Burner Lockout
The burner is equipped with a flame failure device. When activated the reset button on the burner control box is
illuminated. Refer to the fault finding section of the handbook to identify possible causes.
The test switch is provided for the service engineer, in normal operation the switch should be left in the “PROG”
position for Wallstar and System Wallstar boilers and in the “NORMAL” position for the Wallstar Combi.
Switching The Boiler On
- Turn on the oil supply
- Switch on the mains supply
- Set the timer control to “on”
- Set the boiler control thermostat to the required setting
Switching The Boiler Off For Long Periods
- Have the boiler serviced
- Switch off the mains supply
- Turn off the oil at the tank
Pump Priming
If the burner fails to lift oil, the pump may be dry and require priming. To prime the burner, fill a suitable container,
such as a jar, with heating oil, disconnect the flexible oil line at the isolating valve and place the end into the container.
Hold the container above the height of the burner and press the lockout reset button, once the pump has pulled the oil
from the container through, it is primed and can be reconnected to the main supply.
Oil Delivery
Switch the boiler off during an oil delivery, wait for a short period before switching the boiler back on to allow sediment
in the bottom of the oil supply tank to settle.
Maintenance
Your boiler should be serviced annually. Failure to have this done will invalidate your warranty and may also lead to
inconvenient breakdowns. A “Benchmark” service log can be found at the back of this manual.
If you have difficulty in locating a service engineer, please contact our service department who may be able to provide
you with the name of an engineer in your area.

Please contact our sales department for further information on burner spares.
Burner Lockout
The burner is equipped with a flame failure device. When activated the reset button on the burner control box is
illuminated. Refer to the fault finding section of the handbook to identify possible causes.
The test switch is provided for the service engineer, in normal operation the switch should be left in the “PROG”
position for Wallstar and System Wallstar boilers and in the “NORMAL” position for the Wallstar Combi.
Switching The Boiler On
- Turn on the oil supply
- Switch on the mains supply
- Set the timer control to “on”
- Set the boiler control thermostat to the required setting
Switching The Boiler Off For Long Periods
- Have the boiler serviced
- Switch off the mains supply
- Turn off the oil at the tank
Pump Priming
If the burner fails to lift oil, the pump may be dry and require priming. To prime the burner, fill a suitable container,
such as a jar, with heating oil, disconnect the flexible oil line at the isolating valve and place the end into the container.
Hold the container above the height of the burner and press the lockout reset button, once the pump has pulled the oil
from the container through, it is primed and can be reconnected to the main supply.
Oil Delivery
Switch the boiler off during an oil delivery, wait for a short period before switching the boiler back on to allow sediment
in the bottom of the oil supply tank to settle.
Maintenance
Your boiler should be serviced annually. Failure to have this done will invalidate your warranty and may also lead to
inconvenient breakdowns. A “Benchmark” service log can be found at the back of this manual.
If you have difficulty in locating a service engineer, please contact our service department who may be able to provide
you with the name of an engineer in your area.

Boiler Installation
Regulations
The Installation of oil fired boilers must comply with the following Standards and Codes of Practice:
BS 5410-1:1997 Oil installations up to 45kW
BS 5449 Forced circulation hot water central heating systems for domestic premises
BS 7593:2006 Treatment of water in hot water central heating systems
Building Regulations Part L1 Part J 2006 England and Wales, Part F Scottish Regulations and Technical
Booklet L Northern Ireland
BS 7671:2008 Electrical Regulations
BS 7074 Code of practice for sealed systems
Boiler Sizing
It is important to establish the correct size of boiler required. Boiler output will depend on a number of factors,
including:
- The preferred room temperatures
- Location winter temperature
- Structural and ventilation heat losses
- Domestic hot water requirements
This is a complicated calculation. We recommend you employ the services of a heating engineer, who will determine
the correct size of boiler required for your property.
Refurbishing an Old System
IMPORTANT – Before installing a new boiler:
The system should be chemically cleaned to remove debris, in the form of black magnetite sludge and lime scale that
accumulates in radiators and pipe work. Failure to do this will result in debris adhering to the clean surfaces of a new
boiler, causing kettling or knocking noises. It also prohibits efficient heat transfer. A cleanser such as Fernox
Superfloc should be added to the system 48 hours prior to changing the boiler.
System Protection
After Installation
Flush the system with a cleanser such as Fernox Superfloc to remove traces of flux residues, grease, metal swarf,
solder pieces and oils used during component manufacture.
After Flushing
Add a corrosion inhibitor such as Fernox MB-1. This will minimise the chemical action and chemical change that takes
place in a systems primary water and system components.
Note: The manufacturer’s usage instructions for chemical cleaners and inhibitors should always be followed.
Please refer to BS 7593:2006 for a detailed explanation of cleansing procedures.
Protection of DHW Heat Exchanger (Wallstar Combi)
We recommend that a water scale reducer is installed in areas of hard water.
Boiler Installation - Continued
Boiler Location
IMPORTANT - Boilers should be installed on the ground floor only.
Noise levels – consideration should be given to the following:
- Small rooms will accentuate noise levels.
- Where a flue terminates near the boundary of an adjoining property, consideration should be given to
possible noise disturbance as some people are sensitive to even low noise levels.
Bathroom and bedroom installation should only be considered where there is no alternative.
Wall Construction
The boiler must be installed in a suitable load bearing external wall – a lintel is not normally required.
For walls constructed of timber, stramit or similar material, the structural material must support the weight
of the boiler when filled with water. A stud work frame should be constructed when appropriate.
It is not necessary to construct a heat barrier around the wall duct.
Where the external cladding is of weatherboard or similar, construct a “picture frame” for the wall duct trim
to seat against.
Wall Thickness
The Wallstar condensing models are supplied with telescopic wall ducts and flues, designed to fit through
exterior walls 210mm to 340mm thick. However with the addition of a 100mm extension kit, it is possible
to install a Wallstar condensing boiler in walls up to 440mm thick.
IMPORTANT - Be sure to measure your wall thickness before purchase.
Wall Duct & Flue Extension Kits
Note: Only one extension kit per boiler is permitted.
The extension kit is fitted to the inner half of the telescopic wall duct.
Extension Kit Size Part Number
Wallstar 12/14CA Wall Duct & Flue

Flush the system with a cleanser such as Fernox or similar to remove traces of ux residues, grease, metal swarf,
solder pieces and oils used during component manufacture.
Add a corrosion inhibitor such as Fernox or similar. This will minimise the chemical action and chemical change that
takes place in a systems primary water and system components.
Boilers should be installed no higher than 2.5 m- See diagram on page 17.

Flue Terminating Positions
Information taken from BS 5410-1:1997 and The Building Regulations: Approved Document J
Notes:
1 - Terminals should be positioned so as to avoid products of combustion accumulating in stagnant pockets around
the building or entering into buildings.
2 - Where a flue is terminated less than 600mm away from a projection above it and the projection consists of plastics
or has a combustible or painted surface, then a shield of at least 750mm should be fitted to protect these surfaces.
3 - If the lowest part of the terminal is less than 2m above the ground, balcony, flat roof or other place to which any
person has access, the terminal should be protected by a guard.
4 - Where a flue terminates near the boundry of an adjoining property, consideration should be given to possible noise
disturbance as some people are sensitive to even low noise levels.
5 - Boilers can produce sulphur deposits, occasionally these deposits are discharged out of the flue, this should be
taken into consideration when planning to site flues over patios etc.

Fuel Supply System
Oil Tank
We recommend the use of plastic oil tanks, they require less maintenance than steel tanks and are longer lasting.
A bunded oil tank may be required on any environmentally sensitive site where spillage of oil could pollute rivers,
ponds, or any other water courses. Please refer to the appropriate requirements when locating oil tanks: “Control of
Pollution Regulations”, “Building Regulations” and OFTEC Technical Paper T19.
Oil Supply
Fuel Tank Below the Burner
The fuel pump can lift fuel to a height of 2.5m. A two pipe system or deaerator (Tiger Loop, 3K or similar) is not
required. For heights above 2.5m, please consult our technical department.
Pipework
Soldered fittings should not be used, as the joints will fail in the event of a fire. Flux deposits may damage the pump
and fuel may deteriorate the solder within the joint. Galvanised pipes and fittings must not be used. The aggressive
action of the fuel will erode the zinc and damage the fuel pump.
Keep the number of pipe joints to a minimum, form bends rather than using compression fittings.
Jointing Compounds
Jointing compounds should be used with care. Excessive amounts can cause blockages, and fragments may cause
failure of the fuel pump or the non-return valve. We recommend the use of a non-setting liquid pipe sealant.
Automatic Isolation of the Fuel Supply in the Event of a Fire
In accordance with Document J of the Building Regulations, we provide “a means of automatic isolation of
the fuel supply” in the form of a remote acting fire valve which must be fitted inline of the fuel supply in
accordance with BS 5410-1:1997. A clip is provided in the top of the wall duct for the fire valve capillary
bulb.
Oil Filtration
All boilers are supplied with flexible fuel lines with in line filter included. If the flexible fuel line needs replacing it must
be replaced by an item of this type (Part Number: BS099). A paper element filter is also supplied and must be fitted
adjacent to the boiler, replacement filters are available (Part Number: BS076). Where a steel oil tank is installed we
recommend a further paper element filter is also fitted adjacent to the oil tank.
In accordance with Document J of the Building Regulations, “a means of automatic isolation of
the fuel supply” in the form of a remote acting re valve must be tted inline of the fuel supply in
accordance with BS 5410-1:1997. A clip is provided in the top of the wall duct for the re valve capillary
bulb.
All boilers are supplied with exible fuel line. If the exible fuel line needs replacing it must be replaced by an item of this
type (Part Number: BS012). A paper element lter is also supplied and must be tted adjacent to the boiler, replacement
lters are available (Part Number: BS076). Where a steel oil tank is installed we recommend a further paper element
lter is also tted adjacent to the oil tank.

Fit the burner to the mounting flange on the silencer box.
17. Connect The Fuel Line
Connect the fuel line from the burner, to the oil supply.
IMPORTANT: The Wallstar comes supplied with a remote
acting fire valve and has a non-return valve attached to the
burner bump. No additional non return valve must be used.
Should the boiler be used in conjunction with a purpose designed
underground tank, the foot valve found inside such tanks must be
removed or at least rendered ineffective. In addition to the sealed
fuel filter found in the boilers flexible fuel line, a replaceable
element fuel filter must be fitted near the tank.
Note: Please refer to page 17 of this manual for oil tank

19. Priming The Burner
Ensure both power and fuel supplies to the boiler are switched
on. Press the reset button, the burner will start its firing
sequence. To release air from the oil line, slacken the vent plug
during this sequence. If ignition fails the burner will go to lock
out, wait 60 seconds and repeat the procedure.
20. Test The Fuel Supply
With the burner running, check the fuel supply for air leaks. It is
normal for a static air bubble to remain at the highest point of the oil
line, but a continuous stream of bubbles through the oil line
indicates that air is being drawn in. This must be cured before
proceeding.
21. Access Door
Fit the access door onto the wall duct, secure it in place by
tightening the 2 screws located on both sides.
22. Flue Positioning
Pull the end of the flue out until the flange on it sits flush
against the back of the access door.
.
22. Commissioning the Boiler
Installation is complete. The boiler must now be commissioned
by a competent engineer. The “Benchmark” log found at the
back of this manual should be completed and the warranty
documentation returned to HRM Boilers Ltd.

The Condensate Drain
Condensate Drain Installation
The Wallstar condensing range of boilers use a single unit heat exchanger similar to those in the conventional noncondensing Wallstar. However, in order to drain away condensate produced in operation, there is a stainless steel
tube connection on the underside of the flue, which comes pre-connected to a flexible hose. The flexible hose
supplied forms the condensate trap and is terminated with a rubber fitting which will seal inside 22mm plastic waste
pipe.
The hose can either exit the boiler casework through the bottom of the wall-plate or be taken out through the bottom
of the wall duct, in both cases it must be connected into a soak-away (fig 1.1), the household drains (fig 1.2), or a
vertical stack (fig 1.3), via the supplied condensate trap.

No heating or domestic hot water (DHW)
- If the heating and DHW works when the test switch is in the “test” position, check the plug and socket
connection from the micro switch.
- Is the circulation pump working?
Cold DHW, heating functions satisfactorily
- Pipe work for the “mains in” and DHW have been connected the wrong way round.
Warm DHW, heating functions satisfactorily
- Is the system pressure set to one bar (when cold)?
- Is the black plastic plug in the automatic air vent open?
- Is there a combustion problem/faulty nozzle?
- Is the mains water temperature low? The boiler will raise the mains water temperature by 35
°C at a
flow rate of 10.5 litres per minute.
- Check the operation of the mixing valve – is the “hot water” (right hand) inlet to the valve excessively
hot indicating that water is not flowing through the valve?
- If the “hot water” inlet to the mixing valve is cool, the plate heat exchanger may be
blocked/contaminated.
No heating, DHW functions satisfactorily
- Has the plunger on diverter valve stuck in the out position? Press the plunger a few times to free, or
dismantle the diverter valve assembly and clean.
DHW flow is less than 10.5 litres
- Is the mains water pressure sufficient? It should be greater than 1.5bar or 15 litres per minute.
- Is the mains water filter blocked?
Heating runs constantly
- Has the switch under the burner been left in the test position?
- Has the heating time clock been left in the permanently “on” position?
The boiler overheat thermostat needs resetting frequently
- Has the boiler lost system pressure?
System pressure is low
- Recharge system pressure by opening the filling loop valve and increasing pressure to the jet point
indicator on the pressure gauge (approximately 1 bar).
