Meet Water Chemistry Requirements - FULTON Caliber Installation And Operation Manual

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.
The boiler must be disconnected at
the boiler shut o valve from the
gas supply piping system during any
pressure testing of the system.

CAUTION
Small levels of chlorides and/or sulfur
presence in the combustion air or
fuel will negatively impact the heat
exchanger components. Any presence
of these contaminants will void the
warranty.
Some soaps used for leak testing are
corrosive to certain types of metals.
Rinse all piping thoroughly with
clean water after leak check has been
completed.

Meet Water Chemistry Requirements

System water chemistry requirements are as follows:
Maximum hardness of 8.5 grains/150 ppm
Acceptable pH range of 7.5-10
Solids less than 2500 ppm
Alkalinity less than 500 ppm
Foreign matter: Oils, fats, grease, and other matter should be limited to 10
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. Appropriate ow rates and return water temperature may be achieved
through primary and secondary ow loops. Please refer to Figures 3 - 4 for
example systems. Multiple pumps, valves and heating zones operating
at a variety of conditions will cause system ow to vary. System design
professionals should consider the variety of conditions the heating system
will experience.
4. Operate the boiler in a closed-loop system using water or water/glycol
(not requiring a make-up water supply). A large amount of improperly
treated make-up water can cause premature failure of the heat exchanger
resulting from scale build up. Scale build up will reduce the e ciency and
useful life of the boiler.
5. Caliber boilers use high e ciency, small diameter tubing in the water side
of the boiler. Large particulates may become caught in the heat exchanger,
which could result in damage to the heat exchanger. Debris in the piping
must be kept to a minimum; use a suitable strainer upstream of the inlet to
the boiler.
