Benchmark
The “Benchmark” initiative is the new code of practice to encourage 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 fulfilled his obligations to record the information required by the initiative.

General 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 system, 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 discharged 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.
