1 INTRODUCTION
1.1 ABOUT YOUR BOILER
The boiler is fully automatic once switched on, providing central
heating (and also domestic hot water if you have a hot water
cylinder tted).
Wall hung boilers have a ‘mains on’ neon, see Figure 2-2, which
lights when the boiler is switched on.
! NOTE !
The ‘mains on’ neon light does not necessarily indicate the
burner is ring.
If your boiler is connected to a programmer, it will provide hot
water and central heating during the time periods set on the
programmer.
1.2 BOILER CONTROLS ACCESS
To gain access to the boiler controls, hinge the lower front panel
down by pulling it out at the top of the panel, as shown in Figure
1-1. This will provide you with access to the boiler control panel,
see Figure 2-2.
To gain access to the other boiler components (see Figure 2-1),
including the burner, pull the upper front panel out at the bottom
of the panel, and lift upwards to disengage the locking tabs at the
top of the panel.
1.3 WHAT THE INSTALLER SHOULD
LEAVE YOU WITH
• A completed OFTEC CD10 (installation completion report)
• A completed OFTEC CD11 (servicing and commissioning
report)
• The boiler installation and servicing instructions
• This user handbook
The installer should have advised you how to operate the boiler
and controls, and whether the boiler operates as part of a sealed
system or an open vented system.
If the boiler operates as part of a sealed system, the installer
should have shown you how to check and top up the heating
system should your system pressure drop. Also see Sections 3.1
and 3.2.
1.4 COMMISSIONING
Following installation, your boiler should be commissioned by a
compentant person, such as an OFTEC registered engineer, to
validate the guarantee.
During the commissioning process, your boiler will be set to its
optimum eciency using specialist ue gas analysis equipment.
Your installer should arrange for this to be carried out.
If required, Grant UK can provide details of OFTEC registered
commissioning engineers in your area.
1.5 ACTIVATING THE GUARANTEE
In order for your boiler’s full* guarantee to be activated, your
boiler must be registered with Grant UK within 30 days of its
installation**.
To register your boiler, please either call Grant UK on:
01380 736920 or visit the Grant UK website: www.grantuk.com.
Your installer may have registered the boiler on your behalf and
provided you with the relevant documentation.
*If registered within 30 days of installation, your boiler will come
with a 2 year guarantee. Extended guarantees are also available
upon request; please contact Grant UK for further details.
**If the boiler is not registered within 30 days of installation, your
boiler will come with a 12 month guarantee.
Please refer to the boiler installation and servicing instructions for
the full terms of the manufacturer’s guarantee.
1.6 BOILER SERVICING
Your boiler must be serviced every 12 months from the date of
installation to maintain the guarantee, for the entire duration of the
guarantee (this includes any extended guarantee that may have
been purchased).
The nozzle and braided oil hose should be replaced annually
(unless a ‘long life’ oil hose is tted, in which case refer to the
manufacturer’s instructions for details on service life). If the
boiler is part of a sealed system, the air pressure charge of any
expansion vessels tted to the system must be checked annually.
Please make sure that your installer has recorded the service
information in the Service Log at the back of these user
instructions. Should you ever need to utilise the product
guarantee, you will be asked to provide the service history of the
boiler.
1.7 BOILER DATA PLATE
Your boiler is tted with a data plate, which shows any engineers
who come to service or repair your boiler some basic information
they may need to know in order to carry out their required works.
The data plate also contains the boiler serial number, which is
required by Grant UK when registering the boiler.
This data plate can be found inside the boiler casing by hinging
the lower front panel down, and then removing the upper front
casing panel (see Section 1.2), and looking on the front of the
boiler heat exchanger.
! WARNING !
Interference with the boiler (or any sealed component) is
strictly forbidden, other than where information is given in
these user instructions.
Incorrect use of the boiler can result in danger to the user
and will invalidate the guarantee.
