DANGER!
Notes relating to the heating system water.
Thoroughly flush the system before it is filled
with water. Use only untreated water or water
treatment product such as Sentinal X100 to fill
and top up the system.
When using water treatment, only products
suitable for use with Boulter Buderus heat
exchangers are permitted (e.g. Sentinel X100).
Your warranty is at risk if an incorrect water
treatment product is used in conjunction with
this appliance. For more information, contact
Boulter Buderus Product Support Department.
It is most important that the correct
concentration of the water treatment product is
maintained in accordance with the
manufacturer's instructions.
If the boiler is used in an existing system any
unsuitable additives MUST be removed by
thorough cleaning. BS.7593:1992 details the
steps necessary to clean a domestic central
heating system.
In hard water areas, treatment to prevent lime
scale may be necessary - however, the use of
artificially softened water is NOT permitted.
Under no circumstances should the boiler be
fired before the system has been thoroughly
flushed.
Do not use water softened in a salt bedding
exchanger.
Do not use anti-freeze or other additives.
The expansion vessel must be of sufficient
size.
When oxygen-permeable pipes are used (e. g.
for floor heating systems) the system must be
separated by means of heat exchangers.
Unsuitable heating water promotes sludge
formation and corrosion. This may cause
malfunctions and damage in the heat
exchanger.
This appliance is not suitable for gravity
central heating nor are they suitable for the
provision of gravity domestic hot water.
The boiler must be vented.
Drain cocks must be located in accessible
positions, which permits the draining of the
entire system. They should be at least ½" BSP
nominal size and be in accordance with
BS. 2879.
Subject to modifications resulting from technical improvements!

Notes relating to domestic hot water.
The boiler must not be used for direct hot water
supply.
The hot water storage cylinder must be of the
indirect type.
Single feed, indirect cylinders are not
recommended and must not be used on sealed
systems.
The hotwater cylinder and ancillary pipework,
not forming part of the useful heating surface,
should be lagged to prevent heat loss and any
possible freezing - particularly wher pipes run
throughroof spaces and ventilated underfloor
spaces.
The domestic hot water service must be in
accordance with BS 5546 and BS 6700.
Safe handling of substances
Care should be taken when handling the boiler's insulation,
which can cause irritation to the skin.
No asbestos, mercury or CFCs are included in any part of the
boiler and its manufacture.
