Installation Tips
Horizontal Applications
Install the ILP parallel to the primary burner and align the etch line on the pilot nozzle with the first point of gas
contact on the main burner nozzle. (See diagram above for details).
Vertical Applications
Install the ILP vertically and align the etch line on the pilot nozzle with the first point of gas contact on the main
burner nozzle. (See diagram above for details).
General
Avoid direct flame impingement from the primary burner on the nozzle. Direct flame impingement on the Inline
Pilot tube body behind the pilot nozzle may result in the loss of flame and will decrease the lifespan of the
product.

Troubleshooting
Inline Pilot will not light:
•
Turn the gas off and make sure the ILP is grounded properly. During the lighting sequence, confirm that
there is a spark inside the nozzle.
•
Check for gas pressure to the orifice.
•
Verify that the orifice is free of obstructions.
The BMS is not detecting flame from the ILP:
•
Make sure the spark wire is properly insulated.
•
Check that the length of the spark wire is less than 30 ft (9 m) with flame detect set to ionization.
The BMS is not detecting any flame and the ILP is lit but the flame quality is poor:
Check the size of the orifice; a smaller orifice (e.g. - #72) is recommended for propane while a larger orifice (e.g.
- #66 to #60) is recommended for natural gas. The ILP has been optimized at these small orifice sizes as an orifice
as large as 1/16” will yield poor flame quality.
