INSTALLATION
!
WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Ensure all labels on the boiler are
legible. All connections and safety
devices, both mechanical and
electrical, must be kept clean, with
ease of access for inspection, use and
maintenance.
Do not store or use gasoline or other
fl ammable vapors and liquids or
corrosive materials in the vicinity of
this or any other appliances.
6. Install
fi ltration to remove particulates if appropriate. A #10 mesh size is
suggested.
7. Install bypass chemical feeder for corrosion inhibitor maintenance if
appropriate.
8. Install corrosion coupon holder to assess corrosion inhibitor performance if
appropriate.
9. Before installing a Endura boiler into a hydronic loop, be sure that the
system piping and any other components of the system are clean and free
of debris and any foreign matter. The hydronic system must be completely
fl ushed prior to installing the boiler itself.
NOTE:
Although motorized isolation valves are not required in a primary
only arrangement , they can help ensure system eff ectiveness. Proper
control strategy must be used to ensure fl ow paths in the hydronic loop and
residual heat in pressure vessel can be adequately dispersed when a boiler
is disabled.
Meet Water Chemistry Requirements
System water chemistry requirements are as follows:
pH: Range of 8.5 - 10.5
Oxygen: Less than 250 ppb (operating condition)
Total Iron/Copper: Less than 5 ppm
Corrosion Inhibitor: Capable of maintaining iron corrosion rates <2 mpy.
Due to changing environmental restrictions a non-heavy metal ALL
ORGANIC inhibitor is recommended which is designed for multi metal
systems including ferrous metals and yellow metals such as copper and
brass.
Chloride: Less than 200 ppm
Adhere to the following:
1. Refer to your water conditioning or chemical treatment supplier for
analysis and recommendations for proper system conditions.
2. Follow a program with appropriate monitoring and maintenance of system
water conditions as provided by your water conditioning or chemical
treatment supplier.
3. If RO/DI water is used as a source for hydronic loop water or makeup water,
it must be neutralized to a pH of 8.5 - 10.5 prior to entering the boiler.
Failure to neutralize the RO/DI water will void the pressure vessel warranty
and may cause high general corrosion rates.
The system must have an automatic pH controller to monitor and log the
levels. This must be independent of other chemical feed systems.
