Prevent Freezing; Prevent Oxygen Contamination; Eliminate System Air - FULTON Caliber Installation And Operation Manual

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 50%
glycol should be used.
Caliber boilers cannot be placed outdoors due to the potential for
condensate to freeze within the boiler. 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 ttings
Do not use oxygen permeable materials anywhere in the water system
Repair leaks in the system quickly
Eliminate ttings wherever possible
Use air elimination devices in system piping

Eliminate System Air

There is a factory-installed air eliminator (air vent). The air eliminator must
not be altered or removed. Additional air elimination recommendations are as
follows:
1. If a sealed diaphragm-type expansion tank is used, install an air eliminator
in the hot water piping at the air separator.
2. If an air cushion type expansion tank is used, pipe tank directly into boiler
supply.
3. On multi-zoned systems (or a system with both space and domestic water
heating), air elimination must be provided either in the common piping or
on every loop.
4. When the boiler is installed at a higher level than baseboard radiation (if
used), air elimination must be provided directly above the unit.

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
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.
