Encore Multi-Fuel Heater

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 in-
cluded below. There are no specific minimum clearanc-
es 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 noncombus-
tible materials is specified in section 2 of Document ‘J’,
in relation to the clearance of the appliance from the
surface. As a general rule, the thickness of solid non-
combustible material forming the recess of a fireplace is
a minimum of 200 mm.
Minimum rear clearance from combustible walls
(e.g. timber framed or studded walls) 840 mm (33”)
measured from the rear edge of the stove top. (Fig.
12, B)

1220 mm (48”).
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 13.
