if excessive, can drip into the floor shield. Also, during
normal operation there may be occasions when large
quantities of water are drawn, chilling the tank bottom. This
too can result in condensation.
• Condensation, appearing in the vent pipe (water dripping
from draft diverter) during heater operation is evidence of
poor vent action. Possible causes are too long a vent pipe
or improper chimney operation.
3. If the leakage is from the temperature and pressure relief valve
or its discharge pipe, it may represent a normal condition.
However, see RELIEF VALVE section on page 14. DO NOT
PLUG THE TEMPERATURE AND PRESSURE RELIEF VALVE.
Also, the leakage could be due to unusually high water
pressures or temperatures in the system, or to a faulty relief
valve. Your dealer or a qualified service technician should be
called to determine the cause of the problem and to correct it.
4. If you cannot identify or correct the source of water leakage:
• Close the main shutoff valve in the gas supply pipe at the
heater. See fig. 4, page 7.
• Close the valve which feeds water to the cold water inlet at
the top of the heater.
• Contact your dealer.
WATER HEATER MAKES SOUNDS
1. Occasional excessive condensation, as explained under
WATER LEAKAGE IS SUSPECTED, can cause a sizzling sound
as the moisture is vaporized by the gas flame. This is a normal
sound and may be disregarded.
2. Sediment and water scale accumulations may cause rumbling
noises. See PREVENTIVE MAINTENANCE or contact your
dealer for details of flushing the heater.
3. If you cannot identify or remedy the condition, contact your
dealer.
