Pentair Pressure Relief Valve 50 psi.

Note: Commerical Installation in Texas state required Pressure Relieft Valve for all ASME models.

PRESSURE RELIEF VALVE

Canadian code requires and some U.S. local codes may

require installation of a

pressure relief valve. Purchase

separately and install a 3/4" pressure relief valve comply-

ing with the ANSI/ASME Boiler and Pressure Vessel Code,

having a capacity equal to the Btu/hr rating of the heater.

The relief pressure of the valve MUST NOT EXCEED 50

PSI.

A 3/4" NPT connection is provided in the manifold for

installing a pressure relief valve. The relief valve must be

installed vertically. To install the valve, use a 3/4" brass

nipple and elbow (user supplied), as illustrated in Figure

19. No valve is allowed to be placed between the mani-

fold adapter and the relief valve.

To avoid water damage or scalding from operation of the

relief valve, install a drain pipe in the outlet of the pres-

sure relief valve that will direct water discharging from

the valve to a safe place for disposal. Do not install any

reducing couplings or valves in the drain pipe. The drain

pipe must be installed so as to allow complete drainage

from the valve and drain line. The relief valve should be

tested at least once a year by lifting the valve lever
