These boilers incorporate a STAINLESS STEEL heat exchanger. For water conditions, please refer
to Section 5.4 - Recommended Water Conditions.
CAUTION
Heat exchanger failure due to inappropriate water quality, foreign matter or debris damage is not
covered under the warranty.
CAUTION
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.
CAUTION
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.

!
Frost protection mode will be initialised when the boiler temperature sensor readings drop to 5°C.
The boilers will re until the water temperature reaches 15°C. Upon reaching 15°C the pumps will
continue to run for the pre-set duration of their overrun (specied by parameter “P 07” in Installer+
mode).
!
WARNING
The application of any other treatment to this product other than those recommended by Fulton Ltd
may render the guarantee of Fulton Ltd invalid.
!
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.

WATER TREATMENT
1. It is most important that the correct concentration of the water treatment products is maintained
in accordance with the manufacturers’ instructions.
2. If the boiler is installed in an existing system any unsuitable additives MUST be removed by
thorough cleansing.
3. In hard water areas, treatment to prevent limescale may be necessary.
4. Under no circumstances should the boiler be red before the system has been thoroughly
ushed.

PREVENTING OXYGEN CONTAMINATION
1. There are several ways to prevent boiler water oxygen contamination:
2. Minimise system leaks to minimise make up water requirement
3. Do not use open tanks or ttings
4. Do not use oxygen permeable materials anywhere in the water system
5. Repair leaks in the system quickly
6. Eliminate ttings wherever possible
