backwards, leaving a smoke escape gap at the front of the
plate just behind the top of the door frame.
5) Check that the intended location of the stove is safely
accessible and that all adjacent walls, oors and objects
(adjacent to the stove) and their substructures (ie. stud
walls) are either fully non-combustible or are located
beyond the minimum clearances required (See ‘Distances
to Combustibles’ - on pages18+ (diagrams illustrating
distances to combustibles in relevant scenarios).
6) Check that the hearth and its substructure are suitably
strong and stable if taking the weight of the stove. The
hearth needs to be made of suitable non-combustible
material.
7) Ensure the hearth is compliant with relevant Building
Regulations or any HETAS or British Standards installation
guidlelines relating to the specic structure type, for exam-
ple if being installed into a boat or cabin, glamping pod etc
To comply with domestic Building Regulations in England
and Wales, the aesthetic hearth needs to be a minimum
12mm thick, needs to extend at least 150mm either side of
the appliance, and at least 225mm in front of the appliance.
8) Chimney/Flue -
a) The ue system should be checked for draught
strength - a minimum ue draught of 10Pa is required,
and a maximum of 20Pa, measured approximately
500mm above the stove ue collar via a pre-drilled
draught gauge access in the rst section of ue pipe.
This measurement should be taken when the ue is pre-
warmed. Flue systems of excessive strength should be
tted with a balanced ‘ue draught regulator’.
b) A ue system of 4.5 metres height (from the top of the
stove) would normally provide ‘standard’ or ‘mid-range’
draught strength when using insulated 5” internal diameter
ue (assuming there are no other external factors which
counteract the ue draught strength).
c) Any ue system tted in a domestic dwelling or
commercial building needs to be compliant with the
current England and Wales Building Regulations
specications for a Class1 Chimney. Existing brick and
clay-lined chimneys should be tted with a suitable
stainless steel liner ideally of 5” (125mm) diameter.
The maximum internal ue diameter used should be 6”
(150mm). Suitable insulation between the inner walls of
the chimney and the liner should be used.
Additional information for small space/ ‘glamping’ and
boat installations:
When installed into small spaces such as tents, yurts,
cabins, sheds and other alternative non-permanent non-
domestic structures, we recommend using 4” insulated
chimney system and a minimum 3m ue height.
See specic guidelines published by HETAS for installation
into this type of accommodation.
9) Ventilation - The appliance requires room ventilation
when used as a wood-burner. - This is air which is drawn
from the outside to replace air in the room consumed by
the burning of the re. Houses built before 2008 are likely
to have enough natural ventilation to supply this air, unless
the house has had extensive draught proong works
carried out. For more modern houses or those with minimal
natural ventilation (air permeability less than 5.0 m3/h.m2),
an air vent with equivalent-free-surface area of at least
2750mm ² needs to be used. In any case, additional rules
for vents apply when tting the system with ue draught
stabiliser (if in doubt consult either HETAS, Building
Regulations Document J, or your engineer).
For well insulated or well sealed small spaces such as
cabins, glamping pods, boats etc, ensure adequate
ventilation to the space or use the direct air supply option
connecting the back of the stove to the outside. - See
section in this manual on installation of external air
connection.
10) CO Alarm, -The tting of a CO alarm is an essential
requirement and should be tted in the same room as
the stove. Existing alarms should be checked for current
suitability. If in doubt t a suitable good quality new alarm.
