance.
Support the piping and ductwork
Use brackets or hangers to support the piping and ductwork to
avoid placing undue loads on the burner. If you have questions,
consult your local gas company.
Pipe connections
The use of flexible pipe in gas, oil and atomizing air lines to the
burner is recommended. Adjustments of the main gas, pilot gas and
oil guns may be required during burner setup.
Avoid large pressure drops
Note:
The pressure drop of the gas in the piping is a critical
parameter. Make sure that the size of all the piping is large
enough to prevent excessive pressure losses.
