To reduce the risk of excessive pressures in this
water heater, install pressure protective equipment
required by local codes and no less than a pressure
relief valve certified by a nationally recognized
testing laboratory that maintains periodic inspection
of production of listed equipment or materials.This
valve must be marked with a maximum set pressure
not to exceed the marked maximum working
pressure of the water heater. Install the valve into
an opening provided and marked for this purpose
in the water heater, and orient it or provide tubing
so that any discharge from the valve exits only
