1. APPLIANCE D ATA
1.1 This product uses a fuel effect piece containing
Refractory Cer amic Fibres (RCF ), which are man-made
vitreous silicate fibres. Excessive exposure to this
material ma y c a use temporary ir ritation to eyes, skin and
respiratory tract. Consequently, it makes sense to take
care when h andlin g th is article to en su re that the relea se
of dust is kept to a minimum. To ensure that the release
of fibres from this RCF article is kept to a minimum,
during installation and servicing we recommend that you
use a HEPA fi ltered vacu um to remove any dust and
soot accumulated in and around the fire before and after
working on the fire. When replacing this article we
recommend tha t the replaced i tem i s n o t br ok en up, but
is sealed with in a heavy duty polythene bag, c learly
labelled as RCF waste. This is not classified as
“hazardous waste” and may be disposed of at a tipping
site lic ensed for t he disposal of industri al waste.
Protective clothing is not required when handling this
article, but we recommend you follow the normal
hygiene rules of not smoking, eating or drinking in the
work area and always wash your hands before eating or
drinking.
This appliance does not contain any component
manufac tu red from asbestos or asbestos rela ted
products.

the back panel near the bottom l eft corner. There is also
a label giving a serial number and the appliance G.C

2. GENERAL INSTALLATION REQUIREMENTS
2.1 The installation should comply with the rules in
force.
In your own interest and that of safety, in the United
Kingdom, it is the law that all gas appliances are installed

Regulations. Failure to install appliances correctly could
lead to prosecution.
The Counci l of Registered Ga s Installer s (CORGI)
requires its members to work to recognised standards.
The installation must be in accordance with these
instructions.
In the United Kingdom the installation must also be in
accordance with:
a) All the relevant parts of local regulations.
b) The Building Regulations issued by the
Department of th e En vironment or th e Buildin g
Standa rds (Scotland) ( Co nsolidation) Reg ulatio ns issued
by the Scottish Development Department.
c) All relevant codes of practice.
d) The relevant parts of the current editions of the
following British Standards:BS 715
BS 1251
BS 1289 Part 1

BS 5440 Part 2
BS 5871 Part 1
BS 6461 Part 1
BS 6891
In the Republic of Ireland the installation must also
conform with the national and local regulations in force.
2.2 The appliance must not stand on a carpet or any
other combustibl e ma terial.
If a panel h a s to be f i tted to the fireplace opening to meet
the requi red opening si zes shown below, it mu st be
made of non-combustible material.

The appliance must be mounted on a non-combustible
hearth (N.B. conglomerate marble hearths are
considered as non-combustible). The hearth must be at
least 710mm wide x 300mm d eep. The hearth ma terial
must be at least 12mm thic k. Th e periphery of th e
hearth (or fender) should be at least 50mm above floor

a cross-sectional a rea of 13,000mm
2
. The current
revision of the standa rd requi res 16,500mm
2
. This
appliance is suitable in both cases.
The chimney should be on or two storeys h igh but not
less than 3m vertical height and be correctly terminated.
No mortar f angs between the bloc k s sh ou ld be extruded
into the flueway. If raking blocks are used, they must be
fitted in accordanc e with the manufacturer’ s
instructions. Mortar must not be allowed to drop down
and accu mulate in th e r aked positions.
The firepl a c e opening must be with i n the following
dimensions:
Width: Max. 423mm
Min: 305mm
Height Max: 610mm*
Min. 610mm*

heights above 610mm will leave the closure plate and
sealing ta pe vi sible above the appl iance.
2.4. Flues
The flu e m ust be clear of any o bst ruction and its base
must be clear of debris.
The flue must be completely sealed so that combustion
products do not c ome i nto contact with combustible
material s ou tsi d e the chimney.
Suitable flues are as follows:(a) 225mm x 225mm conventi onal brick f lue. If a
flue li ner is used, it must be a mini mum of 127mm (5in)
diameter. The liner must be sealed to th e surrounding

position.
2.4.4. If the appliance is intended to be installed to a
chimney which was previously used for solid fuel, the
flue must be swept clean prior to installation. All flues
should be inspec te d for sou ndness and freed o m from
blockages.
2.5 If the fir epl ace opening is a n underf loor drau ght

close to a heating appliance. Please bear this in mind
when installing.
2.13. An extra c tor fan may on l y be used in the same
room as this appliance, or in any area from which
ventilation for the appliance is taken, if it does not affect
the safe performance of the appliance. Note the spillage
test requirements detailed further on in this manual. If
the fan is likely to affect the appliance, the appliance
must not be installed unless the fan is permanently
