• Verify all connections between the wire harnesses and the
system components are proper and positive.
• Verify the communication link is established between the
remote control and the IFC module.
• Verify inlet pressure meets the recommended inlet pressure.
If necessary, adjust line pressure regulator.
Restore electrical power to appliance or use battery back-up.
Ensure batteries are fully charged if using battery back-up as
power source.
Use wiring schematic (See Figure 10.1 on page 23) to determine
that all wiring connections are secure and correct.
Check remote shut-off valves from the appliance. Usually there is
a valve near the main gas line. There may be more than (1) valve
between the appliance and main gas line.
Check LP (propane tank). Refill if necessary.
Consult a plumber or a gas supplier.
Can be caused by situations such as a bent line, too narrow
diameter or pipe, or a low line pressure.
Verify the pilot flame envelopes the top of the flame sensor and
extends far enough onto burner for ignition.
To adjust pilot flame, turn pilot adjustment screw on the gas valve
clockwise to decrease flame, and counterclockwise to increase
flame.
Seal pilot adjustment screw. Do not over-tighten.
Set control system to IPI mode (See Section 11.8.3 on page 27).
Switch rocker switch to ON position.
Check for multiple shut-offs in the supply line. Verify gas supply is
turned on.
Consult with plumber or gas supplier.
Check LP (propane) tank. Refill if necessary.
Check for faulty or incorrect wiring.
Remove blockage.
Verify the pilot flame is properly directed to ignite burner. See pilot
flame troubleshooting above.
Replace batteries.
Verify remote control is powered ON and thermostat operation is
turned OFF.
