If your Boiler Fails to Light
Make the following checks:
1. Check that the boiler On/Off switch
is ON.
2. Check that the programmer is
working and is in an 'on' period.
3. Check that all thermostats are set to
the desired setting and are calling
for heat.
4. Check if the burner 'Lock-out'
indicator neon on the control panel
is lit. If it is, remove the upper front
casing panel and locate the lockout
reset button on the burner behind
the control panel. See Figure 3.
5. Press the Reset button on the
burner. If the burner fails to light and
goes to 'Lock-out' again, check that
you have sufficient fuel in the
storage tank and that the fuel
supply valve is open.
6. Check that the fire valve in the oil
supply line has not tripped.
7. Ensure that a fuse has not blown or
that the electricity supply has not
failed.
8. Check to see if the overheat
thermostat has operated (see the
section Overheat thermostat).
If the burner still fails to light after
carrying out these checks then a fault
exists. Switch off the electricity supply
to the boiler and contact your Service
engineer.
Turning off your Boiler
For short periods: Set the On/Off
switch to OFF.
To restart, simply set the switch to ON.
For long periods: Set the On/Off switch
to OFF and switch off the electricity
supply to the boiler. If required, the fuel
supply valve may be closed and the
water and electricity supplies turned off
at the mains.
To restart, refer to the full lighting
instructions given in the Section Lighting

About your Fuel
Grant Vortex Eco Wall Hung boilers
operate only 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. Sludge in the
bottom of the tank may be drawn into
the fuel lines. If it is possible, switch off
the boiler when the new supply is
delivered and leave the fuel to settle for
an hour before restarting the boiler.
General Notes and Care of
your System
Boiler Thermostat
This control allows adjustment of the
temperature of the water leaving the
boiler to heat the radiators and
domestic hot water.
Figure 3: Burner fuel pump
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 above the cylinder
thermostat setting to enable the
cylinder thermostat to control the
domestic hot water system.
Burner Lock-out Indicator and
Reset Button
If there is a burner malfunction, a built-in
safety circuit switches the burner off and
the 'Lock-out' indicator neon (on the
control panel) will light. Usually such
malfunctions are short lived and pressing
the reset button will restore normal
operation.
