- Probable Cause
- Control Status
- LED Status
- Millivolt power is not present. Light pilot.
- None (LED not on or flashing)
- Gas valve is powered and waiting for the set point knob to be turned to a water temperature setting. If the set point knob is at desired setting the thermostat is satisfied.
- If set point knob is in “PILOT” position, then pilot flame is detected. (no faults).
- One flash and three second pause
- LED strobe (two quick flashes) and three second pause
- Water heater operating normally.
- Thermostat calling for heat (no faults).
- Set point knob was recently turn to “OFF” position. Wait until LED goes out before attempting to relight.
- Set point knob has been recently turned to the “OFF” position.
- LED on continuously
- Weak pilot flame detected. System will reset when pilot flame is sufficient.
- Two flashes and three second pause
- Insufficient water heating. System will reset.
- Three flashes and three second pause
- Excessive tank temperature. System must be reset.
- Four flashes and three second pause

Maintenance continued-
6. At least once a year, check the combination temperature and pressure relief valve
to ensure that the valve has not become encrusted with lime. Lift the lever at the
top of the valve several times until the valve seats properly without leaking and
operates freely.
7. Monthly drain off a gallon of water to remove silt and sediment.
8. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed water
supply system. Contact the water supplier or local plumbing inspector on how to
correct this situation. DO NOT plug the combination temperature and pressure
relief valve outlet.
9. A combination sacrificial anode rod/hot water outlet nipple has been installed to
extend tank life. The anode rod should be inspected periodically (every 2 years)
and replaced when necessary to prolong tank life. Water conditions in your area
will influence the time interval for inspection and replacement of the anode rod.
Contact the plumbing professional who installed the water heater, or the
manufacturer listed on the rating plate for anode replacement information. The use
of a water softener may increase the speed of anode consumption. More frequent
inspection of the anode is needed when using softened (or phosphate treated)
water.
10. The vent system must be inspected at least once a year to ensure against leakage
of exhaust products.
WARNING
• DO NOT operate water heater with jumpered, altered, loosely tightened or
absent controls and/or components.
• DO NOT operate water heater with replacement controls and/or components,
which are not exact duplicates or original equipment.
• Thoroughly inspect and replace, (as needed) burner inner door gasket and/or
sight window gasket any time burner inner door is removed or disturbed.
• Replace water heater if involved in flammable vapors incident.
WARNING
When lifting lever of the combination temperature and pressure relief valve, hot
water will be released under pressure. Be careful that any released water does
not result in bodily injury or property damage.
WARNING
DO NOT run out of propane gas. Damage to the water heater may occur.
WARNING
THIS WATER MAY BE HOT.
