WARNING
For protection against excessive temperatures and pressure, install
temperature and pressure protective equipment required by local codes, but
not less than a combination temperature and pressure relief valve certified by
a nationally recognized testing laboratory that maintains periodic inspection
of production of listed equipment or materials as meeting the requirements of
the Standard for
Relief Valves and Automatic Gas Shutoff Devices for Hot
Water Supply Systems, ANS Z21.22 or the Standard CAN1-4.4.
Temperature and Pressure
and the Standard
CAN1-4.4, Temperature,
Pressure, Temperature and Pressure Relief Valves and Vacuum Relief
Valves
. The combination temperature and pressure relief valve must be
marked with a maximum set pressure not to exceed the maximum working
pressure of the water heater. The combination temperature and pressure
relief valve must also have an hourly rated temperature steam BTU
discharge capacity not less than the hourly rating of the water heater.
Install the combination temperature and pressure relief valve into the
opening provided and marked for this purpose on the water heater.
Note: Some models may already be equipped or supplied with a combination
temperature and pressure relief valve. Verify that the combination
temperature and pressure relief valve complies with local codes. If the
combination temperature and pressure relief valve does not comply with
local codes, replace it with one that does. Follow the installation instructions
above on this page.
Install a discharge line so that water discharged from the combination
temperature and pressure relief valve will exit within 6 inches
(15.2 cm)
above, or any distance below the structural floor and cannot contact any live
electrical part. The discharge line is to be installed to allow for complete
drainage of both the combination temperature and pressure relief valve and
the discharge line. The discharge opening must not be subjected to blockage
or freezing.
DO NOT
thread, plug or cap the discharge line. It is
recommended that a minimum clearance of 4 inches
(10.2 cm)
be provided
on the side of the water heater for servicing and maintenance of the
combination temperature and pressure relief valve.
Do not place a valve between the combination temperature and pressure
relief valve and the tank.
