SECTION V
WATER CONNECTIONS
WARNING
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED
TEMPERATURE AND PRESSURE RELIEF VALVE WILL
RELEASE THE MANUFACTURER FROM ANY CLAIM WHICH
MIGHT RESULT FROM EXCESSIVE TEMPERATURE AND
PRESSURES.
Hydrogen gas can be produced in an operating water heater that
has not had water drawn from the tank for a long period of time.
HYDROGEN GAS IS EXTREMELY FLAMMABLE. To prevent
the possibility of injury under these conditions, we recommend the
hot water faucet be opened for several minutes at the kitchen sink
before you use any electrical appliance that is connected to the
hot water system. If hydrogen is present, there will be an unusual
sound such as air escaping through the pipes as hot water begins
to flow. DO NOT smoke or have open flame near the faucet at the
time it is open.
Keep clear of the temperature and pressure relief valve discharge
line outlet. The discharge may be hot enough to cause scald
injury. The water is under pressure and may splash.
CAUTION
If sweat fittings are to be used, DO NOT apply heat to the nipples
on top of the water heater. Sweat the tubing to the adapter before
fitting the adapter to the water connections. It is imperative that
heat is not applied to the nipples containing a plastic liner.
