Bradford White 30S Installation & Operating Instruction Manual page 7

Water Connections Continued-
For protection against excessive temperature and pressure, install
temperature and pressure protective equipment required by local codes, but
no less than a combination temperature and pressure relief valve certified as
meeting the requirements for Relief Valves and Automatic Gas Shut-off
Devices for Hot Water Supply Systems, ANSIZ21.22, by a nationally
recognized testing laboratory that maintains periodic inspection of production
of listed equipment or materials. The temperature and pressure relief valve
shall be marked with a maximum set pressure not to exceed the maximum
working pressure of the water heater. The temperature and pressure relief
valve shall also have an hourly rated temperature steam BTU discharge
capacity not less than the hourly rating of the water heater.
Install the temperature and pressure relief valve into the opening provided
and marked for this purpose on the water heater. Install a drainpipe in the
opening of the temperature and pressure relief valve so that any discharge
from the valve will exit within 6 inches above, or at any distance below the
structural floor and cannot contact any live electrical part. The end of the
relief valve drainpipe opening should terminate near the floor drain or other
suitable location. Do not subject the discharge opening to blocking or
freezing or reduce its size under any circumstances. It is recommended that
a minimum clearance of 3" be provided on the side of the water heater for
servicing and maintenance of the temperature and pressure relief valve.
After the installation of all the water lines, open the main water supply valve
and fill the water heater. Open several hot water faucets to allow air to escape
from the system while the water heater is filling. When a steady stream of
water passes through the faucets, close them and check all connections for
possible leaks in the system.
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4 X 3/4
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM
EXCESSIVE TEMPERATURES AND PRESSURES.
Never operate the water heater without first being certain it is filled with
water.
This water heater can deliver scalding water temperatures at any faucet in the
system. Be careful whenever using hot water to avoid scalding injury. Certain
appliances require increased water temperatures (such as dishwashers and
automatic clothes washers). By setting this water heater to a higher water
temperature setting, you may create the potential for a scalding injury. To
protect against injury, install an anti-scalding tempering valve in the water
system. This valve will reduce point of discharge temperature by mixing cold
and hot water in branch water lines. Such valves are available from the local
plumbing supplier. Please consult the plumbing professional who installed the
water heater concerning this matter.
