3.6 TROUBLESHOOTING
With proper installation and maintenance, your new Gas Heater should provide years of trouble-free service. If you do
experience a problem, refer to the Trouble Shooting Guide below. This guide will assist a qualified service person in
the diagnosis of problems and the corrective action to be taken.
Electronic Ignition System
Symptom Possible Causes Corrective Actions
1. No transmission, motor does
not turn.
a. Receiver must learn new
code.
Press and hold the receiver’s reset button until you hear 2
acoustic signals. After the second longer acoustic signal,
release the reset button and within the subsequent 20
seconds, press the down arrow on the remote handset until
you hear an additional long acoustic signal confirming the
new code is set.
2. No ignition. No tone. a. Receiver Replace receiver and reprogram code.
3. No ignition; one 5 seconds
continuous tone (7 shorts
beeps might be heard prior to
the 5 seconds tone).
a. ON/OFF switch is in OFF
position.
Push switch to ON position.
b. Loose wire. Secure wire.
c. Receiver. Replace receiver and reprogram.
d. Bent pins on 8 wire
connector.
Straighten pins on 8 wire connector.
e. Valve. Replace valve.
4. No pilot flame and control
continues to spark.
a. Air in the pilot supply line. Purge the line or start ignition several times.
b. Thermocouple circuit wired
incorrectly.
Check polarity of the thermocouple wires.
c. No spark at pilot burner Check spark gap, check wiring connection. Check for spark
in location along cable.
d. Valve. Replace valve. Do not over tighten.
e. Over tightened
thermocouple interrupter.
Replace valve and thermocouple interrupter.
f. Receiver. Replace receiver and reprogram code.
5. Pilot is lit and control
continues to spark. Valve shuts
off after 10 to30 seconds.
Valve operates manually.
a. Receiver. Replace receiver and reprogram code.
6. Pilot is lit, sparking stops if
a flame is present. Valve shuts
off after 10 to 60 seconds.
Valve does not work manually.
a. Thermocouple. Replace thermocouple.
b. Low inlet pressure to valve. Confirm sufficient inlet pressure to the valve. Adjust or
replace inlet regulator if necessary.
c. Valve. Replace valve and the thermocouple interrupter.
7. 3 short beeps while the
motor turns.
a. Batteries are low. Replace batteries - quality alkaline recommended.
WARNING: Creating an electrical short between the
batteries/battery box and metal parts of the appliance may
render the receiver inoperable.
8. Pilot flame lights but there is
no main gas flow.
a. Manual override know (if
equipped) is in MAN
position.
Turn Manual override know to ON position.
b. Valve turned don to pilot
flow.
Turn flame to high fire by pressing up button on remote
handset.
c. Low inlet pressure to valve. Confirm sufficient inlet pressure to the valve. Adjust or
replace inlet regulator if necessary.
9. Pilot sparks, but pilot will not
light.
a. Correct gas supply. Verify that incoming gas line ball valve is “open”. Verify that
inlet pressure reading is within acceptable limits, inlet
pressure must not exceed 50 mbar.
b. Ignitor gap is too large. Verify that spark gap from ignitor to pilot hood is .43 cm.
c. Module is not grounded. Verify module is securely grounded to metal chassis of
fireplace.
