Installation Instructions
READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION
These instructions cover the basic principles to ensure satisfactory installation of the stove, although
detail may need slight modification to suit particular local site conditions. In all cases the installation
must comply with National and European Building Regulations, Local Authority Byelaws and other
specifications or regulations as they affect the installation of the stove.
Health and Safety Precautions
Handling
Adequate facilities must be available for unloading and site handling.
Fire Cement/Glue
Some types of fire cement/glue are caustic and should not be allowed to come into
contact with the skin. In case of contact, wash immediately with plenty of water.
Asbestos
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the
course of installation then please seek specialist guidance and use appropriate protective
equipment.
Metal Parts
When installing or servicing this stove, care should be taken to avoid the possibility of
personal injury.
Please note:
Any white deposits on the stove joints are caused by humidity reacting with the joint
sealant. These deposits may be brushed off and, if necessary, blackened with a
proprietary stove polish.
Important Warning
This stove is suitable for use in a standard 16” solid fuel fireplace opening.
This stove is only suitable for use in a fireplace and/or chimney that has
been fitted for use with solid fuel. The fireplace back panel and hearth
must have the necessary expansion joints and back filling for solid fuel
use. This stove must not be installed into a chimney that serves any other
heating appliance.
The floor on which the appliance is installed must be of adequate load bearing capacity.
If it is not, suitable measures (e.g. a load distribution plate) must be employed.
No purpose provided ventilation is required for stoves rated under 5KW. For each KW
above 5KW, 550 sq mm of fixed ventilation is required – i.e. a stove rated at 8KW would

require 3 x 550 sq mm = 1650 sq mm of fixed ventilation. If more than one appliance is
installed in the same room, the ventilation requirements for each appliance must be added
together. If ventilation grilles are installed ensure they are free from any potential
blockage.
There must not be an extractor fan fitted in the same room as the stove as this can cause
the stove to emit fumes into the room.
This appliance must not be used as an incinerator.
Installation
Chimney
The chimney height and the position of the chimney terminal should conform to Building
Regulations. Check that the chimney is in good condition, dry, free from cracks and
obstructions. The diameter of the flue should not be less than 150mm and not more than
200mm. If any of these requirements are not met, the chimney should be lined by a
suitable method. The chimney must be swept before connection to the stove.
Where the chimney is believed to have previously served an open fire installation, it is
possible that the higher flue gas temperature from the stove may loosen deposits that
were previously firmly adhered, with the consequent risk of flue blockage. It is therefore
recommended that the chimney be swept a second time within a month of regular use
after installation. If you have any doubts about the suitability of your chimney, consult
your local dealer/stockist.
If there is no existing chimney then either a prefabricated block chimney or a twin-walled
insulated stainless steel flue to BS 4543 can be used. These chimneys must be fitted in
accordance with the manufacturer’s instructions and Building Regulations.
Flue Draught
A flue draught of minimum 12 Pa to a maximum 25 Pa is required for satisfactory
appliance performance. The flue draught should be checked under fire at
high output and, if it exceeds the recommended maximum, a draught stabiliser must be
fitted so that the rate of burning can be controlled and to prevent overfiring.
Connection to the Chimney
It is essential that all gaps between the stove and fireplace fascia or chimney-flue are
sealed and made airtight. This appliance is not suitable for installation in a shared flue
system.
The chimney must be accessible for cleaning. This insert stove should be removed at
least once a year and cleaned.
Material Clearances
All non-combustible walls closer than 400mm to the stove should be at least 75mm thick.
In all instances the back wall of the fireplace recess and the hearth should be made of
non-combustible material. Allow an apron of at least 300mm at the front of the stove and
150mm on either side. The hearth on which the stove is to be placed should not be less
than 125mm thick and should be in accordance with the current building regulations.

Safety Distances from Combustible Surfaces:
Side/Front Top
HD Insert 4KW Stove 275mm* 275mm
*The HD Insert 4KW stove can be situated 200mm from the side of a wooden fireplace
mantel if the mantel is flush (or less deep) with the front of the appliance
Commissioning and Handover
Upon completion of the installation, allow a suitable period of time for any fire cement
and mortar to dry out. A small fire may then be lit and checked to ensure the smoke and
fumes are taken from the stove up the chimney and emitted safely to atmosphere. Do not
run the stove at full output for at least 3 – 4 days.
On completion of the installation and commissioning, ensure that the operating
instructions and operating tools for the stove are left with the customer. Ensure to advise
the customer on the correct use of the appliance with the fuels likely to be used on the
stove and warn them to use only the recommended fuels for the stove.
Advise the user on what to do should smoke or fumes be emitted from the stove. The user
should use a suitable fireguard in the presence of children, aged and/or infirm persons.

Operating Instructions
This appliance is not suitable for use in a shared flue.
This appliance should not be operated with the doors open.
This appliance is capable of intermittent operation.
Aerosol Sprays
Do not use an aerosol spray on or near the stove when it is alight.
Air Controls
This stove has been designed to burn clean and efficient. If used correctly this stove will
burn far more efficiently than normal with the obvious notable features of CLEAN
GLASS. Never clean glass when stove is hot. Always use stove glass cleaner which is
available from your stove retailer.
However, for this product to work properly it must be used correctly.
It is essential that the stove has an adequate air supply for combustion and ventilation.
The primary and secondary air inlets must be kept clear from obstruction.
Note:
The secondary air control is open when pushed to the right.
Warning! This appliance will be hot when
In operation and due care should be taken
When operating the controls.
Air Controls
Primary Air
Primary air is controlled via the two rotary air controls on the bottom of the door.
This provides a conventional air draught to the bed of the fire. The primary air intakes
can be adjusted to give the best possible results when burning different fuels.
Secondary Air
The cast iron stove is fitted with a sophisticated “air wash” system. This secondary air
supply to the stove is controlled through a slider assembly located at the top of the stove.
Grate

Your HD Insert Stove is fitted with a removable cast iron grate. It is important to de-ash
regularly, to ensure that the primary airflow is not impeded, as a build-up of ash can
damage the cast iron grate.
Ashpan
It is essential that you empty the ashpan regularly. Use the “T” end of tool to lift the
ashpan out of the stove.
Notes on burning Wood
With a full load of wood, the stove will need to be refuelled approximately every 1.5
hours. Wood can be stacked higher in the stove than solid mineral fuel but care must be
taken that logs do not touch the baffle.
Wood burns most efficiently with the primary air controls closed and the secondary
control partially open. Moving the secondary control will control the burn rate of the
stove.
Note – primary and secondary air is needed to light the stove, see section entitled
‘Lighting the Stove’.
Burn only dry, well-seasoned wood, which should have been cut, split and stacked for at
least 12 months, with free air movement around the sides of the stack to enable it to dry
out. Burning wet or unseasoned wood will create tar deposits in the stove and chimney
and will not produce a satisfactory heat output. Do not use liquid fuels in this appliance.
Size of Fuel
Maximum Log Size
HD Insert Stove 4KW 200CM
Notes on burning Solid Fuel
Before refuelling, it is important to de-ash the grate. When burning solid fuel, the ash pan should
be emptied at least twice a day or 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 grate as this will greatly shorten its
life.
When lighting the fire, set the secondary air setting to one quarter open position. Set the primary
air setting to the fully open position. Light in the normal manner with paper and kindling, or use a
fire lighter.
When the fire is well alight regulate the burning rate by adjusting the setting on the primary air
inlet control. The air wash can be opened sufficiently to keep the door glass clean
Approved smokeless coal is recommended for use in this appliance. At first you may find it
helpful to try several fuels to find the most suitable. If you are unable to obtain the fuel you want
ask your supplier, or an approved fuel distributor to suggest an alternative.
Take care to only burn good quality fuels in order to obtain the greatest efficiency and to maintain
the life of the appliance.
Lighting the Stove
We recommend that you have two or three small fires before you operate your stove to its
maximum heat output. This is to allow the paint to cure in steadily and to give a long
service life of the paint finish. During this curing in process you may notice an unpleasant
smell. It is non-toxic, but for your comfort we would suggest that during this period you
leave all doors and windows open.
First, load the fire with starting fuel, i.e. paper, dry sticks and/or firelighters in the mode
chosen, either wood or solid mineral fuel.

Light the fire at the base leaving all air controls open. Allow the fuel to reach a steady
glow and build the fire up gradually. Once you have a good fire established across the
grate bed, further fuel can be added as required.
Shutting Down
In order to shut down the stove, close the primary air controls, then close the secondary
air slider by moving the handle all the way to the left. If the controls are left in this
position, the fire will be starved of air and will go out. If you want to revive the fire it is
recommended that the primary air controls are open first, then open the secondary air
slider.
Warning! - The stove will remain hot for a considerable time after the fire has been
extinguished.
Warning! - Petroleum coke fuels, household waste or liquid fuels must not be burnt on
this appliance.
Should any difficulties arise over fuel quality or suitability, consult your local approved
fuel merchant.
Safety Notes for your guidance
FIRES CAN BE DANGEROUS – Always use a fireguard in the presence of children,
the elderly or the infirm.
DO NOT OVERFIRE – it is possible to fire the stove beyond its design capacity, this
could damage the stove, so watch for signs of overfiring – if any part of the stove starts to
glow red, the fire is in an overfire situation and the controls should be adjusted
accordingly. Never leave the stove unattended for long periods without first adjusting the
controls to a safe setting – careful air supply control should be exercised at all times.
Any unauthorised modifications of this appliance will render the guarantee null and void
and could be potentially dangerous. Replacement parts should only be sourced from
approved dealers
WARNING – FUME EMISSION
Properly installed and operated, this appliance will not emit fumes. Occasional fumes
from de-ashing and refuelling may occur. Persistent fume emission must not be tolerated.
If fume emission does persist, then the following immediate action should be taken: -
1. Open doors and windows to ventilate room
2. Let the fire out, or eject and safely dispose of fuel from the appliance.
3. Check for flue chimney blockage and clean if required.
4. Do not attempt to re-light the fire until the cause has been identified and
corrected.
If necessary, seek professional advice.
Important! – Do not fit an extractor fan in the same room as this appliance.
IN THE EVENT OF A CHIMNEY FIRE
•Raise the alarm to let others in the house know.
•Call the Fire Brigade
•Reduce the appliance-burning rate by closing all air controls.
•Move furniture and rugs away from the fireplace and remove any nearby
ornaments.

•
Place a fireguard or spark guard in front of the stove.
•Feel the chimneybreast for sign of excessive heat.
If the wall is becoming hot, move the furniture away. Ensure that the Fire Brigade can
gain access to your roof space in order to check this area for signs of fire spread.
Frequently Asked Questions
1 Do I need a fireplace suitable for solid fuel?
The HD Insert Stove can only be installed in a fireplace that is suitable for burning solid
fuel.
2 Do stoves require a chimney?
All of our multi fuel and wood burning stoves require a suitable chimney or
professionally installed flue system.
3 How do I clean the chimney?
You will require a chimney sweep to clean the chimney. It is highly recommended that
the chimney is swept annually.
4 Who should install my stove?
HD Insert Stoves want you to enjoy the maximum performance from your Stove
products. To ensure this, it is essential that they are installed correctly.
We strongly recommend that your HD Insert Stove is installed and regularly maintained
by a qualified heating engineer.
5 How do I regulate the heat output?
Each stove will have spin valves, which will allow you to easily regulate the heat output.

6 What warranty policy do I get?
HD Insert Stoves will replace, free of charge, any working part that fails (under normal
operating conditions) within 12 months of purchase. Consumables such as glass or stove
rope are not guaranteed.
A call out charge will apply if our engineer attends any stove problem that is n
ot
related to product failure.
7 Where can I get spare parts?
Your local HD Insert Stove retailer will be pleased to supply spare parts and to provide
any other information you require. (Only use replacement parts recommended by the
manufacturer).
8 Can the doors be left open while burning?
For safety and heat efficiency the doors should remain closed at all times except for
ignition, de-ashing and loading the firebox.
9 Why is the stove smoking when lit?
A smoking stove can be caused by a flue with back draught problems. A qualified fitter
should complete a smoke test prior to fitting the stove to ascertain the integrity of the
flue. Alternatively, the insert stove may smoke if it is not sealed correctly to the fireplace
fascia.
10 Why should I “Run in” my stove?
To begin, light a series of small fires over a period of a few days to allow the paint finish
to cure. The stove is finished with a heat resistant paint and this can be cleaned with a
soft brush. Do not clean whilst the stove is hot; wait until it has cooled down. The finish
can be renovated with proprietary stove paint
If the stove is not “run in” correctly, this may cause the paint to discolor and flake.
11 What is Over Firing?
Your stove should never be used in a manner to cause over firing. Over firing can be
caused by over loading the stove with fuel, and with primary controls open. If any part of
stove glows "red" your stove is over firing and your draught control should be adjusted to
restrict airflow to stove. Over firing can cause permanent damage to the appliance which
is not covered by warranty.
