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 page 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.
CENTRAL HEATING
The Atlantic combi 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 SM-1 PRO, FERNOX,
MBI, ADEY MC1, SENTINEL X100 or CALMAG CM100
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 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
Domestic Hot Water
1. The DHW service must be in accordance with BS.5546 &
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 Section 3.20. 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. If the shower/mixer valve does not incorporate non-return
valves the following must be followed:
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 (200 ppm), 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.
Cold water, rising main and pipework in exposed areas
need to be suitably lagged to prevent freezing.
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 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.
