Installation and Servicing
Section 1 - General
Note. Systems incorporating zone valves which could
completely cut o the ow through the system must also
include a bypass.
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.
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 ow 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.
1.17 WATER TREATMENT
1.16 SYSTEM BALANCING
Central Heating
The Logic 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 Heating
invalid.
Ideal Heating recommend Water Treatment in accordance
with the Benchmark Guidance Notes on Water Treatment in
Central Heating Systems.
If water treatment is used Ideal Heating 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.
This boiler can be used with a water softener. However, the
heating system should not be lled with softened water as
any softening chemicals could enhance corrosion of certain
materials inw the heating system, including aluminium and
steel. The heating system should always be lled from the
bypass on the water softener installation.
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. BS7593:2019 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 articially softened
water is NOT permitted.
4. Under no circumstances should the boiler be red before
the system has been thoroughly ushed.
