Grant Vortex Oil Boilers
For short periods - Set the On/Off 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 Section 2.3.
1
Check that the boiler On/Off switch is ON.
2
Check that the programmer (if fitted) 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' reset button (on the
burner) 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 sufficient fuel in the
storage tank and that the fuel supply valve is open.
Check that the fire valve in the oil supply line has not
tripped
5
Ensure that a fuse has not blown or that the
electricity supply has not failed.
6
Check to see if the safety thermostat has operated
(see Section 2.7).
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.
Grant Vortex 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. 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.
2 - USER INSTRUCTIONS
1
Boiler thermostat - This control allows the
temperature of the water leaving the boiler to heat
the radiators and domestic hot water to be adjusted.
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 above the cylinder
thermostat setting to enable the cylinder thermostat
to control the domestic hot water system.
2
Burner Lock-out reset button - If there is a
burner malfunction, a built-in safety circuit
switches the burner off and the 'Lock-out' reset
button (on the burner) will light. On Kitchen
models a neon on the control panel also indicates a
burner lock-out (see Fig. A). Usually such
malfunctions are short lived and pressing the reset
button will restore normal operation.
If the burner continually goes to 'Lock-out' a fault
exists or the fuel supply is low. If you have sufficient
fuel, you will need to call your Service engineer.
3
Safety thermostat - Your boiler is fitted with a safety
overheat thermostat which will automatically switch
off the boiler in the case of a control malfunction
causing overheating. On Kitchen models a neon on
the control panel will illuminate to indicate the overheat
thermostat has operated (see Fig. A).
If your boiler goes off and you try to light it but
nothing happens and the 'Lock-out' reset button on the
burner (or the neon on the control panel) are not lit,
the overheat thermostat has probably operated. The
boiler will not light until the thermostat is reset. To
reset, unscrew the small plastic cap (see Fig. A), press
the button then replace the cap.
If this condition continually repeats, contact your
Service engineer.
4
Programmer (if fitted) - Refer to the instructions
supplied with the Programmer.
5
Ventilation - Always ensure that the boiler has
adequate ventilation. Any ventilation openings
provided by the Installer must not be obstructed.
Periodically check that they are clear.
Do not attempt to 'box in' the boiler or build a
compartment around it before consulting your
Installer.
Do not place any combustible material around or
on the boiler or flue pipe.
