Remedy
05
Imperfect Combustion Alarm
Clean air inlet fi lter.
Clean combustion air fan.
Clean heat exchanger fi ns.
Check for adequate combustion air ventilation openings and clean if neces-
sary.
Check vent system for partial blockage and correct as necessary.
10
Decrease of Fan Motor Ventilation
Amount
Air Supply or Exhaust Blockage
(Warning)
Check all vent components for proper connections.
Check that nothing is blocking the fl ue inlet or exhaust.
Ensure condensation trap/drain was installed correctly.
Ensure heat exchanger fi ns, fan, and air intake are not blocked.
11
Ignition Failure
No Ignition
Ensure you have gas to the appliance and valves are turned ON.
Ensure gas type and pressure is correct.
Bleed all air from gas lines.
Ensure gas line, meter, and regulator are sized properly.
Ensure appliance is properly grounded.
Check gas solenoid valves for open or short circuits.
Ensure igniter is operational.
Check igniter wiring harness for damage.
Ensure maximum vertical vent length does not exceed allowable limits.
Ensure total maximum vent length does not exceed allowable limits.
12
Flame Failure
Ensure you have gas to the appliance.
Ensure gas type and pressure is correct.
Bleed all air from gas lines.
Ensure fl ame rod wire is connected.
Check fl ame rod for carbon build-up.
Ensure gas line, meter, and regulator are sized properly.
Ensure appliance is properly grounded.
Check gas solenoid valves for open or short circuits.

13
Oxygen Depletion Sensor (O.D.S.)
Working (Poor or Improper Com-
bustion)
Ensure there is plenty of fresh air to the unit.
Unit needs 1 square inch (6.5 cm2) for each 1,000 BTU of input.
Check for a foreign materials in combustion chamber and/or O.D.S. De-
vice.
14
Over Heating
Ensure high fi re and low fi re manifold pressure is correct.
Check gas type of unit and ensure it matches gas type being used.
Check heat exchanger for cracks and/or separations.
Check for restrictions in airfl ow around unit and vent terminal.
Check for a foreign materials in combustion chamber and/or exhaust pip-
ing.
Check for clogged heat exchanger (scale buildup).
