AIRWASH & PRIMARY AIR CONTROLS

CONTROLS, GENERAL

1.14 Use a gloved hand to operate air controls.

1.18 The controls fitted to the system will provide two functions:

Airwash Control
Open

HEATING SYSTEM controls

—To control the comfort level in the house.
—To maintain safety in the event of misuse or mechanical
failure.

COMFORT CONTROLS
1.19 A programmable timer switches the pump on when heat is
required and off when it is not.

Airwash Control

The timer, when combined with a room thermostat and / or
thermostatic radiator valves, enhances the comfort levels in
the house.

Some room thermostats combine the function with
the timer and can be programmed to reduce the room
temperature rather than turning the system off. This is
effective in not allowing rooms to become too cold and
speeding up recovery time.

1.20 The hot water cylinder can also be fitted with a thermostatic
valve which turns off the flow when the cylinder has
reached the desired temperature, but the heat leak radiator
will have to be bigger to cope with the extra load when the
tank is isolated.

DOOR HANDLE
1.15 Use a protected gloved hand to operate.

SAFETY CONTROLS
DO NOT OPEN THE DOOR WITH BARE HANDS

1.21 A high limit thermostat is fitted to the gravity flow pipe set
at 80˚C. This thermostat should be connected to the pump
so that the pump is turned on if the temperature exceeds
80˚C. This will prevent accidental boiling in the gravity
circuit.

To Open and Close
Drop door tool over knob to fit.
Rotate 1/ 2 turn anti-clockwise to open.
Rotate 1/ 2 turn clockwise to close.
Lift up door tool to remove

1.22 It is also recommended to fit a low limit thermostat on the

1.16 Never open the door with your bare hands.
1.17 Closing the door is the reverse of the previous.

NOTE – Further information on solid fuel central heating
systems can be found in the HETAS engineers training
manual.

USER INSTRUCTIONS
WARNING

Properly installed, operated and maintained this
appliance will not emit fumes into the room.

Precautions must be taken to ensure that this build up of
condensate does not overflow from the appliance onto any
surrounding fabric of the room e.g. carpets.

NOTE - THIS CONDENSATION IS NORMAL DURING
FILLING AND DOES NOT INDICATE A FAULTY OR
LEAKING STOVE.

Occasional fumes from de-ashing and refuelling may occur.

Persistent fume emission is potentially dangerous and
must not be tolerated.
If fume emission does persist:

—Open doors and windows to ventilate the room.

—Allow fire to burn out or safely dispose of fuel from the
appliance.

2.6

NORMAL RUNNING
2.7

During normal running this condensation should be minimal
if the system is fitted with the low limit thermostat as
detailed in 1.22 (above). This low limit thermostat prevents
the system pump from running until the stove has reached
temperature.

SEASONAL USE

2.8

If this appliance is unused for lengthy periods of time it
should be periodically checked to ensure that condensation
is not building up within the stove.

—Check for chimney blockage and clean if required.

CONDENSATION
CAUTION WHEN FILLING
2.4

2.5

Wood Length

When filling the boiler with water for the first time, the cold
water entering the water jacket can cause condensation to
form on the surfaces of the appliance (inside and outside).
In certain conditions this condensation could result in a
considerable amount of water, in some cases enough to fill
the bottom of the appliance. This could be even worse if
the house has recently been re-decorated, wet plastered or
any other work has been undertaken which could result in
high humidity.

USER INSTRUCTIONS
THERMOSTAT OPERATION

5.17 This appliance can be fitted with a thermostat kit to control
the temperature of the boiler. See the instructions included
in the kit for operation details.

6. Burning tips
6.1

Symptoms of poor performance related to flue draught
include:
—Excessive fuel consumption (high flue draught).
—Poor burning control and/or overheating (high flue
draught).
—Wind noise from air controls (high flue draught).
—Difficulty getting a fire going and keeping it burning well
(low flue draught).
—Low heat output (low flue draught).
—Smoke entering room when doors are opened (low flue
draught).

Fuel Quality (Wood)
Use wood with a moisture content of less than 20%.
Seasoned logs have the bark beginning to lift and peel away
and cracks radiating from the centre. They feel lighter than
fresh cut wood of a similar size and sound hollow when
struck against each other. Logs should not feel damp or have
moss or fungal growths.

The construction, position, size and height of the chimney
all affect the performance of the flue draught.
Other factors effecting the flue draught include:
—Nearby trees or buildings causing turbulence.
—Outside temperature.
—Outside weather conditions.
—Incorrect additional ventilation to building.
—Blocked flue or chimney.

Symptoms related to wet wood:

—Difficulty starting and keeping a fire burning well.
—Smoke and small flames.
—Dirty glass.
—Rapid creosote build-up in the chimney.
—Low heat output.
—Short burn times, excessive fuel consumption and blue/

6.3

Air inlets puffing smoke
Combustion gases can build up in the firebox and ignite
as small explosions, causing smoke to puff out of the air
inlets and other openings. This occurs if the air controls
are shut soon after adding new fuel to a very hot fire. Stop
by opening the air controls to increase combustion air and
burning rate.

6.4

Flue Draught
The chimney has two main functions:

To safely remove the smoke, gases and fumes from the
house.
To provide a sufficient amount of draught (suction) in the
appliance ensuring the fire keeps burning.

Draught is caused by the rising hot air in the chimney when
the appliance is lit.

To reduce these problems:

—Use good quality kindling wood to start the fire.
—Burn initially at a high temperature for a short period.
—Fit a rain cowl to the chimney.
Your installer should advise you on possible solutions.

—Close the air controls and allow the appliance to go out.
—Ventilate the room to clear the fumes.

If the appliance emits smoke into the room continuously:

Do not re-light the appliance until the problem is solved.

USER INSTRUCTIONS
17.2 Riddling mechanism jamming

This occurs when fine ash builds up under the riddling bars
preventing movement. To prevent this:
—Follow a regular cleaning routine for the inside of your

appliance.
—Lift out the riddling mechanism and remove all ash.

—Replace riddling mechanism when cleaning is complete.

16. Seasonal use
16.1 Clean and service the appliance if it is not used during the
warmer periods of the year as detailed in the Maintenance
and Servicing section.
16.2 Set the air controls 50% open to keep the appliance
ventilated and stop the build-up of any moisture inside.

17.3 Glass cracking

Do not over tighten the screws on the glass clips when
replacing the glass. This causes stress and the intense
temperature changes can cause the glass to crack. For
replacement glass contact your local Yeoman retailer.

16.3 Before re-lighting the appliance:

—Remove the baffle.

—Clear any debris that may have accumulated.

—Check the flue is clear of any blockages.

17.4 Appliance is producing tar

This can be identified by:

16.4 If this appliance is unused for lengthy periods of time it
should be periodically checked to ensure that condensation
is not building up within the stove.

NOTE – THIS CONDENSATION IS NORMAL AND DOES
NOT INDICATE A FAULTY OR LEAKING STOVE.

16.5 If the stove is going to be unused for very long periods of
time it is recommended to drain the system.

17. Troubleshooting tips
17.1 Stove glass blackening

This has four possible causes:
1.

—A very strong pungent smell shortly after the appliance is

—Glass blackening.
—Thick, brown, sticky tar oozing from the pipe joints.

lit and heats up.

This is caused by burning damp wood and running the
appliance at too low a temperature.

Use well seasoned wood and operate the appliance within
the ideal temperature range.

Tar is a major cause of chimney fires. If the appliance
experiences problems with tar build up consult a chimney
sweep before continued use of the appliance.

17.5 All or some of the radiators do not get hot

Incorrect use of Airwash
See User Instructions, Sections 1, 4 and 5 for the correct
use of the air controls.

Open up the airwash to make
a hotter fire

Burning unseasoned wood
See User Instructions, Section 3 to identify when wood is
ready for burning.

Burning wood

Wood is burning too
slowly

If fitted set the thermostat to a
higher setting
Burn dryer wood
Burn better quality wood
Reduce ashbed to 1" thick

Stove operated at too low a temperature
A stove pipe thermometer can identify this problem (Stovax
part no. 3046). The ideal working temperature range is
130°C - 250°C (270°F - 480°F). Failing to close down the
Primary Air Control once the appliance has heated up to
this range may cause the appliance to exceed the ideal
temperature range and to over-fire. Over-firing can cause
permanent damage to the appliance and invalidates your
warranty. Burn with the Airwash Control fully open for
approximately 20 minutes to cure this.

Burning Solid
Mineral fuels

Fuel is burning too
slowly

Open up the primary air to
make a hotter fire. If fitted,
set the thermostat to a higher
setting
The fire needs riddling to
remove ash. De-ash the fire
Empty the ash pan.

All Fuels

The problem may be caused by damping down the
appliance during periods of extended burning.

Stove is not producing
much heat.

System faults

Problems with the flue, in particular insufficient air pull.
If the flue is not working efficiently the glass can blacken.
A flue which has too much downdraft may be too short,
needs lining, or has too many bends. This can also cause
blackening of the stove glass. Contact the installer or a flue
specialist for advice.

Not enough fuel.
Bleed the radiators to ensure
there are no air locks.
Incorrect system design seek
professional assistance
Too many radiators in the
system exceeding the stoves
capabilities.

INSTALLATION INSTRUCTIONS
3. Hot Water Cylinder

CENTRAL HEATING SYSTEM
1. General

3.1

The domestic hot water cylinder must be an indirect vented
double feed type to meet national standards** and should
have a minimum capacity of 117 litres. Houses with more
than one bathroom or a separate shower will need a bigger
tank.

This appliance gives out heat in two ways:

—Directly into the room in which it is fitted through
convection and radiation.

Fully insulate the tank.

—Hot water to heat radiators and domestic hot water.

The water draw off pipes to the taps should be in a dead
leg connection from the vent pipe.

The installation must comply with building regulations and
use best practice advice.

4. Open Vent And Cold Feed System

2. Boiler Sizing
2.1

4.1

This system must be fitted with a minimum of 22mm
diameter open vent discharging into a heat resisting feed
and expansion tank. There must be at least 25mm air gap
between the end of the pipe and the water level. The
cistern tank should have an overflow with a minimum
diameter of 22mm

It is very important to determine the correct size of
appliance for the house:

—Too big a boiler will run too hot and will not be efficient.

—Too small a boiler will not maintain the desired

The cold feed must be a minimum 22mm and enter the
system as the last connection on the common boiler return.

2.2

Size the boiler correctly by calculating the following heat
loads:

The open vent and cold feed must not be fitted with any
valves, manual or automatic.

RADIATORS - the amount of heat required to run the
radiators efficiently. The correct size of radiator depends
on the required temperature for the room, the room heat
losses and the radiator manufacturer’s guides.

Do not use plastic pipe in any part of the flow and
return.

2.3

2.4

temperature.

5. Heat Leak Radiator

HOT WATER - the amount of heat required to provide the
desired amount of domestic hot water.

5.1

A heat leak radiator must be fitted in the gravity circuit to
dissipate any excess heat produced from the boiler when
connected demand is low. The domestic hot water cylinder
may not be able to disperse heat at all times due to modern
insulation. This radiator is commonly fitted in the bathroom
and should be rated at 2kW (6500 btu) or 10% of the total
boiler output.

This radiator ensures that the appliance is not shut down
completely for long periods resulting in the fire going out.

Fit the heat leak radiator in the gravity circuit using 22mm
pipe reducing to 15mm for no more than 300mm before
the radiator.

Fit the radiator with two ‘lock-shield’ valves that are set
in the fully open position and cannot be shut down. Use
diagonal connections. Do not fit thermostatic valves or
manually adjustable valves to the heat leak radiator.

In the UK:
* See BS 5449:1
** See BS1566 Part 1 grade 3 minimum

LOSSES – the amount of heat lost in pipe work - typically
10% of the combined radiators and hot water loads.
There are national guidelines for calculating these figures*.
Careful consideration must be given to where the appliance
is fitted. It must be sized correctly for the heat load required
and the size of the room. These requirements can be found
in the Technical Specifications.
All Yeoman appliances are thermostatically controlled. The
burning rate is adjusted to the demands of the connected
heat load. If the radiators do not require heat then the
thermostat will act to shut down the appliance and the
direct heat output to the room where it is fitted will reduce
(see heat output graph on page 15 to show the ratio
between direct heat output and water heat output). To
prevent the room becoming too cold, fit a thermostatically
controlled radiator as well as the appliance.

INSTALLATION INSTRUCTIONS
9.1

6. Pump
6.1

Where a pump is fitted into the circuit it should be
adjustable so that the flow can match the system
requirements. Fit isolation valves to enable removal for
servicing. The pump must have at least 1.5 meters of static
head.

To overcome this problem it is common practice to fit
an injector tee where the pumped central heating return
re-joins the gravity return from the hot water cylinder. This
injector tee induces a much stronger gravity flow when the
pump runs.

7. Electrical Supply
7.1

Electrical connections must meet the requirements of
national Building Regulations* and standards**, along with
any European, local regulations and working practices that
may apply. Should conflict occur between these instructions
and these regulations then the regulations must be followed.

Only use proprietary injector tees, homemade ones are
difficult to get right.

9.2

When installing a system that has pumped central heating
and gravity hot water it is recommended to use all 4
boiler tappings. Each flow and return should be diagonally
opposite each other.

The connection to the mains supply should allow
complete electrical isolation and only serve the heating
circuit pump.

10. Fully Pumped System

All water connections should be completed by a competent
person to meet the requirements of local water authority
by-laws.

10.1 In many installations (especially new build) a fully pumped
system is the best choice to give increased control.

CONVENTIONAL Pipe work systems

All pipe work must be able to operate at above 100
degrees Celsius. Any pipe work installed in an exposed
position e.g. loft space must have provision to prevent
freezing.

11.1 Do not fit this appliance to sealed or pressurised systems or
an unvented hot water cylinder.

8. Gravity Pipe Circuit
To prevent the risk of boiling it is essential to arrange the
pipe work and position the hot water cylinder and heat
leak radiator so that gravity circulation can take place when
the pump is not running. Position the cylinder and the
radiator vertically above the boiler with sufficient height to
encourage gravity flow.

8.2

Horizontal pipe work in a gravity system must have an
incline of at least 5mm in every 1000mm and a minimum
diameter of 28mm. Vertical pipe must have a minimum
diameter of 22mm.

8.3

Any motorised valves fitted in this circuit must return to the
fully open position when the power is interrupted.

WARNING - To prevent the risk of boiling it is essential
to arrange the pipe work and position the hot water
cylinder and heat leak radiator so that gravity circulation
can take place when the pump is not running. Any
motorised valves fitted in this circuit must return to the
fully open position when the power is interrupted.

11. Sealed (Pressurised) System

Ensure the pipe work system has sufficient drain
points to enable the complete removal of water for the
purposes of servicing.

8.1

The most common arrangement is to have a pumped
central heating circuit combined with a gravity hot water
circuit. This arrangement requires careful balancing of the
two in order to avoid the gravity circuit being starved when
the pump is running.

INSTALLATION INSTRUCTIONS
Heating system controls
CONTROLS GENERAL
1.1

The controls fitted to the system will provide two functions:

— To control the comfort level in the house.
— To maintain safety in the event of misuse or mechanical
failure.

1.8

Precautions must be taken to ensure that this build up of
condensate does not overflow from the appliance onto any
surrounding fabric of the room e.g. carpets.

NOTE - THIS CONDENSATION IS NORMAL DURING
FILLING AND DOES NOT INDICATE A FAULTY OR
LEAKING STOVE.
NORMAL RUNNING
1.9

SEASONAL USE

COMFORT CONTROLS
1.2

1.3

This primarily consists of a time clock wired into the pump.
The pump is switched on when heat is required and when
it is not, the pump is switched off.
The time clock, when combined with a room thermostat
and or thermostatic radiator valves, enhances the comfort
levels in the house.
Some room thermostats combine the function with the
time clock and can be programmed to reduce the room
temperature rather than turning the system off. This is
effective in not allowing the rooms to become too cold and
speeding up recovery time.

1.5

NOTE – THIS CONDENSATION IS NORMAL AND DOES
NOT INDICATE A FAULTY OR LEAKING STOVE.

If the stove is going to be unused for very long periods of
time it is recommended to drain the system.

NOTE – Further information on solid fuel central heating
systems can be found in the HETAS engineers training
manual.

The hot water cylinder can also be fitted with a thermostatic
valve which turns off the flow when the cylinder has
reached the desired temperature but the heat leak radiator
will have to be bigger to cope with the extra load when the
tank is isolated.

SAFETY CONTROLS
1.4

1.10 If this appliance is unused for lengthy periods of time it
should be periodically checked to ensure that condensation
is not building up within the stove.

This primarily consists of a high limit thermostat fitted to
the gravity flow pipe set at 80˚C, this thermostat should be
connected to the pump so that the pump is turned on if
the temperature exceeds 80˚C. This will prevent accidental
boiling in the gravity circuit.

LINK UP SYSTEMS

For information on how to link solid fuel boilers to other
heating appliances see Information For Dual System Link
Up Methods (PM286). This can be obtained through Stovax.

Call (01392) 474011, email info@stovax.com or visit
www.stovax.com for details.

Always seek the advice of a competent person* before
linking another heating system to a solid fuel boiler.

In the U.K:
* Registered body: HETAS (GB only)/INFO (Republic of
Ireland)

It is also recommended to fit a low limit thermostat on the
central heating return set at 45˚C, this thermostat will turn
the pump off if the return temperature falls below 45˚C.
This will prevent corrosion and condensation within the
stove.

CONDENSATION
1.6

When filling the boiler with water for the first time, the cold
water entering the water jacket can cause condensation to
form on the surfaces of the appliance (inside and outside).

1.7

In certain conditions this condensation could result in a
considerable amount of water, in some cases enough to fill
the bottom of the appliance. This could be even worse if
the house has recently been re-decorated, wet plastered or
any other work has been undertaken which could result in
high humidity.

COMMISSIONING
COMMISSIONING
1.1

1.2

To commission:
— Replace the log retainer.
— Check the door alignment and catch operation, adjust if
required, see Installation Instructions, Section 6,
Adjusting Door Hinges.
— Check the soundness of door seals, castings and joints.
— Check the operation of the air controls.
— Ensure the system has been filled with water and
includes a suitable inhibitor.
Now carry out a final smoke draw test:
— First warming the flue with a blowlamp, or similar, for
about 10 minutes.
— Place a smoke pellet on the centre of the grate, with the
air controls open.
— Close the door. Smoke should now be drawn up the flue
and be seen to exit from the flue terminal.
— Complete test with all doors and windows closed in the
room where the appliance is fitted.
— If there are any extractor fans in adjacent rooms, the test
must be repeated with the fans running on maximum
and interconnecting doors open.
— Check the effect of ceiling fans during the test.
If the test fails, re-check the suitability of the flue system
and ventilation. An inadequate air supply to the room is
potentially dangerous.
— Light the appliance and slowly increase the temperature
to operating levels.
— Ensure no combustion products enter the room.
— Open the main fire door when the appliance reaches
operating condition and carry out a spillage test with a
smoke match or pellet around the door opening.
— Run the system up to temperature.

It is essential to balance the central heating system in order
to achieve an even heating performance across all of the
radiators in the house. Balanced means each radiator having
a 10˚C difference in temperature between the flow and the
return, ideally 80˚C flow and 70˚C return.
Have the system running and adjust the appliance
thermostat so that the flow temperature measured near
the appliance is approximately 80˚C. Ensure that all valves
including lock-shield valves are in the fully open position
and the pump is at its estimated correct speed. If there are
thermostatic radiator valves, have these on maximum setting
and ensure that they do not activate.
Ensure that the radiators have been bled of air.

Write down the return temperature of each radiator in turn
and its difference to the flow temperature at the appliance.
Make sure that the flow temperature remains constant.

The radiator with the greatest difference (the index radiator)
and any other radiator within 1 degree should be left with
the lock-shield fully open. The remainder of the lock-shield
valves should be closed to about 1/3 open. Leave the
system to stabilise, this could take some time.

When the system has stabilised, write down the new
difference between the flow and return temperatures and
any which differ from the index radiator by more than 1
degree will need further adjustment, some valves will have
been closed too much and others not enough, usually the
adjustments need to be only a fraction of a turn at a time.
Leave sufficient time for the system to stabilise after each
adjustment.

When the radiator temperatures are starting to become
consistent, but before final adjustments, the index radiator
needs to be considered, if the return temperature of this
radiator is not near 70 degrees then the pump will need
to be adjusted to either provide more (to increase the
temperature) or less flow to decrease the temperature.
Again, sufficient time will need to be left to allow the system
to stabilise after adjusting the pump speed.

When the radiator flow and return temperatures are correct
the final adjustments can be made and the lock-shield
covers replaced.

Knowing how far to shut down a valve to get the desired
change in flow and return temperature, and knowing how
long to wait for the system to stabilise, takes a little time and
practice.

1.3

If excessive spillage occurs:

1.4

Finally:

— Explain the safe operation of the appliance and the
use of the controls to the user and the importance of
only using suitable fuels.

— Allow the appliance to cool and re-check the flue system
and ventilation.

All open flued appliances can be affected
by temporary atmospheric conditions which
may allow fumes to enter the house. Because
of this it is recommended that an electronic carbon
monoxide detector conforming to BSEN50291
be fitted and maintained.

BALANCING THE SYSTEM

— Explain the cleaning and routine maintenance
requirements.

— Explain the requirement to use a suitable fireguard
when children, elderly or infirm persons are near the
appliance.

—Record dealer/supplier and installer details in
Appliance Commissioning Checklist (page 3,
Instructions for Use).

—Record serial number in Appliance Commissioning
Checklist (page 3, Instructions for Use). This number
is required when ordering spare parts and
making warranty claims.

— Give the copy of the Instructions to the customer.
