! WARNING !
External equipment operated at 230 volts should not be
serviced or repaired under adverse weather conditions.
1.7 BOILER DATA PLATE
Your boiler is fi 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 when registering the boiler.
This data plate can be found inside the boiler casing by removing
the front casing door (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.
2 USING YOUR
BOILER
2.1 LIGHTING YOUR BOILER
The lighting procedure is:
1. Ensure that:
a) There is su ffi cient fuel, of the correct type, in the
supply tank and that all fuel supply valves are open.
b) The water supply is on.
c) The electricity supply to the boiler is OFF.
d) The boiler On/O
ff switch is set to OFF.
e) The room thermostat (if fi tted) is at the desired setting.
f) The boiler thermostat is set to the required setting.
2. Switch the electricity supply to the boiler ON.
3. Set the boiler On/O ff switch to ON.
If fi tted, set the programmer to ON (either central heating
(CH) or hot water (HW)).
4. The boiler will now light automatically.
5. If a programmer is fi tted, refer to the instructions supplied
with the programmer and set the CH and HW functions to
TIMED.
The boiler will now operate during the ‘on’ periods set on the
programmer.
2.2 IF YOUR BOILER FAILS
TO LIGHT
Make the following checks:
1. Check that the boiler On/O ff switch is set to ON.
2. Check that the programmer (if fi tted) is working and is set to
ON (CH or HW).
3. Check that all thermostats are set to the desired setting and
are calling for heat.
4. Check if the burner ‘Lock-Out’ reset button on the burner
body (refer to Figure 1-1 for location) is lit.
If it is, press it to start the burner.
If the burner fails to light and goes to ‘Lock-Out’ again, check
that you have su ffi cient fuel in the storage tank and that the
fuel supply valve is open.
5. Check that the fi re valve in the oil supply line has not tripped.
6. Ensure that a fuse has not blown or that the electricity supply
has not failed.
7. Check to see if the overheat thermostat has operated (see
Section 2.5).
If the burner still fails to light after carrying out these checks then
a fault exists or the fuel supply is low. If you have su ffi cient fuel,
switch o ff the electricity supply to the boiler and contact your
service engineer.
2.3 TURNING OFF YOUR BOILER
To turn o ff your boiler:
• For short periods-
Set the On/O ff switch to OFF.
To restart, simply set the switch to On.
• For long periods-
Set the On/O ff switch to OFF and switch o ff the electricity
supply to the boiler. If required, the fuel supply valve may be
closed and the water and electricity supplies turned o ff at the
mains.
To restart, refer to Section 2.1 (Lighting your Boiler).
2.4 ABOUT YOUR FUEL
Grant Euro fl ame Condensing boilers only operate on Class C2
Kerosene to BS 2869:1998.
You should always quote this type of fuel when ordering from your
supplier.
Do not wait until the fuel runs out before you order some more
as sludge in the bottom of the tank may be drawn into the fuel
lines. If it is possible, switch o ff the boiler when the new supply is
delivered and leave the fuel to settle for an hour before restarting
the boiler.
2.5 BOILER CONTROLS
BOILER THERMOSTAT
This dial, located on the boiler thermostat, allows the temperature
of the water leaving the boiler to heat the radiators (and/or other
heat emitters if fi tted) and domestic hot water to be adjusted.
Refer to Figure 1-1 for the location of the control panel within the
boiler casing and for the details of the control panel.
! NOTE !
If you have a cylinder thermostat on your hot water
cylinder, this will control the temperature of your domestic
hot water.
The boiler thermostat setting must be equal to or greater
than the cylinder thermostat setting to enable the cylinder
thermostat to control the domestic hot water system.
OVERHEAT THERMOSTAT
Your boiler is fi tted with a safety overheat thermostat which
will automatically switch o ff the boiler in the case of a control
malfunction causing overheating.
If your boiler goes o
ff and you try to light it but nothing happens
and the ‘Lock-Out’ reset button on the burner is not lit, the
overheat thermostat has probably operated. The boiler will not
light until the overheat thermostat is reset.
To reset the overheat thermostat, unscrew the small plastic cap
marked “overheat reset” (see Figure 1-1), press the button and
replace the cap.
If this condition continually repeats, contact your service engineer.
