1. INTRODUCTION
The Logic Heat H is a heating only boiler, featuring full sequence
automatic spark ignition and fan assisted combustion. It is
designed to provide central heating and hot water when separate
hot water cylinder is installed.
Due to the high efciency of the boiler, condensate is produced from
the ue gases and this is drained to a suitable disposal point through
a plastic waste pipe at the base of the boiler. A condensate ‘plume’
will also be visible at the ue terminal.
SAFETY
Current Gas Safety (Installation & Use) Regulations or
rules in force.
In your own interest, and that of safety, it is the law that this
boiler must be installed by a Gas Safe Registered Engineer, in
accordance with the above regulations.
In IE, the installation must be carried out by a Registered Gas Installer
(RGII) and installed in accordance with the current edition of I.S. 813
“Domestic Gas Installations”, the current Building Regulations and
reference should be made to the current ETCI rules for electrical
installation.
It is essential that the instructions in this booklet are strictly
followed, for safe and economical operation of the boiler.
ELECTRICITY SUPPLY
This appliance must be earthed.
Supply: 230 V ~ 50 Hz. The fusing should be 3A.
IMPORTANT NOTES
• This appliance must not be operated without the casing
correctly tted and forming an adequate seal.
• If the boiler is installed in a compartment then the compartment
MUST NOT be used for storage purposes.
•
If it is known or suspected that a fault exists on the boiler then
it MUST NOT BE USED until the fault has been corrected by
a Gas Safe Registered Engineer or in IE a Registered Gas
Installer (RGII).
• Under NO circumstances should any of the sealed components
on this appliance be used incorrectly or tampered with.
This appliance can be used by children 8 years and
•
above.
Also persons with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge,
provided they have been given supervision or instruction
concerning use of the appliance in a safe way and
understand the hazards involved. Children shall not play
with the appliance. Cleaning and user maintenance
shall not be made by children without supervision.
All Gas Safe Register installers carry a Gas Safe Register ID card, and have a registration number. Both should be recorded in the
Benchmark Commissioning Checklist. You can check your installer by calling Gas Safe Register direct on 0800 4085500.
Ideal Boilers is a member of the Benchmark scheme and fully supports the aims of the
programme. Benchmark has been introduced to improve the standards of installation and
commissioning of central heating systems in the UK and to encourage the regular servicing of all
central heating systems to ensure safety and efciency.
THE BENCHMARK SERVICE INTERVAL RECORD MUST BE COMPLETED AFTER EACH SERVICE

TO START THE BOILER
If a programmer is tted refer to separate instructions for the
programmer before continuing.
Start the boiler as follows:
Check that the electricity supply to boiler is off.
1.
2. Set the mode knob (B) to ‘BOILER OFF’.
3. Set the Central Heating temperature knob (A) to ‘MAX’.
Switch on electricity to the boiler and check that all external
4.
controls, e.g. programmer, room thermostat and hot water
cylinder thermostat are on.
5. Set the mode knob (B) to ‘BOILER ON’.
The boiler will commence ignition sequence, supplying heat to the
central heating, if required.
Note. In normal operation the boiler status display (C) will show codes:
00 Standby - no demand for heat.
Central Heating being supplied
FP Boiler frost protection
- boiler will re if temperature is below 5ºC.
During normal operation the burner on indicator (D) will remain
illuminated when the burner is lit.
Note: If the boiler fails to light after ve attempts the fault code
will be displayed (refer to Fault Code page).
To Turn Off
Set the mode knob (B) to ‘BOILER OFF’.
CONTROL OF WATER TEMPERATURE
The boiler controls the central heating radiator temperature to a
maximum of 80oC, adjustable via the central heating temperature
knob (A).
Approximate temperatures for central heating:

EFFICIENT HEATING SYSTEM OPERATION
The boiler is a high efciency, condensing appliance which will
automatically adjust its output to match the demand for heat.
Therefore gas consumption is reduced as the heat demand is
reduced.
The boiler condenses water from the ue gases when
operating most efciently. To operate your boiler efciently
(using less gas) turn the central heating temperature knob
(A) to the ‘
‘ position or lower. In winter periods it may be
necessary to turn the knob towards the ‘MAX’ position to meet
heating requirements. This will depend on the house and
radiators used.
Reducing the room thermostat setting by 1ºC can reduce gas
consumption by up to 10%.
WEATHER COMPENSATION
When the Weather Compensation option is tted to the system
then the central heating temperature knob (A) becomes
a method of controlling room temperature. Turn the knob
clockwise to increase room temperature and anti-clockwise
to decrease room temperature. Once the desired setting has
been achieved, leave the knob in this position and the system
will automatically achieve the desired room temperature for all
outside weather conditions.
BOILER FROST PROTECTION
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF at the programmer
(if tted) ONLY. The mains supply should be left switched ON,
with the boiler thermostat left in the normal running position.
If no system frost protection is provided and frost is likely
during a short absence from home it is recommended to leave
the heating controls (if tted) at a reduced temperature setting.
For longer periods, the entire system should be drained.
BOILER RESTART
To restart the boiler, when directed in the listed fault codes
(see section 7) press the “RESTART” button (F). The boiler
will repeat its ignition sequence. If the boiler still fails to start
consult a Gas Safe Registered Engineer or an IE Registered
Gas Installer (RGII).
MAINS POWER OFF
To remove all power to the boiler the mains power switch must
be turned off.
