NOTICE:
The flow rate of hot water many vary when more than two faucets
(appliances, fixtures, etc) are being used simultaneously.
NOTICE:
The pipes MUST be completely drainable. If the hot water faucets are
located at a point higher than the water heater, place a drain valve at the lowest
point (see diagram to the left).
Relief Valve
A new pressure relief valve, complying with the Standard for relief Valves and
Automatic Gas shut off Devices for hot water supply systems, ANSI Z21.22, must
be installed at the hot water outlet connection of the water heater at the time of
installation, local codes shall govern the installation of relief valves.
For safe operation of the water heater, must be sure that:
●
The pressure rating of the relief valve must not exceed 150 PSI, the maximum
working pressure of the water heater as marked on the rating plate.
●
The BTU/Hr rating of the relief valve must equal or exceed the BTU/Hr input of
the water heater as marked on its rating plate.
●
No valve of any type should be installed between the relief valve and the water
heater.
●
Discharge from the relief valve should be piped to a suitable drain to eliminate
potential water heater damage. Piping used should be of a type approved for
the distribution of hot water.
●
Hot and cold water lines should be insulated up to the water heater.
●
The discharge line must be NO SMALLER than the outlet of the valve and must
pitch downward to allow complete drainage (by gravity) of the relief valve and
discharge line.
●
The end of the discharge line should not be threaded or concealed and should
be protected from freezing. No valve of any type, restriction or reducer coupling
should be installed in discharge line.
NOTICE:
The diagram below illustrates a pressure only relief valve. If local codes
require a combination temperature and pressure relief valve be installed, an
extension piece may be needed.
NOTICE:
Manual operation of relief valves should be performed at least once a
