All descriptions and illustrations provided in this manual have been carefully prepared but we reserve the right to make
changes and improvements in our products that may affect the accuracy of the information contained in this manual.
IMPORTANT NOTICE
For the first year all of our appliances are protected by our manufacturer’s guarantee which covers
both parts and labour.
As you would expect from , it is our aim to provide our valued customers with the best in after
sales and service. To take advantage of any extended warranty offered, all you have to do is to
adhere to these 3 simple conditions:
• The installation must be carried out to Manufacturers/Benchmark Standards by a Gas Safe
Registered Engineer, and recorded in the installation manual.
• The appliance must be registered with both and Gas Safe within 30 days of installation.
• The appliance must be serviced annually, by a Gas Safe registered engineer-ensuring that the
Benchmark service record in the installation manual is completed.
Failure to comply with the above will result in only the 12 month warranty being offered.
In the absence of any proof of purchase, the 12 month warranty period will commence from the date
of manufacture of the boiler as shown on the appliance data plate.

THE BENCHMARK SCHEME
The manufacturer is a licensed member of the Benchmark Scheme which aims to improve the standards
of installation and commissioning of domestic heating and hot water systems in the UK and to encourage
regular servicing to optimise safety, efficiency and performance.
Benchmark is managed and promoted by the Heating and Hotwater Industry Council.
For more information visit www.centralheating.co.uk
Please ensure that the installer has fully completed the Benchmark Checklist in the use and maintenance
section of the installation instructions supplied with the product and that you have signed it to say that you
have received a full and clear explanation of its operation.
The installer is legally required to complete a commissioning checklist as a means of complyng with the
appropriate Building Regulations (England and Wales).
All installations must be notified to Local Area Building Control either directly or through a Competent
Persons Scheme.
A Building Regulations Compliance Certificate will then be issued to the customer who should, on receipt,
write the Notification Number on the Benchmark Checklist.
This product should be serviced regularly to optimise its safety, efficiency and performance.
The service engineer should complete the relevant Service Record on the Benchmark Checklist after each
service.
The Benchmark Checklist may be required in the event of any warranty work.

THE GAS SAFETY (INSTALLATION AND
USE) REGULATIONS 1996.
It is the law that all gas appliances
are installed by a registered 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.

The family
is a fully automatic, wall mounted, room
sealed, fan assisted range of combination
boilers. When operating in winter mode,
the appliance provides central heating
as required and produces instantaneous
hot water upon demand. When operating
in summer mode, the central heating is
not operational however the appliance
continues to supply hot water whenever
it is required.

family is a fully automatic, wall mounted,
room sealed, fan assisted range of
system boilers. The boiler is fitted with
a divertor valve which enables the boiler
to be directly connected to a hot water
cylinder.

  - a
demand of hot water will be sensed
by the appliance detecting water flow
(providing that the flow rate is above 2
l/m - 0.5 gal/min).
The fan will start and the burner will
light at full output. If the draw off rate is
near the maximum design flow rate the
appliance will run continuously at full
output until a tap is either turned off or
the flow rate is reduced in which case
the heat output will reduce accordingly
to maintain a steady temperature.
Hot water is made available almost
immediately at the appliance outlet, but
the final temperature and time taken
for the hot water to reach a tap depends
upon the potentiometer setting, the rate
at which water is drawn off, and the
length of the pipe between the boiler and
the tap.
When the tap is turned off, the appliance
will revert to C.H. mode (if set on winter
position) otherwise the burner will be
extinguished pending the next demand
for hot water.

The heat output will be controlled by the

The first ignition of the boiler must
be carried out by qualified technical
personnel. Successively, if it is necessary
to start up the boiler again, adhere strictly
to the following instructions: open the
gas tap to allow the flow of the fuel.
Move the main switch of the system
to “ON”. When fuel is fed to the boiler,
a sequence of checks will be carried
out and the display shows the normal
condition of the functioning, always
indicating the pressure of the system. If
the blue luminous bar is on, this indicates
the presence of voltage.

In this way, leaving the electricity and
the fuel supply connected, the boiler
is protected from frost and from the
pump becoming jammed. If the boiler
is not used for a prolonged period, it is
advisable to disconnect the electricity
supply, by switching off the main switch
of the system, and to close the gas tap
and, if low temperatures are expected, to
completely empty the hydraulic circuits
to avoid pipes being broken by the
formation of ice in the pipes.

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 the law that any service work must
be carried out by a Gas Safe Register
registered engineer. Ensure that the
service is recorded in the installation
guide use and maintenance section.

The tappets that remain at the cen-

When the selector is in the “AUTO” position, boiler fun-
ctioning is automatically controlled on the basis of the
temperature levels and time periods set. The second
selector must be in the “RUN” position to start. The pro-
gramming procedure is described below:
– 
Set the selector to the “CLOCK“ position. Press “h” to
change the hour on the display, or “m” to change the
minutes. To set the day, press the “1…7” button until
the arrow is pointing to the correct day (1 = Monday… 7
= Sunday).
– 
The time clock has 8 on times and 8 off times. To make
it easier to use, the time clock is supplied with 3 on
times and 3 off times already set for each day of the
week, as shown below:
To select programmes other than those already set, move
the selector to position “P”; “0:001” will appear on the
display, in which the first three digits indicate the hour
and minutes, while the fourth digit identifies the program
number. Odd-numbered programs identify requests for
operation (day temperature), in which case the light bulb
symbol will appear on the display, while even-numbered
programs identify drops in temperature (night). Use the
“1…7” key to select the day of the week (from 1 to 7) or
days (1 ÷ 5, 6 - 7; 1 ÷ 6 or every day if the program is to be
repeated every day of the week). Set the hour and minutes
with the “h” and “m” buttons. Press “P” to store the ope-
ration in memory and go on to the next program. Repeat
the same procedure to set the
remaining programs.
When finished programming, set the selector to “RUN”
position.

The on and off time must be deleted for each program
to be deleted.
Set selector (2) to position “P”. Select the desired pro-
gram with button (3), then press button (4) to delete the
day setting (the triangular symbols for the days should
go away). If part of the program is deleted, when you
set selector (2) back to the “RUN” position an error will
appear in the clock display, referring to the program
which is incorrect.
To delete all programs, put the selector in position “P”
and press buttons (3) and (5) at the same time.

The SKIP function deactivates programs for the next
day and resumes regular programming 24 hours
later.
This function is useful if you will be out all day and
don’t need heating.
To start this function, press button (7), which is active
only when selector (2) is in “RUN” position.
Once you have selected the SKIP function, it will go into
effect at 0:00 of the next day for 24 hours.
You cannot turn it off once it has started, so regular
programming will not resume until 24 hours have pas-
sed.
