a
Caution!
The boiler may only be permanently operated
with its casing properly closed!
Otherwise, under unfavourable conditions, it can
result in material damage or even injury or
death.
h
Note!
When starting up particularly take the following
into consideration:
Before the heating circuit or charging circuit is
filled you must open the cap on the automatic
air vent which must remain open during
subsequent operation.
Use the bleeding program to bleed the heating
circuit or charging circuit (see Chapter 9.2).
6.1
Water circulation system
Detailed recommendations concerning the water circuit
system can be taken from BS 6798 and BS 5449, Part 1
(for "Small Bore” and "Micro Bore” central heating
installations). Lines which do not form part of the usable
heating surface should be insulated to prevent heat
losses and possible freezing up, especially where the
lines run under rooves and ventilated cellar rooms. The
drain connections must be easily-accessible, so that the
entire system including the boiler and hot water system
can be drained. The drain connections should be at least
1/2 " (BSP nominal size) and must be in accordance with
BS 2879.
The boiler is suitable for Minibore and Microbore sys-
tems. Water lines are to be copper pipes in accordance
with BS 2871, Part 1. These must be thoroughly cleaned,
especially when connecting a new boiler to an existing
system.
a
Caution!
To prevent deposition and severe damage to the
boiler and heating installation the cleaning
agent must be applied carefully and
subsequently removed from the heating
installation by draining it completely. Cleaning
agents should not remain in the heating
installation longer than 24 hours.
This cleaning process must take place before a new
boiler is fitted in accordance with BS 7593.
Recommendations on the use of system cleaning agents
can be obtained from Sentinel, Betz Dearborn Ltd.

Preparation of heating water
a
Caution!
If anti-freeze inhibitors are to be used it has
been found that Sentinel X500 and Fernox
Alphi-11 have no known incompatibility issues
with our boilers. Vaillant cannot guarantee the
compatibility and effectiveness of these
products in the rest of the heating installation
and accepts no liability or responsibility for
damage caused by use on non-recommended
anti-freeze inhibitor products.
Risk of damage if the heating water is treated with
unsuitable frost or corrosion protection agents.
Frost and corrosion protection agents can cause chang-
es to seals, noise during heating mode and may lead to
other consequential damage.
• Do not use any unsuitable frost or corrosion protec-
tion agents.
Mixing additives with the heating water can result in ma-
terial damage. However no incompatibility with Vaillant
boilers has been detected with proper use of the follow-
ing products over a long period.
• When using additives, follow the manufacturer's in-
structions without exception.
Vaillant accepts no liability for the compatibility of any
additive or its effectiveness in the rest of the heating in-
stallation.
