3.2 Health and Safety
Please consult Health and Safety Guidelines for advice on handling heavy and/or large
items.
4 Recommended fuels
4.1 Wood
As a natural and renewable fuel, wood is the first choice for burning, however burning
wood requires a little effort and planning.
Any type of wood is suitable (though hardwood is preferable) provided it is well
seasoned and has a moisture content below 20%. This usually implies that the timber
has been suitably stored to allow moisture to evaporate for at least 9 months in the case
of soft wood, and at least 24 months in the case of hard wood. We recommend using
dry logs with a diameter of 5-8cms and length of 20-25cms.
If, when burning wood, you see signs of sticky tar inside the appliance or chimney, your
wood is ‘green’ or too wet and requires further seasoning. An electronic moisture meter
can be obtained in order to determine the moisture content of your wood fuel. Wet wood
must not be used as this will greatly contribute to the creation of tar and creosote which
may, in extreme cases, run down the chimney in liquid form. This will seriously damage
both the chimney and the appliance and increase the risk of a chimney fire.
DO NOT BURN Bituminous house coal or petroleum coke in this appliance.
DO NOT BURN Any form of plastics in this appliance.
LAGOM Stove User Guide

5 Before using your stove
Arada stoves are designed to be operated with the fire door(s) closed at all times, apart
from refuelling (when alight) or cleaning (when cold).
Never leave the appliance unattended for an extended length of time with the
door open.
Prior to lighting the stove for the first time, please check with the installer that:
 Installation and all building work is complete. (Refer to the installation guide.)
 The chimney is sound, has been swept and is free from obstruction.
 Building Regulations and any local by-laws have been followed during installation.
 All firebox liner panels and throat plate are in place.
 The chimney draw has been checked and is within specification (between 0.1mb to
0.2mb, or 10-20 pascals). This ensures your stove will operate predictably and
efficiently.
 A Carbon Monoxide detector is correctly installed in the same room as the
appliance.
 Suitable provision for combustion and ventilation air, depending upon Building
Regulations have been undertaken by the installation fitter.
 Consideration must be given for the need for extra ventilation if another heating
source needing air is to be operated simultaneously. If an extraction fan is proposed
to be fitted to a connecting area of the house, after the stove has been installed,
professional advice should be sought from a qualified engineer.
Ensure that you have read and understood these instructions before lighting the fire.
Our YouTube channel, www.youtube.com/user/aradastoves features a collection of
videos designed to help you get the best from your Arada stove.
Always wear suitable protective fire gloves when refuelling your stove, such as the Arada
hot glove supplied with your stove. Always keep the hot glove away from naked flames
and sparks when re-fuelling the appliance.
We recommend that you light a small fire for the first few days of use to cure the paint
and allow the castings to relax.
You may hear your stove produce clicking or ticking noises whilst it heats up or cools
down. This is completely normal and is produced by the expansion and contraction of the
steel components in your stove when its temperature changes.

6 Air inlet controls
6.1 Air Inlet
Your stove requires air to function. This enters the appliance via the circular duct on the
under side of the stove. Depending upon installation, this circular duct can also act as the
connection point for the direct air feed / ducting requirements.
NOTE : DO NOT COVER OR PARTIALLY OBSTRUCT THE AIR INLET OPENINGS FOR
THE APPLIANCE.
6.1.1 Air control location
The air control regulates the air entering the fire box chamber controlling the rate of burn.
This control is situated below the fire door in the middle of the stove when facing the front of
the stove.

7 Lighting your stove
7.1.1 Smoke control areas
Please check whether your dwelling is located in a smoke control area before installation or
use. Please check with your local authority or https://www.gov.uk/smoke-control-area-rules.
7.1.2 Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded. Overload-
ing can cause excess smoke. Please see Technical Data section in this manual.
7.1.3 Operation with door open
Operation with the door open can cause excess smoke. The appliance MUST NOT be
operated with the appliance door open except as directed in the instructions.
7.1.4 Dampers / Air controls left open
Operation with the air controls or appliance dampers open can cause excess smoke. The
appliance must not be operated with the air controls, appliance damper or door(s) left open
except as directed in these instructions.
7.2 Burning wood
When wood is burnt, it is in fact the volatile gases released from the wood that burn and
this requires a good supply of air coming from above the fuel. For this reason we open the
air inlet fully while igniting the stove then reduce this once the burn is well formed. As
much as 40% of the heat from burning wood is obtained from secondary combustion and
this can be severely hampered by air entering the fire box from below the fuel.
1) Set the fire by placing several layers of dry kindling wood into a criss-cross grid
pattern on top of the grate. The use of two or three fire lighters may assist in lighting
the kindling.
2) Fully open the air control and light the fire-lighters and/or kindling wood.
3) After the kindling has caught alight, you should almost close the fire door leaving it
ajar by about 10mm. This will aid flue draw during the initial lighting of the fire.
4) The flue temperature and draw should be established after five minutes and the
kindling reduced to form an ember bed. Carefully load the stove with well seasoned
wood and fully close the fire door.
5) After ten minutes, fully close the air control to control the burn rate and maintain
clear glass, typically by reducing to approximately half open.
BK 746 Specific Page 16
LAGOM Stove User Guide

7.3 Refuelling
In order to prevent smoke escaping into the room when refuelling, please follow the
procedure below:
Approximately 5-10 seconds before opening the fire door, open the air control fully and then
only slightly open the fire door. Wait a few seconds for the exhaust gas to get sucked into
the chimney and only then fully open the door. When opening the fire door, special
attention must be paid to the danger or hot fire-embers falling out.
After refuelling, close the door again. When the fuel ignites with a solid flame, return the air
control to the previous burning position. The amount of fuel should correspond to an hourly
consumption value for the stove (see the Technical Data).
Overheating/firing can permanently damage the stove construction.
To prevent exhaust gas escaping into the room during refuelling, always refuel onto a
glowing ember bed.
7.4 Operation during the transition period
The chimney draft (sucking exhaust gas from the fireplace stove) might be weaker during
the transition period, i.e. when the outside temperature is higher than 15oC, during rainy
and humid days or wind gusts. During this period the fireplace stove should be operated
with the minimum possible fuel so that the fire, as well as the chimney draft, is improved by
opening the air intake.
Tip: During this period a so-called atmospheric plug can be created in the chimney mouth
due to the draft conditions. The plug can cause smoke to escape into the room when
lighting fuel. We recommend letting a piece of paper burn down, preferably in the upper
part of the combustion chamber, before lighting the kindling. This seemingly negligible
smoke is enough to break through the atmospheric plug. Afterwards you can freely light
paper and be sure that even a humid chimney is clear.
7.5 Warning - Fume / Smoke emissions
Properly installed with a suitable flue or chimney, operated and maintained correctly,
this appliance will not emit fumes into the dwelling. Occasional fumes when
de-ashing and refuelling may occur. However, persistent fume emission is
potentially dangerous and must be investigated by an approved / registered installer.
BK 746 Specific Page 17
LAGOM Stove User Guide

STOP USING THE APPLIANCE IF YOU SMELL FUMES OR SEE SMOKE
ESCAPING.
If fume emission does persist, the following immediate actions should be taken:
 Open doors and windows to ventilate room.
 Let the fire die or extinguish and safely dispose of fuel from the appliance.
 Check for flue or chimney blockage, and clean if required.
 Seek expert advice from your approved installer.
 Do not attempt to re-light the fire until the cause of the fume emission has been identi-
fied and corrected.
7.6 Refuelling on to a low fire bed
If there is insufficient burning material in the fire bed 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 for ignition to prevent excessive
smoke.
7.7 Typical burn for nominal output
To perform the most efficient burn at the nominal rated output please consult the
specification table at the rear of this manual.
Please note that many factors can effect the nominal output, so the stated weights of fuel
(Seasoned hard wood) are a guide, which is a representation to laboratory test burn
conditions.

8 Further information for all stove owners
8.1 Reduced burning (Slow Combustion)
When wood is burnt slowly in a closed appliance (e.g.: air controls at the minimum
setting), it produces moisture and tar which will create condensation and deposits in the
chimney. This effect can be minimised by burning hard for a short period, fifteen to twenty
minutes twice a day.
To avoid chimney problems, your appliance should not be burnt at a reduced burn rate
without a period of fast burning. Fast burning is when the stove is burnt with a ’lively flame’
and a higher temperature. We strongly advise against stoking the fire with wood and
reducing the air inlets before leaving the stove to extinguish (perhaps when retiring to bed)
as this can lead to a cooling of the stove and flue, resulting in incomplete combustion,
sooty deposits and high levels of pollutant gases released into the environment.
8.2 Over firing
DO NOT over fire your appliance. Firing the stove at maximum for prolonged
periods may result in over-firing. If the chimney connector or casing glows red the
appliance is being over-fired and this may result in a chimney fire. Other signs include
warping and a red-oxide colouring will demonstrate the over heating of internal parts; body
paint which has turned dusty white is also indicative of such use.
8.3 Chimney fires
Used in the correct manner, with the correct fuel and regular maintenance a chimney fire
should never occur. However in the event of a chimney fire, the following procedure
should be actioned without delay:
 Call the fire service—DIAL 999
 Immediately close all of the air inlet supplies on the appliance to reduce the air
supply to the stove.
 Move items of furniture and combustibles away from the surrounding area of
the stove, to reduce the risk of fire and allow access for the fire service.
 Ensure access to the loft space is available.
 Evacuate the property.
8.4 Periods of non-use (summer months)
Please ensure that your stove is left clean and moving components are well lubricated
with a water repelling corrosion inhibitor for the summer months (during periods of
prolonged non-use). If possible store the throat plate outside the stove. Check all movea-
ble components at regular intervals to ensure they are moving freely. Allow air movement
through the stove by opening the air inlet control to about half way, open or leave the door
ajar. This will allow a free flow of air through the appliance thus preventing moisture and
condensation forming inside the stove and chimney. This preventative maintenance will
ensure your stove stays in the best condition for the coming winter months.

LAGOM Stove User Guide
8.5 Ash removal
The ash pan should be emptied when the level of ash reaches the top of the ash pan. On
no account should the ash be allowed to build up to touch the underside of the grate, as this
will greatly reduce the life span of the grate.
To remove the ash pan ALWAYS USE the supplied hot glove -
 Open the door of the stove, pausing briefly when ajar so as to allow the fire to adjust
to the increased air supply.
 Locate the central handle on the ash pan with one hand.
 Carefully withdraw the ash pan from the ash pit chamber.
 Empty the ash into a suitable metal container. Replace the ash pan into the stove,
 reversing the above procedure and close the fire door.
8.6 Replacement parts
Genuine replacement spare parts can be obtained from www.aradastovesandspares.com
You can find a complete list of spares and consumables such as liners, grate and throat
plates, as well as items to enhance its visual appearance and efficiency such as stove paint
and rope kits.
It is worth noting that the fitting of non-official Arada parts to your stove will invalidate its
guarantee.
8.7 Classification
All Lagom stoves are classed as intermittent operation. Thereby meaning, to give nominal
rated output, you will have to refuel a minimum of 45min for wood, as stated in EN
13240:2011 +A2:2004.
Warning: The ash can be very
hot. Care must be taken not to burn
hands or household objects with
falling embers—ALWAYS USE
THE HOT GLOVE SUPPLIED.
Empty only into a metal container.
Even if the ash appears cold, red-
hot embers may be concealed and
could easily start a fire or cause an
injury.
