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 is in compliance 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 in
(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 in
(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.
