TROUBLESHOOTING
ODS pilot lights but pilot flame goes
out before burner lights.
1. Gas shutoff valve not fully open.
2. Missing or weak batteries at power sup-
ply box or remote.
3. Thermocouple circuit between the ODS
pilot and control module is loose or
damaged.
4. Pilot flame is not touching thermocou-
ple.
5. Thermocouple damaged.
6. Control valve damaged.
1. Fully open gas shutoff valve.
2. Replace batteries.
3. Check thermocouple terminal con-
nection at the control module.
4. Clean ODS pilot with canned air or
call service technician.
5. Replace ODS pilot assembly.
6. Replace control valve.
Burner system lights from the remote
but not from the switch.
1. Switch cable disconnected or broken.
2. Connect or replace the switch or
cable.
Produces unwanted odors
1. Heater burning vapors from paint, hair
spray, glues, cleaners, chemicals, new
carpet, etc.
2. Low fuel supply (LP only).
3. Gas Leak (see warning on front page).
1. Open window to ventilate room.
Stop using odor causing products
while gas logs are running.
2. Call LP gas company.
3. Turn off gas. (see warning on front
page).
Log set cycles to pilot, but room tem-
perature drops to a lower than ideal
level before log set comes back on.
1. Thermostat remote control is too close
to heater.
2. Air in the gas line.
3. Dirty or partially clogged burner
orifice.
4. Bad burner orifice.
1. Move hand-held remote control
farther away from heater.
2. Operate burner until air is removed
from the gas line. Have gas line
checked by local gas company.
3. Clean burner or replace burner
orifice.
4. Replace burner orifice.
Delayed ignition of burner.
1. Manifold pressure is too low or pilot
and or burner need cleaning.
1. Contact service technician.
Either the remote or switch are
pressed to start the burner ignition
sequence and there is no function or
response.
1. Missing or weak batteries at power
supply box or remote.
2. Box is unplugged.
3. The switch cable is not plugged into the
module.
4. Control valve wiring harness not
plugged in or not in proper position.
5. Remote not communicating with the
control module.
6. Igniter cable is not connected.
7. Broken igniter cable
8. Igniter electrode positioned wrong.
9. Igniter electrode is broken.
1. Check batteries and replace if need-
ed. Set the multimeter to DC volt-
age, initiate the ignition sequence
and observe the voltage while the
system is lighting (under load). The
system will not function under 3.8
volts and batteries should be re-
placed if the voltage is under 40
volts.
2. Plug battery box into module.
3. Plug switch cable into module.
4. Check to see that the control valve
wiring harness (blue connector) is
plugged into the module correctly.
5. Remote may need to go through the
“Learn” process with the module.
6. Check the igniter connection at both
the control module and the ODS
pilot.
7. Replace igniter cable.
8. Replace ODS pilot assembly.
9. Replace ODS pilot assembly.
Burner will not light after ODS/pilot
is lit.
1. Inlet gas pressure too low.
1. Call for service.
