Clearances
As with any solid fuel heating stove, extremely high
surface temperatures can occur, particularly in the
event of uncontrolled operation, e.g. if the doors
are inadvertently left open. It is crucial that suf-
ficient clearances are allowed to any combustible
surfaces, e.g. wooden mantels or lintels, and to
timber framed (studded) walls even if they are faced
with noncombustible board. Detailed information
on fireplace and hearth construction is provided
in section 2 of Document J, all installations must
comply with these requirements or with the relevant
National or local building standards.
Clearances to timber framed (studded) walls are includ-
ed below. There are no specific minimum clearances
to solid noncombustible, surfaces (e.g. the sides and
rear of Inglenook fire openings constructed from solid
masonry) other than to allow safe access to the controls
of the stove. For this reason minimum side clearances
of 125 mm, and a minimum rear clearance of 50 mm
are recommended.
Summary of Clearances
Minimum recommended side clearances to non-
combustible surfaces 125 mm (5”).
Minimum recommended rear clearance to noncom-
bustible surfaces 50 mm (2”).
NOTE: The minimum thickness of solid noncombustible
materials is specified in section 2 of Document ‘J’, in
relation to the clearance of the appliance from the sur-
face. As a general rule, the thickness of solid noncom-
surface temperatures can occur, particularly in the
event of uncontrolled operation, e.g. if the doors
are inadvertently left open. It is crucial that suf-
ficient clearances are allowed to any combustible
surfaces, e.g. wooden mantels or lintels, and to

Connecting Flue Pipe - Clearances
Single wall connecting fluepipes can reach extremely
high temperatures; therefore, clearances from the con-
necting fluepipe (chimney connector) must comply with
the requirements of Part J of Building Regulations 2000
(Combustion Appliances and Fuel Storage Systems).
This can be achieved by following the recommenda-
tions of Approved Document ‘J’. These are as shown in
Figure 14.
