2 USING YOUR
BOILER
Boiler operation
Your boiler is fully automatic once switched
on, providing you with central heating and also
heating your domestic hot water (if you have a
hot water cylinder tted as part of the system).
For more information, refer to ‘The heating
controls and how to use them’.
The boiler controls and how
to use them
Your boiler is tted with a dual thermostat
control. This is located on the top of the boiler.
Figure 2-1: Dual thermostat
This dual thermostat incorporates two
separate temperature controls:
The boiler thermostat
This controls the temperature of the water
owing from your boiler to the heating system.
This should have been set by your installer to
the required temperature and should not be
adjusted.
The overheat thermostat
This is a safety device which will automatically
switch off your boiler should it overheat for any
reason.
The burner reset button
If there is a problem with the burner tted to
your boiler, a built-in safety system switches
the burner OFF and the red lockout reset
button on the burner will be lit.
Figure 2-2: Burner reset button
Usually such problems are short lived and
simply pressing the lockout reset button after
waiting a short while will restore normal burner
and boiler operation.
The heating controls and
how to use them
Your Grant Vortex Boiler House boiler will
usually be controlled by a domestic heating
control system.
The information below is only a general
description of the heating and hot water
system controls that you may have.
The operation and setting of these system
controls should have been explained to you by
your installer.
For full details of the correct setting and
operation, always refer to the manufacturer’s
user instructions provided with each of these
controls.
This control system will typically consist of the
following controls:
A heating timer or programmer
This device allows you to set the ON and
OFF times for your heating and (if it is a
programmer) the ON and OFF times for
your hot water heating also. Refer to the
manufacturer’s user instructions for guidance.
Page 6
User HandbookPage 6
A room thermostat
This allows you to set the required air
temperature. When the air temperature is
below this setting, the thermostat will ‘call’ for
the boiler to operate to provide heating.
The room thermostat is usually located in a
downstairs area such as the hallway or living
room. You may have more than one room
thermostat if your heating system is ‘zoned’.
Refer to the manufacturer’s user instructions
for guidance.
! NOTE !
For your boiler to operate to provide you
with heating, the programmer (or timer)
must be in an ‘ON’ period for heating AND
the room thermostat must be ‘calling’ for
heat.
A cylinder thermostat
This controls the temperature of the water in
your hot water cylinder (if tted), as long as
your cylinder is being heated by the boiler.
When the water temperature in the cylinder is
below the thermostat set temperature, it will
‘call’ for the boiler to operate to heat your hot
water.
! NOTE !
For your boiler to operate to heat your hot
water cylinder, the programmer (or timer)
must be in an ‘ON’ period for hot water
AND the cylinder thermostat must be
‘calling’ for heat.
Thermostat radiator valves (TRVs)
Your heating system may also include
Thermostatic Radiator Valves (or TRVs). If you
have them, these will be tted on some or all
of your heating system radiators.
A TRV is a self-regulating valve, i.e. not
connected to the other heating system controls
such as the programmer and room thermostat,
designed to regulate the temperature in the
room in which it is situated.
It senses the air temperature around it and
controls the water ow to the radiator on which
it is tted to regulate its heat output to the
room.
The head of the TRV can be rotated to set it
to give the required room temperature. Once
correctly set, it should ideally be left in that
position and not used as an on/off control for
the radiator.
As the correct operation of the TRV is based
on it sensing the room air temperature, take
care not to cover the TRV head, e.g. with
curtains.
You should refer to the manufacturer’s
operating instructions for further details on
both the setting and use of TRVs.
Turning the boiler ON/OFF
Switching ON
Start the boiler as follows:
1. First, check that the electricity supply to the
boiler is OFF.
2. Make sure that there is sufcient fuel, of
the correct type, in the oil storage tank.
3. Check that all valves in the fuel supply pipe
are open.
4. Next, check that the programmer (if tted)
is set to the required settings for both
heating and hot water. This should have
been done by your installer but refer to the
manufacturer’s user instructions if you wish
to check or change the settings.
5. Check that the room thermostat is set to
the required temperature.
6. Switch on the electricity supply to the
boiler.
7. The boiler will start as soon as the
electricity supply is switched ON.
Switching OFF
If you just want to switch your boiler OFF for a
short period:
• Switch OFF the electricity supply to the
boiler.
To re-start your boiler, follow the instructions
given in the section above (switching on).
Page 7
User Handbook Page 7
Fuel for your boiler
Your Grant Vortex Boiler House boiler can only
be operated on Kerosene (Class C2 to BS
2869).
Always quote this type of fuel when ordering
from your supplier.
If your boiler operates on Bio-Kerosene, your
installer should have informed you of this and
explained how to order this from your supplier.
! NOTE !
Please do not wait for the fuel to run out
before you order more!
If you do, sludge in the bottom of the tank
may be drawn in to the oil supply pipe
and cause a blockage.
Don’t forget to switch your boiler OFF when
your tank is being lled and leave the fuel to
settle for an hour after lling before re-starting
the boiler.
Electricity supply
The boiler requires a ~230 1ph 50Hz supply. It
must be protected by a 5A fuse.
! WARNING !
The electricity connections to the boiler
must be earthed.
3 CARE OF YOUR
BOILER
Checking system pressure
(sealed system only)
If your boiler is operating on a sealed heating
system, your installer will have pressurised
the system and should have told you (or set it
on the pressure gauge) the system pressure
when cold (this is normally between 0.5 and
1.0 bar, which will increase slightly when hot).

Normal Operating
Pressure Range
NOTES:
Figure 3-1: Pressure gauge
You should frequently check that the system
pressure is correct. If the pressure (when
cold) is below the set pressure mentioned
above, you can re-pressurise the system. If
this is frequently required, ask your installer or
service engineer to check the heating system
for leaks and to check the expansion vessel air
charge.
Automatic air vent
The boiler or system will be tted with an
automatic air vent to remove air from the
system. Any air trapped in the radiators should
be removed by venting the radiators using the
vent screw at the top of each radiator. Only
vent a radiator if the top is cool and the bottom
is hot. Excessive venting will reduce the
system pressure, so only vent when necessary
and check the system pressure as mentioned
above.
Re-pressurise the system if necessary.
Page 8
User HandbookPage 8
Safety valve
The sealed system is tted with a safety valve
to release excess pressure from the system.
If water or steam is emitted from the end of
the safety valve discharge pipe, switch off the
boiler and contact your installer or service
engineer.
To ll or top up your sealed system
Figure 3-2: Sealed system lling loop arrangement
Firstly, check the boiler and circulating pump
are switched off and any automatic air vents
on the system are open.
Next, Connect exible lling loop* between the
two lling valves.
Then, open the lling valve on mains water
end of lling loop (the valve is open when
operating lever is in line with valve).
Also, open the lling valve on heating system
end of lling loop to allow water to ow into
system (valve is open when operating lever is
in line with valve).
When pressure gauge shows required system
pressure (refer to the ‘checking system
pressure’ section on page 7), close lling valve
on heating system.
Now, Vent each radiator to remove any air –
starting with the lowest one on the system, i.e
downstairs.
Locate the circulating pump(s) and vent the
pump(s) – unscrew the plug from the centre
of the pump and remove. Using a suitable
screwdriver rotate the shaft of the pump about
one turn. When water starts to trickle out,
replace the plug.
Now, check the system pressure on the gauge.
If necessary, re-open the lling valve on the
system until the gauge shows the required
pressure. Take care not to over ll!
Finally, close both lling valves and disconnect
the lling loop at one end only. Take care as
the lling loop may contain water!
* If you cannot locate the lling loop, please
contact your installer.
! NOTE !
If the system has been drained down or
requires frequent topping up, then the
level of inhibitor will need to be checked
by your installer.
Expansion vessel
(sealed system only)
The expansion vessel (red vessel usually
attached to boiler) must be checked annually
to ensure that there is a 1.0 bar air charge in
the vessel. Failure to do this will invalidate the
boiler guarantee.
! NOTE !
The pressure shown on the system
pressure gauge is not the air charge
pressure in the vessel.
Ventilation
Always ensure the boiler has adequate
ventilation. Any ventilation provided by the
installer must not be obstructed. You should
periodically check that they are clear.
Do not attempt to ‘box in’ or build a
compartment around it before consulting
your installer. If the boiler is installed in a
compartment, then that compartment must not
be used for storage purposes.
For safety reasons, do not place any
combustible material around or on the boiler or
ue pipe.
Flue terminal and
condensate disposal
Flue terminal
If your boiler ue system has a terminal on the
outside wall, make sure that the terminal is not
damaged or obstructed in any way.
A wire mesh guard is required if the terminal is
less than 2 metres above ground level. If one
is required, contact your installer.
You should periodically check for and remove
any obstructions, e.g. cut back any bushes
that may have grow over the terminal. Do
not stack anything against or in front of the
terminal.
In severe conditions, check that the terminal
does not become blocked by snow.
Page 9
User Handbook Page 9
‘Pluming’ from the ue terminal
Whilst operating, it is quite normal for
the boiler to produce a white plume of
condensation vapour from the ue terminal.
This is due to the high efciency of the boiler
and may be particularly evident with low
outdoor temperatures.
Condensate disposal
During the operation of the boiler, condensate
is produced from the ue gases and this is
drained to a suitable disposal point through the
plastic waste pipe on the left hand side of the
boiler.
The condensate drain must not be modied or
blocked.
Blockage of the condensate drain, caused by
debris or freezing can cause automatic shutdown of the boiler. If you suspect freezing
and the pipe run is accessible, you can try to
free the obstruction by pouring hot water over
the exposed pipe and clearing any blockage
from the end of the pipe. If this fails to remedy
the problem, you should contact your service
engineer.
Servicing
The boiler should be serviced at least every 12
months.
Regular boiler servicing (ideally before the
start of the heating season) ensures your
boiler is working safely, efciently and reliably.
This is also a condition of the second year
manufacturer’s guarantee.
The nozzle and braided oil hose should be
replaced annually.
• Have the boiler serviced regularly by a
competent, OFTEC registered (or Grant
UK approved) engineer.
• Have any repair work carried out by a
competent, OFTEC registered (or Grant
UK approved) engineer.
• Always use Grant UK approved spares
to help maintain the efciency, safety and
reliability of the appliance.
When should the boiler be serviced?
A service must be completed every 12 months
from the date of installation to maintain your
guarantee. This is also a condition of the
second year manufacturer’s guarantee.
The nozzle and braided oil hose should be
replaced annually and on sealed systems, the
expansion vessel air charge must be checked.
Please make sure that your engineer has
recorded the service information in the Service
Log at the rear of this user handbook. You will
be asked for your service history on any inguarantee repair visit.
Cleaning your boiler
Lightly wipe over the case with a damp cloth
and a little detergent then dried completely. Do
not use abrasive pads or cleaners.
Take care not to touch any hot surfaces.
Frost protection
Your installer may have tted a frost
thermostat. If not and you are likely to be away
for a short time, leave the boiler on with the
boiler thermostat set at a low setting.
If the boiler is not going to be used for longer
periods, the boiler and system should be
drained.
Contact your service engineer for draining and
lling the system.

4 FAULT FINDING
If your boiler fails to start
Things to check before calling Grant UK or your service engineer
In line with our current guarantee policy, we would ask that you check through the following
information to identify any problems external to the boiler prior to requesting a service engineers
visit.
Should the problem be found to be other than with the appliance, we reserve the right to levy a
charge for the visit or for any pre-arranged visit where access is not gained by the engineer.
Problem Solution
There is no
power to the
boiler
• Is the electrical supply to the boiler switched ON?
• Has the fuse in the electrical supply to the boiler blown? If so, t a replacement 5A
fuse only.
• Has the overheat thermostat tripped and switched the boiler OFF? Refer to ‘The
overheat thermostat’ section on page 5.
There has been
a power cut
• If the electricity supply fails, the boiler will not operate. It should relight automatically
when the supply is restored.
If a programmer is tted, it will retain the time settings for up to 24 hours and will not
have to be reset to the correct time of day when the supply is restored (the display will
remain for up to 1 hour, but will re-appear when the supply is restored).
There is no
heating or hot
water
• Is the programmer (if tted) working and in an ON period for heating or hot water?
If not, set the programmer to ON. Refer to the manufacturer’s user instructions for the
programmer for guidance if necessary.
• Are the room thermostat and cylinder thermostat set to the required settings and
‘calling’ for heat?
• Sealed systems – check that the system pressure is correct (refer to Section 3). If
necessary, top up the system (refer to page 8).
• Your boiler is tted with a safety overheat thermostat which will automatically switch
off the boiler in the case of a control malfunction causing overheating.
If your boiler goes off 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 thermostat is reset.
To reset, unscrew the small plastic cap marked reset (refer to Figure 2-1), press the
button then replace the cap.
If this condition continually repeats, contact your installer or service engineer.
The burner is
not operating
• Is the red lockout button on the burner lit? If there is a problem with the burner tted to
your boiler, a built-in safety system switches the burner OFF and the red lockout reset
button on the burner will be lit. Refer to Figure 2-2 for the position of the lockout reset
button.
Usually such problems are short lived and simply pressing the lockout reset button
after waiting a short while will restore normal burner and boiler operation.
• If it is, press the button to re-start the burner.
• If the burner fails to light and the red lockout is lit again, is there sufcient fuel in
the oil storage tank and are all the valves in the oil supply pipe open?
• Has the re valve in the oil supply pipe tripped shutting off the ow of oil?
• Check that you have fuel in the tank. Some sight gauges have a button that must be
pulled out, or pressed in, to obtain an up to date reading.
• Check that the remote acting re valve has not tripped.
• Locate the re valve (it should be in the oil line, just before it enters the building)
and reset it, following the operating instructions supplied with the valve. Most
types commonly in use have a reset button which must be pressed in order to
allow fuel through.
You have run
out of heating oil
• If you run out of fuel, the oil line will require purging of air after you tank has been
lled. Contact your installer or service engineer to do this for you.
If your boiler still fails to start after carrying out these checks, then there is a fault.
Switch off the electricity supply to the boiler and contact your installer or service engineer.

Hard water advice (for Combi boilers only)
If you live in a hard water area, protection against scaling must
be given to the domestic hot water heat exchanger of your
combination boiler.
You should t an appropriate scale inhibitor or water softener as
any breakdown caused by water scaling is not covered by the
manufacturer’s guarantee. Ask your installer for advice.
