3. Pre-Installation
Products of combustion entering the room can cause serious health risks.
This appliance must be fitted in accordance with building regulations and by an
approved HETAS registered installer.
IMPORTANT: Seek specialist advice if the installation is in a dwelling with a thatched
roof.
The flue or chimney system must be in good condition, meet all regulations and work
correctly.
The flue must be inspected by a competent person and passed for use with the
appliance before installation.
The construction of the chimney and connecting flue pipe system must comply with
building regulations.
It is advised that provisions be made for the removal of the appliance without the need
to dismantle the chimney.
The flue or chimney system must be swept and inspected to ensure that it is structurally
sound and free from obstructions
NOTE - The flue must not be shared with any other appliance.
The flue must have suitable access to enable the collection and removal of debris.
Inspect the flue after the appliance has been installed.
NOTE – The smoke pellet gives a fair idea on the draw before fitting the unit but is
no guarantee that the products of combustion will clear from the fire unit after fitting,
so testing is to be done after the installation of the unit by carrying a spillage test.
Ventilation
In certain conditions room sealed appliances require a permanently open dedicated
air supply. This can be provided by means of an air vent in accordance
with Approved Document J, Section 2 (Table 1).
This appliance must have a permanent air vent opening with a total free area of at
least 1650mm².
The permanent air vent/s should be non-adjustable and positioned where they are
unlikely to become blocked. Carefully consider the placement of the vents to ensure
they are placed in areas that are unlikely to cause discomfort from draughts. This
can be avoided by placing vents near ceilings or close to the appliance.
NOTE – Window vents are not considered to be a permanent air supply.

Changing the flue outlets
This appliance is pre-assembled with the flue set to come from the top.
When carrying out a survey assess the situation as to the exit of emissions.
If the flue is to exit the rear of the appliance then an additional blanking plate should be
ordered.
If the flueing is to be fitted to the rear, follow these steps.
1) Remove top panel
2) Remove the bolts holding the flue collar.
3) Using a hacksaw blade cut the lugs off the access plate on the back of the appliance
to gain access to the blanking plate

11
4) Remove the blanking plate via the bolts.
5) Change over the blanking plate with the flue collar and secure. Seal the joint with fire
cement.
6) Ensure the blanking plate (additional part) is bolted to the underside of the removable
top.

12
Connection to chimney
All the stoves have either a top or rear flue outlet adaptor that allows the connection to be
made, to either a masonry chimney or a factory-made insulated metal chimney, using a
connecting flue pipe. The outlet is designed to fit a connecting flue pipe of 150 mm nominal
diameter. The connecting flue pipe and the chimney flue must at no point be less than the
diameter of the stove outlet (or equivalent in the case of a square section chimney).
All joints in the appliance to chimney flue connection must be sealed using approved
materials.
If the stove is fitted in place of an open fire then the chimney should be swept one month after
installation to clear any soot falls which may have occurred due to the difference in
combustion between the stove and the open fire.
IMPORTANT INFORMATION FOR BURNING WOOD IN A SMOKE CONTROL AREA
It is an offence to burn wood or other non-authorised smokeless fuels in a smoke control area
on an appliance that is not exempted for burning the non-authorised fuel. Currently Chesney’s
8 Series Stove Collection are not exempt appliances.
Hearths
The area where the appliance is to be fitted must have a suitable load-bearing capacity for
both hearth and appliance.
The appliance must stand on a non-combustible hearth.
Check building regulations.
If you are using an existing hearth check it complies with the relevant construction regulations
and is at least the minimum sizes specified.
A suitable clearance is required around the stove to enable the use of all levers, allow for
maintenance and for air to circulate around the appliance.
Maximum Hearth Temperature 70.3°C (obtained durin g tests with Ancit)

13
6. Commissioning
Before Lighting
Ensure that all parts are in position such as firebricks, baffles, grate, riddle plate, fuel retainer
bar etc.
All castings, joints and door seals must be checked for soundness.
Check that the riddling lever, fuel selector lever and the air flow bar operate smoothly.
Flue draught
When commissioning the installation it may be necessary to carry out a flue draught test. The
ideal flue draught is 12pa.
Insufficient or excessive flue draught can lead to poor combustion, blackened glass and
reduced efficiency. These can cause damage to the appliance.
Carrying out smoke tests
Heat up the flue system for about 10 minutes using a blowlamp or similar.
Open the air controls and place a smoke pellet in the centre of the riddle plate then close the
appliance door.
Check the appliance and flue for the correct withdrawal of the smoke.
If the tests fail then the flue system, ventilation and appliance must be re-checked and
amended.
If it passes then the appliance can be lit for further tests.
Light the appliance and increase the temperature slowly, ensuring there are no combustion
products entering the room. Also check for emissions in other parts of the dwelling where the
flue / chimney routes including loft areas.
LIGHTING THE APPLIANCE FOR THE FIRST TIME
When lighting the appliance for the first time, the materials (i.e. paint, sealants etc.) may give
off a smoke haze and an unpleasant odour. This is quite normal and will disappear after a
few lightings. During this period, keep the room well ventilated to keep the room free of
odours and fumes.
We recommend that you have 2 or 3 small fires before operating the stove at full
temperature. This will allow the paint to cure.
Once the appliance reaches the operating temperature carry out a further spillage test by
opening the door, this time checking around the door opening using either a smoke match or
smoke pellet.
If excessive spillage occurs allow the appliance to cool down and re-check the flue and
ventilation system.
If the appliance, flue system and ventilation work correctly move on to briefing and handover
to the customer.

14
7. Briefing and handover to the customer
Explain to the user the full operation of the appliance.
Warn the customer that the fire unit will give a temporary odour caused by the paint ‘curing’.
This is normal running in of the unit and will disappear after a short period of use.
Inform the user not to use the appliance as an incinerator and explain the importance of using
appropriate fuels.
Advise the customer not to over-fire the appliance.
Inform the customer that it is recommended to regularly clean and maintain the appliance and
to check for damage to firebricks, seals, lever operations or any irregularities and if in any doubt
seek advice.
Brief the customer that eventually stove paintwork may need a light re-spray occasionally after
a seasons use, and that stoves painted in a lighter colour are more likely to require this and to
ensure that the appliance is off and cool and the appropriate safety guidelines are followed
when carrying out such work. Touch-up spray is available from most Chesney’s stockists.
Advise the customer that it is recommended to have the appliance and flue system serviced on
an annual basis.
Warn the user that the appliance is not supplied with a fireguard but that the use of such is
recommended for the protection of young children, the elderly or infirm and in the course of
normal use and that any fireguard used conforms to standards.
Advise the user not to stand too close to the appliance for prolonged periods of time, loose
clothing is particularly at risk of burning, due to the heat produced from the appliance and flue.
Advise the user against placing combustible materials directly above or in front of the appliance.
Ensure the installer details are filled in.
Give the copy of the installation manual to the customer, and advise the user to keep it handy
for future referencing and maintenance.

15
8. Servicing and Maintenance
It is important that this appliance is properly installed and regularly maintained.
Periods of Prolonged Non-Use
If the stove is to be left unused for a prolonged period of time then it should be given a
thorough clean to remove ash and unburned fuel residues. To enable a good flow of air
through the appliance to reduce condensation and subsequent damage, leave the air controls
fully open.
The chimney system should be checked for blockage after periods of prolonged shut down.
If the appliance is emitting fumes into the room it is strongly advised that the appliance and
the chimney / flue system is checked over for blockages and that all seals are intact.
Before carrying out fitting, servicing or maintenance works on the appliance or flue / chimney
system ensure that the surrounding area is protected so as not to damage the property.
It is advised that the flue is checked regularly and that the flue is swept at least once a year.
It is best to carry out an annual service at the end of a heating season.
Clean ash / soot build up and inspect for any damage and wear and tear and repair if
necessary.

Paintwork
It is generally accepted that stove paintwork may need a light re-spray occasionally after a
seasons use, stoves painted in a lighter colour are more likely to require this.
Touch-up spray is available from most Chesney’s stockists.
Ensure that there is adequate ventilation and that areas to be sprayed are clean and dry. Make
sure that all parts and the surrounding area that do not require paint are properly masked up.
NOTE – Only re-spray when the appliance is off and cool following the safety guidelines when
carrying out such work.
Cleaning the glass
The appliance is designed to keep the glass from badly staining provided the solid fuel is of
good quality and is burned in the correct manner but sometimes due to the nature of the burn,
tars and creosotes may stain the glass.
If the glass is dirty check that fuel selector lever is set correctly.
To clean the glass use a stove glass cleaner.
Do not clean the glass if the glass is still hot.
Ensure the glass is cool before applying glass cleaner.
Use an appropriate stove glass cleaner following the instructions on the glass cleaning.
Changing the door glass
If the glass is damaged resulting in cracks or breaks do not use the fire until the glass is
replaced.
Glass staining may be caused by too low a burning temperature, poor quality fuels or
incorrect use of the air flow lever.
If the glass is badly stained and the stains cannot be removed this will not damage the
appliance but may hinder the inspection of the burn. Replacement of the glass is advised if
you are unable to inspect the burn.
Removal of the glass panel
Wear appropriate safety equipment and take care when removing the glass panel.
On changing the glass it is advised that the glass seal is also renewed to ensure a good seal.
Remove the glass retaining bracket via the two screws.
Gently push the glass out on the retaining bracket side and pull the glass out of the retainer.
Replace in the reverse order.
