to module securely. (See Fig. 1)
• 8-Pin Connector – orange/white wires to Pilot on valve
and green/white wires to Main on valve. Black wire (ground) to valve; Grounding is critical for
proper operation. (See Fig. 2)
Sensor Safety – 4 beeps every second / constant beeping
Sensor detects a flame, but flame is not present. Will also occur if flame (S) sensor wire is shorted to ground.
Check
• Pilot flame is actually present when valve is turned OFF
(valve replacement necessary if yes).
• Flame sensor electrode is not touching burner pan, log
grate or pilot hood assembly.
• Flame sensor wiring is not worn, frayed, pinched or
damaged.
• Disconnect “S” wire from module and press “ON” on
transmitter.
• Is there a ticking sound at module? If Yes, module is
working as designed, check pilot assembly.
Check Pilot Assembly
• Pilot wires – “I“ (Ignitor) and “S” (Sensor) wires connected to module securely. (See Fig. 1)
• 8-Pin – black (ground lead) to valve. (See Fig. 2)
• No splices to wires, cuts, crimps; these can cause shorts.
• Check spark gap at pilot assembly. Gap should be 3mm (1/8”) from hood to 1
st
spark electrode. Too close
will not spark, too far it will spark to the burner pan or log grate.
• Check the (white) ceramic insulators to make sure that there are no cracks at each spark electrode, if cracked,
replace pilot assembly.
• If No ticking sound, check battery voltage. Battery voltage should be a minimum of 5.3 volts DC in the
battery pack or if using a AF-4000ADP24 DC Adapter, a minimum 6.75 to maximum 8.25 volts DC. If
proper voltage is obtained, module needs to be replaced.
Thermal Safety – 4 beeps every 2 seconds
Overheating – Internal module temperature exceeds 170 degrees F.
Check
• Control module must stay inside the valve box. Never move outside or other locations.
• If valve box is too close to burner, move to cooler location.
• If glass doors are installed they need to be fully opened during operation.
Other Symptoms
Burner Flame Will Not Modulate Or Works Backwards
Check
• Battery voltage should be a minimum of 5.3 volts DC in the battery pack and a minimum of 9.0 volts DC in
the transmitter.
• Red indicator light on transmitter illuminates when buttons are pressed.
• 4-pin connector from module to battery pack is secure.
