5kW Wide Woodburning Stove

2 of 10
Recommended fuels
Ironwood stoves are designed for burning wood only. Choosing the correct log length is important and this depends
on the type and size of the stove. For the Ironwood 5kW wide we recommend a 14”log which will ensure you get a long
clean burn by having the size to comfortably fit the firebox and grate. Most importantly is ensuring the wood you choose
is dry with a moisture content of no more than 20%. If the fuel is damp with a high moisture content this will result in
poor combustion and also result in layers of soot and tar within the firebox chamber and chimney. This could potentially
cause a chimney fire if allowed to build up over time. The glass will also mist up and the crystal clear view of the fire will be
disrupted.
Do not
• Do not burn unsuitable fuels such as treated waste wood (eg old furniture, pallets or fence panels)
or household rubbish. Treated waste wood and household rubbish can emit harmful fumes and toxic
pollutants into your home when burnt.
• Do not use liquid fuels as a fuel or an incinerator.
Burn only seasoned or kiln dried firewood with a moisture content
of less than 20%. We recommend using ‘Ready to Burn’ fuel from
an accredited Woodsure fuel supplier.
Lighting the first fire
The first few fires should be kept at a low temperature with
a few sticks of kindling in order for any cement and seals to
harden. On the third fire the temperature can be increased
and logs introduced. At this stage the temperature will
increase allowing the stove paint to cure and harden.
It is normal that the curing paint will smell and even create
a misty haze in the room and a window or door to outdoors
should be opened. The smell should stop after the first
few firings. Take care not to touch the stove paintwork as
during the curing process the paint is soft and can mark
easily.

STEP 1
Lighting- fully open, 2nd ‘click’
Pull the air wash lever open towards you which will fully
open all necessary vents to start the fire. Place firelighters/
newspaper and dry kindling wood on the grate. Light the
paper or firelighters and leave the door ajar to allow the
fire to establish. Add a few small diameter logs and after
the fire is established larger logs can be introduced, usually
after 10-15 minutes. The stove door should be closed fully
at this point. Move to step 2.
Do not run the fire with the door ajar except for initial
lighting and refuelling as this can cause over firing and
damage the appliance.
STEP 2
Moving towards optimum temperature
When an optimum temperature of between 150 and 250
Celsius on the outer body of the stove is reached push
the slider again further towards the stove to its second
location. This will reduce the secondary air and slow
the rate off enough to allow the stove to operate at its
optimum temperature, where you can see the flames and
slow efficient burning of the logs.
Burning seasoned or kiln dried wood with a moisture
content of under 20% is essential for a smooth transition to
optimum stove temperature.
Lighting and controlling the fire
Warning: This appliance will be hot to touch during operation. Ensure a pair of stove gloves are worn at
all times when operating and refuelling the appliance.

STEP 3
Refuelling
Open the air vent fully for a few minutes before refuelling.
Slowly open the stove door and place one or 2 logs
diagonally onto the fire grate. The door should be left ajar
for a period of around 3 minutes with the air vent slider
open in order maintain flames on a new re-fuel charge.
Once the fire is established close the door and push the
slider to the second location. The appliance is designed to
be used with the door closed.
As a guideline refuel intervals are every 40-50 minutes.
Ensure that the firebox is not loaded above the combustion
inlets on the rear firebrick.
De-ashing
Wood burns best on a bed of ash approximately 25mm (1”
deep). Remove any excess ash from the firebox by using
an ash rake or a small shovel which will allow the ash to
fall into the ashpan below the grate. The ashpan can be
removed by opening the stove door and pulling out the
ash tray beneath the grate.
Place the ash in an ash caddy or suitable metal container.
Do not place hot ash in a container made from plastic or
combustible material.
Ash can remain hot for a long period of time after use,
ensure sufficient time has lapsed before removing. We
recommend de-ashing once a week.
Refuelling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive smoke emission can occur.
Refuelling must be carried out onto a sufficient quantity of glowing embers and ash that the new fuel charge will ignite in
a reasonable period. If there are too few embers in the fire bed, add suitable kindling to prevent excessive smoke.
Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause excess smoke.
Operation with door left open
Operation with the door open can cause excess smoke. The appliance must not be operated with the appliance door left
open except as directed in the instructions.
Dampers left open
Operation with the air controls or dampers open can cause excess smoke. The appliance must not be operated with air
controls or dampers door left open except as directed in the instructions.

Installation instructions
Installation of this appliance must be by a registered Hetas
engineer or approved by your local building control officer.
All local regulations including those referring to National
and European Standards need to be complied with when
installing this appliance.
Connection to top outlet
As standard the stove will be supplied with a top flue
connection. Fire cement or heat resistant rope should be
inserted into the spigot or around the male end of the
pipe to allow a tight fit. A mechanical fixing such as a self-
tapping screw or rivet is required to secure the pipe into
position. While this connection is made we advise to lift
the stove top in order to give the space required
Connection to rear outlet
Unscrew the top spigot and rear plate using a 10mm
spanner and 4mm allen key. Reposition the spigot onto
the rear of the stove and ensure the gasket is fitted
inbetween the body of the stove and the spigot. Insert a
tee piece into the spigot with fire cement or heat resistant
rope and secure with mechanical fixing such as a self-
tapping screw or rivet.

Defra exemption
The Ironwood 5 Wide Stove has been recommended as
suitable for use in smoke control areas when burning wood
logs. This is conditional upon following the wood burning
instructions precisely. Suitable Authorised fuels can also be
used in the appliances in Smoke Control Areas.
See Authorised fuel list:
https://smokecontrol.defra.gov.uk/fuels.php
Further information on the requirements of the Clean Air
Act can be found here:
http://smokecontrol.defra.gov.uk
Your local authority is responsible for implementing the
Clean Air Act 1993 including designation and supervision of
smoke control areas and you can contact them for details of
Clean Air Act requirements.
This stove can be used in Smoke Control Areas by inserting
the 5mm bolt (supplied) to the underside air slider of the
stove (see diagram below).
The Clean Air Act 1993 and Smoke
Control Areas
Under the Clean Air Act local authorities may declare
the whole or part of the district of the authority to be a
smoke control area. It is an offence to emit smoke from a
chimney of a building, from a furnace or from any fixed
boiler if located in a designated smoke control area. It is
also an offence to acquire an“unauthorised fuel” for use
within a smoke control area unless it is used in an “exempt”
appliance (“exempted”from the controls which generally
apply in the smoke control area).
In England appliances are exempted by publication on a
list by the Secretary of State in accordance with changes
made to sections 20 and 21 of the Clean Air Act 1993
by section 15 of the Deregulation Act 2015. Similarly in
Scotland appliances are exempted by publication on a list
by Scottish Ministers under section 50 of the Regulatory
Reform (Scotland) Act 2014.
In Wales and Northern Ireland these are authorised
by regulations made by Welsh Ministers and by the
Department of the Environment respectively.

Your local authority is responsible for implementing the
Clean Air Act 1993 including designation and supervision of
smoke control areas and you can contact them for details of
Clean Air Act requirements.
The Ironwood 5kW Wide Woodburning Stove has been
recommended as suitable for use in smoke control areas
when burning wood logs. The Ironwood 5kW Wide
Woodburning Stove must be fitted with a permanent stop
to prevent closure of the air control slide plate beyond
22.4mm open.
Carbon monoxide alarm
The regulations currently state that “appropriate provision
shall be made to detect and give warning of the release of CO”.
This is covered in Approved Document J of the Building
Regulations that the statutory requirements for installations
of solid fuel appliances. In particular regulation J3 states the
following:
Warning of Release of Carbon Monoxide
J3. |Where a fixed combustion appliance is provided,
appropriate provision shall be made to detect and give
warning of the release of carbon monoxide.
A suitable alarm will have been tested to confirm it meets
the necessary requirements of BS EN 50291:2010, and
activate within the required time when the relevant volume
of CO is detected. The alarm packaging itself will contain
the relevant information, including appropriate Kitemark
reference (if tested by BSI) and also confirmation of the test
method standard, warning of the expected lifetime of the
sensor and where incorporated stating the product includes
an end of life indication.
The general provisions within ADJ and BS8303 ask that the
CO alarm be positioned in a location which provides means
for the immediate detection of CO upon spillage from a
solid fuel appliance. Guidance in ADJ and in BS8303 is that
CO alarms should be positioned as follows;
a) On the ceiling at least 300mm from any wall or, if it is
located on a wall as high up as possible (above any
doors or windows) but not within 150mm of the celling;
and
b) Between 1m and 3m horizontally from the appliance.

What to do in the event of a
chimney fire
In the event of a chimney fire:
1. Close off the air controls immediately.
2. Leave the room, close the door and alert other
people in the house.
3. Evacuate the property and call the fire brigade.
4. Do not re-enter the property until it is confirmed
safe.
Do not use until a registered engineer has inspected the
chimney and appliance to confirm the system is safe and
free from obstruction. Only use genuine Ironwood parts in
the event that stove parts require replacement.Ventilation
For ventilation requirements please refer to Document J.
Many older properties are sufficiently ventilated by
natural leakage of air to provide suitable air supply for an
appliance of 5kW output or less.
Modern building construction has meant that properties
have become more air tight. If the air tightness of a
modern property is less than 5m3 per hour per m2 a
purpose air vent is required for a 5kW rated stove. The
air leakage of a modern house is tested on completion of
construction and a certificate should detail the information
required.
An inadequate air supply can result in a poor combustion.
This appliance requires a constant supply of air to maintain
good combustion.
Extractor fans or cooker hoods must not be placed in the
same room as this can cause fumes to emit into the room.
Care & Maintenance
Annual service
Before the start of the heating season an inspection must
be made and the appliance cleaned as detailed below. It
is important to ensure when any service or cleaning is
undertaken the appliance has had time to fully cool.
Visual checks should be made to ensure the following are
in good condition:
Stove glass and door rope
Side and rear firebricks
Baffle plate
Grate and log retainer
Chimney sweeping
When burning seasoned or kiln dried wood you should
sweep your chimney at least once a year. Ideally the
chimney should be swept before, during and after the
heating season. Sweeping the connecting flue pipe and
chimney keeps the chimney clear from blockages to ensure
that the appliance operates efficiently and safely. Access
to cleaning the chimney is made by removing the firebrick
and baffle plate (see below).
Always check that the sweep is qualified and leaves a
sweeping certificate.

Removing the baffle plate
and firebricks
When sweeping the baffle plate must be removed. This
can be achieved by removing the left hand and right hand
firebrick, as illustrated below, which allows the plate to be
passed through the front opening of the stove. To remove
the rear firebrick the grate is to be moved vertically and
then taken out of the front opening of the fire.
Only use replacement parts supplied or
recommended by Ironwood Stoves.
When removing the firebricks check for any damage and
clean the fire brick with a soft brush. Care should be taken
as the firebricks are fragile. If the brick has a hairline crack
or any damage they must be replaced.

Replacing the glass and door rope
To maintain a safe operation of the stove door any
damaged glass should be replaced immediately. Remove
the door by lifting from the hinges and lay down on a soft
flat surface. Remove the glass fixing strips and fit new glass
into position. Be careful not to overtighten the screws as
this can break the glass. To fit a new door seal remove the
rope and any residue adhesive. Insert rope adhesive into
the channel and replacement rope. Wait approximately 12
hours for the rope adhesive to set before using the stove.
Glass dimensions: 407mm x 310mm
Rope diameter: 10mm (soft rope)
Seasonal use
Over the summer months, when the stove is not in use
remove all ash and soot from within the ash pan and above
the baffle plate. Set the air control to the halfway position
as this will reduce any build-up of moisture in the stove
and reduce any corrosion. In the event that there is rust
on any of the components this can be removed using wire
wool and 2 light coats of stove paint.
After a prolonged period of not using the
appliance check for blockages will need to be
made before re-lighting.

Note that a poor selection of fuel will result in an inefficient burn in the appliance which can further cause:
• Low heat output
• Blackening of stove glass
• Dirty firebricks
• A rapid build up of tar and creosote in the chimney
To ensure a clean and efficient burn only seasoned or kiln dried firewood with a moisture content of less than 20%.
We recommend using‘Ready to Burn’ fuel from an accredited Woodsure fuel supplier.
