4 APPLICATION INFORMATION
4.1 L.P.H.W. system
4.1.1 Water temperature
Maximum water temperature is 110°C (high limit ther-
mostat).
Highest boiler water temperature is 95°C (control ther-
mostat).
Minimum return water temperature is 20°C at a flow rate
related to a
∆
t of 20°C (flow/return temp).
4.1.2 Water pressure
Boiler sections are factory pressure tested at 10 bar.
Maximum pressure test boiler block is 7,8 bar.
Maximum working pressure is 6 bar
Minimum working pressure is 0,8 bar at a maximum
working temperature of 110°C or 0,3 bar at a maximum
working temperature of 95°C.
4.1.3 Water flow
The minimum water flow through the boiler on shut down
is:
Output boiler in kW = m 3 /h
93
This minimum flow must be maintained for approxima-
tely 5 minutes after the burner stops firing to avoid high
temperature shut down due to residual heat gain.
Due to the design and manufacture of the boiler no
specific minimum water flow requirements exist other
then for overheating protection.
4.1.4 Water treatment
The system should be filled with mains cold water (for
the UK this will usually have a pH of between
7 and 8).
Pressurised installations with a boiler/system content
ratio of 1:10 or less should not require water treatment,
provided that the following conditions apply:
1. The system is flushed thoroughly to remove all fluxes
and debris and then filled completely once.
2. Make up water is limited to 5 % per annum.
3. The hardness of the water does not exceed 360 ppm
(20°D).
All scale deposits will reduce the efficiency of the boiler
and should be prevented. However provided the above
is complied with any scale produced will not be too
detrimental to the boiler efficiency and will not reduce
the anticipated life expectancy of the boiler.
Note: Scale deposits in excess of 3 to 5 mm will reduce
boiler efficiency and greatly increase the risk of prema-
ture casting failure.
