Installation (Water Connections) continued-
The water heater and individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of the
system at test pressures in excess of 1/2 psi (3.5 kPa). The water
heater must be isolated from the gas supply piping system by closing its
manual shutoff valve during any pressure testing of the gas supply
system at test pressures equal to or less than 1/2 psi (3.5 kPa). The
supply line must be capped when not connected to the water heater.
3. While checking for leaks care must be taken to prevent solution from
contacting the electrical connections at the control. If electrical
connections at the control become wet, they must be thoroughly dried
before attempting to operate the water heater.
The gas inlet pressure to the gas control must never exceed 14
inches of water column (1/2 psi). The gas supply system and any
pressure regulating device in the gas line must be specified,
inspected and adjusted to assure a gas supply pressure of 1/2 psi
or less. Failure to do so may result in severe injury or death.
