TROUBLESHOOTING GUIDE
CONDITION CAUSE REMEDY
Slow hot water recovery.
Insufficient secondary air. Provide fresh air ventilation.
Low gas pressure. Check with gas utility company.
Gas control valve set too low. Turn temperature dial to desired temperature.
Improper calibration. Replace gas control valve.
Flue clogged. Clean. Check for source of trouble and correct.
Water heater is undersized. Install size of water heater that meets demand.
Wrong piping connection. Correct piping, dip tube must be in cold inlet.
Wasted hot water. Advise consumer.
Leaking water.
Poorly sealed, hot or cold water connec-
tions, gas control valve threads, relief
valve or drain valve.
Tighten threaded connections.
Leakage from plumbing system or other
appliances.
Inspect plumbing system and other appliances.
Condensation. Refer to
Condensation .
Water drips from the relief
valve.
Heater stacking. Lower gas control valve setting.
Excessive water pressure. Install a pressure-reducing valve.
Thermal expansion in a closed water sys-
tem.
Install an expansion tank.
Improperly seated valve. Check relief valve works properly and replace, if neces-
sary.
The gas control valve fails
to shut-off.
Defective gas control valve. Replace with new gas control valve.
Improper calibration. Replace gas control valve.

vided in this manual.
Ambiant air temperature is too high. Reduce ambiant air temperature.
Excessive dirt, dust or other debris accu-
mulation on the flame arrestor.
Clean the flame arrestor in the combustion chamber using
a stiff brush, compressed air and/or a vacuum cleaner.
