If local codes require external application of insulation blanket kits the manufacturer’s instructions included with the kit must be carefully
followed.
In addition, pay careful attention to the following so as not to restrict the proper function and operation of the water heater:

Do not cover the operating or warning labels attached to the water heater or attempt to relocate them on the exterior of the
insulation blanket.

Do not apply insulation to the top of the water heater. This could interfere with the safe operation of the electrical junction box.

Do not cover the jacket access panel(s) to the thermostat(s) and heating element(s), or temperature and pressure relief valve.

Inspect the insulation blanket frequently.
Failure to follow these instructions could result in substantial property damage, severe personal injury, or death.
E. TEMPERATURE AND PRESSURE RELIEF VALVE
NOTE: For protection against excessive pressures and temperatures in this water heater, install temperature and pressure protective
equipment as required by local codes, but not less than a combination T&P valve meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22B / CSA 4.4-M99 , by a nationally recognized testing
laboratory that maintains periodic inspection of production of listed equipment and 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 T&P valve into the opening
provided and marked for this purpose on the water heater so that discharge water from the valve will not come in contact with any live
electrical parts.
To avoid water damage or scalding due to relief valve operation:

Discharge line must be connected to relief valve outlet and run to a safe place of disposal. Terminate the discharge line in a
manner that will prevent possibility of severe burns or property damage should the relief valve discharge.

Discharge line must be as short as possible and the same size as the valve discharge connection throughout its entire length.

Discharge line must pitch downward from the valve and ter
minate at least 6” above the floor drain, making discharge clearly
visible.

The discharge line shall terminate plain, not threaded, with a material serviceable for temperatures of 375
o
F or greater.

Do not pipe discharge to any location where freezing could occur.

No shutoff valve may be installed between the relief valve and heater or in the discharge line. Do not plug or place any
obstruction in the discharge line.

Test the operation of the relief valve after filling and pressurizing the system by lifting the lever. Make sure the valve
discharges freely. If the valve fails to operate correctly, immediately replace with a new properly rated relief valve.

Test T&P valve at least once annually to ensure the waterway is clear. If valve does not operate, turn th
e heater “off”
and call
a plumber immediately.

Take care whenever operating relief valve to avoid scalding injury or property damage.
FAILURE TO COMPLY WITH THE ABOVE GUIDELINES COULD RESULT IN FAILURE OF RELIEF VALVE OPERATION,
RESULTING IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.
Do not thread a cap or plug into the relief valve under any circumstances! Explosion and property damage, serious injury, or death may
result.
F. FILLING THE HEATER
When filling the water heater, open a hot water tap to release air in the tank and piping. The tank must be full of water before the heater
is turned on. Failure to ensure the water heater is full before turning it on will result in damage to the water heater, and could result in
property damage, serious personal injury, or death. Such damages ARE NOT covered by water heater warranty.
