When strapping a gas water heater, the lower seismic strap must be located:
a.directly over the gas control valve
b.at the very bottom of the tank base
c.anywhere below the midpoint
d.at least 4 inches above the controls

The lower strap must be positioned no lower than 4 inches above the gas controls so the strap does not interfere with or damage the control valve. The upper strap goes in the upper third of the tank. Both straps anchor the tank to the wall framing.
