Installation and Servicing
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 page 9.
Note. Systems incorporating zone valves which could completely cut off the flow through the system must also include a bypass.

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.

The application of any other treatment to this product may
render the guarantee of Esprit eco 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-MB-1, ADEY
MC1 or SENTINEL-x100 inhibitors and associated water
treatment products, which must be used in accordance with the
manufacturers’ instructions.
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.
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
together with Scalemaster in-line scale inhibitor 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 Inline Scale Inhibitor branded Ideal, which must be used
in accordance with the manufacturers’ instructions.
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. The domestic hot water service must be in accordance with
BS 5546 and BS 6700.
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 Frame 67. 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 (200ppm), 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 accomodate 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.
Cold water, rising main and pipework on exposed areas need to
be suitably lagged to prevent freezing.
Note. DHW Expansion Vessel Kit availabe from Ideal Boilers.
