WARNING
If the water supply must be
temporarily disconnected, the
boilers must be turned off to prevent
accidental fl ue gas emission into the
boiler room.

CAUTION
Care needs to be taken to eliminate
oxygen from the water system, as
excess oxygen in the system will
reduce the life of any boiler. The
boiler warranty does not cover heat
exchanger replacement due to oxygen
contamination of boiler water.
Heat exchanger failure due to
inappropriate water quality, foreign
matter or debris damage is not covered
under the warranty.
If the piping system attached to this
unit will be chemically cleaned, the
boiler must be disconnected from the
system and a bypass installed so that
the chemical cleaning solution does
not circulate through the boiler.
The hydronic system should never be
fl ushed while the boiler is attached
to the system since the debris could
accumulate in the boiler and block
water from passing through the heat
exchanger. This will lead to premature
boiler failure.
§ 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 fl ow rates and return water temperature may be achieved
through primary and secondary fl ow loops. Please refer back to Figures
3 - 5 for example systems. Multiple pumps, valves and heating zones
operating at a variety of conditions will cause system fl 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 effi ciency and
useful life of the boiler.
¡ Prevent Freezing
It is imperative to prevent freezing; adhere to the following:
§ If water/glycol is to be used in the system, a hazard analysis should be
performed to determine proper use and disposal. No greater than 40%
glycol should be used.
§ Precautions for freeze protection are recommended for boiler installations
where freezing potential exists and for installations that will use sealed
combustion with potential for outdoor air to fall below freezing point.
¡ Prevent Oxygen Contamination
There are several ways to prevent boiler water oxygen contamination:
§ Minimize system leaks to minimize make up water requirement
§
Do not use open tanks or fi ttings
§ Do not use oxygen permeable materials anywhere in the water system
§ Repair leaks in the system quickly
§ Eliminate fi ttings wherever possible
§ Use air elimination devices in system piping
