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

tted) is at the desired setting.

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.

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

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

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

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

ame 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 control panel, allows the

temperature of the water leaving the boiler to heat the radiators

(and/or other heat emmiters if

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 Figure 2-1 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

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
