Read and understand instruction
manual and safety messages
before installing, operating or
servicing this water heater.
Failure to follow instructions and
safety messages could result in
death or serious injury.
Instruction Manual must remain
with water heater.
Read this manual first. Then, before checking the water heater,
make sure the gas supply has been turned "OFF", and never
turn the gas "ON" before the tank is completely full of water.
Never use this water heater unless it is completely filled with
water. To prevent damage to the tank, the tank must be filled
with water. Water must flow from the hot water faucet before
turning "ON" gas to the water heater.
A,
Water at the draft hood is water vapor which has
condensed out of the combustion products. This is
caused by a problem in the vent. Contact a qualified
technician.
Leakage Checkpoints
B. *Condensation may be seen on pipes in humid weather or
pipe connections may be leaking.
C. *The anode rod fitting may be leaking.
AIR GAP
FIGURE 35.
D. Small amounts of water from temperature-pressure relief
valve may be due to thermal expansion or high water
pressure in your area.
E. *The temperature-pressure relief valve may be leaking at
the tank fitting.
F. Water from a drain valve may be due to the valve being
slightly opened.
G. *The drain valve may be leaking at the tank fitting.
H,
Combustion products contain water vapor which can
condense on the cooler surfaces of the tank. Droplets
form and drip onto the burner or run on the floor. This is
common at the time of start-up after installation and when
incoming water is cold.
Water in the water heater bottom or on the floor may be
from condensation, loose connections, or the relief valve.
DO NOT replace the water heater until a full inspection
of all possible water sources is made and necessary
corrective steps taken.
Leakage from other appliances, water lines, or ground
seepage should also be checked.
To check where threaded portion enters tank, insert cotton
swab between jacket opening and fitting. If cotton is wet,
follow draining instructions in the "Draining" section and then
remove fitting. Put pipe dope or teflon tape on the threads
and replace. When you are finished, follow the steps in
"Filling the Water Heater" in the Installation Instructions
earlier in this manual.
