7 - INSTALLATION - Water connection
7.1 - Water connections
The boiler comes with the fi ttings shown in Figure 7-1.
7.2 - Supply and return piping
CAUTION!!!
All heating system piping must be installed
in accordance with the ANSI/ASME Boiler and Pressure
Vessel Code, Section IV. All applicable local codes and
ordinances must also be followed.
CAUTION!!!
This boiler must have adequate water
fl owing of 5 GPM through it whenever the burner is
on. Failure to do this will damage the unit and void the
warranty!
CAUTION!!!
Before connecting the boiler to the
heating system the heating system must be thoroughly
fl ushed to remove sediment, fl ux, fi lings and other
foreign matter. An approved inhibitor should be added
to the heating system water to prevent limestone and
magnetite deposits from forming and to protect the
boiler from galvanic corrosion.
CAUTION!!!
Any dirt or foreign matter which is
present in the heating circuit , might accumulate
inside the secondary domestic heat exchanger,
limiting the heat exchange and reducing the
production of domestic hot water
CAUTION!!!
The manufacturer cannot be held
responsible for any damage caused by incorrect use of
additives in the heating system.
CAUTION!!!
This boiler is equipped with an ASME
safety relief valve set at 30 psi (2 bar). The heating
system must be designed so that no piping or radiation
elements are higher than 65 ft (20 m) or else the
hydraulic head of the system will cause the relief valve
to open.
CAUTION!!!
Continual fresh make-up water will reduce
boiler life. Mineral buildup in the heat exchanger
reduces heat transfer, overheats the stainless steel
heat exchanger, and causes failure. Addition of oxygen
carried in by makeup water can cause internal corrosion
in system components. Leaks in boiler or piping must
be repaired at once to prevent makeup water entering
the boiler.
CAUTION!!!
This boiler can supply heating water at a
temperature up to 190°F (88°C). If the heating system is
built with materials not able to resist to this temperature,
you must to install a device that shut-off the boiler
before the material’s limit temperature.
