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.
