5.1 BOILER LOGBOOK
The logbook is included inside the Installation instructions. This
logbook should be completed by your installer to verify that
the correct installation and commissioning procedure was
followed.
Failure to complete the logbook may result in difficulties
should a problem arise with your appliance during the
guarantee period.
This logbook forms part of the industry’s Benchmark code of
practice for the installation, commissioning and servicing of
central heating systems.
All CORGI registered installers carry a CORGI identification card
and have a registration number. You can check your installer is
registered by telephoning 0870 4012300 or writing to:-
1 Elmwood
Chineham Business Park
Crockford Lane
Basingstoke
RG24 8WG
or check online at www.corgi-gas-safety.com
These appliances meet the requirements of;
Gas Appliance Directive 90/396/EEC
Efficiency of Hot Water Boilers Directive 92/42/EEC
Low Voltage Directive 92/42/EEC
Electromagnetic Compatibility Directive 92/31/EEC
Type test certified by:- Notified Body 0087 (Pin 87BT49).
Product/Production certified by:
Notified Body 0086.
For GB/IE only.
5.2 GENERAL CARE
The front panel should be cleaned with a damp cloth and mild
detergent. Do not use abrasive cleaners.
5.3 ROUTINE SERVICING
To ensure continued efficient operation of the appliance, it is
recommended that it is checked and serviced as necessary at
regular intervals. The frequency of servicing will depend upon
the particular installation conditions and usage but in general
once a year should be adequate. It is law that any service work
must be carried out by a competent person such as British Gas
or other CORGI Registered personnel.
5.5 PLUMING FROM TERMINAL
Like all condensing boilers this appliance will produce a plume
of condensation from the flue terminal. This is due to the high
efficiency and hence low flue gas temperature of the boiler. It
is normal and not a fault indication.
The boiler is fitted with a condensate trap.
The condensate drain point must not be modified or blocked
(see section 7.6 of the installation manual).
5.4 EMERGENCY
WARNING - If a gas leak is suspected or exists, turn the gas
OFF at the incoming mains (adjacent to the meter), Do not
operate any electrical switches. Do not operate any
electrical appliances. Open al
l
lwindows and doors. Do not
smoke. Extinguish all naked lights. Phone the Transco 24
hour emergency
n
number immediately on 0800 111 999
(Do not call from a mobile phone).
For short or long periods
Switch the programmer and/or room thermostat switch to the
OFF
position.
NOTE:
The appliance is fitted with a frost protection device In
the event of very cold conditions. Providing there is mains
power supply to the appliance, the frost protection mode is
integral. If the system temperature falls below 5°C then the
boiler will fire on its minimum setting until a flow temperature
of 30°C is reached. Further protection can be incorporated by
using a system frost thermostat.
The pump will automatically operate for 1 minute in every 24
hours to prevent sticking.
5.6 TO TURN THE BOILER OFF
In the event of overheating, the boiler will shut down and the
digital display will show ‘1’. Allow the boiler to cool, then
briefly turn the CH control knob fully anti-clockwise to the
RESET/STANDBY position and then back to ‘ON’ within two
seconds.
If the fault persists, consult a CORGI Registered installer.
5.7 BOILER OVERHEAT PROTECTION
Glen Dimplex Boilers Limited is continually improving its products and therefore reserve the right to change product specifications without prior notice.

3.0 SAFETY
3.1 GENERAL SAFETY
6
© Dimplex Boilers 2008
It is the law that all gas appliances are installed by a competent
person in accordance with the above regulations. Failure to
install appliances correctly could lead to prosecution. It is in
your own interest, and that of safety, to ensure that the law is
complied with. If the appliance is damaged, turn off the
appliance and consult a CORGI registered engineer. If it is
known or suspected that a fault exists on the appliance it
MUST NOT
be used until the fault has been rectified by a
competent person.
DO NOT interfere with any sealed components and use the
appliance only in accordance wi
t
th these instructions.
This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities,
or lack experience and knowledge, unless they have been given
supervision or instructions concerning use of the appliance by
a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
3.2 CURRENT GAS SAFETY (INSTALLATION & USE) REGULATIONS
This appliance must be earthed.
Supply: 230V - 50Hz fused at 3A.
The method of connection to the mains supply must facilitate
complete isolation of the appliance. Either a 3A fused three pin
plug and unswitched shuttered socket outlet, or a 3A fused
double pole switch having a 3mm contact separation in both
poles, serving only the boiler (and its external controls), may
be used.
3.3 ELECTRICAL SUPPLY
1. A flat vertical area is required for the installation of the
boiler.
2. Where an open flued (B23) system is used then an air vent
must be provided in the same room or internal space of the
flue duct air inlet, with a minimum free area of:
Dimplex 24 = 88cm2
Dimplex 30 = 121.5cm2
Dimplex 38 = 159cm2
3. These dimensions include the necessary clearance around
the boiler for case removal, spanner access and air movement.
Additional clearances may be required for the passage of pipes
around local obstructions such as joists running parallel to the
front face of the boiler.
4. When installed in a cupboard or compartment it is not
permissible to store other objects in the cupboard. Additionally
no flammable objects/items must be allowed to come into
contact with the boiler.
5. The boiler does not require additional ventilation when it is
installed in a cupboard or compartment. The exception to this
is where an open flue system has been installed - See note
3.4.2.

1.2 SYSTEM PRESSURE GAUGE
The normal operating water pressure is shown when the
needle is in the GREEN section of the gauge between 1 and 2
bar.
If the pressure drops too low the system will need topping up
via the filling loop.
If the pressure exceeds 3 bar the pressure relief valve will
operate and a fault may be indicated. Contact your installer
(see section 1.9).

1.6 COMFORT MODE
In Comfort mode the boiler monitors your hot water usage for
24hrs to predict the following days hot water needs and
preheat itself.
In economy mode this option is not active.
When the indicator is lit it shows that the boiler is in comfort
mode.
To select economy mode turn the domestic hot water
temperature control briefly to the comfort position and back
again and the light will switch off. The boiler is now in
economy mode. Repeat the action to switch back to comfort
mode.
If you adjust the central heating temperature (set point), the
display will light and show the temperature you have set. After
10 seconds the display will revert to showing the current
boiler central heating temperature and the backlight will switch
off after a further 10 seconds.

5.3 ROUTINE SERVICING
To ensure continued efficient operation of the appliance, it is
recommended that it is checked and serviced as necessary at
regular intervals. The frequency of servicing will depend upon
the particular installation conditions and usage but in general
once a year should be adequate. It is law that any service work

5.5 PLUMING FROM TERMINAL
Like all condensing boilers this appliance will produce a plume
of condensation from the flue terminal. This is due to the high
efficiency and hence low flue gas temperature of the boiler. It
is normal and not a fault indication.
The boiler is fitted with a condensate trap.
The condensate drain point must not be modified or blocked
(see section 7.6 of the installation manual).
5.4 EMERGENCY

NOTE:
The appliance is fitted with a frost protection device In
the event of very cold conditions. Providing there is mains
power supply to the appliance, the frost protection mode is
integral. If the system temperature falls below 5°C then the
boiler will fire on its minimum setting until a flow temperature
of 30°C is reached. Further protection can be incorporated by
using a system frost thermostat.
The pump will automatically operate for 1 minute in every 24
hours to prevent sticking.
5.6 TO TURN THE BOILER OFF
In the event of overheating, the boiler will shut down and the
digital display will show ‘1’. Allow the boiler to cool, then
briefly turn the CH control knob fully anti-clockwise to the
RESET/STANDBY position and then back to ‘ON’ within two
seconds.
If the fault persists, consult a CORGI Registered installer.
