Benchmark
The “Benchmark” initiative is the new code of practice to encour-
age the correct installation, commissioning and servicing of
domestic central heating boilers and system equipment.
The “log-book” is a vital document that must be completed by the
installer at the time of installation. It confirms that the boiler has
been installed and commissioned according to the manufacturers
instructions and is one of the methods of demonstrating
compliance with the Building Regulations.
Without the completion of the “log-book”, manufacturers may
refuse to respond to a call–out from a householder, who will be
advised that he or she must call back the installer, who has not ful-
filled his obligations to record the information required by the ini-
tiative.

Safety precautions
Gas Safety (Installation and Use) Regulations
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 inter-
est, and that of safety, to ensure compliance with the law.
If you smell gas:
BTurn off gas service cock at the meter.
BOpen all doors and windows.
BDo not operate any electrical switches.
BDo not smoke.
BExtinguish any naked flames.
BCall your gas company.
If you smell fumes from the appliance:
BSwitch off appliance.
BOpen windows and doors.
BInform your heating engineer.
Fitting and modifications
BFitting of the appliance or any modifications to the appliance
may only be carried out by a competent person.
BFlue systems must not be modified in any way.
Maintenance
BWe recommend that you take out a maintenance contract
with a competent installer and have the appliance serviced at
regular intervals.
BEnsure that your Service Engineer uses only genuine spare
parts!
Combustible materials
BDo not store or use any combustible materials (paper, thin-
ners, paints etc.) in the vicinity of the appliance.

1General notes
To get the best from your appliance please read these instructions
carefully.
Central heating systems
During the first few hours of operation of the central heating sys-
tem, check that all radiators are being heated at an even rate. If the
top of a radiator is at a lower temperature than the bottom then it
should be vented by releasing air through the venting screw at the
top of the radiator. Ask your installer to show you how this is done.
Repeated venting will reduce the quantity of water in the system
and this must be replenished for safe and satisfactory operation of
the appliance. An open vented system will re-fill automatically.
Should water leaks be found in the system or excessive venting is
required then a service engineer must be contacted to inspect the
installation and rectify any fault.
Only additives that are compatible with aluminium may be used in
the system. Any incompatible additive used will invalidate the
guarantee. Contact Fernox or Sentinel for further details.
Condensate drain
This is a condensing appliance and the terminal will, at times, give
out a plume of water vapour. This is quite normal.
The appliance produces quantities of condense which is dis-
charged regularly through the siphon.
Ventilation
This is a room sealed appliance and does not require any air for
combustion from inside the house. If the appliance is fitted into a
cupboard or a compartment is built around the appliance after
installation then the compartment must be separated from the
boiler space by a perforated non-combustible partition as
described in BS6798.
Notwithstanding the requirements of BS6798, there is no need
for ventilation openings to be provided in the compartment
because of the low heat loss from the casing.
Do not allow the flue terminal fitted on the outside wall to become
obstructed or damaged.

Clearances
Your installer will have provided adequate space around the appli-
ance for safety and servicing access. Do not restrict this space
with the addition of cupboards, shelves etc. next to the appliance.
Room thermostat
A room thermostat should be fitted to control the central heating.
Refer to the instructions supplied with the thermostat for informa-
tion on siting and setting.
Thermostatic radiator valves
It is recommended that this type of valve is fitted to all the radia-
tors. It is a requirement that they are fitted, at least, in the sleeping
areas.They should conform to the requirements of BS2767:10.
Time Control
Separate time control of the space heating and the hot water sys-
tem is required using a twin-channel programmer or two or more
separate timers.
Cylinder Thermostat
A cylinder thermostat must be fitted to the cylinder which, when
used with a motorised valve, will give close control of the water
temperature.

3.2 Switching the Appliance On/Off
Switching on
BSwitch on the appliance at the master switch (I).
The indicator lamp shows green and the display will show the
primary flow temperature.
The trap filling programme ensures that the condensation trap is
filled after the appliance has been installed or after the appliance
has been out of use for a long period. For that reason, the appli-
ance remains at minimum heating output for 15 minutes.
Switching off
BSwitch off the appliance at the master switch (0).
The green indicator lamp goes out.
i
If the display alternates between -II- and the boiler
flow temperature, the trap filling programme is
active.
