1.1.11. PRESSURE RELIEF VALVE KIT
To complete the installation of the boiler, you must
install an approved 3/4”, maximum 30 PSI (2 bar)
pressure relief valve on the heating return.
A hydronic kit equipped with hydronic connections
and safety valve (see ‘VS’ fig. 9) is available and
supplied by RADIANT.
ATTENTION
The pressure relief valve MUST TO BE
INSTALLED in any case.
ATTENTION
The pressure relief valve should be placed
as close to the boiler as possible. No other valve
should be placed between the pressure relief valve
and the boiler.
DANGER
Improper installation of the pressure
relief valve may result in property damage, personal
injury, or death. Follow all instructions and guidelines
when installing the pressure relief valve. The valve
should be installed only by a licensed professional.
When installing the valve, follow these guidelines:
› Direct the discharge piping of the pressure relief
valve so that hot water will not splash on anyone
or any nearby equipment.
› Attach the discharge line to the pressure relief
valve and run the end of the line to within 6-12”
(150-300mm) of the floor.
› Ensure that the discharge line will allow free and
complete drainage without restriction. Do not
install a reducing coupling or other restriction
on the discharge line.
