Dual Thermostat
The radiator temperature is regulated via the
boiler control thermostat. The thermostat is user
adjustable from 55°C at its minimum setting (dial
‘0’) to 85°C at its maximum setting (dial ‘5’). In
order to provide an additional level of safety there
is a high limit thermostat which has a cut off point
of 110°C; this is factory set and is not adjustable.
If thermostat trips it needs to be reset manually.

System
When the boiler is connected to a sealed system
the system pressure should be periodically
checked. The minimum pressure, as indicated by
the black needle, is 0.5 bar when the boiler is cold
and 2.5 bar when the boiler is at normal operating
temperature. If the pressure is outside this range
contact Warmflow or your installer.

Filling Loop
If the system pressure falls below the minimum
(eg, removal of radiator for decorating purposes)
then the system should be topped up using the
filling loop valve. After the system has been topped
up the pressure gauge should read 1 bar when
the system is cold. The valve must be fully closed
and the filling loop flexible removed from the valve,
expect a small water loss from the pipe.

In the event of a breakdown please contact your commissioning engineer
who should then contact our service department whilst at your home, to
report the fault.
Page CONDENSING BOILER INSTALLATION
REQUIREMENTS
The Warmflow condensing boiler can be fitted to most installations using
standard practices and techniques.
There are however a number of considerations that must be taken into
account.
1.
All existing systems must be properly flushed to remove any sediment/
sludge in order to prevent any blockage or reduction in efficiency of the
boiler.
2.
The system must be fully pumped.
3.
The primary difference between an ordinary boiler and a condensing
boiler is the condensate drain. The drain can be plumbed from the
condensate trap in any ordinary plastic pipe, eg, plastic overflow pipe,
directly into the household drain or soak away.
Any blockage in the drain could lead to an alteration in the combustion
settings because of partially blocked flueways.
Where the boiler is fitted into a basement a condensate pump may be
required.
4.
As an indicator of the increased efficiency of a condensing boiler there
may be a visible plume of ‘steam’ from the flue. Care needs to be
exercised when positioning the appliance and selecting the type of flue
to ensure that the plume does not cause a nuisance to the householder
or to surrounding properties.
As the water temperature in the system rises the pluming effect will
diminish. Even where pluming is not visible the boiler is still operating
more efficiently than a standard boiler.
Page BEFORE FITTING A COMBI BOILER
THE INSTALLER MUST CHECK:
1.
What the maximum hot water demand placed on the boiler is likely
to be. Not every installation is suitable for a Combi boiler. Systems
requiring very high hot water flow rates may be better suited with an
unvented cylinder.
2.
That the mains are capable of supplying up to 24 litre/min with a
minimum dynamic pressure of 1.8 bar at the boiler. This is to ensure that
the boiler can achieve its maximum output. To protect the appliance
and to prevent excessive flow rates, a pressure reducing valve must be
fitted to limit the maximum supply pressure to 3 bar.
3.
Where the mains water pressure is supplied via a borehole pump and
accumulator the pressure variation must not affect the thermostatic
mixer valve. Contact Warmflow for further details.
4.
The hardness of the mains water supply. Systems with hard water must
be fitted with a suitable chemical scale preventer (eg Fernox Quantomat
or Combimate).
5.
That the flow from any one hot water outlet does not exceed the
maximum recommended. This applies particularly to baths which are
usually fitted with larger taps and larger bore supply pipes. It may be
necessary to restrict the flow to these taps by reducing the bore of the
supply pipework (eg 15mm) or by fitting a restrictor into the pipework.
6.
That any outlet when opened does not starve all the other outlets of hot
water. If more than one outlet is open at the same time then the total
flow from all the outlets should not exceed the maximum flow rate of
the boiler.
7.
That any showers being supplied with hot water by the boiler are
compatible with this type of appliance.
It should be noted that the boiler has been factory fitted with an
18 litre/min flow restrictor.
The manufacturer’s guarantees are void if the appliance is not installed
and commissioned in accordance with the recommendations made
herein.

General Information
1.1
Introduction
Note: All our domestic appliances have been independently tested and
accredited as exceeding the minimum SEDBUK efficiency levels required for
their type, in compliance with the Building Regulations Approved Document
L1A, L1B for England and Wales, the Building Standards (Scotland)
Regulations Section 6, Part F Northern Ireland and Part L Republic of
Ireland.
Warmflow oil fired condensing boilers are designed to burn Class C2 (28 sec
redwood) kerosene only and to be used on a fully pumped system, and are suitable
for connection to sealed heating systems.
As standard the Combi and System boilers are fitted with a system expansion
vessel, circulating pumps, filling loop, pressure gauge and safety valve. An optional
7-day electronic programmer kit is also available for all Utility boiler models.
The Combi can provide at mains pressure domestic hot water without the need for
a storage cylinder.
The manufacturer’s guarantees are void if the appliance is not installed and
commissioned in accordance with the recommendations made herein.
1.2
General Requirements
The installation of the boiler must be in accordance with the following regulations.
BS5410 : PART 1 Code of practice for oil firing.
BS5449 : PART 1 Forced circulation hot water systems.
BS7593 : Treatment of water in domestic hot water central heating systems.
Current Building Regulations:
Part J England and Wales
Section 3 Scotland
Part L Northern Ireland
Part J Republic of Ireland
Current IEE Regulations
BS7074 : PART 1 Application Selection & Installation of Expansion Vessels
The heating system should be installed by a competent installer in accordance with
the recommendations laid down by HVCA, OFTEC and sound engineering practice.
In order to comply with building regulations OFTEC forms CD10 for

Combi General Requirements
The boiler will have a DHW priority when both domestic hot water (DHW) and central
heating (CH) are selected. So if the flow switch is closed or the heat store has not
been satisfied the entire output of the boiler is directed to DHW before the boiler will
switch over to CH. When fully cold it can take up to 20 minutes for the heat store of
a 90,000 Btu/h combi to be satisfied, and slightly longer for a 70,000 Btu/h combi.
After a draw-off of 120L at 24L/min, with an average temperature rise of 32ºC,
the thermal store of a 90,000 Btu/h combi has a recovery time of approximately
7 minutes. A 70,000 Btu/h combi will take slightly longer to recover.
Note: If HW has not been selected no hot water can be produced even if the heat
store is up to temperature.
1.3.1 Pump Overrun
Where there is a build up of excess heat in the boiler primary heat exchanger
and the central heating has not been selected then the pump overrun thermostat
will operate. The excess heat will then be pumped into the heat store. Once the
temperature has fallen in the boiler and the pump overrun stat is satisfied, then the
hot water pump will stop.
Page Page Models up to 120 HE
The primary heat exchanger baffles consist of one
heavy baffle stack (4mm thick) at the bottom, 3
lighter baffle stacks (3mm thick) in the middle and 1
baffle plate (3mm thick) at the top. Upon installation
or after servicing, ensure the baffles are in the correct
order and correctly stacked. To achieve maximum
efficiency push the primary heat exchanger baffles in
the direction of the arrows as shown. The secondary
heat exchanger spring baffles must be fully inserted
into the heat exchanger tubes (narrow end first).
Baffle Positioning
1.4
The primary heat exchanger baffles consist of two
half-width baffle stacks at the bottom, 3 full-width
baffle stacks in the middle and 1 baffle plate at the
top. Upon installation or after servicing, ensure the
baffles are in the correct order and correctly stacked.
To achieve maximum efficiency, push the primary
heat exchanger baffles in the direction of the arrows
as shown. The secondary heat exchanger spring
baffles must be fully inserted into the heat exchanger

Note:
1. All flues can utilise any combination of bends, straights, adaptors and terminals.
2. Ensure flue is arranged such that it falls continuously towards the boiler.
3. The Low Level, High Level and Vertical Balanced Flue Systems can use any combination of
flue extension pieces up to the maximum equivalent length depending upon boiler output as
illustrated in the above table.

2.4
Condensate Disposal
The Warmflow high efficiency condensing boiler is supplied with a factory fitted, self
sealing condensate trap. The trap has been fitted inside the boiler casing to the right
hand side.
The condensate drainage pipe within the boiler is a flexible plastic hose which can
be trimmed to length. 3/4” or 22mm pipe should be connected to the flexible hose.
The pipe should not be made from steel or copper. The drainage pipe may run
into an internal soil stack or waste pipe, an external gulley, hopper or soakaway as
shown below.
The boiler when fully condensing will produce a maximum of 1.5 litres per hour of
condensate. It is recommended that the drainage pipe should have a minimum fall
of 1:20.

In order to provide frost protection for the fabric of the building a frost thermostat
should be fitted in the coldest room in the house. To prevent over heating of the
property a pipe thermostat should be fitted on the return pipe close to the boiler.
The Kabin Pak Combi boiler is factory fitted with a frost thermostat as standard.
3.3.5 Combi Pump Overrun Thermostat
The condensing Combi boilers have been fitted with a pump overrun thermostat.
In order for the thermostat to work effectively the boiler must be supplied with a
permanent live. Failure to do this will result in nuisance trip outs.

Oil Supply
1.
Oil Tank
Steel tanks constructed to BS799 : PART 5 should be painted on the outside only
and mounted on piers to prevent corrosion. Plastic oil tanks are also available and
can be suitable for installation at ground level. However, oil should never be stored in
translucent plastic containers.
The tank outlet should be at a height to provide sufficient clearance to allow for
proper maintenance of any isolation valve, oil filter or water separator fitted.
2.
The pipe from the oil tank to the burner should be run in copper, steel or aluminium.
Galvanised pipe and fittings should not be used. The pipework should terminate
close to the boiler and be fitted with an isolating valve and filter. A remote sensing
fire valve must be fitted to the oil line preferably before the oil line enters the building
(BS5410 : PART 1).
Depending on the position of the tank a two pipe system may be required. One and
two pipe oil systems are shown below. As an alternative to a two pipe system a
Tigerloop or other approved de-aerator may be used.

Installation of Flues
Page 49
5.1.1 Installation of a Balanced Flue (FBF)
1.
Make a suitable sized hole in the wall or ceiling for the flue. For the dimensions of
the boiler, see the Dimensions Section of this manual. For the dimensions of the flue
system, see the Flue Kits & Dimensions Section of this manual.
Note: The cavities around the opening must be sealed and protected by a noncombustible sleeve.
2.
Remove the top casing panel. If fitting a low level horizontal flue (FBF), remove the
upper casing panel knockout from the appropriate side or rear panel using a pair
of tin snips. Push the boiler into position against the wall then install the flue starter
piece, securing it in position using the nuts provided and ensuring the black rubber
gasket is correctly seated. The white fibre gasket supplied in the Flue Fittings Kit
(FFK) is not required and should NOT be fitted.
3.
If installing extension pieces, ensure the seals are correctly fitted and lubricated
before pushing through the wall and into the starter piece.
Note: Refer to the Flue Options, Components and Dimensions Section for details of
the maximum number of extension pieces and total flue lengths allowed.
4.
If installing a vertical flue, correctly fit the flashing kit then slide the flue terminal into
position with a twisting movement. Ensure that the terminal protrudes through the
roof by a minimum of 665mm.
If installing a horizontal flue, slide the flue terminal into position with a twisting
movement then seal the gap between the flue and the wall both inside and outside.
Ensure that the terminal protrudes through the wall by a minimum of 175mm and a
maximum of 225mm.
If installing a Plume Management Kit, fit the starter piece and horizontal terminal as
described above then install the Plume Management Kit as instructed in the leaflet
supplied with the kit.”
5.
If installing a low-level horizontal flue, fit the terminal guard (basket) over the flue
terminal using the cardboard mounting template supplied with the flue kit to locate
and drill the necessary screw holes in the wall.
6.
Remove the air inlet cover from the burner then fit the intake adaptor spigot and
gasket. Connect one end of the air duct / hose to the flue and the other end to the
adaptor spigot and secure.
Page 50
5.2
Conventional Flues
The flue system should be designed in accordance with local
bye-laws and the Building Regulations. Draught stabilisers
are not recommended for oil fired boilers. Sharp bends
or horizontal runs should be avoided and the flue should
terminate 2 feet (600mm) above the ridge of the dwelling.
Terminals which restrict the discharge or allow ingress of
water should be avoided.
When connecting to an existing masonry chimney, a flexible
flue liner suitable for use with oil fired condensing boilers and
of an appropriate diameter must be used. The annular space
must be filled with insulation and sealed top and bottom.
The starter piece should be sealed into the conventional
flue adaptor using a high temperature silicone sealant, fire
cement must not be used.
Only proprietary flue systems designed specifically
for use with oil-fired condensing boilers may be used.
The flue system manufacturer’s installation instruction
must be followed.
For recommended conventional flue systems, contact
Warmflow.
5.3
Low Level Balanced Flue Terminal Positions
Attention should be given to the position of the flue discharge;
we recommend the following guidelines be adopted.
1.
The flue should not discharge beneath opening windows or
near other accesses to the building.
2.
The flue should not discharge near internal/external corners
of the building where turbulent wind conditions could occur.
3.
A terminal guard must be fitted at all times.
4.
The terminal should not discharge over property boundaries.
5.
Discharge into narrow passageways should be avoided.
6.
The location of the terminal and routing of the flue should
be determined by the installer after consultation with the
householder.
7.
In positioning the flue the wind direction should be
considered.
Installation in exposed positions is not recommended.
8.
Account must be made of the pluming from the flue. If it is
likely to be a nuisance to the householder the use of a vertical
balanced flue or conventional flue should be considered.

Installation Requirements
The boiler installation must be in compliance with BS5410 : PART 1 and the Building
Regulations.
7.1
General Requirements
7.1.1 Hearth
The boiler has a hearth temperature of between 50°C and 85°C and should be stood
on a rigid, non-porous, non-combustible base, which is not softened by warmth, to
comply with the Building Regulations.
7.1.2 Service Access
24” (600mm) Clearance should be provided above and in front of the boiler to allow
for routine servicing. Pumped, System and Combi models may require access to
the top.
7.1.3 Heating System
The heating system should be installed to HVCA current codes of practice. Before
installing the boiler the new or existing system must be thoroughly flushed to clear
all sludge or other foreign matter such as solder, steel wool and copper filings. The
system must be cleansed, neutralised and protected from corrosion in accordance
with BS5449 and BS7593 using suitable cleansing agent(s) and inhibitor(s) and
carried out in accordance with the cleanser / inhibitor manufacturers’ instructions.
The system must be dosed to the concentrations specified by the inhibitor
manufacturer (refer to the Technical Data section of this manual for the volume of the
boiler when calculating the total system volume). Failure of components such as, but
not limited to, pumps, auto air vents, pressure relief valves, plate heat exchangers
and non-return valves due to corrosion product in the system will not be covered by
warranty.
7.1.4 Air Vents
The plastic plugs of the auto air vent(s) factory-fitted to the boiler must be loosened
when filling the system in order to bleed the air from the boiler. In addition to any
factory fitted air vents it is recommended that another air vent is fitted at the highest
point in the system. Where the flow pipework drops down from the boiler the installer
must ensure that an automatic air vent is fitted to the top of the pipework to prevent
air being trapped in the boiler.
7.1.5 Drain Cock
For all appliances not factory-fitted with drain cocks, one should be fitted to the
boiler drain boss located to the left hand side of the burner. Drain cocks should also
be fitted to the lowest points in the system to allow the system to be completely
drained.
7.1.6 Frost Protection
Where there is a risk to the boiler or installation from frost then a suitable frost
thermostat should be fitted. Alternatively the system could be dosed with an anti
freeze agent. The Kabin Pak Combi boiler is factory fitted with a frost thermostat as
standard. For all other Kabin Pak models covered by this manual a Frost Thermostat
Kit (Code FSK1) is available as an optional extra.
7.1.7 Pipework
We strongly advise that all installation pipework is run in copper. However, if plastic
pipe is used, it must be recommended by the pipe manufacturer for use with oil fired
appliances and, in any case, the last 1000mm of pipework connected directly to the
appliance must be of copper. All connections to the appliance must be made with
compression fittings.
Page 54
7.2 Sealed Systems
7.2.1 Expansion Vessel
Refer to BS7074: PART 1 and BS5449 for details of expansion vessel sizing. The
values given in the table below are for total system volumes which include the
primary water capacity of the boiler which can be found in the Technical Data section
of this manual. System and Combi models up to 120HE are supplied with a 12 litre
expansion vessel charged to 1.0 bar. This can accommodate a maximum combined
boiler and system volume of 110 litres. Where permitted by the type, size and
configuration of heating system the expansion vessel bladder pre-charge pressure
can be reduced, prior to filling the system, to 0.5 bar in order to accommodate
a total system volume of 145 litres. If these maximum total system volumes are
exceed, additional expansion capacity will be required.

Total System
Volume
When measuring the expansion vessel bladder pre-charge pressure, using a tyre
gauge, the system should be cold and the system pressure should be relieved (by
manually operating the system pressure relief valve) in order to obtain an accurate
reading.
7.2.2 System Filling
For all System and Combi boilers a filling point complete with a filling loop is supplied
fitted to the expansion vessel. The filling loop must be disconnected from the mains
supply after filling. A system pressure when cold of 1 bar is recommended. After
filling, vent all air from the system. The plastic plugs of the auto air vent(s) factoryfitted to the boiler must be loosened when filling the system in order to bleed the air
from the boiler.
7.2.3 System Pressure
Water loss from the system as indicated by a reduction in pressure on the pressure
gauge may be made up through the filling loop. In the first week of operation it is
normal to see a drop in system pressure. After this time the system pressure must
be rechecked and the system refilled. Failure to do so may lead to boiler faults.
7.2.4 Pressure Relief Valve
Any pressure relief valve fitted to the boiler or system must be able to discharge
externally to a drain where the discharge can be seen but cannot cause any injury
or damage. No other valves should be positioned between the relief valve and
discharge termination.
7.2.5 Low Pressure Switch
Where there is a catastrophic loss of water from the system the boiler thermostats
may fail to operate which would result in serious damage to the appliance. To
prevent this it is recommended that a low pressure cut out switch set at 0.2 bar is
fitted to the system and wired in series with the boiler limit thermostat.
Page 55
7.3
Combi Domestic Hot Water
7.3.1 Mains Water Pressure
To protect the appliance and to prevent excessive flow rates, a pressure reducing
valve must be fitted to limit the maximum supply pressure to 3 bar. We strongly
advise that all installation pipework is run in copper. However, if plastic pipe is used,
it must be recommended by the pipe manufacturer for use with oil fired appliances
and, in any case, the last 1000mm of pipework connected directly to the appliance
must be of copper. Whenever a pressure reducing valve or other device containing
a non-return valve is fitted to the mains water supply entering the boiler, a mini
expansion vessel must be fitted after the device in order to protect the appliance
from the expansion due to heating of the water in the domestic hot water pipework.
Note that the flow rate from individual taps is dependant on the number of outlets
being operated together, as well as the length and size of pipework and the mains
supply pressure.
7.3.2 Water Hardness
Although many of the DHW components are designed to resist lime scale formation,
in areas of hard water it may still be necessary to fit an inline chemical water softener.
For further information contact Warmflow and your local water company.
7.3.4 Flow Restrictor
An 18L/min flow restrictor has
been factory fitted but can be
easily removed if required.
FLOW SWITCH
FLOW RESTRICTOR
WASHER
7.3.5 Boreholes
Where the mains water supply to the boiler is fed from a borehole via a pump and
accumulator arrangement the variable pressure can cause the mixer valve to go to
its fail safe settings thus preventing the outlet water temperature from achieving a
suitable level. In order to minimise the pressure variations it is recommended that
differential on the borehole pump pressure switch is kept as low as possible without
adversely affecting the pump motor. The accumulator must be as large as possible
in order to reduce the rate of pressure change and a pressure reducing valve (PRV)
must be situated between the pump and accumulator and the boiler. The PRV must
be set slightly below the minimum setting of the pressure switch on the pump.

Air Damper Adjustment
The air damper is set in factory. This regulation is purely indicative. Each installation
however, has its own working conditions: actual nozzle output; positive or negative
pressure in the combustion chamber, the need of excess air, etc. All these conditions
may require a different air damper setting.
Air Damper (A) – 15/21 Burner Only
Air Damper (B)
Air Damper (A) – The main air damper can be set in
either of two positions. To set the positions of the damper,
proceed as follows: Remove the secondary air damper (B)
loosening the screws (1). Loosen the screw (2) and rotate
the main air damper (A) to the required position. Retighten
the screw (2) and put back the secondary air damper (B).
Air Damper (B) – The purpose of
this damper is to perform a finetuning of the inlet air. Tuning of this
device is possible by turning the
screw (3).

Commissioning & Servicing
9.1
Commissioning
Note:It is the responsibility of the installer to ensure that the boiler is properly
commissioned by an OFTEC trained and registered technician. Failure to do
so WILL invalidate ALL warranties.
Before firing ensure that all the baffles are in place, as they may have been displaced
during transit; Refer to the General Information section. Switch the boiler on,
ensuring all controls are calling for heat.
The oil pump pressure must be checked by fitting a pressure gauge to the pump
pressure port. If necessary the pressure should be adjusted until it corresponds with
the value in the Technical Data section for the required output. Using a smoke pump,
check the smoke number. It should be zero.
Using a flue gas analyser, check the CO2 content and flue gas temperature once
the boiler is hot. Testing while the boiler is still relatively cold gives inaccurate results
and leads to incorrect adjustments being made.
Where a balanced flue has been fitted ensure the air duct connecting the flue and
burner has been properly connected before commissioning.
To comply with the building regulations OFTEC form CD11 should be completed
and a copy left with the householder.
9.2
Servicing
9.2.1 General Requirements
It is recommended that the appliance is serviced annually by a Warmflow or an
OFTEC registered service technician in accordance with the recommendations
laid out in OFTEC’s technical information book 2 – ‘Pressure Jet Appliances
– Commissioning Requirements for Technicians’.
Additionally, when servicing, special attention should be paid to the condition of the
oil nozzle, flexible oil line, fuel filter, door insulation, sealing rope and secondary heat
exchanger door seal. If found to be defective they must be replaced.
The system corrosion inhibitor level must be checked (instant on-site test kits are
available from inhibitor manufacturers) and additional inhibitor must be added if the
system is found to be under-dosed. Refer to the inhibitor manufacturer for further
guidance.
Note:All product warranties will be invalidated if the appliance is not serviced
annually by a Warmflow or OFTEC trained and registered technician.
