Properly  installed,  operated  and  maintained,  this  appliance  will  not  emit  fumes  into  the  dwelling.
However  occasional  fumes  from  de-ashing  and  re-fuelling  may  occur.  Persistent  fume  emission  is
potentially  dangerous  and  must  not  be  tolerated.  If  fume  emission  does  persist,  open  doors  and
windows  to  ventilate  the  room.  Let  the  fire  burn  out  or  eject  and  safely  dispose  of  fuel  from  the
appliance. Once the fire is cold, check the flue and chimney for blockages and clean if required. Do 
not attempt to relight the fire until the cause of the fume emission has been identified and corrected.
Seek expert advice if necessary.

Do not fit an extractor fan in the same room as the appliance.

An adequate air supply for combustion and ventilation is required. As this stove does not exceed 5.0
kW nominal heat output (Refer to Building Regulations Document J) a purpose provided air vent is not
normally required. However, in certain circumstances a purpose provided air vent may be necessary –
for  example,  small  or  tightly  sealed  rooms.  Air  openings  provided  for  this  purpose  must  not  be
restricted.

It is important that flue ways are cleaned frequently and the chimney swept regularly. Also the stove
must  be  maintained in  good mechanical  order.  Regular  sweeping  means  at  least  once  per  year for
smokeless fuel and a minimum of twice per year for other fuels.

If the chimney was previously used for an open fire, it is possible that the higher flue gas temperatures
generated  by  the  stove  may  loosen  deposits  that  were  firmly  adhering  to  the  inner  surface  of  the 
chimney  and  cause  blockage  of  the  fluepipe.  We  recommend  that  in  such  a  situation  a  second
sweeping  of  the  chimney  should  be  carried  out  within  one  month  of  regular  use  of  the  stove  after
installation. Also, lock or remove any existing dampers in the flueway.

Should it be likely that children, aged or infirm people approach the fire, then a fireguard should be
fitted.

Avoid the use of aerosol sprays in the vicinity of the stove when it is in operation.

This  appliance  must  be  installed  as  per  these  instructions  and  regulations  complied  with.  No 
modifications or alterations of any kind are permitted.

 

 

The installer has a responsibility under the Health and Safety at Work Act 1974 to provide for the safety of 
persons carrying out the installation. Attention is drawn to the fact that fire cement is caustic and hands must 
be washed thoroughly after use. The appliance is heavy and care must be taken during handling. Although 
the appliance does not contain asbestos products, it is possible that asbestos may be disturbed in existing 
installations and every precaution must be taken. 

These instructions give a guide for the installation of the appliance but in no way absolves the installer from 
responsibilities to confirm to British Standards, in particular BS

need to be complied with when installing the appliance.

GENERAL SAFETY NOTES 

 

This successful operation of these appliances relies on the adequate performance of the chimney to which it 

is connected. The chimney must: 

Have an internal cross section of no less than 320cm

2

 (200mm dia). If a flue liner is used it should be 

5'' diameter (125mm) and suitable for solid fuel.

Be a minimum 4.6m high from hearth level to pot.

Be terminated at least 1m above roof level so that the chimney does not terminate in a pressure zone 

(see Fig.2).

Be free from cracks, severe bends, voids and obstructions.

Be connected to this one appliance only.

New chimneys must be built accordance with local Building Regulations.

New chimneys must be tested in accordance with HETAS requirements.

If this stove is installed as a freestanding appliance, it should not support any part of the chimney.

Voids in the chimney should be avoided, as these will prevent a steady flue draught.

The stove flue pipe should pass beyond the narrowing of the chimney (see Fig. 1).

Consideration should be given to falling soot. For rear outlet stoves it may be necessary to provide a

soot  catchment  area  in  the  flue  pipe  so  that  soot  does  not  settle  in  the  path  of  the  flue  gases. The

optional  rear  flue  box  attachment  available  from  ESSE  has  a  detachable  base  that  allows  for  fallen

soot to be removed (See Fig.1).

A flue/chimney access point may also be required so that the state of the chimney can be checked

and any fallen soot removed.

External flues must be insulated to prevent heat loss.,
