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 Northern Ireland appliances are
exempted by publication on a list by
the Department of Agriculture,
Environment and Rural Affairs under
Section 16 of the Environmental Better
regulation Act (Northern Ireland) 2016.
In Wales appliances are exempted by
regulations made by Welsh Ministers.
• The Tenbury (T400Eco)

Operating your stove
Using your appliance for the
first time
• To allow the appliance to bed in, and
fixing glues and paint to fully cure, only
fire the appliance using kindling and just
get hot for at least three fires.
• Before lighting the next small fire please
allow the appliance to return back to
room temperature.
• During these first small fires you may
experience a haze and unpleasant smell
as the paint cures, do not touch the paint
and keep the room well ventilated.
Please note that during the first firing, we
recommend a small fire is lit and that you
slowly increase the temperature to enable
the various parts to expand normally.
You may also experience fumes and a
haze being given off by the stove during
the first firing and possibly for the next
couple of firings as the paint cures. This is
normal but please ensure that the room is
well ventilated during this period.
The appliance should not be operated in
mild weather with smokeless fuel. Under
certain weather circumstances e.g. fog the
chimney will not draw sufficiently and
could cause asphyxiation. Either await
better weather conditions or burn wood
only.
In the rare event of a malfunction due to
overheating or a chimney fire, the air slides
should be shut down completely and the
fuel allowed to burn out. In the event of a
chimney fire, once the air slides have been
Always ensure that the ash draw is fully located before operation of
the appliance

chemically treated and will pollute the
atmosphere and possibly overheat the
appliance.
Housecoal or Bituminous coal: these
fuels will soot up the airways of the stove
and possibly overheat the appliance.
Petroleum Based Coke: over 20%
content - this will overheat the appliance
and possibly damage the unit.
Liquid fuels
Paraffin fire lighter blocks: these can
cause damage to the glass of your
appliance.
Always check with your dealer or directly with
the manufacturer as using the incorrect fuel
may invalidate your guarantee and damage
your appliance.
Instructions for use with wood
• Please ensure that flat steel grate top is
in place if burning wood logs, this will
help to maintain a bed of ash and allow
for correct combustion of the wood logs.
• Open the secondary air slider to the left
hand side of the door, and open the
primary air slider to the right hand side of
the door by fully pushing the levers
inwards.
• Lay firelighters or rolled up newspapers
on the grate and add a small amount of
kindling wood to the top. Place 1 or 2
small logs on the top.

primary air slider to the right hand side of
the door by fully pushing the levers
inwards.
• Lay firelighters or rolled up newspapers
on the grate and add a small amount of
kindling wood to the top. Place a small
quantity of smokeless fuel on top.
• Light the newspaper or firelighters using
a long taper and push the door closed
but do not engage the locking handle
fully.
• When the fire is burning fiercely, after a
couple of minutes add more smokeless
fuel and close the door.
• When the fire has become established,
close the secondary air by 50%, to the
left hand side of the door, by pulling the
lever outwards.
• The burning rate can be altered by
moving the primary air slide, to the right
hand side of the door - pull the lever
outwards to close down and push the
lever inwards to increase the burn rate.
• Care should be taken to ensure that the
firebox is not overfilled with smokeless
fuel - it should be no higher than the log
guard.
Re-fueling
When refueling the stove always refuel
onto a bed of hot embers, fully open the
secondary and primary air controls until
the new fuel is well alight, before adjusting
the air controls for the desired setting.
If there is insufficient burning material in
the firebed to light a new fuel charge,
excessive smoke emission can occur.
Refueling 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
Never overload the stove - it will work very
well with two medium sized logs. The
amount of fuel specified in this manual
should not be exceeded, overloading can
cause excess smoke.
Glass
Never operate the appliance if the glass
panel is broken or cracked. This can cause
the appliance to overfire, which may
damage the appliance and flue system
and may cause a danger to persons and
property. Only use once the glass is
replaced and the sealing gaskets checked
for integrity, only replace with a
manufactures approved glass.
Operation with door left open
Operation with the door open can cause
excess smoke and overfiring of the
appliance. 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
appliance dampers open can cause
excess heat within the appliance. The
appliance must not be operated with air
controls, appliance dampers or door left
open except as directed in the
instructions.
Never leave the stove unattended
until the new fuel is well alight.
Persistent fume emission is
dangerous and must be
investigated.
If fume emission persists, open doors and
windows to ventilate the room and let the
fire die out. Have the chimney inspected
for blockages and clean if required. Do not
relight the fire until the cause has been
found. We recommend that you seek
professional advice.
This appliance has been designed to be
burned with the door closed at all times
other than when refueling.
It should not be operated as an open fire.
Typical refueling intervals for wood is 1
hour and smokeless fuel is 2 hours.

Tenbury T400 install manual NEW 2020-0320-7 16/03/2020 14:05 Page 11

Maintenance
Daily Maintenance
• The grate should be cleaned regularly
and the ash pan emptied daily.
Never allow the ash in the ashpan to
overfill allowing ash to be in contact
with the underside of the grate.
This will overheat the grate and cause
premature wear and distortion.
• The glass can be cleaned using a soft
damp cloth or a stove glass cleaner
(available from your local stockist)
• Do not clean the glass of your stove
with abrasive cleaners or scratch pads
as this may damage the surface of the
glass causing it to weaken and wear
prematurely.
• Never allow the door gasket to
become wet when cleaning the glass,
this will deteriorate the gasket
prematurely.
Periodic Maintenance
• The chimney should be swept at least
once a year together with the flue pipe
connection. Care should be taken to
ensure that there is not a build up of
soot on the baffle and in the airways of
the appliance.
• If the appliance has not been operated
for long periods, the flue should be
inspected and swept before use to
ensure there are no blockages within
the flue.
• The internal vermiculite panels of the
appliance should be checked regularly
for soundness. If any wear and tear is
found, we recommend these parts are
replaced immediately.
• Check the rope door seals are intact
and are not worn. These should be
replaced on an annual basis to ensure
the correct operation of this appliance.
• Is advisable as part on the periodic
maintenance of your appliance to
lubricate the moving parts of your
stove i.e. handle, air sliders, door
hinges, with a suitable high
temperature lubricant this will ensure
the correct operation of your
appliance.
• It may be necessary to adjust to
tension of the door closing mechanism
during the lifetime of the appliance as
the sealing rope will compress over
time, this is achieved by the adjusting
the bracket on the body of the stove
to the required tension.
Summer
• When the stove is not going to be
used for long periods e.g. the summer
months, we recommend that you keep
the air slides fully open and the door
slightly ajar if possible. This will help to
prevent condensation which may in
turn lead to internal corrosion of
component parts.
We recommend that the appliance is serviced
annually by a competent engineer to ensure it’s
continued safe operation.

Tenbury T400 install manual NEW 2020-0320-7 16/03/2020 14:05 Page 12

Refractory internal panels
During the normal operation of your
ACR stove, the refractory panels will
experience heating and cooling.
Sometimes minor hairline cracks can
occur. All ACR stoves have a steel or
cast iron structure behind the panels
and therefore even if the cracks get
larger, the stove will still operate safely.
It is advisable to replace the internal
panels when:
• The cracks are greater than 3mm.
• The surface of the refractory panel has
eroded more than 25% of it's original
thickness, or
• When the panel starts to crumble and
fall apart in chunks.
To prevent the issue from happening
and prolong the life of your internal
panels, the homeowner should "burn in"
the refractory panels in the new
appliance by building small kindling fires
to begin with and then gradually
working up to a larger fire. When adding
more fuel to the fire, caution should be
used to prevent excessive mechanical
damage to the panels.
ACR Heat Products bears no
responsibility for the loss or damage of
any kind to the internal panels during or
after installation or during the normal
operation of the appliance.
Use only replacement parts
recommended by the manufacturer.

Issues Using Your Stove
The flue system has two main functions:
• To safely remove the smoke, fumes and combustion gases from the appliance.
• To provide a sufficient amount of flue draught in the appliance to ensure the correct amount of combustible air is introduced to
keep the fire burning.
• The flue draught is caused by rising hot gases when the appliance is lit.
• Tar and creosote are 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.
For advice on the correction of persistent flue problems consult a qualified competent engineer before continuing to use
the appliance.
