INTRODUCTION

1.1

ABOUT YOUR BOILER

The boiler is fully automatic once switched on, providing domestic
hot water at mains pressure on demand and central heating when
the hot water and heating system controls call for it.
Kitchen/Utility boilers have a 'mains on' neon, see Figure 2-1,
which lights when the boiler is switched on.
! NOTE !
The 'mains on' neon light does not necessarily indicate the
burner is firing.
Your boiler may be fitted with one of the following control options,
located either on the boiler control panel or in a convenient
position remote from the boiler:
• Option A - Programmable room thermostat only.
• Option B - Remote timer and room thermostat.
• Option C - Boiler-mounted 'plug-in' single channel 24 hour
mechanical timer and remote room thermostat.
• Option D - Remote two-channel programmer and room
thermostat.
Whatever type of control system is connected to your combi
boiler, it will allow you to set the operating times of your central
heating.
In the case of options A, B and C - domestic hot water will be
available continuously, providing the boiler is switched on,
irrespective of the central heating controls settings.
In the case of option D, you can set the operating times for both
central heating and domestic hot water using the heating and hot
water settings on the programmer.
1.2

BOILER CONTROLS ACCESS

To gain access to the boiler controls, pull the front panel forward
at the top to disengage the fixing clips, then lift it up and off the

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.
As all Grant combi boilers operate 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 efficiency using specialist flue 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 fitted, in which case refer to the
manufacturer's instructions for details on service life). The air
pressure charge of any expansion vessels fitted 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 fitted 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 removing
the front casing panel (see Section 1.2), and looking on the inside
of either the left or right hand casing panel (depending on model).
! 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.
