System Details - Baxi Combi 130 HE Installation And Servicing Instructions

• Treatment of Water Circulating Systems
All water circulating systems will be subject to corrosion
unless an appropriate water treatment is applied.
Without treatment the efficiency of the system will
deteriorate as corrosion sludge accumulates within the
system, risking damage to pump and valves, boiler
noise and circulation problems.
For optimum performance after installation this boiler
and its associated central heating system must be
flushed in accordance with the guidelines given in BS
7593:1992. "Treatment of water in domestic hot water
central heating systems".
This must involve the use of a proprietary cleanser, such
as BetzDearborn Sentinel X300 or X400, Fernox
Superfloc or Salamander System Cleanser. Full
instructions are supplied with the products, but for
immediate information please contact BetzDearborn
(0044 (0)151 420 9563), Fernox (0044 (0)1799 550 811)
or Salamander (0044 (0)121 378 0952) directly.
For long term protection against corrosion and scale,
after flushing it is necessary that an inhibitor such as
BetzDearborn Sentinel X100, Fernox MB-1 or Copal or
Salamander System Inhibitor is dosed in accordance
with the guidelines given in BS 7593:1992.
Failure to flush and add inhibitor to the system will
invalidate the appliance warranty.

6.0 System Details

6.1 Information
In GB it is necessary to comply with the Water
Supply (Water Fittings) Regulations 1999 (or for
Scotland, The Water Byelaws 2000, Scotland).
The Baxi Combi 130 HE Combination Boiler is an
Approved Product under the Water Regulations.
To comply with the Water Regulations your attention
is drawn to The Water Regulations Advisory Service
(WRAS) which gives full details of the requirements.
In IE the requirements given in the current edition of
I.S. 813 "Domestic Gas Installations" and the current
Building Regulations must be followed.
6.2 Central Heating Circuit
1. The appliance is suitable for fully pumped SEALED
SYSTEMS ONLY.
This boiler is fitted with a flow switch interlock that
prevents it from firing when the heating demand is
satisfied.
The boiler is designed so that it will heat the house to
the desired room temperature as quickly as possible
by running at the maximum radiator temperature of
82°C.
Once this room temperature is achieved the boiler will
then reduce the radiator temperature to as low a level
as possible, while still achieving the desired room
temperature, thereby giving the most efficient use of
gas and the most comfortable room temperature
possible.
The boiler will be able to achieve this performance if a
room thermostat is fitted or with a fully TRV'd
system without a bypass. If the system is fully
TRV'd with a bypass then this feature will not be
available, in this case the radiator temperature can be
reduced to provide more efficient operation. (see User
instructions).
• If the hot water delivery is greater than 18
litres/minute the flow regulator must be fitted to the
Domestic Hot Water inlet (A pint milk bottle will fill in
under 2 seconds).
• If the boiler is to be uprated to 100,000 Btu/hr CH
output, an extra standard pump will be required and the
commissioning procedure will take approximately 30
minutes longer.
• The condensate drain and pipes must be free from
leaks.
• Any timer and thermostat should be removed before
installing optional Intellistat as it will override their
operation.
