Grant Euroflame condensing Indoor/Utility and Boiler House Oil Boilers
During the combustion process, hydrogen and oxygen
combine to produce heat and water vapour. The water
vapour produced is in the form of superheated steam in
the heat exchanger. This superheated steam contains
sensible heat (available heat) and latent heat (heat
locked up in the flue gas). A conventional boiler
cannot recover any of the latent heat and this energy is
lost to the atmosphere through the flue.
The Grant Euroflame condensing boiler contains an
extra heat exchanger which is designed to recover the
latent heat normally lost by a conventional boiler. It
does this by cooling the flue gases to below 90° C,
thus extracting more sensible heat and some of the
latent heat. This is achieved by cooling the flue gases
to their dew point (approximately 55° C).
To ensure maximum efficiency, the boiler return
temperature should be 55° C or less, this will enable
the latent heat to be condensed out of the flue gases.
The boiler will achieve nett thermal efficiencies of
100%.
To achieve maximum performance from the Grant
Euroflame condensing boiler, it is recommended that
the heating system is designed so that a temperature
differential of 20° C between the flow and return is
maintained. The use of modulating circulating pumps
(now widely available) and effective control systems
should be considered.
The Grant Euroflame condensing boiler will however
still operate at extremely high efficiencies even when
it is not in condensing mode and therefore is suitable
for fitting to an existing heating system without
alteration to the radiator sizes. The boiler is capable of
a maximum flow temperature of 75° C.
How a condensing boiler works
1.1
Heating system design considerations
1.2
To achieve the maximum efficiencies possible from the
Grant Euroflame condensing boiler, the heating system
should be designed to the following parameters:
Radiators:-
Flow temperature 70° C
Return temperature 50° C
Differential 20° C
Underfloor:-
Flow temperature 50° C
Return temperature 40° C
Differential 10° C
1 Size radiators with a mean water temperature of
60° C.
2 Design system controls with programmable room
thermostats or use weather compensating controls
to maintain return temperatures below 55° C.
The boiler should not be allowed to operate with
return temperatures of less than 40° C when the
system is up to operating temperature.
3 The use of a pipe stat is recommended to control
the return temperature when using weather
compensating controls.

2 - USER INSTRUCTIONS
The boiler is fully automatic once switched on, providing
central heating (and also heating your domestic hot water
if you have a hot water cylinder fitted).
A 'mains on' neon, see Fig. A, lights when the boiler is
switched on, but does not necessarily indicate the burner
is firing.
If your system includes a programmer, the boiler will
provide hot water and central heating during the
periods set on the programmer.
To gain acces to the controls, pull the front panel
forward at the top to disengage the fixing clips then lift
it up and off the boiler. To replace locate the bottom of
the panel over the fixing tags then push it towards the
boiler to engage the fixing clips.

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 Euroflame 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. 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. 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.
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 (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.
6 Flue terminal - The flue terminal on the outside
wall must not be obstructed or damaged.
In severe conditions check that the terminal does
not become blocked by snow.

7 Frost protection - Your Installer may have fitted 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. For longer
periods the boiler and system should be drained.
Contact your Service engineer for draining and
filling the system.
8 Cleaning and servicing - Lightly wipe over the
case with a damp cloth and a little detergent. Do
not use abrasive pads or cleaners.
You must have your boiler serviced at least once a
year to ensure safe and efficient operation. Contact
your Service engineer for further details.
9 Failure of electricity supply - If the electricity
supply fails, the boiler will not operate. It should
relight automatically when the supply is restored.
The boiler requires a 230/240 V ~ 50 Hz supply. It
must be protected by a 5 Amp fuse.
Warning: This appliance must be earthed.
If your boiler is operating on a sealed heating system,
the 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). If the pressure (when cold) is below the set
pressure mentioned above, you can re-pressurise the
system. If the system requires frequent re-pressurising,
ask your Installer or Service engineer to check the
heating system for leaks and to check the expansion
vessel air charge.
The boiler or system will be fitted 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.
2 - USER INSTRUCTIONS
The boiler or system may be fitted 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.
The expansion vessel air charge must be checked
annually. Failure to maintain an adequate air
charge in the vessel may invalidate the warranty.
To re-pressurise the system by adding water:
1 Only add water to the system when it is cold and
the boiler is off. Do not overfill.
2 Ensure the flexible filling loop (see Fig. B) is
connected and that the shut off valve connecting it
to the boiler is open and the double check valve at
the front is closed.
A valve is open when the operating lever is in line with
the valve, and closed when it is at right angles to it.
3 Gradually open the double check valve on the front
of the filling loop until water is heard to flow.
When the black needle of the pressure gauge is
between 0.5 and 1 bar, close the valve.
4 Vent each radiator in turn, starting with the lowest
one in the system, to remove air.
5 Continue to fill the system until the pressure gauge
indicates between 0.5 and 1.0 bar. Close the fill
point valve.
6 Repeat steps 4 and 5 as required.
7 Close the valves either side of the filling loop and
disconnect the loop.

4.4.2 Fuel pipes
1 Fuel supply pipes should be of copper tubing with
an external diameter of at least 10 mm.
Galvanised pipe must not be used.
All pipe connections should preferably use flared
fittings. Soldered connections must not be used on
oil pipes.
2 Flexible pipes must not be used outside the boiler case.
3 A remote sensing fire valve must be installed in the
fuel supply line (outside) where it enters the building,
with the sensing head located above the burner.
Recommendations are given in BS 5410:1:1997.
4 A metal bowl type filter with a replaceable micronic
filter must be fitted in the fuel supply line adjacent to
the boiler. A shut-off valve should be fitted before the
filter, to allow the filter to be serviced.
5 A flexible fuel hose, adaptor and 1/4" BSP isolation
valve are supplied loose with the boiler for the final
connection to the burner. If a two pipe system or
'Tiger Loop' type de-aerator is used, an additional
flexible fuel hose (600 mm) and 3/8" to 1/4" BSP male
adaptor are available to purchase from your local
stockist.
6 Metal braided flexible hoses should be replaced
annually when the boiler is serviced. Long life
flexible pipes should be inspected annually and
replaced at least every 60 months.
4.4.3 Single pipe system - (See Fig. 3)
1 Where the storage tank outlet is above the burner
the single pipe system should be used. The height
of the tank above the burner limits the length of
pipe run from the tank to the burner.
2 As supplied the burner is suitable for a single pipe
system.
4.4.4 Two pipe system - (See Fig. 4)
1 When the storage tank outlet is below the burner,
the two pipe system should be used. The pipe runs
should be as shown in Fig. 4. The return pipe
should be at the same level in the tank as the
supply pipe, both being 75 to 100 mm above the
base of the tank. The pipe ends should be a
sufficient distance apart so as to prevent any
sediment disturbed by the return entering the
supply pipe.
2 Avoid the bottom of the tank being more than 3 m
below the burner.
3 A non-return valve should be fitted in the supply
pipe together with the filter and fire valve. A nonreturn valve should be fitted in the return pipe if
the top of the tank is above the burner.
4 To be used with a two-pipe system, the burner
must be fitted with an additional flexible fuel hose
(a flexible fuel hose (600 mm) and 3/8" to 1/4" BSP
male adaptor are available to purchase from your
local stockist. See Section 4.4.6.
5 The pump vacuum should not exceed 0.4 bar.
Beyond this limit gas is released from the oil.
For guidance on installation of top outlet fuel tanks and
suction oil supply sizing, see OFTEC booklet T1/139.

It should be both the designer's and installer's concern
that the air required for these functions be introduced
so as to cause as little discomfort as possible to the
building occupants and thus to offer them the least
temptation to obstruct the ventilators.
Further details may be obtained from BS 5410:1:1997.
Notes:
For a boiler fitted in a compartment, which is
ventilated as shown, no additional allowance is
necessary.
Open flue - Extract fans, where needed, should
be in accordance with Section 4.4.7 in BS 5410
Part 1 1997.
All ventilation areas given are for domestic
applications. For all other cases refer to BS
5410 Part 2 1978.
Under no circumstances can Grant condensing
boilers be installed with existing flue systems. Only
flue systems and components suitable for wet flues
should be used.
Failure to install the correct type of flue system will
invalidate the warranty.
See Fig. 10a and 10b
General
Grant condensing boilers have high operating efficiencies
and low flue gas temperatures. Care must be taken to
ensure the flue system is suitable for the very low flue gas
temperatures and condensate in the flue gases.
Suitable conventional flue systems (Orange system)
are available from your local stockist - see Fig. 10a.
1 The flue must terminate in a down draught free area,
i.e. at least 600 mm above the point of exit through the
roof or preferably above the ridge level.
2 The condensate may be allowed to run back into
the boiler. A condensate drain at the base of the
flue system is not required.
3 The flue terminal must be at least 600 mm from
any opening into the building, and 600 mm above
any vertical structure or wall less than a horizontal
distance of 750 mm from the terminal. See Fig. 11.
4 If an existing chimney is to be used, it must be lined
with a smooth bore stainless steel liner suitable for
use with oil fired condensing boilers. The top and
bottom of the annular space must be sealed.
The internal flue and liner diameter for all models
must be 100 mm (4 in).
Conventional flue system
4.7
Grant recommends the use of the Grant 'Orange'
flue system, specifically designed for the
Euroflame range of condensing boilers. Refer to
Section 4.7 for further details.

5 Twin-wall flues are recommended for externally
run flues to reduce the possibility of the condensate
freezing in the flue.
6 No part of any flue system should be made of an
asbestos material; aluminium must not be used in
any part of the flue. Only stainless steel flue
components should be used.
7 If the draught conditions are satisfactory, the flue
should terminate with a standard cowl.
8 Refer to the locally applicable Building
Regulations, BS 5410:1 and OFTEC Installation
Requirements (Books 2 and 3) for further guidance
on conventional flue systems.
It is important to ensure that the flue system is sealed
and that condensate cannot escape. Up to 1.5 l/h of
condensate can be produced in a conventional flue
system.
Only use flue systems suitable for oil fired condensing
boilers.
Do not use fire cement. The use of high temperature
silicone sealants is recommended.

Apart from a conventional flue, several balanced flue
options are available for use with the Grant condensing
boilers. All are suitable for use with Class C2 kerosene.
Note: None of the flue sections in the following
system can be cut.
1 Low level horizontal balanced flue (Yellow system)
Available in Standard kits.
Extensions are available which extend the flue by
225 mm, 450 mm or 675 mm. 90° and 45° elbows
are also available.
The maximum flue length - from the centre of the
boiler flue outlet to the outer face of the wall - is 4
metres (with or without elbows included). No more
than 2 x 45° or 1 x 90° elbow should be fitted per
system.
2 High level (horizontal) balanced flue (White
system)
Allows the flue to rise vertically within the building
before exiting through the wall horizontally.
The maximum flue length - from the top of the
boiler flue outlet to the outer face of the wall - is 10
metres for all Euroflame condensing boilers.
Extensions are available which extend the flue by
225 mm, 450 mm or 950 mm. An adjustable
extension of 275 to 450 mm is also available.
A 45° elbow is also available. No more than 6 x 45°
elbows should be fitted per system. Each elbow reduces
the overall maximum length of the system by 1 metre.
3 Vertical balanced flue (White system)
Allows the flue to rise vertically from the boiler to
exit through the roof.
The maximum flue length - from the top of the
boiler flue outlet to the terminal - is 12 metres for
all Euroflame condensing boilers.
Extensions are available which extend the flue by
225 mm, 450 mm or 950 mm. An adjustable
extension of 275 to 450 mm is also available.
A 45° elbow is also available. No more than 6 x
45° elbows should be fitted per system. Each elbow
reduces the overall maximum length of the system
by 1 metre.
Balanced flue options
4.8
Where it is not possible to terminate the low level flue
at low level, a plume diverter kit is available for fitting
to the low level flue. The plume diverter kit diverts the
flue gases up and terminates at a higher level. When
fitting the plume diverter kit, follow the instructions
supplied with the kit. See Fig. 10b.
The minimum dimensions for locating the terminal
from building features (windows, doors, etc.) are
shown in Fig. 11.
If the flue terminal is fitted less than 2 metres above a
surface to which people have access, the terminal must
be protected by a guard. The guard must be fitted
centrally over the flue terminal and securely fixed to
the wall.
The low level balanced flue (Yellow system) is
supplied with a stainless steel guard. This must be
fitted in all circumstances to prevent objects from
entering the flue outlet.
The terminal must be positioned so as to avoid
products of combustion accumulating in stagnant
pockets around the buildings or entering into
buildings. Care should be taken that the plume from
condensed flue gases does not cause a nuisance.

Notes:1 An opening means an openable
element, such as an openable
window, or a permanent opening
such as a permanently open air vent.
2 Notwithstanding the dimensions
given, a terminal should be at least
300 mm from combustible material,
e.g. a window frame.
3 A way of providing protection of
combustible material would be to fit
a heat shield at least 750 mm wide.
Where the frost thermostat is installed outside the house (to
protect a boiler installed in an external boiler room or
garage) or in an attic, it is recommended that it be used in
conjunction with a pipe thermostat to avoid unnecessary and
wasteful overheating of the property. The pipe thermostat
should be located on the boiler return pipe, and set to operate
at 25° C. Refer to Section 10 for connection details.
For additional protection of either the entire heating
system, or the boiler and localised pipework, it is
recommended that a frost thermostat be installed.
Refer to Section 10 for connection details.
To protect the heating system, the frost thermostat
should be sited within the house in such a place that it
can detect any rise and fall in the ambient air
temperature, i.e. in a room with a radiator.
The Installer must ensure that the terminal does not cause
a nuisance.

Boiler location
4.10
1 The boiler must stand on a surface that is firm and
level. It does not require a special hearth as the
temperature of the boiler base is less than 50° C.
2 Sufficient clearance must be allowed at the front of the
boiler to remove the burner and baffles for servicing.
3 Once the boiler has been installed, a permanent
worktop may be fitted over it as access to the top
of the boiler is no longer required after installation.
Sealed system kit fitted - A removable section of
worktop above the boiler is required to provide
access for servicing.
Water connections - all models See Fig. 12
4.11
IMPORTANT: Ensure that the flow pipe is vented at its highest point in the system.
All models
To avoid the danger of dirt and foreign matter entering the boiler the complete heating system should be thoroughly
flushed out - before the boiler is connected and then again after the system has been heated and is still hot. This is
especially important where the boiler is used on an old system.
For optimum performance after installation, this boiler and its associated central heating system must be flushed in accordance with the
guidelines given in BS 7593:1992 'Treatment of water in domestic hot water central heating systems'.
For Long term protection against corrosion and scale, after flushing, it is recommended that an inhibitor such as
Betzdearborn's Sentinel X100 or Fernox MB-1 is dosed in accordance with the guidelines given in BS 7593:1992.
Failure to implement the guidelines will invalidate the warranty.
A drain cock is fitted at the bottom on the front of the boiler to allow the heating system to be drained

6 Provision should be made to replace water lost
from the system. This can be done manually (where
allowed by the local water undertaking) using an
approved filling loop arrangement incorporating a
double check valve assembly.
7 An automatic air vent should be fitted to the
highest point of the system, as the air vent in the
boiler is for venting the boiler only.
8 The system design pressure (cold) should be between
0.5 and 1.0 bar. This pressure is equivalent to the
maximum static head in bar + 0.3 (1 bar = 10.2 metres
of water).
9 All fittings used in the system must be able to
withstand pressures up to 3 bar.
10 Radiator valves must comply with the requirements
of BS 2767(10):1972.
11 One or more drain taps (to BS 2879) must be used
to allow the system to be completely drained.
12 For proprietary expansion vessel/valve/gauge
packs, refer to the manufacturers instructions for
the correct location on the heating system.
1 A 15 mm discharge pipe must be connected to the
safety valve outlet connection. The pipework between
the safety valve and the boiler must be unrestricted,
i.e. no valves. The discharge pipe should be run to the
outside of the building and terminate so that it cannot
cause injury to persons or property.
2 A 15 mm double check valve ballofix type valve is
provided on the flexible filling loop hose for
connection of the cold mains supply to the heating
system. The cold mains supply should terminate
inside the boiler casing.
3 The expansion vessel is connected via a flexible
hose to allow it to be moved to gain access to the
baffle cleaning cover. When replacing the vessel,
care should be taken to ensure that the flexible
connecting hose is not twisted.
On underfloor systems it is essential that the return
temperature must be maintained above 40° C to
prevent internal corrosion of the boiler water jacket.
General - Grant boilers are compatible with both
copper and plastic pipe. Where plastic pipe is used it
must be of the oxygen barrier type and be of the
correct class (to BS 7291:Part 1:1990) for the
application concerned.
IMPORTANT: The first metre of pipework
connected to both the heating flow and return
connections of the boiler must be made in copper on
all types of system - sealed or open-vented.
Sealed systems - If plastic pipe is to be used, the

4 - GENERAL BOILER INFORMATION
When in condensing mode the Grant Euroflame
condensing boilers produce condensate from the water
vapour in the flue gases. This condensate is slightly
acidic with a ph value of around 3 (similar to vinegar).
Provision must be made for the safe and effective
disposal of this condensate.
Condensate can be disposed of using one of the
following methods of connection:
Internal connection (preferred option)
• into an internal domestic waste system (from
kitchen sink, washing machine, etc.)
• directly into the soil stack
External connection
• into an external soil stack
• into an external drain or gulley
• into a rainwater hopper (that is part of a combined
system where sewer carries both rainwater and foul
water)
• purpose made soakaway
All condensate disposal pipes MUST be fitted with a
trap - whether they are connected internally or
externally to a domestic waste system/soil stack or run
externally to a gulley, hopper or soakaway.
General requirements
5.1
Connections into a rainwater hopper, external drain or
gulley should be terminated inside the hopper/drain/
gulley below the grid level but above the water level.
Condensate disposal pipes should not be connected
directly into rainwater downpipes or to waste/soil
systems connected to septic tanks.
Condensate should not be discharged into 'grey water'
systems that re-use water used in the home (not
including water from toilets).
It should be noted that connection of a condensate pipe
to the drain may be subject to local Building Control
requirements.
Condensate disposal pipework must be plastic (plastic
waste or overflow pipe is suitable).
IMPORTANT: Copper or steel pipe is NOT suitable
and MUST NOT be used.
Condensate disposal pipes should have a minimum
'nominal' diameter of 22 mm (¾") - e.g. use 21.5 mm
OD polypropylene overflow pipe.
Condensate disposal pipes must be fitted with a fall
(away from the boiler) of at least 2.5° (~45 mm fall
per metre run).
Connections

Pipework
5.3
5 - CONDENSATE DISPOSAL
Underfloor systems - Plastic pipe may be used on
Underfloor systems where the plastic pipe is fitted
after the thermostatic mixing valve. Copper tube must
be used for at least the first metre of flow and return
primary pipework between the boiler and the
underfloor mixing/blending valves.
Page 26

Grant Euroflame condensing Indoor/Utility and Boiler House Oil Boilers
Note: Where it is not possible for the pipe to fall
towards the point of discharge - either internally into a
waste system or externally to a gulley (e.g. for boilers
installed in a basement), it will be necessary to use a
condensate pump.
Condensate disposal pipes should be kept as short as
possible and the number of bends kept to a minimum.
Pipes should be adequately fixed to prevent sagging,
i.e. at no more than 0.5 metre intervals.
External pipework
Ideally, external pipework, or pipework in unheated
areas, should be avoided. If unavoidable, external
pipework should be kept as short as possible (less than
3 metres) and 32 mm waste pipe used to minimise the
risk of ice blocking the pipe in freezing conditions.
The number of bends, fittings and joints on external
pipes should be kept to a minimum to reduce the risk
of trapping condensate.
Note: For boiler installed in an unheated area such as
an outhouse or garage, all condensate pipework should
be considered as an ‘external’.
5 - CONDENSATE DISPOSAL
To keep external pipework to a minimum, locate the
soakaway as close as possible to the boiler but ensure
it is at least 1 metre from building foundations and
away from other services, e.g. gas, electricity, etc.
The condensate pipe may be run above or below
ground level and can enter either the top or side of the
soakaway tube. Refer to Fig. 14.
Ensure that the drainage holes in the soakaway tube
face away from the building.
Backfill both the soakaway tube, and the hole around
it, with 10 mm limestone chippings.
Only use a soakaway where the soil is porous and
drains easily. Do not use in clay soils or where the
soil is poorly drained.
WARNING: Any damage due to condensate backing
up into the boiler due to a high water table, in the case
of a soakaway, or flooded drains when the condensate
disposal is via a gulley or soil stack, is not covered by
the Grant product warranty.

Condensate trap
5.5
If there is any discharge of condensate from the overflow
outlet, this could indicate a blockage (possibly due to
freezing). Turn off the boiler and investigate the cause. If
necessary contact your service engineer for assistance.
Care should be taken when siting the trap such that the
overflow outlet is readily visible and that any
condensate overflowing from the outlet cannot cause
either a hazard to persons or damage to surrounding
property or equipment.
The condensate trap outlet is at an angle of 48° below
the horizontal. This is to automatically give a 3° fall on
any 'horizontal' runs of condensate disposal pipe. Refer
to Fig. 15.
The outlet of the trap will accept 21.5 mm to 23 mm
OD Polypropylene overflow pipe for the condensate
discharge pipe.
This discharge pipe can exit through the left hand side
of the boiler through one of pre-cut 'knock-outs' in the
casing panel (see to Fig. 1). Push out the 'knock-out'
from the required hole taking care not to distort the
side panel.
The trap MUST be checked at regular intervals (e.g.
on every annual service) and cleaned as necessary to
ensure that it is clear and able to operate.
Note: The bottom bowl is sealed to the trap body and
cannot be removed.
Fig. 15 - Condensate trap )Indoor/Utility models)
Grant Euroflame condensing Indoor/Utility boilers are
supplied with a factory-fitted condensate trap to provide the
required 75 mm water seal in the condensate discharge pipe
from the boiler.
The condensate trap for the Boiler House models is
supplied loose in the burner box and needs to be fitted as
shown in Fig. 15a.
This trap incorporates a float (which will create a seal
when the trap is empty) and an overflow warning
outlet (fitted with a plastic sealing cap), See Fig. 15.
On Indoor/Utility models the trap is factory-fitted
inside the boiler casing (mounted on the inside of the
left side panel) in an accessible position to allow for
routine maintenance.
Note: If required, this condensate trap may be re-located
outside the boiler casing. Refer to procedure given in
'external condensate trap'. This procedure MUST be
carried out before the boiler is installed.
A flexible hose connects the outlet of the condensing
heat exchanger to the trap inlet. Ensure the straight
connector on the hose is fully pushed onto the 'top hat'
inlet connector of the trap.
With the trap fitted inside the boiler casing, the sealing
cap MUST be fitted. If the trap is re-located outside
the boiler then the following applies:
If connecting the condensate discharge (either internally
or externally) into a waste system or soil stack - the
sealing cap MUST be fitted in the trap outlet.
On external discharge systems to a hopper, gulley or
soakaway, the sealing cap should be removed from the
trap outlet.

4 Push out pre-cut 'knock-out' from the condensate
outlet hole in the rear of left side casing panel.
5 Remove the right angle end of the flexible
condensate discharge hose from the outlet
connection on the condensing heat exchanger.
6 From the front of boiler, remove the straight
connector end of the flexible hose from the top of
the condensate trap.
7 Reverse the flexible hose and pass the straight
connector end through the new hole in the left hand
casing panel. Push the straight connector firmly onto
the condensate outlet connection of the condensing
heat exchanger - push on at least 20 mm.
8 Refit the left hand casing panel to the rear panel
using the reverse procedure, ensuring all fixing
screws are used.
9 Remove the trap from the mounting bracket.
10 Unscrew and remove the trap mounting bracket
from the left side panel.
11 Fix the trap mounting bracket to the wall adjacent
to the boiler in the required position.
Note: The top of the trap must be below the
condensate connection on the boiler.
12 Re-fit the trap to the mounting bracket.
The mounting bracket supplied with the trap
MUST be used - the trap should NOT be
supported by the condensate pipework only.
13 Connect the flexible condensate hose to the trap,
pushing the right angle hose connector onto the
trap inlet connection.
IMPORTANT: The flexible hose must fall
continuously from the outlet to the top of the trap.

Indoor/Utility models are supplied with the burner
fitted. To fit the burner to a Boiler House model
proceed as follows:
1 Remove and retain the burner fixing nut from the stud
on the burner mounting flange on the front of the
boiler, see Fig. 20. Leave the small nut in position
(ensure it is located up against the mounting flange).
Note: Do not remove the mounting flange from the
boiler.
2 Check that the 'O' ring is in position (around the collar
of the burner combustion head). Position the burner
on the boiler by sliding the combustion head into the
mounting flange on the boiler. With the burner level
and correctly located over the fixing stud, secure it in
position using the nut previously removed.
3 Balanced flue - Fit the air tube over the air tube spigot
and secure in position using the clamp supplied.
See Fig. 7
If a two pipe system is to be used refer to Section 4.4.6.
1 Remove the oil inlet plug from the fuel pump and
connect the elbow of the flexible fuel hose supplied
with the boiler.
2 Connect the flexible fuel hose to the rigid supply
using the adaptor supplied. The supply enters
through one of the holes in the casing plinth.
1 Automatic air vent(s) are fitted to the top of the
boiler. Check that the small cap on the top of each
air vent is screwed on fully, then unscrew it one
complete turn - the cap remains in this position
from now on.
2 If the flexible filling loop is used to fill the system, ensure
it is connected and that the valve connecting it to the
boiler is open and the valve at the front is closed.
A valve is open when the operating lever is in line with
the valve, and closed when it is at right angles to it.
3 Ensure that the mains cold water supply valve is open
(operating lever in line with the valve), then turn on the
mains cold water supply and gradually open the front
valve on the filling loop until water is heard to flow.
4 Vent each radiator in turn, starting with the lowest
one in the system, to remove air.
5 It is important that the pump is properly vented to
avoid it running dry and damaging its bearings. To
gain access to the pump for venting it is necessary
to remove the control panel.
Loosen the four fixing screws securing the panel to the
casing, push the panel towards the rear of the boiler and
lower the control panel to expose the pump.
Remove the cap, then unscrew and remove the plug
from the centre of the pump. Using a suitable
screwdriver rotate the exposed spindle about one
turn. Replace the plug and cap.
6 Check the operation of the safety valve by turning
the head anticlockwise until it clicks. The click is
the safety valve head lifting off its seat allowing
water to escape from the system.
Check that this is actually happening.
7 Continue to fill the system until the pressure gauge
indicates between 0.5 and 1.0 bar. Close the fill point
valve and check the system for water soundness,
rectifying where necessary. Water may be released
from the system by manually operating the safety
valve until the system design pressure is obtained.
8 The system design pressure (cold) should be
between 0.5 bar and 1.0 bar. The pressure is
equivalent to the maximum static head in bar + 0.3
(1 bar = 10.2 metres of water), where the static
head is the vertical height from the centre of the
expansion vessel to the highest point of the system.
9 Close the valves either side of the filling loop and
disconnect the loop.

7 - COMMISSIONING
It is important that the following commissioning
procedure is carried out to ensure safe and efficient
operation of the boiler.
Note: Check that the baffles are in position and that the
refractory base (insulation) is correctly located in the
base of the combustion chamber. Check that the cleaning
cover is correctly fitted and a good seal made.
IMPORTANT:
Check that the turbulators are in position and that
the ends are vertical (see Fig. 25).
Notes: 1. If the 50/70 model is down rated to 15 kW,
the burner air adjuster disc must also be
adjusted to setting B as described overleaf.
See Section 3.3.
2. If the 70/90 model is down rated to 21 kW,
the burner head must also be changed to a
T1 head. See Section 3.3.
1 Check that both the boiler overheat and boiler control
thermostat bulbs are correctly located in their
respective pockets. For location of thermostat pockets,
refer to Fig. 12. Also check the condition of both
thermostat capillaries, i.e. that they are not damaged,
broken or kinked, and that they are not trapped or
crushed between any internal boiler components.
2 Check that the water system has been vented (and
pressurised if sealed system) and there are no leaks.
Ensure the flow pipe has been vented.
3 Check that all fuel line valves are open.
4 Remove the plastic burner cover if it was not
previously removed.
5 Connect a combined vent manifold and pressure
gauge to the pressure gauge connection port on the oil
pump. See Fig. 7. Open the vent screw on your vent
manifold to vent the supply while the pump is running.
6 Set the On/Off switch to Off. Check that all system
controls are calling for heat and turn the boiler thermostat
to maximum. Switch on the electricity supply.
7 Set the On/Off switch to On. The burner fan should
start and the burner should light within about 12
seconds. If the burner does not light and the 'Lockout' reset button lights, wait for about 45 seconds
then press the reset button to restart the ignition
process. This procedure may have to be repeated
several times during first lighting.
8 With the burner alight, check the fuel pressure. Refer
to the Technical Information, Section 3.3. Adjust the
pressure if necessary - see Fig. 7. Note that the 'Mains
On' neon lights when the boiler is switched on, but
does not necessarily indicate the burner is firing
(Indoor/Utility models only).
9 Operate the boiler until it reaches normal operating
temperature. Check oil supply/return pipe for leaks,
rectifying where necessary.
10 Check the operation of the boiler thermostat. Ensure that
by turning it anticlockwise it switches the burner off.
11 With the burner alight, re-check the fuel pressure and
re-adjust if necessary. Turn the boiler off, remove the
pressure gauge and replace the plug in the pump.
12 Having ensured that there are no oil leaks, replace the
burner cover. Ensure the flexible air tube is connected
to the burner (balanced flue models).
13 Relight the boiler and allow it to run for at least 20
minutes.
14 Check the smoke number, if satisfactory check the
CO2. Set the CO2 to the value given in Section 3.3
for the boiler concerned.
Use the hexagonal key supplied to adjust the
burner air damper (see Fig. 20) as required.
Turning the screw anti-clockwise closes the
damper and increases CO2 level, turning the screw
clockwise opens the damper and reduces CO2 level.
Re-check the smoke number if the damper has been
moved. Under no circumstances must the smoke
number be above 1.
Note: It is important that the air damper is
correctly set.
15 Check the flue gas temperature.
16 Replace the case top on the Indoor/Utility models or
the side blanking plate on the Boiler House models.
17 When the boiler has been adjusted and is running
satisfactorily, balance the central heating system by
adjusting the radiator lock shield valves. Start with
the radiator nearest the boiler and adjust the valves
to achieve the required temperature drop across
each radiator. If thermostatic radiator valves have
been installed, check the system by-pass.
18 Switch off the boiler.
19 With the system hot, check again for leaks,
rectifying where necessary. Drain the system while
it is hot to complete the flushing process. Refill and
vent (and pressurise if a sealed system) the system.
20 A suitable central heating system inhibitor must be
added to protect the system against the effect of corrosion.
21 Indoor/Utility models - Replace the front panel. Locate
the bottom of the panel over the fixing tags then push
it towards the boiler to engage the fixing clips.
Note: After commissioning the boiler complete the
boiler passport that comes supplied with this boiler
and return the commissioning details to Grant

If the boiler is to be left in service with the User, set the
system controls to the User's requirements.
If the boiler is not to be handed over immediately,
close the boiler fuel supply valve and switch off the
electricity supply.
If there is any possibility of the boiler being left during frost
conditions, then the boiler and system should be drained.
IMPORTANT NOTE:
To allow the boiler to be commissioned and serviced
correctly a combustion test point is provided on the front
cleaning door.
The CO2 and smoke test may all be carried out using this
test point. The test point is not suitable for measuring
boiler efficiency or conventional flue draught.
When using the test point on the cleaning cover note that the
flue gas temperature reading will be higher than that measured
in the flue thus resulting in an inaccurate efficiency reading.
To obtain an accurate flue gas temperature and efficiency,
the reading can only be measured outside through the low
level flue terminal. For high level and vertical balanced flues
the reading may be taken from the flue kit test point
provided. Refer to Section 3.3.
For Conventional flue draught measurement and efficiency
a test point is provided in the conventional flue adaptor.
To adjust the 50/70 air adjuster disc when
downrating - See Fig. 22
