Installation and Servicing
SECTION 1 - GENERAL
The boiler does not normally need a bypass but at
least some radiators on the heating circuit, of load
of at least 10% of the minimum boiler output, must
be provided with twin lockshield valves so that this
minimum heating load is always available. See note
regarding thermostatic radiator valves on section 1.13.
Note. Systems incorporating zone valves which could
completely cut off the flow through the system must
also include a bypass.
BALANCING
1.
Set the programmer to ON.
Close the manual or thermostatic valves on all
radiators, leaving the twin lockshield valves (on the
radiators referred to above) in the OPEN position.
Turn up the room thermostat and adjust the
lockshield valve to give an uninterrupted flow
through the radiator.
These valves should now be left as set.
2.
Open all manual or thermostatic radiator valves
and adjust the lockshield valves on the remaining
radiators, to give around 20
o
C temperature drop at
each radiator.
3.
Adjust the room thermostat and programmer to
NORMAL settings.

1.19 WATER TREATMENT
CENTRAL HEATING
The Logic Code Combi ESP1 range of boilers have an
ALUMINIUM alloy heat exchanger.
IMPORTANT.
The application of any other treatment to this
product may render the guarantee of Ideal Boilers
Invalid.
Ideal Boilers
recommend Water Treatment in
accordance with the Benchmark Guidance Notes on
Water Treatment in Central Heating Systems.
If water treatment is used
Ideal Boilers recommend
only the use of
SCALEMASTER GOLD 100, FERNOX,
MBI, ADEY MC1 or SENTINEL X100
inhibitors and
associated water treatment products, which must
be used in accordance with the manufacturers’
instructions.
DOMESTIC HOT WATER
In hard water areas where mains water can exceed
200ppm Total Hardness (as defined by BS 7593:2006
Table 2) a scale reducing device should be fitted into
the boiler cold supply within the requirements of the
local water company. The use of artificially softened
water, however, is not permitted.
Ideal Boilers recommend the use of Fernox
Quantomat, Sentinel Combiguard,Calmag CalPhos
I scale reducing devices or Scalemaster In-line
Scale Inhibitor branded Ideal, which must be used in
accordance with the manufacturers’ instructions.
SYSTEM REQUIREMENTS - CONT’D
Domestic Hot Water
1. The DHW service must be in accordance with BS5546 & BS6700.
2. Refer to Table 1 for minimum and maximum working pressures.
In areas of low mains water pressures the domestic hot water
regulator may be removed from the DHW flow turbine cartridge.
Refer to Section 3.25. The boiler will require the flow rate to be
set to obtain a temperature rise of 35
o
C at the tap furthest from the
boiler.
3. The boilers are suitable for connection to most types of washing
machine and dishwasher appliances.
4. When connecting to suitable showers, ensure that:
a. The cold inlet to the boiler is fitted with an approved anti-
vacuum or syphon non-return valve.
b. Hot and cold water supplies to the shower are of equal pressure.
5. Hard Water Areas
Where the water hardness exceeds 200mg/litre, it is
recommended that a proprietary scale reducing device is fitted
into the boiler cold supply within the requirements of the local
water company.
IMPORTANT. Provision must be made to accommodate the
expansion of DHW contained within the appliance. If the DHW inlet
contains a back flow prevention device or non-return valve, e.g. a
water meter, then a mini expansion vessel should be fitted between
the device and the boiler in the cold inlet pipe.
Note.
DHW Expansion Vessel kit available from Ideal.

Notes.
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. BS 7593:2006 details the
steps necessary to clean a domestic heating system.
3. In hard water areas, treatment to prevent lime scale may be necessary
- however the use of artificially softened water is NOT permitted.
4. Under no circumstances should the boiler be fired before the system
has been thoroughly flushed.
