CE Mark
The CE mark on this appliance shows compliance with:
1. Directive 90/396/EEC on the approximation of the laws of the Member States relating to appliances burning gaseous fuels.
2. Directive 89/336/EEC on the approximation of the Laws of the Member States relating to electromagnetic compatibility.

INFORMATION FOR THE INSTALLER AND SERVICE ENGINEER.
Under Section 6 of the Health and Safety at Work Act 1974, we are required to provide information on substances hazardous to
health.
The Adhesives and sealants used in this appliance are cured and give no known hazard in this state.
REFRACTORY CERAMIC FIBRE
This product uses fuel effect Pieces containing Refractory Ceramic Fibre (RCF), which are man-made vitreous silicate fibres.
Excessive exposure to these materials may cause temporary irritation to eyes, skin and respiratory tract, consequently, it makes
sense to take care when handling these articles to ensure that the release of dust is kept to a minimum.
To ensure that the release of fibres from these RCF articles is kept to a minimum, during installation and servicing we recommend
that you use a HEPA filtered vacuum to remove any dust and soot accumulated in and around the fire before and after working on
the fire. When replacing these articles we recommend that the replaced items are not broken up, but are sealed within heavy duty
polythenebags, clearlylabelled asRCF waste. Thisis notclassified as“hazardous waste”and maybe disposedof ata tippingsite
licensed for the disposal of industrial waste. Protective clothing is not required when handling these articles, 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.
INSULATION and SEALS
Ceramic fibre and glass fibre used in insulation panels rope and gaskets.
These can cause irritation to skin, eyes and the respiratory tract.
If you have a history of skin complaint you may be susceptible to irritation. High dust levels are usual only if the material is broken.
Normalhandlingshouldnotcausediscomfort,butfollownormalgoodhygieneandwashyourhandsbeforeeating,drinkingorgoing
to the lavatory.
If you do suffer irritation to the eyes or severe irritation to the skin seek medical attention.

2 Preparation & Flue Installation
Method 2
Refer to diagram 2.4.
This allows for the fire to be installed in the inner skin of the
cavity wall.
Note:Thebackofthefireortheinsulationblanketmustnot
intrude into the cavity space.
It requires the extraction of a section of the inner cavity wall.
Careshouldbetakenwhenundertakingthiswork,astheremay
be cavity wall insulation present. Some insulation is of a

precautions not be taken.
Mark out the area required either side of the centre line. This
should just be enough to allow the fire to fit in easily, see
diagram 2.3.
Important:Theopeningcanbecuttotheminimumdimensions,
only if no combustible material is within 75mm of the fire. Only
in this case may the insulation blanket on top of the fire be
removed to enable the fire to fit in.
Remove the required section and strengthen with a suitable
lintel (if necessary) over the opening.
The cavity space of both sides and the top must be closed with
a non-combustible material.

2.5 Timber Frame Building
The two installation methods as described may be used to
install the appliance in a timber framed building provided
adequate protection to combustible material is made.
It should be fitted in accordance with the Institute of Gas
Engineers document IGE/UP/7/1998. If in doubt seek advice
from the local gas undertaking or Hepworth Heating Ltd.
Method 1
Theflueopeningthroughthetimbersectionofthewallwillneed
to have a non-combustible lining of at least 200mm minimum

10mm into the cavity of the wall, see diagram 2.5.
Note:Ifbothinnerandouterleafsareconstructedoftimber,the
non-combustiblefluelinerwillneedtoextendthefullwidthofthe

Refer to Section 2.6 for marking out and positioning of fire, flue
and flue terminal.
Note: Before this work is carried out, consideration should be
giventothepositionofthetimberstudding,asthiscouldinvolve
extraworkinremovingstudworkandifnecessary,strengthening
the remainder.
Using a suitable drill or brace and bit, make a pilot hole, at the
center of the marked out flue orifice, through the timber
construction, changing to a drill and masonary bit to continue
though the outer brick leaf of the wall.
Carefullycutoutandremovetheplasterboardofthemarkedout

If there is a vapour barrier behind the plasterboard, this should

Removeanyinsulationmaterialandusingthelinerasatemplate,
markoutontheinnertimbersheathing,thecircumferenceofthe
liner.
Someinsulationisofa granularnature,resultinginaconsiderable
loss of it, should precautions not be taken.
Withbraceandbit,makeseveralholesaroundthecircumference
and using a suitable narrow bladed saw, cut out the hole.
On the outside wall, finish making the flue orifice, using a
suitable core drill, to receive the 101mm diameter flue.
Insert the flue liner into the inner wall leaf making sure it does
not intrude more than 10mm into the cavity space, and mark it
12mm from the plasterboard to allow for the insulation board,
cut to size.
Seal inner and outer edges of the flue liner with a non-setting
thermal mastic.
An insulation board measuring 780mm x 690mm x 12mm will
havetobefittedtotheinnerwallwithaholecut toaccommodate
the flue liner, see diagram 2.5.
Secure fire insulation board to wall.

2 Preparation & Flue Installation
Method 2
Should Method 2 be used, which requires the removal of a
sectionof theinnertimber leafofthe wall,careshould betaken
as not to weaken the structure. If any part of the vertical
studworkhastoberemoved,theremainingpartofthestudwork
should be supported by fitting a cross member above the
proposed opening.
Note:Thebackofthefireortheinsulationblanketmustnot
intrude into the cavity space.
Careshouldbetakenwhenundertakingthiswork,astheremay
be cavity wall insulation present. Some insulation is of a
granular nature, resulting in a considerable loss of it, should
precautions not be taken.
Refer to Section 2.6 for marking out and positioning of fire, flue
and flue terminal.
Where combustible material is near to the fire, an air gap of
25mm minimum must be maintained all round the insulation
blanket
Mark out the area required either side of the centre line.
Note:Allowforthethicknessofthefireinsulationblanketandair
gap when undertaking this work.
Cut out and remove the required section and strengthen (if
necessary).
The cavity space of both sides and the top must be closed with
a non-combustible material.
The finished opening will also need to be lined with suitable
insulation to protect inner leaf of wall from the heat of the
appliance.
Note:Thenon-combustible fluelinerisnot requiredifMethod 2
is used, unless the outer wall leaf is of timber construction.
An insulation board measuring 780mm x 690mm x 12mm will
have to be fitted to the inner wall with a opening cut to
accommodate the fire assembly.
Secure fire insulation board to wall.

Note: If timber framed building, refer back to Section 2.5.
Using a suitable core drill cut the flue hole horizontal to the

cavity leaf should be carried out at this stage.
Note:Removeanybrickdebrisandcavityinsulationifnecessary.
Remove power flue terminal from its packing.
Remove the securing screws and take off flue hood, see
diagram 2.6.
Undo the three nuts holding fan assembly to wall plate, see
diagram 2.7, and remove.
Fix the flue manifold adaptor to the flue manifold at the rear of
fire using two self tapping screws provided, see diagram 2.8.

WIRING.
WARNING:When routingelectrical cable,avoidplacing itnear
potentially hot surfaces and against sharp edges.
4.1 Fan Switch
The switch to turn the fan “ON” and “OFF”, should be situated
on the wall, at a suitable position for the user to operate.
See diagram 8.4 for wiring details.
Insert fan switch plug into "ON" / "OFF" wall switch connector,

Connection to the mains should be through the plug supplied
and connected to the mains socket, see diagram 4.1.
4.3 Testing - Electrical
Checks to ensure electrical safety must be carried out by a
competent person.
After installation of the system, preliminary electrical system
checks as below should be carried out,
1. Test the earth continuity and short circuit of all cables.
2. Test insulation resistance to earth of mains cable.
3. Test the polarity of the mains. Diagram 4.1
