1. Product Information
The Inline Pilot (ILP) is a unique pilot design that uses a single internal, inline ignitor and flame detection rod fitted
into a specially designed combustion nozzle. The nozzle consists of an optimized internal diffuser and welded shell
assembly. The assembly is connected to a base hub through a cylindrical spacer tube. This spacer tube comes in
several length options. The base hub accommodates the upstream mixer and inline flame rod base connection via
two threaded input ports.
One of the key features of the ILP is the use of Profire’s patented Near Field Ionization (NFI) technology. Profire
utilizes a unique diffuser design which orients the flame to flow past the internal flame detection rod resulting in
superior flame detection via ionization.
Features
The PROFIRE Inline Pilot is designed for the following:
1. Reliable lighting even in extreme environmental conditions.
2. Continues to function below the normal operating inlet gas pressure, even in adverse conditions.
3. Simple installation.
4. Reliable flame anchoring and detection using NFI with no rod adjustment needed.
5. One easily removable, internal ignition and flame detection rod fitted inside a custom combustion nozzle.
6. Automatically aspirates air into the mixture to make up any deficits for maintaining a sustained flame.

2. Installation
The following steps provide instructions to complete the installation process. Please read the entire section and
follow the instructions carefully.
Important Safety Information
Fire or Explosion Hazard. Failure to properly ground the ILP back to the Burner Management System’s Ion terminal
may result in accidental electrocution, product damage, or failure to ignite the pilot.
Check the maximum temperature for your installation and use suitable wiring for that application.
Connect the System
Connect the appropriate wires to the BMS terminals as described. Connect the gas line adapter fitting and gas line
to the source.
Please note: The Inline Pilot MUST be grounded to a suitable ground via the included grounding screw (green
screw) located on the rear of the Inline Pilot base hub.

Operation Tips
For typical installations, use the provided #66 orifice. A #60 or #72 orifice can be used with the ILP for specific
installations. See the troubleshooting section for more details.
It is recommended that an Inline Gas Filter be used with the ILP to prevent the orifice from clogging due to any
gas impurities.
The best operating pressure range is 3-5 psi. The optimal operating pressure can vary with orifice size and gas
quality.
Test the Hardware (Optional)
It is recommended that you test electrical connections and the system before mounting the ILP.
Gasless Test
1. After grounding the ILP, use the BMS system to start the ignition sequence.
2. Press the Ignite button to initiate sparking.
3. Listen or carefully look for a spark inside the nozzle.
WARNING: Do not connect the ILP to the gas line for this test. Gas MUST be off. Make sure that the ILP is
grounded properly.

Gas Test
1. Connect the ILP to the gas line.
2. Press the Ignite button to initiate sparking.
3. The ILP will spark and ignite the gas flowing up to the nozzle.
4. As soon as there is flame, the sparking will stop and the BMS will switch to flame detection.
Please note: The flame is very efficient and may be difficult to see in daylight or direct light. Check that the
Flame LED on the BMS is on.
Once you have successfully completed the system tests, turn off the flame and proceed with installing the
system in your application.
Please note: Testing with a gas other than the process fuel may have different results.
3. Install the System
Secure the ILP to the burner using clamps that fit your specific installation and the provided struts. Assemble the
hardware as shown in the following diagram:

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.
4. 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.

THE ILP is sparking, but not at the nozzle:
This is possibly an ignition rod failure. Replace the rod by unscrewing the rod from the base of the ILP and
replacing it with a new rod.

It has been determined that the ILP nozzle and/or the ignition rod need to be replaced:
•Unscrew the nozzle or ignition rod and re-insert replacement components.
•Use a high temperature anti-seize compound sparingly on the threads. Approved anti-seize compounds
include silver and copper-based products rated at 1600°F (871°C) or above. Avoid over application of
anti-seize product.
Previous process pilot required a higher psi to keep the supply line from freezing:
It is not necessary to operate at pressures above 6 psi with this pilot as it will still function below the normal
operating range, even in adverse conditions.
