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 off 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.
3. Appropriate fl ow rates may be achieved through primary and secondary
fl ow loops. Please refer 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.
5. Caliber boilers use high effi 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.

 Prevent Freezing
It is imperative to prevent freezing; adhere to the following:
 If a water/glycol mix is to be used in the system, a hazard analysis should
be performed to determine proper use and disposal. No greater than 50%
glycol should be used.
 Caliber boilers cannot be placed outdoors. 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 temperature 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
